    How Long Can Solar Battery Power a House During an Outage?

    When you install a home battery, what you are really doing is providing your home with a backup energy reserve in the case of an outage.

    Whether you have a solar panel system at your home or not, a home battery can be used to store electricity and deliver it to your home appliances and devices. The benefits of a home battery are clear, especially during short or long-term outages, or in areas with Time-of-Use (TOU) rates that make electricity more expensive during peak use hours.

    In this article, we’ll show you how to calculate how long a battery paired with solar can power your house during a power outage, and give you some tips for maximizing your battery usage.

    How long can a solar battery power a house?

    Without running AC or electric heat, a 10 kWh battery alone can power the basic operations of a house for at least 24 hours, and longer with careful budgeting. When paired with solar, battery storage can power more electrical systems and provide backup electricity for even longer.

    In fact, a recent study by the Lawrence Berkeley National Laboratory found that when heating and cooling are excluded:

    “(A) small PVESS with just 10 kWh of storage (at the lower end of sizes currently observed in the market) can fully meet backup needs over a 3-day outage in virtually all U.S. counties and any month of the year.”

    PVESS stands for photovoltaics and energy storage system.

    But exactly how long you can power your home with solar battery storage varies for each home and depends on three main things:

    • Your battery storage capacity
    • The output of your solar system
    • Your electricity needs during an outage

    We’ll show you how to budget your electricity to meet your solar and battery capacity below. First, let’s start with identifying your battery storage capacity.

    Home battery capacity

    Capacity — the amount of energy a battery can story — is one of the main features that influence how long a battery can power a house during a power outage.

    Battery storage capacity is measured in kilowatt hours (kWh) and can vary from as little as 1 kWh to over 10 kWh. Multiple batteries can be combined together to add even more capacity, but a 10 kWh home battery is typical for most homes.

    Check out this video to know more about Kilowatt hours (kWh).

    During a power outage, assuming you have a fully charged home battery, you will be able to use most of the 10 kWh of stored energy. You’ll want to leave a minimum charge of 5-10% on your battery for a couple main reasons:

    • To maintain the health of your battery
    • To start your solar inverters in the morning so you can recharge your battery with solar power

    For a 10 kWh battery, you’ll want to leave at least 0.5 kWh of capacity in reserve at all times. That leaves you with 9.5 kWh to power your home during a power outage.

    On it’s own, 9.5 kWh of battery storage can power essential electrical systems for a day or two. But central air conditioning uses around 3 kWh per hour, which would eat up the entire battery in just over three hours. Let’s see pairing battery with solar can expand your options during a power outage.

    Solar system output

    The beauty of pairing battery storage with solar is that you essentially create your own miniature utility to power your home. This is especially useful during prolonged power outages because unless you have battery storage, your solar system will be turned off by the local utility to prevent the backflow of electricity from injuring workers trying to repair the grid.

    But if you have battery storage, your system can operate independently when the grid is down. This is called “islanding.”

    How electricity does a solar system produce?

    Solar panel systems are measured in kilowatts (kW) that represent the amount of energy the system can produce in an hour of peak sunlight. So a 5 kW solar system can produce 5 kWh of electricity per hour in ideal conditions. But since conditions aren’t always ideal, we typically assume a performance ratio of 75%.

    The average number of peak sunlight hours per day varies from 3.5 to 5.5 in the US. Multiple the system capacity by sunlight hours and 0.75 to find the daily output of a solar system.

    For example, here’s how you would find the daily output of a 5 kW solar system getting 4.5 peak sunlight hours per day equals:

    5 kW solar system x 4.5 sunlight hours per day x 0.75 performance rating = 16.875 kWh per day

    In many cases, that’s more than enough to power essential electrical systems and recharge a 10 kW battery to use overnight. But electricity needs vary from home to home, so let’s run through a some common appliances and how much energy they use.

    Your electricity needs during a power outage

    How long solar battery storage can run your home depends how much electricity you use. And how much electricity you use depends on which appliances and systems you’re running.

    During a power outage, it’s recommended to budget electricity for the most necessary things first and then make a plan for the remainder capacity. For many homeowners, the list of priorities includes:

    • Refrigerator
    • Kitchen and cooking
    • Water heating
    • Lights
    • TV and device charging
    • Heating and cooling

    Now, heating and cooling is last on the list not because it isn’t important, but because these operations take so much electricity they’ll likely have to be limited regardless of your battery capacity. So the wise move here is to budget your essentials first, and then get a sense of how much battery capacity is left for heating and cooling.

    Note: If you have a gas furnace, you won’t need much electricity to keep the heat on.

    Let’s run through an example scenario of powering essential systems during a 24-hour power outage to get an idea of how much solar and battery capacity you’ll need.

    Use the tables below as an a la carte menu to create your own battery storage budget.

    Refrigerator: 1.5 kWh per day

    Model Energy use
    “>Older 15-cubic foot unit (1996) “>5 kWh per day
    “>Newer ENERGY STAR 17-cubic foot unit “>1.16 kWh per day

    A refrigerator is among most important things to power during an outage so that you can avoid having your food and drink go to waste.

    If you have a modern, energy star approved model, your refrigerator is using around 1-2 kWh of electricity a day. If your fridge lived through Y2K, you might be looking at closer to 5 kWh per day.

    Refrigerator electricity usage can be minimized by opening the door less and raising the temperature slightly. If you are preparing for a planned Public Safety Power Shutoff (PSPS), set the temperature very low before the shutoff event, and then set it to a higher temperature once the grid power goes out. That way the fridge starts cold and you can devote less battery capacity to power it during the outage.

    Let’s say you have a relatively modern ENERGY STAR certified fridge that uses 1.5 kWh per day.

    Running total: 1.5 kWh

    Kitchen and cooking: 1 kWh per day

    Appliance Energy use
    “>Electric oven “>2.3 kWh per hour
    “>Oven: surface “>1.1.5 kWh per hour
    “>Microwave oven “>0.12 kWh per 5 minutes
    “>Coffee maker “>

    Even during a power outage, people gotta eat. And in a large enough outage, it may not be practical to eat out or order delivery.

    Let’s say you make a pot of coffee and toast in the morning (0.2 kWh), microwaved some leftovers for lunch (.12 kWh), and baked a frozen pizza for dinner (0.75 kWh) because your trying to clear out the freezer. That amounts to just over 1 kWh throughout the day.

    Running total: 2.5 kWh

    Electric water heating: 2.5 kWh a day

    Appliance Energy use
    “>Electric water heater “>4-5 kWh per day (running 2-3 hours)
    “>Heat pump water heater (50-75 gallon) “>~2.5 kWh per day

    Water heating accounts for an average of 18% of the total energy used in the household. or around 162 kWh per month. On a normal day, a water heater runs for around 2 to 3 hours a day, which means that it will consume roughly 4-5 kWh of electricity a day. Heat pump water heaters are more efficient and can run on around 2.5 kWh per day.

    But power outages are not normal days. To save electricity, you may want to skip or shorten your shower, wash your hands and rise your dishes with cold water, and hold off on laundry for a day or two.

    And if you have a gas-powered water heater, water heating is a non-issue in terms of battery use.

    But for the sake of argument, let’s say you put on some extra deodorant and limit your water heating use to 2.5 kWh per day.

    Running total: 5 kWh

    Lights: 1 kWh per day

    Bulb type Energy use
    CFL/LED (8 W) equivalent to 25 W incandescent 0.008 kWh per hour
    CFL/LED (15 W) equivalent to 60 W incandescent 0.015 kWh per hour
    CFL/LED (27 W) equivalent to 100 W incandescent 0.027 kWh per hour
    CFL/LED (38 W) equivalent to 150 W incandescent 0.038 kWh per hour

    Compared to larger appliances, lights require very little electricity, especially if you have compact fluorescent (CFL) or LED bulbs. Even at the high end, a 38W LED bulb or 150 W incandescent bulb uses just 0.038 kWh per hour.

    So if you budget 1 kWh of battery storage per day to lighting, you could run 26 bulbs for 1 hour each — more than enough to provide light for trips to the bathroom, closet, and getting ready for bed.

    Remaining battery budget: 6 kWh

    TV and device charging: 2 kWh

    Device Energy use
    Wi-Fi router 0.024 kWh per day
    “>Modern TV: LED/OLED 4k or 1080P HDTV (20″ to 70″) “>0.014 to 0.18 kWh per hour
    “>TV: Plasma (40″ to 50″) “>0.4 to 0.48 kWh per hour
    “>Desktop computer “>0.06 kWh per hour
    “>Laptop computer “>0.02-0.05 kWh per hour
    “>Tablet “>0.032 kWh per day

    Let’s be honest, one of the worst parts of power outages is going without internet and TV. Sure, you try to read a book for an hour or two, but that familiar glow is calling your name.

    To keep the Wi-Fi on, you’ll need about 0.024 kWh. If you work from home, you can run your laptop for 8 hours for another 0.4 kWh. And if you want to wind-down with a movie or 3-hour Netflix binge, you’ll need another 0.54 kWh.

    That adds up to 1.18 kWh, but we’ll round up to 2 kWh to account for phone charging and multiple devices running at once.

    Remaining battery budget: 8 kWh

    Air Heating and Cooling: Variable

    Appliance Energy use
    “>Heating
    “>Electric furnace (with fan) “>10.5 kWh per hour
    “>Portable heater “>1.5 kWh per hour
    “>Baseboard heater (6-foot unit) “>1.5 kWh per hour
    Cooling
    “>Window/Wall AC (8k to 18k BTU) “>0.73 to 1.8 kWh per hour
    “>Central AC (3 ton – 12 SEER) “>3.0 kWh per hour
    “>Pedestal fan “>0.03 kWh per hour
    “>Ceiling fan “>0.025-0.075 kWh per hour

    As you can see from the table, heating and cooling take a lot of electricity. So if you only had a 10 kWh battery and no solar, you’d have maybe 2 kWh to budget for running fans or space heaters.

    But with a battery charged by solar, you would have much more electricity to spare for fans and space heaters — perhaps even enough to run central AC for a few hours, depending on your equipment.

    Medical equipment

    Device Energy use
    “>Nebulizer “>1 kWh per hour
    “>Oxygen concentrator “>0.46 kWh per hour
    “>Sleep apnea machine (CPAP) “>0.2 kWh per hour

    Another thing to consider is powering medical equipment during a power outage. Certain equipment, like a nebulizer, requires a significant amount of electricity and could eat through 10kWh of battery very quickly.

    Is getting a solar battery worth it?

    Weather-related power outages in the US increased roughly 78% from 2011 to 2021, and are becoming a reality for more homeowners. If you like clean, quiet, and hands-free backup energy that can power your home for several days during outages, then solar and battery are totally worth it. Not only can battery keep your home powered, it can keep your local grid running, as we saw in California in September 2022.

    In addition to providing backup power during outages, solar and battery can reduce your energy costs by shifting your power usage to off-peak hours when electricity is much cheaper (up to 20 cents per kWh!)

    And, of course, there are the local and global impacts of reducing fossil fuel that pollute the air and contribute to climate change.

    I recently purchased my home and it did not have an EV charger nor solar panels on the roof. We worked with Inner City Skyline in the past, and now since solar came down, we had to get it for our new home in Encino. Another flawless installation. John and I coordinated everything so well.

    .6kW Solar System Cost

    The state you live in and the amount of rebate you are eligible for also play a factor.

    .6 kW Solar System Price by State

    State6.6kW Price

    kW Average Yearly Savings

    How Many Panels Are Needed?

    A typical 6kw solar system will require 18 x 370W solar panels, each measuring 1m by 1.7m.

    However, panel size and the number of panels may vary from manufacturer to manufacturer. Some manufacturers do manage to make solar panels with higher outputs and therefore need fewer panels for a given output rating. You will need to check your north-facing roof space to see which option is best for you.

    Going by the above estimates, you will need around 31 m2 of north-facing roof space.

    Solar rebate for a 6.6kW system

    The solar rebate you receive for a 6.6kW solar system will depend on the state you live in. Different states are in different STC zones which allow different rebate amount.

    Zones: 1, 2, 3States: NSW, QLD, WA, SA, NT, ACTSTC’s: 72Rebate: 2,873

    How Do I Know If The 6kwh System Is the Right Size for Me?

    When selecting a solar panel system it’s all about the average Australian reducing their power bills by 90% or more. Ideally, a standard single-phase 6kw system should cover you if you consume an average of 26kWh of power per day. You will need to check your power consumption over the last 12 months.

    Some other factors you should use to know if a 6kw system is right for you might include:

    Your Household Energy Consumption

    Some people prefer to have as much renewable energy as they can afford to reduce their electrical bills and contribute to the green initiative. If you fall into this category and have low to moderate daily power consumption, then a 6Kw solar system or higher could be the best for you. Keep in mind that the higher you go, the bigger the discount you get courtesy of the Australian STC solar rebate system.

    A 6kw system is perfect for you if you use less than 26kWh of power per day. Below is a breakdown of common appliances and other electrical things you could run with a 6kw system. Keep in mind that these are just estimates, and solar output may vary according to weather conditions in your city.

    Cost

    Can you afford a 6Kw system? If yes, does it make sense to you based on your daily consumption? If you can make sense of the figures without factoring in the feed-in tariffs, then you are good to go. As mentioned earlier, installing a solar system whose output you can use is more attractive in terms of the payback periods.

    Location

    If you live in territories with lots of year-round sunshine, a higher wattage solar system might make a lot of sense. The favorable weather will not only make the solar system cheaper to install, but you will have better returns with surplus output from your solar system.

    As an example, if you live in Brisbane and consume 22kWh of power per day, you would feed about 17Kwh to the grid and benefit from the feed-in tariffs at 8c per Kwh. This is because 70% of household power is consumed at night, but all solar power is produced through the day.

    Roof space

    This actually needs to be the first thing you check. Having enough North facing roof space is paramount for this all to work. IN some cases you can get away with it facing on slightly different angles, but you will need to consult a professional solar installer first before committing to anything.

    How Much Power Will A 6kwh System Produce?

    Energy outputs from solar systems tend to vary depending on the location they are installed. On average, a 6kwh solar system should produce at least 25Kwh in favorable weather. However, 6Kwh solar outputs are best estimated by location using climate information for solar energy from the Australian Bureau of Meteorology’s datasheets and solar vendor data as follows:

    City/LocationEstimated 6Kw solar daily energy output

    The reason for the different figures based on location is primarily associated with daily solar radiation levels. However, other factors do affect individual solar outputs, such as:

    Panel orientation and tilt – Solar panel orientation and tilt will affect how much power a system can generate. It’s, therefore, important to have enough space on the correct side of your roof for the panels.

    Different regions may have varying tilt and orientation requirements for solar panels based on solar radiation data. That said, you don’t have to worry about this particular requirement. The solar company will most likely conduct its assessment and place the solar panels at an optimal position for maximum yield.

    Solar system quality – Good quality solar panel systems are not the same in terms of quality and efficiency. For instance, a high-quality Smart energy solar kit would have slightly higher yields than a lower quality standard kit. Additionally, most solar power systems usually come with an output tolerance of plus or minus two units of their watt rating.

    Inverter setup and efficiency – Sometimes, the inverter might affect how much energy you get from a solar system. Your installer may suggest that you get a lower-wattage inverter to overclock the system and optimize solar performance.

    Shading – Trees and large buildings blocking direct sun rays to your residence will affect how much power you can generate with your daily solar output. Talk to the solar installer on ways you can mitigate any shading issues to get the best out of your solar system.

    14kw, solar, system, cost

    Panel Maintenance – over time, dust, debris, and other foreign objects will accumulate on your solar power system. Proper solar panel maintenance is, therefore, a contributing factor to solar system outputs regardless of the rating or radiation levels.

    Note: Too much dirt and debris will reduce the output by a small margin, while physical damage such as cracks will have a significant impact.

    Ambient temperature – High temperatures hurt solar power system performance. Depending on installation type and panel temperature coefficients, you may get varying solar outputs when temperatures get to certain levels. It’s therefore important to explore the prevailing temperatures in your location and seek some advice from the installer on the best installation type for optimal performance.

    Loss – As with most single-phase electrical connections, there will be a negligible loss in the DC and AC cabling that will affect your terminal solar output. This varies from installation to installation based on cabling length, interference, and quality.

    Will I Need A 6Kwh Or A 6.6kW Solar System?

    Many people find it hard to choose between the overly popular 6.6Kwh and a 6kW solar system. Personal preferences aside, the 6.6kW solar systems might be a more sensible option for a number of reasons such as:

    There is little price difference in final pricing, including installation for both systems. This is even when the 6.6Kw solar system kit provides an extra 0.600Kwh to the mix.

    STCs – For reasons best known to the regulators, going for the slightly bigger 6.6Kwh system will give you more STCs (quite a margin between them). For instance, a consumer buying a 6.6Kw solar system in Western Shore, Tasmania, will receive 62 STCs. In contrast, the same consumer would receive 56 STCs for a 6Kwh system.

    Almost similar panel count – Again, there is not much difference in panel count between a 6.6Kwh solar kit and a 6Kwh Kit. Some vendors will sell both systems with a maximum of 20 solar panels, albeit with different rated outputs.

    That said, going for a 6Kwh system may make a lot of sense for many reasons, such as your power consumption and payback period. The 6Kwh solar system has a slightly shorter payback time than its close counterpart. However, it’s also important to note that payback times depend on your energy consumption numbers, such as the ratio between the solar energy consumed vs. that coming from the grid.

    Will I Need an Inverter?

    An inverter is required for any kind of solar power system to convert DC from the solar panels to usable AC commonly used in electrical equipment. The great news is a 5Kw inverter would suffice for a 6.6kw solar systems. This means the price will be cheaper as you won’t have to pony up for a larger inverter. This is because a 5kw inverter can be “over-clocked” quite safely to handle 6kw solar system power loads.

    Why not a 6kW inverter?

    Well in short it is cheaper. A 6kw inverter is about 30% more expensive. The 5kW inverter has the capacity to do the job easily, and you save money in the process. It’s cheap, so it’s a win-win.

    Solar Panels in Ireland: What Solar Panels Types Are There?

    Solar panels have been touted as a green alternative to traditional energy sources for decades, but how do they work? Amongst all the hype it can be difficult to know if solar panels are right for your home, and which type would be better suited to your property and the needs of your household. We cover all this and more in our complete guide to solar energy in Ireland.

    How Do Solar Panels Work?

    Solar panels in Ireland can not only help you save on your electricity bills and can even potentially earn you some extra income, but are they effective?

    What Are the Main Types of Solar Panels in Ireland

    All three systems capture the sun’s rays and transform this energy either into electricity (PV solar panels) or heat (thermal solar panels). The keyword here is sun ‘rays’! This means, your panels will still harvest energy in the winter, on cloudy, or rainy days; something we have a lot of in Ireland! The only time they will not work is at night.

    Did you know? The sunnier the day, the more efficient or more energy you will receive from your solar panels. They will still work on rainy days, and even without direct sunlight, just not as efficiently.

    What Are Photovoltaic Solar Panels?

    PV (photovoltaic solar panels), convert light into electricity by using material that exhibits the photovoltaic effect. PV solar panels produce electricity via solar cells, although this electricity can also be diverted to heat hot water cylinders. The main difference between PV solar panels, thermodynamic, and solar thermal panels is that PV panels run on light, while thermodynamic and solar panels run on heat.

    In Ireland, PV solar panels can cost upwards of €4,000 for a quality system including panels, batteries, and installation, before taking into account any government grants or tax incentives. The more panels you buy, the cheaper each panel is. Electric Ireland’s solar cells offering is priced at €5,200 to install 6 solar panels (covering 10 square metres) with a diverter to heat hot water costing €510 (all quoted are inclusive of VAT).

    What is the photovoltaic effect? The photovoltaic effect is a well-studied phenomenon in physics and chemistry where electric current is created by exposing solar cells to light. When enough light is absorbed by the cells, they become “excited” and electrons move around inside the material, releasing energy.

    Financial Advantages of PV Solar Panels

    • Bill Reductions Solar power can reduce, and depending on your setup, even eliminate your electricity bill (as long as you’re not connected to the grid).
    • Export EnergySolar energy can even make you money if you feed your excess electricity to the grid.
    • Not Much Maintenance Required Maintenance of solar panels is minimal, just ensure they are kept free of debris and that nearby or overhanging trees are trimmed back to keep them from shading the panels.
    • Improve House Value A solar panel system should increase the resale value of your house, as home buyers become more aware of BER (Building Energy Rating).
    • Return on InvestmentThe cost of installing a solar panel system could be recovered within 5. 10 years, or less if grants and incentives have been applied.

    Financial Disadvantages of PV Solar Panels

    • High Upfront CostInitial installation of solar PV panels is extremely expensive and can range from €4,000 up to €10,000.
    • Don’t Work at NightSolar panels cannot produce energy at night time.
    • Batteries Batteries for storing solar energy are expensive but will usually make your solar energy much more efficient. Unfortunately, these batteries are not included in the SEAI grants system.
    • Insurance NeededConsidering the size of the initial financial outlay, this makes it imperative to get insurance, further increasing the costs of your PV solar system.

    Environmental Advantages of PV Solar Panels

    • Genuinely RenewableWe will never run out of solar energy in our lifetime.
    • Green EnergySolar power is a renewable, green, clean energy which doesn’t contribute to a country’s carbon emissions.
    • Long LifespanSolar panels can last for up to 40 yearswithout needing fixed, meaning they are much longer lasting than other sources of energy producing less waste.
    • Energy Independence Switching to solar energy will help make Ireland more independent and reduce the need to import fossil fuels.
    • Diverters AvailableIf you don’t have a battery to store surplus energy and are unable, or unwilling, to divert it to the electricity grid, never fear. You can also install a diverter that will send excess electricity to heat your hot water cylinder.

    Environmental Disadvantages of PV Solar Panels

    • Not Always Reliable Solar energy is inconsistent and intemperate weather and long winter nights can mean that being connected to the electricity grid, or having a backup generator, is necessary for when demand is greater than supply.
    • Low Efficiency PV Solar panels only manage to convert about 20% of the sunlight that falls on them to electricity, so there is room for improvement regarding their efficiency.
    • Still Carbon IntensiveSolar power is clean energy but the process used to make solar panels still emits greenhouse gases.
    • Not RecyclableOlder solar panels are not recyclable, although this may change in the future as they become more commonly used.

    Other Advantages of PV Solar Panels

    • Versatile Solar power can be harnessed anywhere in Ireland and doesn’t depend on a connection to an existing network (such as the electricity and gas networks).
    • No Noise Pollution Solar panels are quiet, unlike generators.
    • Easy To InstallSolar panels are easy to install and unobtrusive without causing structural damage to houses.
    • Easy To Add To Solar panel systems can be easily scaled up as energy requirements increase or decrease, by adding additional panels.
    • Homeowner FreedomNo planning permission is necessary to install PV solar panels unless your house is a listed property.

    Other Disadvantages of PV Solar Panels

    • VolatileIf too much of Ireland’s energy production came from solar power, which by nature fluctuates, a means would need to be found to resolve any instability of supply to the electricity grid.
    • Still Need the GridAdditional equipment, such as inverters, is required to connect residential solar panels to the electricity grid.
    • DelicatePV panels are relatively fragile and could be damaged, for example by debris during a storm.

    What Are Thermodynamic Solar Panels?

    Thermodynamic panels, also known as Solar Assisted Heat Pumps, are designed to produce hot water, unlike PV panels which produce electricity. Thermodynamic panels work by circulating extremely cold (-22°C) liquid refrigerant through the panel. This liquid absorbs ambient heat from the air outside the panel and from the infrared rays emitted by the sun.

    The heating element distributes the transferred heat energy into the water in a storage tank. After the heat energy has been transferred, the gas cools and becomes liquid again, and the cycle repeats. Thermodynamic solar panel system installation can cost approximately €4,500 upwards for panels and installation.

    Pros of Thermodynamic Solar Panels

    • EfficientThermodynamic systems tend to come with large storage tanks for hot water and can provide up to 100% of hot water needs.
    • Can Be Placed AnywhereBecause thermodynamic solar panels can absorb heat from the environment, they can be placed anywhere, even in the shade, although for optimal performance they should be in direct sunlight.
    • Work at NightThermodynamic panels can continue to heat water even at night, as long as the temperature outside is above.15°C.
    • Low MaintenanceThermodynamic solar systems require no maintenance and can last for up to 25 years.
    • Can Be Moved AboutIn some cases, thermodynamic heating systems can also be uninstalled and moved to a new house.
    • No Planning PermissionNo planning permission is necessary to install thermodynamic solar panels unless your house is a listed property.

    Cons of Thermodynamic Solar Panels

    • Take Up SpaceUnlike combi boilers, which heat on demand, thermodynamic panels require large tanks to store heated water in, which can be quite tricky if space is at a premium.
    • Slow To HeatIt can take approximately 3-4 hours for the water to be heated sufficiently from when the unit is turned on. However once achieved, the optimal temperature is then maintained, for a constant supply of hot water.
    • Sometimes ExpensiveIn cases where a pump is needed, these hot water systems will require a small amount of electricity and will cost a household approximately €45-75 a year to run.
    • Short WarrantyWarranties usually only run up to 5 years so insurance is a must, given the large initial financial outlay.

    What Are Solar Thermal Panels?

    Solar thermal panels directly collect heat from the sun, working on the principle that black surfaces attract heat. Somewhat similar to a dark car, where the heat inside the car can far surpass the temperature outside upon significant exposure to sunlight.

    The heat generated in the solar “collector” panel is then transferred to a hot water cylinder. There are two types of these solar energy collector-type panels, evacuated tube solar panels, and flat plate panels. Evacuated tube solar panels are up to 20% more efficient than flat panels due to less heat loss and greater efficiency at collecting heat from the sun at different times of the day Flat plate thermal solar panels start from around €3,000 while the more efficient evacuated tube panels can be had for around €2,800.

    Pros of Thermal Solar Panels

    • No Electricity UseThermal solar panels use no electricity to run a compressor, unlike thermodynamic panels, and as such have much lower running costs.
    • Bill ReducingYour water heating bills could be reduced by 70%.
    • Long WarrantySome thermal solar panel suppliers provide warranties on parts and labour of up to 20 years.

    Cons of Thermal Solar Panels

    • InflexibleMust be installed on a south-facing roof.
    • Needs SpaceMuch like with thermodynamic panels you need space for the solar hot water cylinder.
    • Less Hot Water in WinterThermal solar panels provide much more hot water in summer than in winter.
    • Not Always EfficientNormally cannot meet 100% of a household’s hot water needs.

    How Much Do Solar Panels Cost in Ireland?

    With all their complex solar components, how much solar panels are will vary greatly depending on whether you buy them used, new with the installation, without installation, etc.

    We have divided the solar panel into the following three categories:

    We examine each one of these solar panel price categories in detail below.

    Are There Grants for Solar Panels in Ireland?

    There is plenty of help available if you’re looking to hop on the solar energy bandwagon. SEAI grants are available for PV panels and storage batteries, to the tune of €900 per 1KW panel, capped at €2,400. You can also offset some (around 13.5%) of the 23% VAT on your solar panels through your taxes over two years through the Home Renovation Incentive Scheme. If you are interested in thermal solar panels, the SEAI has a grant available for a value of €1,200.

    Selectra can help you double up your savings by getting better energy rates.

    What Is the Average Cost of Solar Panels in Ireland?

    The solar panels themselves come with different energy outputs; anywhere between 100w to 580w. The higher the energy output number is, the higher the cost is. On average a new solar panel can cost anywhere between €150 to €425.

    Determining which size panels, how many you need, and so on, is a process we recommend you differ to a renewable energy expert. They can take your home’s location, roof angle, and energy consumption to determine a system that would be best for your needs.

    Here are the latest for PV solar panels with the SEAI grant discounted from it:

    House Size Rated Capacity kWh per Year Cost After Grant CO2 Saved
    2-Bed Terraced 3.28 kW 2,856 kWh €4,237 994 kg

    How Many Solar Panels Do I Need in Ireland?

    The following factors are the main points you will need to consider when calculating how many solar panels you need for your home, business, or farm:

    • Roof orientation
    • Roof angle (in degrees)
    • Your current energy consumption
    • Historical weather patterns for your county

    It is important to remember that you don’t have to install enough solar panels to provide electricity for your entire home. Every little bit counts and installing a low-cost system, even just a single panel, will help reduce the cost of your electricity and still be there as a backup during power outages.

    If you are still interested in knowing how many panels you would need for your entire home, the Electric Ireland calculator is rather handy to get an estimate.

    Verdict: Are Solar Panels Worth It in Ireland?

    The of electricity and gas in Ireland continuously trend upwards year after year, decade after decade. Conservative estimates of savings for PV panels show €250 a year in energy savings, which means for a basic system (keeping in mind that basic systems may not net you a €250 annual saving) it would take 14 years to pay for itself.

    With savings ranging from 40% to 70% off annual energy requirements, solar energy in Ireland is becoming more and more popular. It is estimated that efficient solar PV systems could produce up to 80% of the energy needed for a household. however, this doesn’t necessarily translate to an 80% saving on electricity bills. There is no escaping standing charges and the PSO levy if you are connected up to the electricity network.

    If the goal of installing solar panels is to lower your energy bills, the easiest and fastest way is by making sure to switch energy providers every twelve months. Doing so can easily save you up to €825 a year according to the CRU. The table below breaks down the cheapest offers from Ireland’s largest providers.

    Once that is done, consider other energy efficiency measures for your home (such as improving insulation). Many home improvement projects can also benefit from grant support from the SEAI. On the other hand, if your motivations are mainly to help the environment and reduce your carbon footprint, you don’t need to install a full-on solar power energy system up-front. Start small and gradually add solar panels over time.

    You can combine this with other healthy energy habits like moving to a hybrid or electric car. If so, you may also want to consider a solar-power carport. Every little bit helps, and solar panels are a relatively easy way to cut your bills and help with the fight against climate change.

    Sunrun Customer Reviews

    To help you get a better idea of customer experience, we’ve included a sampling of Sunrun reviews below. Positive reviews mention the company’s quick and straightforward installation process and its friendly customer support staff. Critical reviews mention electricity not changing as intended or difficulty scheduling repairs and maintenance. We contacted Sunrun about these negative remarks and the cons listed in this review, but the company did not provide a comment.

    “I have been a longtime customer … Sunrun has met or exceeded my expectations for its products and services. The only thing I need to do is get a good backup generator or battery to run the house when the power is totally out at night. But I recommend Sunrun to about half a dozen friends and family that have [signed] up and they are very happy.” —Debbie B. via the BBB

    “The Sunrun team did a great job from start to finish. The installers were efficient and friendly. I learned a lot from them to add to my base understanding of solar. I very highly recommend SunRun to anybody. I was kept informed throughout the process.” —Bill Z. via the BBB

    “Hope you never have a problem with your solar panels. [It has] been about four months and was just told [it’s] going to be three more months before it will be fixed. The sales rep will not allow me to talk to her manager. This company [customer] service team is really bad about calling you back.” —Robert M. via the BBB

    “This company clearly indicated to us that by using its system we would enjoy a life virtually free of electricity costs from the public utility. While our cost did reduce, we still pay more [than] 2,000 annually to the utility. In addition, we pay Sunrun 2,240 annually for the use of the system! That works out to more [than] 4,200 for electricity! Sunrun has not lived up to its claims and cares almost nothing about us, unless we are late with the bill!” —Marc S. via the BBB

    The Bottom Line

    Not everyone has the resources to purchase a solar photovoltaic (PV) system up-front. Sunrun can make the process of going solar more cost-effective by offering solar loan and leasing options. A solar lease allows you to reap the benefits of renewable energy while not having to deal with other complications, like handling system maintenance and repairs. Plus, Sunrun provides rate-hike protection, a 10-year comprehensive warranty and access to high-quality solar panels. Despite Sunrun’s warranty being on the shorter end, it is comprehensive. Sunrun also includes maintenance and the unique perk of theft and damage protection for its solar power systems.
