So, even though the average day is exactly 12 hours, the power you actually get on your panels is equal to about 5 to 6 hours of full sun per day. Since the typical modern solar panel is about 19% - 21% efficient, you will get about 1200 watts per square meter of panel. So, if the map says that you live in a "six" area, you can expect sun power
According to solar irradiance maps, we get 6.02 peak sun hours per day on average. In the winter, the average falls to 5.59 peak sun hours per day (7.2% reduction) . In the summer, the average increases to 6.71 peak hours per day (11.5% increase) .
Sep 21, 2022· Solar insolation and peak sun hours both express how much solar energy a location receives over a period of time. One peak sun hour is defined as 1 kWh/m 2 of solar energy. So, if a location receives 6 kWh/m 2 /day of sunlight, you could say that location gets 6 peak sun hours per day. Using peak sun hours makes it a bit easier to communicate
Although your panels may get an average of 7 hours of daylight a day, the average peak sun hours are generally around 4 or 5. Solar radiation peaks at solar noon, when the sun reaches the highest point in the sky. The number of peak sun hours you get per day increases the closer you are to the equator and typically during the summer months.
However, in the real world, Solar Irradiance varies throughout the day due to factors like the sun''s position and cloud cover. This variation directly impacts the power output (Watts) of the solar panel at any given moment. For instance, a 100-watt solar panel might produce 77 Watts right now, but a few seconds later, it could drop to 43 Watts.
