The appliance a solar panel can power is determined by the total power output along with appliance wattage and the number of hours used. The total amount of power that can be produced by a solar panel depends on the solar panel's efficiency, wattage, sun hours, and many other factors.

The total energy a solar panel can supply is calculated by multiplying the wattage rating and the total sunlight hours received per day. A 100-watt solar panel will produce 300 and up to 500 Watts/Day depending on how many hours of direct sunlight it gets.
