    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
    “>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
    “>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.

    Is a 10kW solar system right for your home?

    As the cost of solar continues to get cheaper, more people are choosing to install larger solar system sizes. This has led to 10 kilowatt (kW) solar systems becoming an increasingly popular solar solution for large homes and small offices.

    A 10kW solar system is still a significant investment and you might not even need that much power! In this article, we take a closer look to see if a 10kW solar system is the right size for you.

    How much does an average 10kW solar system cost?

    As of January 2023, a 10kW solar energy system will cost about 30,000 before incentives, based on the average cost of solar in the U.S. When you take the federal tax credit into account, that price drops to about 21,000.

    It’s important to keep in mind that solar system pricing varies from state to state. In some areas, additional state or utility-based solar rebates may reduce the installation cost even more.

    The following table outlines the average cost of a 10kW solar system in different states, so you can get an idea of how much solar could cost in your area.

    California 26,800 18,760
    Florida 26,100 18,270
    Texas 27,700 19,390
    North Carolina 24,900 17,430
    Arizona 26,700 18,690
    New Jersey 27,800 19,460
    Massachusetts 28,700 20,090
    Georgia 23,300 16,310
    New York 28,600 20,020

    Find out how much a 10kW solar system costs in your area

    How much electricity does a 10kW solar system produce?

    A 10kW solar system can produce between 11,000 kilowatt-hours (kWh) to 15,000 kWh of electricity per year.

    How much power a 10kW system will actually produce varies, depending on where you live. Solar panels in sunnier states, like New Mexico, will produce more electricity than solar panels in states with less sunlight, like Massachusetts.

    Can a 10kW solar system power a home?

    Yes, a 10kW solar panel system will cover the average American household’s energy usage of about 10,715 kWh of electricity per year.

    However, your home’s energy needs could be quite different than the average American household. In fact, energy consumption varies a lot between states. Homes in Wyoming and Louisiana, for instance, tend to use more electricity than homes in other states. So while a 10kW solar array might be perfect for a home in Louisiana, it might be too big for a home in a state like New York, which uses much less electricity on average.

    10kW solar systems do produce enough electricity that you could go off-grid. The only thing is you would also have to install solar battery storage to store the excess electricity a 10kW off-grid solar system produces.

    How much can you save on your electric bill with a 10kW solar power system?

    Based on the average electric rate and usage in the U.S., the average homeowner can save around 125 per month with a solar system that’s designed to cover all of their energy consumption. That’s about 1,500 per year in solar savings!

    In almost all scenarios, a solar panel system will significantly lower your utility bill. How much a solar system will actually save you can vary widely from state to state. This is because your electric bill depends on:

    • How much energy your panels produce
    • How much electricity costs
    • The net metering policy in your state

    For example, a 10kW solar system that generates 1,000 kWh in a month in Florida would save you about 110 on your monthly electric bill. If a system installed in Massachusetts produced the same amount of solar energy. 1,000- kWh. it would save you 190 a month on your power bill.

    The difference in savings is due to the fact that electricity is substantially more expensive in Massachusetts than it is in Florida.

    How long does it take for a 10kW solar system to pay for itself?

    The average payback period for a 10kW system can be anywhere from 8 years to 20 years, depending on where you live.

    Your location impacts how much your system costs, how much electricity the system produces, and how much the system will save you. all factors which influence the payback period.

    Your return on investment could be even better if you live in an area with additional solar rebates like solar renewable energy credits (SRECs).

    How many solar panels make up a 10kW solar system?

    A 10kW rooftop solar system will need between 25 and 27 solar panels. The actual number of solar panels it takes to make a 10kW solar PV system depends on the wattage of the solar panels.

    For example, if you install 300-watt solar panels, you’ll need 34 panels to make a 10kW system. If you use panels with a higher power rating, like 400-watt panels, you’ll only need 25 panels to reach 10kW in size.

    This is a lot of solar panels, so you’re going to need a lot of roof space in order to install a 10kW system.

    Use our solar panel drawing tool to see how many panels you can fit on your roof

    How much roof space do you need for a 10kW solar system?

    A 10kW solar installation will usually require between 440 and 475 square feet of roof space.

    The actual square footage you need depends on the wattage of the panels you install. The lower the wattage, the more panels you need, which increases the amount of roof space you need.

    Ideally, you would want at least 475 square feet of south-facing roof space to install your panels, as this maximizes the amount of energy the panels will produce.

    Can you install your own 10kW solar system?

    Yes, you can buy DIY solar kits to install a 10kW solar panel array on your own.

    10kW solar DIY kits often sell for between 14,000 and 24,000, which is slightly cheaper than the installed price you would get with a solar company. However, DIY solar can be dangerous if you don’t know what you’re doing.

    Plus, creating the right system design, including the location of the panels and which solar inverter to choose can be quite challenging. Sometimes, installing panels yourself can even void the warranty on the panels.

    You’ll oftentimes need the help of a solar industry professional or a licensed electrician in order to properly install a DIY system and pass inspections, which can actually cause you to spend more money than if you had just gone with an installer in the first place.

    Finding the right installer for a 10kW solar system

    To find the best installer for your 10kW solar system, you should get multiple quotes from different solar companies. You can then do a solar quote comparison, which will help you get the best price for installing solar panels on your roof.

    Start with local installers with licensed contractors in your area, as they can give you personalized service, and they typically have a good understanding of what incentives are available in your area.

    We make it easy for you to find the best local solar companies and certified contractors in your area, thanks to hundreds of customer reviews and our state-of-the-art solar calculator.

    Fantastic 20kw off-grid solar system for chicken house. InkPV

    Hello, in today’s case study, we bring you the 20kw off-grid solar system for a chicken house in the Philippines. This case study is a typical case for agriculture.

    The chicken house is on a small island of the Philippines, where the city grid cannot cover. In the old time, there are only diesel power generation systems on the island.

    Fantastic 20kw off-grid solar system for chicken house

    The chicken house owner June Pluto, decides to buy an off-grid solar system from China for below reason

    Diesel oil is getting more and more expensive

    The price of diesel is on the verge of increasing day by day. The overflowing of diesel have brought many changes, especially in the backward areas where people use diesel generators.

    The financial crisis and the energy crisis have already affected the living conditions of people in backward areas badly.

    Every nation in the world is going through some bad energy crises. The supply and demand chains for Diesel and other oils are vastly different, prompting people to consider what they should do next.

    June Pluto knows this situation. In fact, he knows if he doesn’t step forward and buy an off-grid solar system from China, he is going to regret it a lot.

    Solar system technology grows fast

    Despite all of the facts and people’s fears about financial crises around the world, there is hope in the form of the solar system. A solar system is one of the most sustainable and reliable ways to produce energy that will meet all your energy needs.

    Solar systems are now getting popular, especially during the cool summer months when people realize while sitting at home that they need them more than anything else.

    Not only that, the technology of the solar system is now getting more advanced and safer in many aspects.

    All it requires is a one-time investment, and afterwards you don’t even need to do anything, absolutely nothing, and the energy will come directly from sunlight and then in the form of current that will complete your daily life work.

    What appliance in the chicken house?

    There are lights, hatchery machines, exhaust fans, a water pump in the chicken house. It’s important for keeping stable temperature in the chicken house, that’s why they need a reliable source of power.

    His diesel generator is 20kw, that’s why he wants to buy another 20kw off-grid solar system.

    How many batteries for the 20kw off-grid solar system ?

    There are 16pcs and 32pcs battery options in the 20kw system. As the shipping freight is high and the system battery is expected working 8 years, June Pluto chooses the 32pcs option.

    Because every battery bank DOD is related to the capacity, 32pcs working time is twice than 16pcs option.

    kw off-grid solar system design

    Here share with you the connection drawing for his 20kw off-grid solar system.

    kw off grid solar system cost

    The price is 18,141, total volume:7.4CBM, weight:3327KG price term:EXW Foshan, Guangdong. China.

    His forwarder pick up Foshan, with his new house furniture. Put all the stuff in 20GP, and ship to Manila.

    And we issued FE for the off-grid system, and June Pluto no need to pay the customs tariff in port of discharge.

    How much electricity will the 20kw off-grid solar system produce?

    The solar panels power is 20kw, and the 20kw off-grid solar system produce 80kwh each day, and the life span of solar panels is more than 25years. This is a sustainable system can be used for many years.

    What does he think of the20kw off-grid solar system ?

    It brings his stable power

    One of the biggest problems for June Pluto was stable energy. He really wanted something that provided stable energy 24/7.

    Because the diesel generator requires a lot of maintenance, it can only be used for 24 hours at a time.

    Pluto has had it for 24 hours after the solar system gained stable power in June.In daylight, he gets the electricity directly from the sunlight, and after sunset, the batteries, which have already been charged all day, provide the power at night. It couldn’t get more great for June Pluto.

    No noise, no pollution.

    June Pluto felt at peace for the first time in a long time. The diesel generator sound is so irritating.

    The worst part is that no one gets used to its sound, which causes a lot of mental tension; the same thing happens with June Pluto. Fortunately, after installing the solar system, there is no noise or pollution at his place.

    The way he told us, whenever he gets up in the morning for work, the only thing that gives him relief is that he will no longer hear any of the rusty diesel generator sound and the smell and pollution in his area.

    There is no need for additional costs because this is a one-time investment.

    No extra fee

    Installing a solar system is a one-time investment. Unlike generators or the electricity grid, where you must pay for diesel and electricity bills on a daily and monthly basis, there is no such maintenance in a solar system.

    When you install the solar system, that is it; you will never spend a penny afterwards on it. It will give you stable power during the day courtesy of the sunlight, and then at night you can use the batteries, which will already be charged from the solar system.

    You don’t have to do anything for the solar system’s processes; in fact, you wouldn’t know whether the power comes from the sun or the batteries.

    The Price of a 20kW Solar System for Commercial Solar Projects

    A 20kW solar system has now become a standard-sized solar system for small to medium-sized businesses looking to reduce their operating costs by powering their daytime electricity consumption from solar power.

    Uptake of commercial solar installations in Australia has grown rapidly over the last two years thanks to a significant government rebate of approximately 12,000 on a 20kW system, and because the cost of solar power is now significantly cheaper than buying power from the grid for the vast majority of Australian businesses.

    This article will provide a brief overview of the price of a 20kW solar system, potential power yields (in kWh), and financial returns that a business may expect.

    The Price of a 20kW Solar System

    The price of a fully installed 20kW system has fallen dramatically in recent years. The wholesale price of photovoltaic panels continues to be driven down by market conditions, in particular by the growth of solar in developing markets such as India and China.

    A 20kW solar system is now less 1/4 of the price it was in 2008. This significant drop in initial outlay allows many businesses to see a return on their investment in well under 5 years, making it an attractive option even if you are leasing your premises.

    As a rough guide, the price of a fully installed 20kW commercial solar system starts at around 16,000 – 18,000 and can save you up to around 8,000 a year on your power bills depending on the price you pay for your electricity and how much solar power you are able to use at the time it is generated.

    Most businesses will then choose to upgrade their system to high-efficiency panels and to include the latest inverter and monitoring technology. This can increase both the price and the performance of the system. An absolute top-of-the-range system will be in the ballpark of 30,000-35,000 depending on the site.

    Finding the right system for your needs will typically involve a discovery call with one of our representatives, who can run through the pros and cons of the different options.

    There are a number of factors that need to be considered when installing a commercial solar system, hence installation costs can vary considerably. Solaray offers a full installation service, which means we will typically take care of council approval and an engineering certificate. Not all solar installers offer this level of service, however, it is a critical part of the process that ensures a safe installation, and it can also absolve board members of liability in the event of any issue with the roof over the life of the system.

    Installation costs can also vary, for example, a shed or barn roof will have very few if any additional installation costs, whereas an apartment building or a ground-mounted array may have additional costs such as long cable runs, crane hire, and site preparation such as clearing trees and laying foundations.

    Please contact the Solaray Commercial Team for more information. We can provide a full quotation with independent analyses and reports that are accepted and trusted by banks. We can also provide figures for commercial leasing arrangements with 0 money down, and immediate savings from your power bill. A commercial solar power system will often be cash flow positive from day one.

    kW Solar System Details

    Panels: 48 x 415W panels, for example.

    Inverter: The choice of the inverter will depend on a number of different factors. Often we will install 2 x 10kW inverters to maximise reliability and flexibility with panel design. We only provide the leading models from the largest manufacturers including Enphase, SolarEdge, SMA and Fronius.

    Mounting Kit: Solaray can design a mounting solution for most roof types. The two main exclusions are asbestos and slate roofs. For a flat concrete roof please contact us as this will typically require additional work such as waterproofing.

    20kW Solar System Output in Sydney

    As a general rule, a 20kW solar power system will output around 80 kWh a day averaged out across the year as illustrated in the image on the right. As illustrated, the system will output more power during the summer half of the year and less in winter. There are a number of factors that influence this figure and these include:

    – The location of the system and the expected daily and annual solar irradiation and Cloud cover

    – The orientation of the roof and the tilt angle of the solar panel array

    – Whether there is any shade cast on the panels. For a roof with patchy shade, we recommend SolarEdge or Enphase for panel-level optimisation

    – Operating temperature of the panels – it is important to use good quality panels that perform well on hot summer days.

    – Whether the solar panel capacity is professionally matched to the inverter’s capacity. This is an important design consideration and our commercial team can discuss this with you in more detail.

    – The quality of the individual components. For example, a panel from LG Solar may outperform a cheaper Chinese Made panel by 5% or more. This can result in further savings off your power bill, especially when extrapolated out over a year… or a decade.

    A 20kW system installed in Sydney with no shade orientated north can generate up to and over 100 kWh on a sunny day in summer. In winter, when the days are shorter and the sun is lower in the sky, a 20kW system may only produce 60 kWh a day.

    When you make an enquiry, our commercial solar team will ask you for a number of power bills to analyse when your business uses its power (both across the day and across the year) to accurately size up a solar power solution.

    Financial Benefit of a 20kW Solar System in Sydney

    A commercial solar power system in Sydney directly reduces your power bills by feeding solar power directly into the main phase of your power supply. Because of this, the potential savings of a solar system depend on how much you pay for your electricity, when you use your power and how much power you use at any one time.

    As a rough guide, a 20kW solar system can save you up to approximately 8,000 (this figure will change depending on the price you pay for electricity). For more information please contact our commercial solar team.

    With a possible return on investment now well under 5 years, a 20kW solar power solution is an attractive investment option for your business to reduce short to medium-term operating costs and improve the environmental profile of your business.
