Best method for cleaning solar panels?

If you have plenty of power, usually all you need, then yes insignificant.

For those adjusting their consumption, usage to match their solar inputs, then it becomes significant.

I'm sure on a 100w 12V panel it makes more difference than to a 32V 300W panel.

it would = about .75 amp at 32v or just over 3 amps at 12 volts out of your panel.
On a 6 hour timeframe that is 18ah per day . Not an insignificant a mount .
So it pays to clean your panels at least once a month .
Just run a squeegee over them during a rain .
