How It Is Used
The sensor is pointed towards the sun, or held in the plane of a solar panel, and the display gives the solar power arriving per square metre. Comparing this with a panel's electrical output lets students work out panel efficiency, and readings taken at different places and times support site surveys and studies of how the atmosphere weakens sunlight.
