As we've learned, an average U.S. home requires between 17 to 25 solar panels to meet its energy needs. By understanding your specific electricity needs and calculating the output of potential solar panels, you can confidently estimate how many panels you'll need to power your home. Can a house run on solar power alone?
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.
So, a daily consumption of 30 kWh is a good starting point. Next, you'll need to know how much electricity one solar panel can produce. Solar panels come in different sizes and power outputs, typically ranging from 300 to 450 watts per panel.
It's just a general rule – the actual amount of electricity generated per kW of solar panels depends on your location, the time of year and the amount of sunlight you're getting, the quality of the system, the orientation of the panels, how old they are, and so on.
