The rated output of solar panel modules is assessed using the full hours of sunshine per day where one full sun hour is defined as being exposed to a solar intensity equal to 1,000 watts per square meter. Full sun hours do not indicate the number of hours that the sun is shining in a day, but rather is an indication of the intensity of the sun. Also important to note is that not all of the sunshine that strikes a solar panel cell will be converted into electricity. Typically, 15% to 25% of the energy produced is lost because of inverter and wire losses. |
