I like it

It works well. 👍

Not ideal.

Apps does the required calculations but only if you can get passed the adverts. Essentially you can’t always use it unless you willing to watch ads. Personally I just deleted the app because on this occasion it’s literally refusing to do the calculation without me running ads first.

Solar Calculator

This app has been very useful in setting up a solar array. I’m old school and could do the math myself to convert the current, but this app is faster and accurate leaving me the time to design panel racks and other mechanical issues. Could’ve used this years ago. Overall a very useful app for the novice and the pro!
