The sunpower x series panels are 345 watts each. The exact number changes depending on the specifications of the chosen panel model as well as the sunshine available at the project site. We then took 11 000 kwh and divided it by the respective ratios and then divided that number by 250 the typical panel wattage. 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.

For example if you need 4 000w hour as tabulated in the example above and have 250w solar panels. A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels.
