How Solar Works

Solar power works on a relatively simple principle. When photons from the sun hits the silicon cell in a solar panel, most of the light bounces off. Some of it, however, penetrates the reflective surface and blast electrons off their atoms which collect up one end of the panel, creating current.

• That current (DC) needs to run through an inverter to change it to AC so it can be used in the building.
• Power can then be exported back to the grid, earning you a return on your power generation.
• In the case of a gross feed-in tariff, you are paid a premium for ever kilowatt hour you generate, as opposed to a net feed-in tariff whereby you are only credited for the power you generate and do not use.
• When people talk about the efficiency of your solar panels, what they mean is the amount of light which bounces off as opposed to soaking in and turning into electricity.
• Cheaper panels are made from amorphous silicon which doesn’t convert light into power very well. For the money you spend you may as well throw a rug over your roof and hook it up to jumper cables.
• Yes Solar only stock monocrystalline modules, which are the best panels currently available and do not compromise on quality.
