Solar / Output of solar panels depending on slope and azimut
« Last post by Adriaan Kragten on March 13, 2024, 06:19:32 AM »Recently I found a very interesting website of PVGIS Europe. On this website you can find the output of solar panels depending on the country, the total peak power, the slope and the azimuth for every month of the year. I have written the small Dutch note: "Opbrengst van zonnepanelen in december afhankelijk van de dakhoek (slope) en de stand t.o.v. het zuiden (azimuth). This note can be copied from my website: www.kdwindturbines.nl at the menu KD-reports at the bottom of the list with reports. Figure 1 out of this note gives a direct impression of the effect of the slope and the azimuth for December. Although the note is in Dutch, this figure can be understood by everyone (dakhoek = slope). The figure gives the reduction factor for the output if the solar panel is compared to a panel with a slope of 75° and an azimuth of 0° in The Netherlands. December is the most difficult month for solar power at the northern hemisphere and therefore this month is chosen. But a similar figure can be made for every other month and every other country in Europe using the website of PVGIS Europe. For America, you have to chose a point on the map of Europe with the same latitude.
