How do solar panels work? Solar power explained
Concentrated solar power. Concentrated solar power (CSP) works in a similar way to solar hot water in that it transforms sunlight into heat––but it doesn''t stop there. CSP technology concentrates the solar thermal energy using mirrors and turns it into electricity. At a CSP installation, mirrors reflect the sun to a focal point.
