Ratings and reviews

This app takes you from your GPS location all the way through the financial aspects and payback period. Very complete solution for an App that doesn't have any ads. All I had to do separately was calculate the expected power usage and look up the efficiency ratings of the system components then enter them here. Some of the menu translations give unusual wording but it's not difficult to figure out what they mean.

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.

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.!
