Does solar power 🌞 work on cloudy, rainy days? 🌧
The volt meter on my truck says the battery voltage is 13.7 volts. That means the battery is charging with the engine off. 🔋 Once the sun angle decreases and panel output drops, the voltage will drop to 12.6-12.7 volts as no charging will occur.
So yes, solar does work on cloudy, rainy days. 😎
