On average, a 100-watt solar panel can produce between 300 to 600 watt-hours (Wh) of energy per day, depending on your location's sunlight hours, weather, and panel orientation.
A 100-watt solar panel will produce roughly 100 watts of electricity in an hour. So, if you use a 100-watt light bulb for an hour, it will use up the same amount of energy that the solar panel produces in an hour. Let's say you have a 100-watt solar panel and you use it for an entire day. In a day, the sun shines for about 12 hours.
One watt-hour equals one watt operating continuously for one hour. For example, if your solar panel produces 100 watts of power for one hour, it will send 100 watt-hours of energy into your home's battery bank or your local power grid. The more watt-hours a panel produces each day, the fewer panels you need for a given application.
