    The Indian government is working on becoming a serious player in the renewable energy game. By 2022, it hopes to achieve the target of 100 gigawatts in solar capacity.

    • As of March 2019, India had already installed 28 GW of solar capacity, four times more than the previous year. Source – IEEFA.org
    • By the end of 2019, India’s solar rooftop power generation capacity was 4375 mW, more than 70% compared to 2018. Source – Business Standard

    Why do residential societies need to ride the growing wave of renewable energy? We’d be lying if we said that lower light bills aren’t the main reason. Societies in Mumbai, Pune, Delhi and Bangalore have successfully reduced their light bills by 65-70% after installing solar panels on the rooftops, saving lakhs in electrical bills annually.

    At a community and national level, every society that adopts renewable energy alternatives helps reduce global negative environmental impact.

    What is a solar panel?

    Technically made of smaller photo-voltaic cell units, solar panels generate Direct Current (DC) by allowing ‘photons’ or the light from the sun to separate electrons from atoms. The solar inverter takes the electricity from the solar panels and converts them into Alternating Current (AC) electricity which is supplied inside the households through power grids.

    Types of solar panels for residential buildings

    There are two main types of PVs currently in use:

    Monocrystalline

    These are made of single-crystal of pure silicon, thereby allowing more room for the electrons to generate more electricity from the light of the sun.

    Polycrystalline

    Fragmented silicon slabs (not pure silicon) are melted together to form wafer panels. These are also known as multi-crystalline solar panels.

    Difference between mono and poly panels

    Monocrystalline Polycrystalline
    Black in color Energy efficiency is 17-20%High priceWorks with low sunlight Blue in colorEnergy efficiency is 12-15%Low priceGives less output in cloudy weather

    Concentrated PV panels (CPV)

    Available in low, medium and high concentrations, CPVs are considered the future of solar energy with curved mirror surfaces and lenses placed strategically and are recommended to be integrated into the building at the design stage. Even a low concentration CPV panel can produce 2x more energy than regular PV panels whereas multi-junction HCPV is known to be 40% or more efficient.

    Installation and cost

    Equipment needed for installation are solar panel modules, mounting/racking system, electrical wiring to connect with the general power system, solar inverter, (charge controller and lead battery for off-grid systems).

    Grid-tied vs off-grid solar systems

    On-grid systems are connected to the local power grid and have a lower installation and maintenance cost. If your system produces more energy than you use, the surplus is fed into the main system and turned into credit which you can cash out. A net metering system is installed to track usage which eliminates the need for battery storage or back-up. But the supply is disconnected during power outages.

    An off-grid system is self-sustaining and independently installed from the main supply and uses batteries for power storage. They are perfect for places with lack of electricity grid or inconsistent supply. Maintenance is required for the generator and battery, not so much for the panels.

    Depending on the type of solar system (off-grid or on-grid), sq feet and generated watts, will vary from one manufacturer to another.

    Off-grid system for an apartment complex approximation

    On an average, an off-grid system installation would cost Rs 800,000 to Rs 1,60,000 lakh including batteries (1-2 KW). However, the government provides a 30% subsidy for residential rooftop solar panel installation. Additionally, there is 80% accelerated depreciation offered by the rules of the Income Tax Act. However, if more kW are required, the price can go up. For instance, a 10 KW system can cost up to Rs 7,00,000. However, an on-grid 10KW system can cost around Rs 4,50,000 which means that the lowest 1KW can cost between Rs 65,000 to Rs 75,000 depending on types of panel and inverters.

    Frequently Asked Questions

    1) What’s the warranty period of solar panels?

    Minimum 15 to a maximum of 25 years. Installation warranty is 2-5 years.

    2) Should I use Thin Film solar panels for my apartment building?

    These are less expensive but short-lived and space-consuming, thus generally not recommended for residential buildings.

    3) What certifications should I be aware of?

    Solar panels should be approved by MNRE (Ministry of New and Renewable Energy), and fulfil requirements of IEC 61215/ IS 14286 and IEC 61730 Part I.

    4) Which are the types of solar inverters?

    String inverters are the most commonly used residential solar inverters. However, microinverters power optimisers are also gaining traction.

    5) What’s a Smart solar inverter?

    They have algorithms for real-time monitoring through an app, usage pattern detection and predictive data insights on demand and supply.

    6) What are the rooftop requirements for solar system installation?

    Best positioning for maximum sunlight is facing south. The roof should be repaired if damaged and be sturdy enough to bear the load. According to the government, a grid-tied 1 kW rooftop system requires 10 sq metres of shadow-free area. Click here for government requirements for grid-connected rooftop systems.

    7) How do I apply for a grid-connected rooftop solar system?

    You can make an online application at https://solarrooftop.gov.in/ for Delhi and www.mahaurja.com for Mumbai. Other states also welcome online applications.

    8) How do I select the vendor to get Central Financial Assistance?

    According to the government, the beneficiary should select a valid selected vendor of the State Nodal Agency through bidding, empanelment, rate contract against MNRE sanctioned capacity.

    It’s imperative that you conduct enough research on configuring the type of solar system you wish to install by comparing prices, services and overall cost-effectiveness offered by private manufacturers providing off-grid services as opposed to grid-connected rooftop systems.

    Is my House Suitable for Solar? What we look for when checking a home’s solar suitability in Ireland

    That’s a question we get a lot and would be only too happy to help you with.

    We look at a lot of factors when deciding if a house is suitable for PV solar panels. One of our most important jobs is to help a homeowner decide if solar is a good idea in the first place.

    For a lot of homes in Ireland solar is a great addition, but we do (and have) recommended people against fitting solar where we think it would not be a good investment for their or the environment.

    There are 5 main factors to consider when deciding if your home is suitable for solar:

    Let us do the hard work

    The below is just in case its of interest for you. We are more than happy to check the suitability of your home for solar for you, that’s our job. Its quick, and its free. If you’d like numbers for your own home, including costs and predicted electricity generation numbers, just fill in the solar PV quote form and we’d be glad to help.

    Roof Type

    Pitched roof types

    Solar panels can be fitted on just about any roof type. They work very well with all the main roof types here in Ireland.

    Flat concrete tiles, fibre cement slate, pan tile / roman tile / wavy tile and natural slate are the most common types here in Ireland and solar panels can be fitted to any of those. Natural slate takes a little longer than the others, and so the installation process might take half a day longer.

    Flat roof types

    Solar panels can be fitted to just about any type of flat roof without compromising it’s water tightness. In this case, a frame is added to tilt the panels up to face the sun.

    Roof Direction

    If you have a flat roof then we can point the your solar panels any direction, which normally will be south.

    If you have a pitched roof though the direction the panels will face depends on which direction your roof is already pointing (as you cannot put frames onto pitched roofs to point the panels in a different direction).

    Due South: most power output

    A south facing roof will produce the most electricity. Being a bit off directly south though has minimal impact on production. Anywhere between south-east and south-west will be very similar.

    South East / South West: 5% Lower

    If your roof faces south-east, or south-west, then your production will be a little lower. The timing of your electricity production will change too. South east produces more in the morning, and south west more in the afternoon / evening.

    integrated, solar, rooftop, gazebo, solutions, residential

    East / West: 20% Lower, but more useful?

    If your roof faces due east, or due west, the production will be about 20% lower than a south facing roof.

    The production numbers though are still very good and make a savvy financial investment. There’s a side benefit to east / west facing solar arrays, as they produce the most electricity when you need it most.

    Most homes use their largest amount of electricity in the morning (when east facing panels are producing), and late/afternoon evening (when west facing panels are producing), as people turn on their kettles, showers and ovens.

    There’s a good argument for east / west facing arrays as it means less need for battery storage as you can use the power directly. You could also cover both sides of your roof as both are pointing in a useful direction.

    Northerly: not worthwhile in Ireland

    As you move to pointing north the production from solar panels rapidly drops off, and we would not recommend it as a good financial or carbon-footprint reducing investment.

    Azimuth, the technical term for direction

    In solar calculation reports you’ll see the term azimuth, normally quoted in degrees. That’s just the fancy term for which direction the panels will be facing.

    Is my roof big enough for solar?

    Very likely is the short answer. Most Irish houses have ample space on their rooves to make electric solar panels worthwhile.

    For example, a typical 2 bed mid-terrace house might have enough space to fit a 3kW solar panel array on it’s roof, which is big enough to produce almost half the electricity that family might use in the year.

    Here’s a ball park guide to the amount of power that common roof areas would produce:

    Solar Panel Area System Size (in kW) Approx Annual Units generated in Ireland (if facing south)
    10m 2 2.1kWp 1806kWh
    15m 2 typical 2 bed mid terrace 3.15kWp 2709kWh
    20m 2 typical 3 bed semi-detached 4.2kWp 3612kWh
    25m 2 typical 4 bed stand alone 5.25kWp 4515kWh
    30m 2 6.3kWp 5418kWh

    The above numbers are the area covered in panels. Due to planning permission rules here in Ireland you cannot fill the whole face of the roof. You need to leave a margin free from panels:

    • Top of roof (by the ridgeline): 0.25m left free
    • Bottom of roof: 0.5m left free
    • Sides of roof: 0.5m left free if end of roof, no free space required if mid-terrace.

    If you are doing your own back-of-envelope numbers do keep in mind your roof is on an angle, so it has more area that a flat roof would. A typical home in Ireland has a 30° slope on it’s roof, so giving you 15% more area to fill with solar panels than a flat roof on the same building.

    My roof has lots of angles

    It would depend in that case. Lots of small triangles can be difficult, as solar panels are rectangular. Often though it can be fine with a bit of planning in both solar panel positioning and inverter design.

    Unsure about your roof and solar? Just ask.

    If you are not sure if your roof would be suitable please do feel free to fill in our solar panel quote form. We can quickly have a look at your roof on google maps and let you know what might be possible. It’s quick and entirely free. We would give you quick quote including guide numbers to both costs and projects solar generation figures to help you decide if solar PV is the right choice for your home.

    Shading Solar Panels

    Shading can be an issue, and should be taken into account before deciding is solar is a good idea, both for your and for the environment.

    Neighbouring buildings and trees

    If your roof spends a lot of time in direct shadow then solar might not be the best choice. A bit of shadow early or late in the day is not really an issue, but direct shadow for significant parts of the middle of the day would be.

    You do not need to be able to see the horizon from your roof. As long as you can see most of the sky it is normally fine.

    If it helps, the sun hits a bit over 60° in the sky during mid summer in Ireland, whereas mid winter it’s nearer 15° on the shortest day.

    Chimneys and dormer Windows

    One item creating a shadow tracking across your panels is not usually an issue. With a bit of planning in how the panels are wired up and inverter planning then we can mitigate for such.

    If your roof has many items causing lots of shadows that can affect the production. Let’s say you’ve a large chimney breast in the middle of your roof plus two dormer Windows, with just small gaps in between. In that case its possible that the gaps are in shadow too much of the time to be worth putting panels in there.

    Really though, to know for sure we’d need to take a quick look. The direction your roof faces is another important factor in looking at shadows.

    Unsure about shading on your house? Just ask.

    Again if you are unsure please don’t hesitate to ask. We can have a quick look to see if shading would be an issue or not for you. We can see a lot just from google maps, and also we have drones so we can check for shading issues from a roof-height perspective. Just get in touch if you’d like to chat more on this.

    We will always be straight on this. If we think solar would not make economic sense for you due to solar, we wil always tell you that.

    Electrics

    When our engineers do the site inspection before giving you your finalised quote, they will check your fuse board and electrics. This is required, as well as being a very good idea too!

    Modern fuse boards very rarely need any work. The only issues we see are on particularly old electrics and it’s usually around missing earth bonding or another issue with the earth.

    If we see any problems like that, we’ll let you know and it might be something you have to get rectified before solar panels can be added to your home.

    This is only a good thing for your home though. It is highlighting places where safety has fallen behind modern standards and usually the improvements are relatively easy to do.

    Hot water

    A solar immersion diverter is an optional extra that takes an spare power not required by your house and uses it to heat your water tank via your immersion element.

    If you would like that you need to have a hot water tank that has an immersion element in it. You do not need to have a separate, extra immersion element just for solar. The one element can be used by solar and you can turn it on manually just like before whenever you like too.

    If you have a hot water tank that does not have an immersion element, you can add a device called a Willis heater. Effectively this adds a immersion heater outside your tank that circulates the hot water into your tank. very clever!

    They are relatively cheap, and you’d need a plumber to install it before we wire it up. Just get in touch if you’d like to know more about them.

    A better use of spare power?

    There is no need to feel compelled to add an immersion diverter to save wasting power any more. From 2022 you get paid for any unused electricity your panels generate that gets sent back to the grid, which is a great use of spare electricity you make.

    Grant

    Your house will almost definitely be eligible for the SEAI Solar Electricity grant as long as:

    • You have a connection to the grid
    • It was build an occupied by 31st Dec 2020
    • This grant has not been claimed before on that property

    They are the main requirements that depend on your property, though you can see our page about SEAI grants for solar for more info, or see the SEAI’s Website.

    Rent My Roof For Solar | YSG Solar

    If you’ve got property with vacant roof space then renting your roof for solar is a great way to make some extra money. Of course, most residential property owners will be better suited to a traditional rooftop solar installation, but for owners of larger properties, and commercial properties, renting the roof for solar could be the way to go. The first step to renting your rooftop for solar is finding an established, experienced solar developer to handle the project. So, if you do have some empty roof space going to waste, reach out to YSG Solar today and learn how much you could earn by renting your roof for solar.

    How Does Renting Your Roof For Solar Work?

    Space for large solar arrays is in high demand at the moment, and will likely remain in high demand as the energy sector pivots towards renewable energy sources moving forward into 2020 and beyond. With this in mind, it’s no surprise that solar developers are eager to find suitable roof space to install solar panels. When you rent your roof for solar, an energy developer will pay you an annual fixed-rate rent for permission to generate solar energy on your rooftop. All you need is some spare roof space.

    What’s more, the solar developer will take on all responsibility for the project, alleviating you of any pressures around financing, costs, operations, maintenance or anything else. The developer takes charge of project development, you just need to provide the roof space. On top of this, you will receive a portion of the profits generated by the solar array sitting on your roof.

    What If I Sell The Property?

    If you decide to sell the property during the solar lease term, that’s totally fine. It’s simply a matter of transferring the solar lease agreement to the new property owner, much like any other typical lease arrangement. Indeed, your property may even become more attractive to prospective buyers as a result of the solar lease. The idea of acquiring a new property which is already generating consistent revenue could be a real draw for those looking to buy.

    Could My Roof Be Damaged During Installation?

    No, your roof will be safe in the hands of experienced solar contractors. In fact, if you have a flat roof, it may even be possible to install the solar panels without penetrating the roof at all. This is achieved by using a ballasted mounting system for the solar array. Ballasted mounting means that the solar equipment is weighed down to hold it in place, rather than penetrating the roof to secure the panels. Either way, your roof will be examined ahead of installation to ensure that it is suitable for the project before any work occurs.

    Above all, if you’re interested in renting your roof for solar you should do your research, speak to a reputable solar developer. and be certain that you want to enter a solar roof lease. Renting your roof for solar is a long-term investment and if you go about it the right way, you could be seeing the rewards of your solar roof lease for years to come.

    If you’re interested in renting your roof for solar panels, contact YSG Solar today. We take care of the whole process from start to finish so you can start earning extra income right away.
