Photovoltaics

PV cells are suitable for any building with a southeast to southwest facing roof with no over shadowing.

PV systems use cells to convert solar radiation into electricity. A PV array fitted to a building can either be used to charge batteries or connect to the grid. PV cells are suitable for any building with a southeast to southwest facing roof with no over shadowing.

Solar Photovoltaics - Specifications
Type of System Monocrystalline Poly-crystalline Amorphous thin film Produces d.c. electricity - so to connect to the grid or run a.c. appliances will require an inverter.
Typical system 1.5kWp which will meet 1/3 of domestic household electricity requirement (lighting and appliances). Will need a roof area of 12-15m².
System Costs Typically £6- £7/Wp (approx. £8,000).
Energy Savings 1,200kWh/yr for 1.5kWp system
Development issues Speak to planning authority for permission. Should be ok if not a listed building or in conservation area. If shared roof (like tenement flat) then planning permission required). Building warrant will be required.
