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!
