Solar power refers to energy derived from the sun in terms of either direct heat or daylight. The sun could easily provide all the planets power needs; the problem is capturing it.
Solar renewable systems can be divided into two types; Solar thermal, which relies on heat from the sun to provide heating and hot water, and solar photovoltaics (PV), which converts daylight into electricity. Incentive payments including feed-in tariffs (FIT) for solar PV installations have been withdrawn for new installations.
PV can bring savings on your electricity bill through using electricity generated by the PV cells rather than mains electricity. PV works best where there is an on-site demand for the electricity produced that matches the yield profile of PV, for example, powering shed cooling fans that operate during summer days. A survey carried out by Farming Futures suggests that 80% of farmers would like solar PV on farm roofs.
