June 2022 just slightly sunnier than average
In order to quickly and correctly assess the efficiency of your solar panels, it is important to take into account the solar radiation.
In order to be able to calculate in a simple way with data on solar irradiation, it is assumed as an international standard that at "full sun" a power of 1,000 Watts per m² is irradiated on the earth's surface. In other words, one hour of full sunshine produces 1,000 Wh per m² or 1 kWh/m².
Slightly above monthly average
