How do I calculate what size solar system I need?
To find out how to size your solar system, take your daily kWh energy requirement and divide it by your peak hours to get the kW power. Then divide the kW output by the efficiency of your panel to get the estimated number of solar panels you will need for your system.
What kW solar system do I need? You can simply divide your annual kWh by 1,200 and get the kilowatts of solar capacity you need. Therefore, if the power consumption reported in the last 12 electricity bills is 24,000 kWh, you will need a 20 kW system (24,000 / 1,200 = 20).
