In order to find a range for number of solar panels we compared arizona and maine s solar panel production ratios 1 31 and 1 61 the highest and lowest in the u s. How many solar panels are needed to power an average house. However most installers estimate solar costs by the amount of energy needed at 2 53 to 3 15 per watt before any tax credits or incentives. Given 1kw of panels produces 1642 kwh per year in ca and 1kw of panels takes up 68 42 square feet solar panels installed in california on average produce 23 99 kwh kilowatt hours per square foot per year.

You can use the table of solar power production per kw for each state above to do the same math for your state.
