The system size (in watts) can be determined by dividing the total watts of the solar panels by the wattage of an individual solar panel. For example, an average 4-bedroom house in the US would require a 7.75 kW solar array, consisting of 375 W panels.
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.
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.
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
