HOME INSTALLATION
The following example reflects the cost of solarizing a home in Michigan. Depending on the electricity usage and available areas to install a solar system, the home-owner can offset most of their electric bill.

System Size:                                                                       5kW
Installed Price per Watt DC:                                           $6.50*
Gross System Cost:                                                    $32,500
Utility $2.40/Watt Rebate:                                           $7,200**
Subtotal:                                                                        $25,300

30% Federal Tax Credit on Tax Basis Cost:           $9,750
Net System Cost:                                                         $15,550
Accellerated Depreciation (5 Years)                        $11,050
(.85% or overall cost – 40% tax bracket)
Net Cost                                                                        $4,500
Annual revenue = $660. Payoff of upfront costs is less than 9 years. Remaining 21 years of of production = $13,860. Terminal value after 30 years is projected to be $15,000

* This number will vary. Amounts depend on a number of variables (system size, roof slope, roof membrane, ground mount option, etc.). Our solar professional will provide you a FREE personal analysis.
**Assumed value to be determined by utility.   Renewable Energy Credit income is taxable

The example below illustrates the cost of a commercial installation.

System Size:                                                            20kW
Installed Price per Watt DC:                                 $6.00^
Gross System Cost:                                               $120, 000
Less 30% Federal Tax Credit:                          -$ 36,000
After-Tax Credit Subtotal:                                       $84,000
Utility $2.40/Watt Rebate After Tax Value^^    -$28,800
Net Cost                                                                   $55,200
Five year Accelerated Depreciation:                   $40,800
Net System Cost:                                                   $14,400
Yearly revenue = $2640. A 5 year loan @ 5% interest has payments of $2442.36 per year.
Payoff: less than 7 years. Remaining 23 years production = $60,720 and a terminal value after 30 years estimated to be $20,000.

^^This number depends on your tax bracket and accounting regulations. (This calculation assumes 34% Federal & 6% State tax rate). Rebate income is taxable. Renewable Energy Credit Value is taxable
