Grid-Tied Solar Systems: Ballpark Estimated Costs



There are a lot of factors to consider when you're investing in solar power for your home. With Wholesale Solar's pre-wired grid-tie systems you'll be able to see what components are needed for your system and a ballpark figure of what you might expect to pay. These figures don't include the 30 percent Federal Tax Credit you'll receive for investing in renewable energy. To see individual system components, click on Wholesale Solar grid-tie systems below.

These figures are based on complete solar power systems that Wholesale Solar sells. Prices are approximate. Prices do not include racking, batteries, 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.

Comparing the True Cost of Utility Company Electricity with that of Solar Energy

Conventional fuel sources—oil, gas, coal, nuclear—have created a huge number of environmental problems. We pay with tax dollars, with higher prices for consumer goods, and with lower quality of life for acid rain, smog, water pollution, overflowing waste disposal dumps, the steady loss of natural resources, global warming and destruction of natural habitats.

Solar technology is allowing us to avoid many of these potential disasters. The silicon from one ton of sand has the potential to produce as much electricity as 500,000 tons of coal. One medium sized solar system will save the earth from 6,000 lbs. of carbon dioxide pollution.
