Just installed. Very impressive on arrays and orientation. It would be good to have the capability of charging the battery at off peak hours, with an off-peak and day high rate. That would lead to estimates of smart usage of the grid in winter months, especially. Good to put in a battery but needs improvement. Also I would prefer to put in my kw demand to allow for heat pump use between times of the day. That all said 6 stars, but I would need to explore others, but this app has impressed me.

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.!

Hey Dave,
thanks for your feedback. I will consider this for a next update :) The directions for azimuth and tilt angle are described under help.
Best regards
