Additional Solar Panels (break even)
The attached spreadsheet will allow you to estimate the amount of time needed to recoup the amount of money you spend to add additional solar panels to your Aptera.
There are three variables involved:
1. The amount of sunlight your location averages per day. The spreadsheet has a link that makes looking up your Avg peak solar hours very easy.
2. The price your electricity supplier charges per kilowatt-hr. Use $0.20 as a guess if you want. Keep in mind that as the price of electricity goes up, the time to break even decreases.
3. The solar panel configuration you choose to purchase. The calculator shows a break-even value for all four configurations.
