Dirty vs Clean Solar Panel Power Output Comparison

RPS Solar Pumps hooked up a dirty solar panel to a constant voltage DC electronic load, setting the voltage to 36V and found that our dirty panels were outputting about 4 Amps which is equivalent to about 145 Watts. Then they cleaned the panels and saw in increase to 5.1 Amps (183 Watts). Watch a live example of the full power you can expect in typical conditions, after you clean your solar panels.
