How can I tell if my solar panels are working properly?

A simple health check is to look at the colour of the lights shining on the box during daylight hours when the system's meant to be running. A green light on your inverter means your system is functioning properly. A red or orange light during daylight hours means there's a system event or fault.

Does moonlight charge solar panels?

The answer is a definite YES, because Moonlight is nothing but reflected Sunlight. Solar pv panels do convert moonlight to electricity. It can be used to power PV cells at a cost of 345:1, meaning, a panel that would normally produce 3450 W at high noon would produce only 10 W of power during the full moon.
