The electricity output from a solar power facility connected to a grid can be read in kilowatt-hours directly from the supply meter. Depending on their region, exposure and mounting, as well as on the quality of their components and their calibration, solar power facilities in Central Europe yield an average output of 800 to 1400 kWh per kWp and year. In just one hour, enough solar energy reaches the Earth to meet the entire human consumption for a year.
