Is solar worth it in the United States?
A 6 kWp system is a common size for a family home. The figures above use the United States’s typical install cost, electricity price and export rules, then model 25 years of savings. They are an estimate, not a quote: your roof, orientation and shading move the result, which is what the calculator works out for your exact address.
