Do solar panels work with Moonlight and how much power do solar panels produce in the winter?
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. Solar panels need light preferably sunlight to create energy. Although they can generate some energy from other light sources such as street lights and even the moon, the output is very low. Moon energy is not an entirely new concept. One power source already in operation relies on the moon's gravitational pull to spin its generators. Tidal power plants arranged like hydroelectric dams have been around for decades. The reality is that the electricity generated by solar panels at night is minimal. On a perfect night, with no cloud cover and a full moon, a solar panel will only produce between 0.2%- 0.3% of the normal energy they would produce in direct sunlight. This amount of energy isn't even enough to power a basic light bulb. On a clear night with a full moon, you should only expect 0.3% of the energy production that you would experience in direct sunlight. That means that if your solar panels typically produce 300 watts of power during the daytime, they will only generate roughly one watt in direct, full moonlight. Given that moonlight is just sunlight reflected off the moon, you'll be relieved to learn that yes, solar panels can operate with moonlight. Your solar panels will, however, create very little power at night, even if the moon is shining directly on them with no clouds in the sky. To illustrate why solar panels would not work at night, it is useful to calculate the amount of energy within moonlight. A full moon leads to illumination equaling 0.108 lux. A lux, by comparison, equals 1 lumen per square meter. This corresponds to energy of approximately 0.0006 watts per square meter.Even in below-freezing weather, solar panels turn sunlight into electricity. That's because solar panels absorb energy from our sun's abundant light, not the sun's heat. In fact, cold climates are actually optimal for solar panel efficiency. So long as sunlight is hitting a solar panel, it will generate electricity. System Size X 2.6 = kWh avg daily winter output. So for a 5kW system, this would be 13kWh a day on average. So a 5kW solar system should on average produce around 20kWh per day. You will likely see much more power produced during great solar days in summer, probably up to 30kWh and much less power produced during a cloudy winter day maybe lower than 10kWh. But over the year it should average out to around 20kWh.
