• Greater uptake of solar PV, supported by the Feed-in tariff scheme, led to generation in 2012 which was nearly four times higher (up by 944 GWh) than in 2011, at 1,188 GWh.
  • Solar PV installed capacity in the UK increased from 10.9 MW in 2005 to 1,705.5 MW in 2012.
  • Despite the large annual increase however, just 3 per cent of renewable generation came from solar photovoltaics.
  • Solar PV electricity is renewable once the installation offsets the carbon emitted during its construction. A typical 2.5 kWp system could provide up to 50% of a household's annual electricity, saving around 1200 kg of CO2 per year and around 30 tonnes over its lifetime.
  • Each installed kWp can be expected to produce around 850kWh (units) of electricity per year in the UK. A 2kWp system would thus produce approximately 1,700kWh/year, around half of the annual electricity consumption.
  • In the UK we receive sufficient sunshine to provide up to 70% of our annual domestic hot water needs from well designed solar panels and such a system will also reduce harmful emissions by up to 500 kg per square metre of solar panel per year.
  • The earth receives more energy from the sun in just one hour than the world uses in a whole year.
  • A world record was set in 1990 when a solar-powered airplane flew across the United States in stages, using no fuel at all.
  • The Bentley Motors Factory has the UK's largest rooftop solar PV array with 20,000 solar PV panels generating enough electricity to power 1,200 households.
  • The world's largest PV solar generating facility is currently being built in Arizona, expecting to be completed it in 2014; it will reach an installed capacity of 397MW.
