50% of the cost of materials and labor
Indiana allows taxpayers to take a deduction on solar-powered roof fans (or vent, also sometimes called an attic fan) installed in a home that the taxpayer owns or leases. The deduction is for 50% of the cost of the materials and installation labor, up to $1,000. Proof of costs and the names of the suppliers and/or installers are required.
