How much will a solar electric system for my home cost?

All told, in leading states, the price drops [of solar components] and combination of incentives mean that an installed system could cost less than $10,000—a far cry from what solar was costing just a few years ago. And it means that some people are seeing payback periods of as little as 4 to 6 years.

The Cost of Installing Solar Panels: Plunging Prices, and What They Mean For You

Figuring out exactly how much your solar system will cost can take a little detective work. Electricity rates vary, and each state has different rebates that may affect the overall price of your system. Check out our state by state solar incentives page to see what extra incentives you qualify for beyond the 30% federal tax credit.

Use our quick calculator below to get a rough estimate of how much a solar panel system might cost you based on your location and the average electrical consumption in that area. If you have access to your power bills find the average kWh per month your house uses for a more accurate system size estimation.

Which type of system are you looking for?

  • Grid-tied systems are great for lowering your electrical bill, but require a connection to the utility company and go down when the grid goes down. Consider a grid-tie with battery backup system for emergency power.
  • Off-grid systems allow you to live and work with electricity in areas where utility power is either unavailable or too expensive to bring in. Off-grid is more about independence, but by living within your means, financially and energy-wise, you do save money.
  • What percentage of your house/business do you want to offset with solar power?
    "When we installed solar, the value of our home was increased by more than the cost of the system. We know that electricity prices will continue to climb, but not for us!" - Ellen, Wholesale Solar Employee-Owner.

    With Wholesale Solar’s current pricing (Jan. 2015), a medium sized gridtie system that generates about 850 kWh a month would cost about $10,680 BEFORE the 30% federal tax credit and rebates offered by your state or utility company. This particular system includes twenty four solar panels. The Federal tax credit would take the cost down to $7,350. This price does not include installation, which can be easily accomplished by a DIY-friendly homeowner or a trusted contractor.
