The goal for any solar project should be 100% electricity offset and maximum savings — not necessarily to cram as many panels on a roof as possible. So, the number of panels you need to power a house varies based on three main factors: In this article, we’ll show you how to manually calculate how many panels you’ll need to power your home.
As we calculated earlier, the California household needs a 7.2 kW system to cover its electricity needs. A comparable household in Massachusetts needs a 9.9 kW system. So, in less sunny areas like Massachusetts, you might consider choosing highly efficient solar panels to maximize your energy output per square foot.
System capacity: solar arrays are usually sized in kilowatts (kW). A 5 kW system has panels totaling around 5,000 W. To estimate required panel count, you need to understand your home’s daily electricity consumption.
The average U.S. household uses about 30 kWh per day, but this varies—smaller homes might use 15–20 kWh, while larger homes with electric heating or EVs could use 40–60 kWh daily. The next step is to estimate how much energy a solar panel will produce where you live.
Our photovoltaic container solutions including 20ft/40ft containers, custom mobile containers, commercial and industrial energy storage systems are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
