It isn’t sunny enough for solar panels to work in the UK.
Truth: The UK receives between 1200 and 700 kWh of solar energy per metre squared. This might not mean much to you, but every meter squared of your house receives enough energy to meet a quarter of your electricity demand. PV panels are then able to convert between 12% and 18% of that into electricity for your home. The town of Freiberg in southern Germany is home to the largest solar PV plant in Europe and across the entire town solar PV provides 35% of electricity demand. Despite having a total installed capacity of 3,200 kW, Freiberg receives less solar radiation per square metre than southern UK.
