If you are in an area with a high number of average hours of sunlight, each solar panel will receive more light, and thus produce more power, so you may need fewer panels to power your home. To estimate the number of solar panels you need, look at three variables: Solar panel rating, production ratio, and annual electricity usage.
For the calculations below, we use 400 watts as an average solar panel rating of the power solar panels produce. Production ratio: The ratio between the estimated energy production of the system over time (kWh) and the actual size of the system (W).
Since this number can fluctuate based upon the peak solar hours a region receives, we recommend doing calculations with the range of 1.3 to 1.6. Annual electricity usage: The amount of electricity you use to power your home over the course of a year, measured in kilowatt-hours (kWh).
Typically speaking, the more energy you use, the more solar power you need. The opposite is true for peak sun hours. If you are in an area with a high number of average hours of sunlight, each solar panel will receive more light, and thus produce more power, so you may need fewer panels to power your home.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
