Solar photovoltaic (PV) panels generate electricity from the sun that can then be used to power household appliances and lighting. You can use solar PV systems for a building with a roof or wall that faces between South East and South West, as long as no other buildings or large trees overshadow it. Less energy will be generated if the photovoltaic surface is in a shadow for parts of the day but it will still generate electricity. more»
