June 23, 20206 yr i think this has to be one of the best PV performance calculators. https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html
June 23, 20206 yr So i compared my real life results to the calculator. The calculator is good for Jan-March, from April its way out...Too low by far.
June 23, 20206 yr Would I be correct in understanding that the Azimuth for us in South Africa would be a negative number, like -150 as an example depending on your roof? If I understood it correctly, 0 is South? So -180 would be North?

Ok cool, thanks, appreciate it. Pretty cool tool to use. I don't have Solar myself, but it will be great to use as a benchmark to understand what's possible.
