The average one-bedroom house needs six solar panels, a typical three-bedroom house requires 10 panels, and a five-bedroom house will usually need 14 panels. In each case, the panels will produce enough power to cover 49% of the average household’s annual electricity usage – or more, if you don’t leave the house very often and use less electricity.
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.
