Photovoltaic (PV) solar panels work by converting sunlight in to electricity. A group of PV cells can be grouped together to form a solar panel, also known as a solar module. When a group of solar panels are put together this is known as an array.
To ensure that your solar panels work well, they are placed in the right position to ensure that when sunlight hits the cells, as much as possible of it is absorbed by the semiconductor that is used to make the cell. This absorption of the energy "knocks" the electrons in the semiconductor free, allowing them to move freely. When this happens, an electric field in the PV cell forces these freed electrons to move in a given direction, what we all commonly refer to as a current. Solar cells have contacts that then draw off this electrical current.
The wattage a given cell or panel can produce is defined by the amount of current that can be drawn off, coupled with the cell's voltage.
The energy your solar panels produce is direct current which needs to be converted into alternating current for domestic use. This is done through the use of a solar inverter. The current then passes through to your consumer unit and joins up with your house's electrical system.
Whilst we obviosuly sell everything you need to self-install a solar array yourself, it is highly recommended that you use a qualified solar installation company. Why not get in touch with one right now?
