New Article - Calculating Solar Panel Efficiency

One of the most popular questions we get asked at Photonic Universe is "How efficient is this solar panel?" 

This is a great question, and something we know many of our customers would like to be able to calculate for themselves - so to help you do exactly this, we've created a handy guide demonstrating how to quickly and easily calculate the efficiency for any solar panel.

The article explains how to calculate efficiency as a percentage, what sort of value you should expect, and why the efficiency doesn't affect the power you get out of your panel.

Check out the article here.
