  1. Solar power is measured by insolation. The insolation rating of a particular area is the amount of solar radiation to hit the ground in a specific time period. This is usually figured in terms of kilowatt-hours per square meter per day (kWh/m2/day). A high insolation rating is a good indicator of a town"s potential for supplementing traditional power plants with solar energy.
