Normally, solar panels work best at around 90% of their maximum ...
How to Size a Solar Charge Controller
1. Find your solar panel''s short circuit current (Isc). You can find this number on a label on the back of the solar panel or in its datasheet. In this example, my 100W panel''s Isc is 5.86A. 2. Multiply the panel''s Isc by the number of panels or series strings you have wired in parallel to get the short circuit current of your solar array.
Short-Circuit Current
For an ideal solar cell at most moderate resistive loss mechanisms, the short-circuit current and the light-generated current are identical. Therefore, the short-circuit current is the largest current which may be drawn from the solar cell. The short-circuit current depends on a number of factors which are described below: the area of the solar ...
