Solar PV panels should ideally be sited on a south-facing roof at a 30°-40° angle
From an environmental point of view, photovoltaic (PV) systems seem instinctively attractive. By taking light (photons) and transforming it into electricity (volts) – hence the name – we can generate electricity from the sun’s rays. This method of electricity production is clean (in use) and displaces fossil fuels, reducing but not eliminating reliance on the grid. PV can in theory provide power anywhere, which is known as distributed or local generation.
Photovoltaic cells produce very small amounts of electricity so they are grouped together into modules. A panel consists of several modules linked together. Panels that are grouped are known as an array.
