Solar panel. Solar panels absorb the sunlight as a source of energy to generate electricity or heat. A photovoltaic (PV) module is a packaged, connect assembly of typically 6x10 photovoltaic solar cells.
Just how much electricity you will generate through solar panels depends on four key factors: the size of the solar panel system, the direction and angle of your roof, the level of shading your roof has and the time of year. Typical domestic solar panel systems range from 2kw to 4kw.
