Off-Grid System Cost Guide
Putting together an off-grid system on your own can be a bit mind boggling, especially when you're trying to figure out your costs. To help alleviate some of the work, the renewable energy experts here at Wholesale Solar have put together some pre-designed packages. We have a wide variety of packages from small systems to power only a few key loads to large packages that will power an entire house.

See the cost guide below, so you can get an idea of your needs and what you might be spending. If you click on each system example below, you'll be able to see what components are included in a given off-grid package. Bear in mind that the costs below will be lower when you apply your 30 percent federal tax credit.
