As I have approached many people about how to teach kids how solar power works I discover more that adults also need some answers.
One of the main questions I get about everything from home solar panels to solar garden lights and water pumps is “how long can solar power run my lights, pump, home, etc.”
There are a variety of answers depending on your own situation, for instance what type of battery storage are you using if any? For the solar garden lights you have a battery in the light that recharges during the sun hours of the day and discharges at night to power the light. After several cloudy days the lights do dim. However, if there was more energy storage or another battery, the light would last longer.
