To provide household electricity, solar panels typically produce between 250 and 400 watts each. A typical home may require between 5,000 to 8,000 watts of solar energy, which translates to a solar panel system capacity of 1 to 4 kilowatts23. Thus, the number of panels needed will depend on their wattage and the total energy consumption of the household. [pdf]
