What people think about this app…

  • Very easy to use

    Very simple and easy to use. Not being an electrician it really helps to find values.

  • 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!
