Automatic Solar Rotation System in Pakistan. Ali Jehan Z3b
Easy to use and beautifully made
Some fantastic functionality for a free app. Easy to use and good documentation. The big problem is that it never tells you angles used to make the final graph. i.e. Tilt, and degrees from north. Which is a major pain if you're wanting to use that data to make a frame too hold the panels. It would be great if you could see these listed on the graph at the end.
I live in Australia and suspect that the application is not valid for the southern hemisphere, as the ordinal letters (N, E, W, S) do not line up with 0, 90, 270, 180 degrees and I appear to have only 90 degrees of movement when I rotate my phone through 360 degrees in azimuth for taking the horizon scan. Unless changes can be made to what appears to be a well thought out application, I recommend that southern hemisphere users leave it alone.
Really great tool for investigating solar potential in particular place. Addition: It would be great to display numerical values for current tilt/azimuth along with effectiveness percentage.
NASA Surface meteorology and Solar Energy data implemented in the app.
Direct and diffuse solar radiation now calculated in the app.
Direct solar radiation based on NASA data takes into account the atmospheric beam attenuation and weather conditions.
Diffuse solar radiation based on NASA data.
