The intensity of solar thermal energy from solar radiation at the surface of the earth is about 1 kilowatt per square metre (0.093 kW/sq ft), of area normal to the direction of the sun, under clear-sky conditions. When solar energy is unconcentrated, the maximum collector temperature is about 80–100 °C (176–212 °F). This is useful for space heating and heating water.
