How Solar Panels Work
On average, a solar PV system can save between €200-300 per year on your domestic electric bill.
Solar panels that produce electricity are known as photovoltaic (PV). These panels work by capturing the suns energy using photovoltaic cells. It’s these cells that convert sunlight into electricity.
PV panels don’t need direct sunlight to work. And they still produce electricity on cloudy days. Being Ireland, this is good news. Solar Panels also have a long shelf life. As the only moving part in a solar panel are the electrons, a panel will normally last about 20 years.

Hot Water from Solar Thermal Collectors
The SEAI now provides a Solar water heating grant of up to €1,200.
Solar panels that produce hot water are known as solar thermal collectors or solar hot water collectors. Solar Thermal is the use of solar energy to produce heat. Whereas Solar PV produces electricity.
The biggest impact that Solar Thermal can have on your home? Massively reduced heating bills. Solar Thermal can account for up to 60% of your hot water needs. Great if you have a large family or lead an active lifestyle and use lots of energy heating hot water for showers.
