Step 3: Your Region - Irradiation >>>


Step 3: Solar radiation of your geographical region


The yearly sum of solar radiation changes with the region. The further south you are living (on northern hemisphere) and the more sunshine in your region the better is the so called global radiation (insolation). With other words the more solar electricity you can harvest from your photovoltaic system. The maximum values of solar radiation occur south and north of the equator.
