You may compare your location to the following two extreme locations. The average annual insolation levels for Central Australia: 5.89 kwh/m1/day- Very high and Helsinki, Finland: 2.41kwh/...

In order to calculate energy output you must input the following variables:Insolation level-Before you calculate your energy output, you should know the solar insolation level in your region. Take note of your max and min levels throughout the year as well as the annual average value. When assessing potential energy savings, input annual average insolation, and take note of the “per year” energy ...
