Solar Photovoltaics (PV) captures and traps the sun's energy (known as Direct current or DC) using photovoltaic cells. These cells are made from multiple layers of semi-conducting material, usually silicon. When light shines on the cell this generates an electric potential across the silicon layers, which allows a current to flow, producing electricity. The stronger the sunshine, the more electricity is produced.
These cells don't just need direct sunlight to work as they can still produce optimum amounts of electricity even on a cloudy day.
The electricity produced by the solar panels is then converted into electricity that can be used within a building. This is carried out by an inverter, which converts the DC electricity generated by the panels in to AC (Alternating Current), which is what your domestic appliances use. During daylight hours the energy from the solar panels can be used to supply your building appliances, replacing electricity you would otherwise purchase from your supplier.
Under the Feed In Tariff scheme you are paid for all electricity you produce regardless of whether you use it or not at a rate of 14.90 pence per kWh, with an additional 4.64p for 50% of what is produced, with your electricity company assuming that electricity is exported to the national grid.
To get the most out of the electricity that your panels produce, it's best to use appliances like dishwashers and washing machines during the day to take advantage of the free electricity generated.
Types of Solar PV Panels:
Solar Panels transform daylight into electricity, which homeowners can then turn in to earnings and energy savings thanks to Feed-In Tariffs (FITs).
The sun's energy is absorbed by solar cells in photovoltaic (PV) panels before being converted into electricity. This can then be used in the home or fed back into the national grid.
Daylight causes an electric field across layers of silicon in the cells, creating an electric current. Within seconds of reaching the earth's surface, photons from the sun energise electrons in the silicon which can then power devices in homes across the country.
Domestic Solar panel systems are connected to the national grid so that any extra electricity that hasn't been used in the home created by a Solar power can be used by other homes. A fee is paid by the electricity company for every kWh generated by the solar panels, regardless of whether you use it, or it is exported to the national grid.
Your home will also be fitted with a monitoring device to keep track of the total amount of electricity generated by your PV panel Solar system.
Solar panels do not need direct sunlight to function and even on a cloudy day will generate electricity. And so as the daylight hours pass, your earnings will increase.
