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. 1

This form has been pre populated with data specific to your area.
For more accurate results, fill in the fields below with numbers from your own electrical bill.
Your average monthly electrical usage or average monthly bill

The U.S. Energy Information Administration says an average US household uses about 900 kWh of energy a month, but this varies greatly between households and locations.

For the most accurate estimate, either:

  • Look at your electric bills from the past 6 months to a year, taking into account summer and winter differences. Average them out into a monthly kilowatt-hour (kWh) usage. This is the amount of energy you use every month, on average.
  • You can also estimate the power used by your individual appliances with our Load Evaluation Calculator or measure the power usage of each appliance with a Kill A Watt Meter. The Neurio Home Energy Monitor also give excellent real-time monitoring of your energy usage. Multiply the result there by 30 (for a month) and then divide by 1000 (to convert to kWh).

Your cost of electricity per kWh

Ask your utility provider or check their website if you don't know.

The average number of daily sun-hours your area receives

This is used for calculating the appropriate system size for your area and your payback time. You can use our sun-hours map to look this up if you need to.

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 or a Kohler Generator 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?

    Most people want to offset 100% of their power bill for maximum savings. However you can always start with a smaller system and expand later.

    "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.

    Grid Tie
    Off Grid

    With Wholesale Solar’s current pricing a medium sized gridtie system that generates about 850 kWh a month would cost about 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.
