## How are solar panels calculated?

You can calculate how many solar panels you need by multiplying your household’s hourly energy requirement by the peak sunlight hours for your area and dividing that by a panel’s wattage. Use a low-wattage (150 W) and high-wattage (370 W) example to establish a range (ex: 17-42 panels to generate 11,000 kWh/year).

## How do you calculate kW for solar panels?

Crunching the numbers – Input both of the figures above (average kWh usage and peak sunlight hours) into the formula below: average monthly kWh usage / (peak sunlight hours x 30 days). So, using the numbers above: 877 / (4 x 30) = 7.3 kW solar system.
