Solar Panels
Solar PV systems are made up of several panels, with each panel generating around 355W of energy in strong sunlight. Typical domestic systems contain between 10 and 15 panels and generate direct current (DC) electricity.
Space is a key consideration. The average system size is around 4.2kWp and this will typically take up around 25m2 roof area.An unshaded, South facing roof is ideal for maximum electrical output. East or West facing roofs could still be considered, but North facing roofs are not recommended.
A system facing East or West will yield around 15-20% less energy than one facing directly South.
