Off-Grid Solar Systems: Ballpark Estimated Costs



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.

These figures are based on complete solar power systems that Wholesale Solar sells. Prices are approximate. Prices do not include freight, tax, or installation.

Why are smaller systems sometimes more expensive than larger ones? Because higher-efficiency panels cost more. For example, to get a 10 kW system, you can either use 35 285W panels or 39 260W panels. Even though you need more 260W panels (they are less efficient), economies of scale actually make them more affordable. So when would you want to use higher-efficieny panels? Only when you're limited on roof/ground space and need to squeeze the most power out of every available square foot. In other words, more efficient panels cost more but can generate more power per square area. If you're not limited by space, we suggest you go with the best price per watt instead.
