This page about the different solar panels contains all the basic information you need to know about solar panels.
Solar panels are not all the same. In fact almost all solar panels are different.
All solar panels absorb sunlight and turn it into energy but the way solar panels absorb and transfer energy can be very different. The way solar panels work is determined by how the energy generated by the solar panels will be used. Energy produced by solar panels could be used to create electricity or heat water.
How solar energy is used influences how the solar panels should be designed.
Solar panels can collect energy in different ways and the design of solar panels is based on how the energy will be used. Basing the design of solar panels on how the energy created by solar panels will be used ensures that energy the sun’s energy is harnessed and transferred into usable energy with minimum loss.
Solar energy is usually gathered for creating electricity (solar electric) or heating water (solar water heating).
Photovoltaic solar panels turn sunlight into electricity. Electricity from photovoltaic solar panels can be used in the home or sold back to the national grid.
Solar panels for solar water heating absorb sunlight and use it to heat water as it is pumped round the solar panels. The heated water is used to heat water in the hot water tank to reduce the energy required to supply your taps with hot water.
