Big Jimbo Posted June 1, 2023 Share Posted June 1, 2023 Thinking about solar. My southish facing roof only has a pitch of 30 degrees. I'm looking at solar to see if it might be worth adding to the roof when i build the house. Is 30 degrees too low to make it worthwhile even considering ? Are there any websites that would give me some idea of the suns movement, and potential solar power generation. Is East or West facing solar panels even worth considering ? Thanks for any help.

JohnMo Posted June 1, 2023 Share Posted June 1, 2023 30 degrees is fine, you will get slightly better summer performance than winter. Nothing wrong with east or west either, both is better than one or the other - you get good production from first thing, until sunset, with a slight dip at midday. 1 Link to comment Share on other sites More sharing options...
S2D2 Posted June 1, 2023 Share Posted June 1, 2023 PVGIS: https://re.jrc.ec.europa.eu/pvg_tools/en/#MR Nothing wrong with that pitch, PVGIS will show you the generation which you can compare to South, probably less of an impact than you were expecting. West has the unexpected benefit of pushing more generation into the peak flux export window, if you're installing batteries too. 2 Link to comment Share on other sites More sharing options...
