Get things right the first time with LUX Solar's DIY Kit Size Calculator

There are two types of solar system.

We believe that a solar system should actually meet your requirements and be sized correctly for you. Save yourself the hard work of ripping out cables, buying a new controller, trying to match your old panel with a new one that's not sold anymore and get your system design right the first time.
