How We Ranked the Best Solar Panels
We looked at a wide range of solar panels from leading manufacturers and evaluated them based on a number of factors before coming up with our list. The following are some of the variables we considered when compiling our list:
Efficiency
According to the efficiency rating, the amount of sunshine that a solar panel can actually convert into usable electricity is measured. Remember that the efficiency of solar panels peaks at slightly over 20%, and in general, the most efficient solar panels will result in the highest savings for your home in terms of energy.
