Solar Photovoltaic technology uses the power of the sun year round to generate electricity.
This electricity can be used on site or at times when it is not needed, and sold back to the national grid. Modules are mounted on a roof in a southerly direction and where there is no (or limited) shading. The electricity conversion process causes no waste and no emissions and is subject to subsidy under the current Feed in Tariff (FiT) scheme.
The solar PV package usually includes the panels, roof mountings, inverter, AC and DC isolators, generation meter and connections, etc.
