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**
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.
