50 watt 100 watt and 160 watt.
In 2018 monthly average electricity usage in california was 547kwh.
This works out to 15 sixty cell 275 285 watt solar panels or 12 seventy two cell 350 watt solar panels.
There is some variation from brand to brand and if you re installing a large scale solar panel system such as for a warehouse or a municipal building your panels will be closer to 6 feet long.
You ll need 6 2 kw dc according to the formula.
The average size of solar panels used in a rooftop solar installation is approximately 65 inches by 39 inches or 5 4 feet by 3 25 feet.
