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.
The typical Australian household consumes about 16-20 kilowatt-hours of electricity per day. Using the example of 500-Watt solar panels each producing 2 kWh of energy a day would mean 10 panels should be enough. But it isn’t. Those 10 solar panels might produce enough electricity to power through the middle of a sunny summer’s day.
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. The power output (wattage) of the panels is rated based on how much power they can generate per hour under optimal conditions.
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.
