Determining the right solar capacity for your energy needs is crucial. By following a simple calculation method, you can easily determine the kilowatts of solar capacity required.
To calculate the solar capacity needed, divide your annual kWh by 1,200. For example, if your total energy consumption over 12 months is 24,000 kWh, you’ll need a 20 kW system (24,000 / 1,200 = 20). Understanding this calculation can help you size your solar system accurately and efficiently meet your energy requirements.
You can simply divide your annual kWh by 1,200 and you will get the kilowatts of solar capacity needed. So, if the energy consumption reported on your last 12 utility bills adds up to 24,000 kWh, you’ll need a 20 kW system (24,000 / 1,200 = 20).
