Would solar panel powered objects last longer if we were closer to the sun?
Q. I have a solar paneled portable iPhone charger. If I held it higher to the sun, would the amount of time it would take to restore the battery shorten?
A. Sure! Great Idea!
Lets say you want to increase the speed by 10% and that recharge speed is directly proportional to light intensity, ok? ( A reasonable first approximation) So, since intensity is inversely proportional to distance squared we have 1.1 = d(high)²/d(low)² where low & hi are the two heights. That gives us â1.1 = d(high)/d(low)
or d(hi) = (â1.1)*d(low)
Since â1.1 ~ 1.05 we have the difference in height has to be about 5% of the distance to the sun closer to the sun to get a 10% increase in power. 5% of 93 million miles is 4 million miles (roughly).
So, if you will hold your panel about 4 million miles above the ground you can obtain a modest power increase.
HTH

This analysis presumes that the same light filtering our atmosphere does would be done on the phone. Of course at 4 million miles there isn't any atmosphere so the intensity would be lots and lots higher.
