Rebate Explanation

The price of your Ecodwell home is contingent on selection of custom features and lot condition, as well as state and federal rebates.

For solar systems, there are two primary sources of funding: State Rebate and Federal Tax Credit

State Rebate

Illinois residents can get a 30% rebate (up to $10,000) from the State of Illinois for solar thermal and solar electric systems. Rebate funds are allocated on a first come, first served basis until the budget for the year is depleted. In the past, overflow applications have been added to a waiting list for the subsequent fiscal year. The State Rebate program is in effect until 2016.

Federal Tax Credit

Homeowners are also eligible for a 30% federal tax credit (uncapped) for solar thermal and solar electric systems (PV). The tax credit was extended by the IRS (effective January 1, 2009) until 2015.

Example Rebate Calculation

The cost to purchase and install two solar hot water panels is $11,000. First, the State Rebate is applied (30% of $11k) for $3,300 back. Then, the Federal Tax Credit is deducted from the remaining amount of $7,700 for an additional $2,310 back (30% of $7,700). So the net installed price is actually $5,390.

Green Permit Discount

Generally, it costs about $5,000 to get a building permit. This is an additional expense to construction. Fortunately, the Green Permit process practically eliminates the entire amount with a discount of approximately $5,000.
