Standard Efficiency Panels (350-400W) These panels represent the most budget-friendly solar options and work well for homes with ample roof space. Modern standard efficiency panels from quality manufacturers deliver reliable performance at lower upfront costs. For a typical 7 kW system, expect to need 18-20 panels in this category.
12,000 / 1.6 / 0.4 = 18.75 panels (round up to 19) While energy usage varies significantly between households, home size provides a useful starting point for estimation: Smaller homes typically use 6,000-9,000 kWh annually.
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
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.
