The Complete Guide to Solar Inverters

If you have 20 solar panels with a rated voltage of 6V each, the maximum potential output during peak sun hours is 120V. However, if just one module is in the shade (or damaged) and only produces 4V, the array''s output will be reduced to 4V per panel. Instead of 120V of production, your panels will output 80V.
