Excellent app, by far the best I've ever seen. It's an outstandingly powerful tool covering complex situations with flexible and customisable input as well as data analysis, whilst everything remains user-friendly, nicely organized, clearly understandable and visually attractive. This is exactly what I needed for designing my solar system and finding the best and the most optimized configuration among myriads of possibilities. Surprisingly, for such a value there are no in-app purchases nor ads.

A nice tool for a quick understanding of expected results around the world. To make the output calculation more flexible, the programmer might consider user-defined load profiles (a school or office doesn't fit the 5 standards that are offered). I also had some misunderstandings with the Azimuth, where 0 degrees is defined as South-facing. Maybe I'm stupid but, for whatever reason, I had trouble with that! A quick test with inclination at 90 degrees helped me. Thanks for your app.!

Cannot get it back on grid results.

The app appears at first to be good but the reason you get the app is to see if tomorrow onwads is going to be a good generation day or not This app appears not to offer any off this just Generic yearly quarter All its done is tell me what I allread new

I live in Vegas , not even close, April and September are the most productive days because of the high temps in summer time , this app was not even close of properly estimating that
