How many solar panels do you need to power a house?

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.

How many solar panels does a home need in 2025?

Complete 2025 Calculator & Planning Guide Location Impact is Massive: The same home using 1,000 kWh monthly could need just 16 panels in sunny Arizona but 22 panels in Massachusetts due to solar production ratios varying from 1.0 to 1.8 across different regions.

How many kW solar panels do I Need?

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.

How do I calculate how many solar panels I Need?

You can calculate how many solar panels you need by dividing your yearly electricity usage by your area's production ratio and then dividing that number by the power output of your solar panels. To put it simply: Number of panels = annual electricity usage / production ratio / panel wattage
