Generating Electricity from Moonlight

Here are the problems you’re going to run into:
It’s possible that this lens concentrates the incident light, but it doesn’t magnify/amplify it.
The incident power from a full moon is 0.00146 Watts per square meter, or one six-millionth what we get from the sun at the equator. The average home rooftop solar installation is 26 square meters; for moonlight, it would be 4,166,666 square meters, which is 1.6 square miles. That’s a big rooftop.

Just thought of another issue here, as if it needed one. Full moons reach their zenith at about midnight, where power is needed least.
