Everything you need to know about placing solar panels on your roof

Analysis: You can expect a simple system of six to eight solar panels to generate about a third of your home’s electricity needs

proverbGive a man a fish and you feed him for a day; Teach him to fish and you feed him for life“It has an unlikely echo in The current fossil fuel crisisespecially when it comes to more measures than is needed to help homeowners deal with it High electricity costs. While giving someone a discount or a discount on their energy bill will help them once, giving them the ability to generate their own electricity will last their life. This is where Ireland’s unlikely source of electricity, in the form of sunlight, can be a lifeline for many families struggling to pay their energy bills.

Ireland is better known for its wind and waves than sunlight, but advances in solar technology and cost reductions now make it an attractive option for residential electricity generation in Ireland. The solar panels that produce electricity are known as Photovoltaic solar modules. These panels generate electricity when exposed to light and have been one of the fastest growing power generation technologies worldwide.

From RTÉ News, a new study finds that solar panels can provide 25% of Ireland’s electricity needs

The systems produce electricity that can be used to power your household appliances and heat water through immersion. The homeowner will not notice any difference in how the appliances work and there is no need to notify or change your electricity supplier.

Of course, solar systems need sunlight to function but most will still work on cloudy days in Ireland albeit not at full capacity. You can expect a simple system of six to eight panels on your roof to generate about a third of your annual electricity needs, mostly between May and September. This means that you will still be dependent on your electricity provider, especially in the winter and darker months, but you will generally buy less electricity from them.

Solar PV systems are sized in technical units called kilowatts (kW) and a simple 2.4kW system will contain about six to eight panels. Most small systems of this size do not require planning permission, but you should check with your local authority because the rules vary from location to location.

From Morning Ireland of RTÉ Radio 1, Dr Paul Dean talks about how more than a million Irish homes have roofs suitable for solar panels.

While the fuel in the form of sunlight is free, installing the panels is not and will cost around 4,000 euros for a simple six to eight panel system. [2.4kW]. there government aid Available to help reduce costs, bringing the total price down to around €3,000. These are ballpark costs and will vary from supplier to supplier. If you are interested in acquiring solar panels, it is very important to shop for several quotes and use a reputable certified installer.

A typical home with six to eight solar panels on the roof can save around 400 euros a year in electricity bills, with the system paying for itself in seven to ten years. The deployment of residential solar PV in Ireland addresses key energy and climate issues such as affordability, but is also helping Ireland nationally in terms of increasing Securing supply and reducing pollution from greenhouse gas emissions.

In Union Carbide Corporation, we have carried out a studyfunded by Irish Solar Society, to understand how many homes can use sunlight to generate electricity. We were surprised to find that about half of homes in Ireland have potential for this technology, and if all of this is achieved, we can produce enough electricity to meet a quarter of residential electricity demand.

From RTÉ Radio 1’s Today With Claire Byrne, will solar panels work in your home?

But there are very real challenges in rolling out this technology on a national scale. For a start, there is a shortage of skilled workers to do the work. Furthermore, while the technology’s economic and environmental arguments are very compelling, it still requires a significant upfront investment by the homeowner.

In this regard her SEAI set of grants Available to homeowners Cut costs, but many families will still find the investment prohibitive. This is where government policy needs to step in and offer 100% grants to finance solar panels for homes receiving fuel allowance because low-income families need the highest level of financial protection during this crisis.

To get the best out of your plates, you will also have to change some behaviors related to the use of appliances such as dishwashers and washing machines. If you have a solar system, it is better to turn on these devices when the sun is shining

While some homeowners are looking to put in a battery system to store any excess electricity, this increases costs. However, if you have a hot or submerged water tank, you can set up your solar system to convert excess electricity to heat the water. In essence, this works like a battery and stores the electricity as hot water, which can be used to offset the immersion use of hot water showers etc.

Any remaining electricity can be exported to the grid and homeowners can now get paid small fee For this. but with The current electricity price hikeIt is best to use as much electricity generated from solar energy in your home as possible.
