Residential Solar Ownership Economics

Solar Tax Credits, SREC's, State Rebates

Owning your solar panels is similar to setting an investment account but with more certain and solid returns ranging from 11% to 24%.

With net metering credits, federal tax credits (ITC), SMART and state rebates, your solar energy costs are much less than your energy from your local utility.

You are currently paying $0.17 to $0.27 per kWh to utility (MA & NH rates). The cost of your owned solar kWh can be as low as $0.02 to $0.07 depending on roof orientation and exposure to sun.
