Solar panels in power stations
The land area required for a desired power output varies depending on the location, the efficiency of the solar panels, the slope of the site, and the type of mounting used. Fixed tilt solar arrays using typical panels of about 15% efficiency on horizontal sites, need about 1 hectare (2.5 acres)/MW in the tropics and this figure rises to over 2 hectares (4.9 acres) in northern Europe.
