25% tax credit capped at $5000 for solar electric systems (photovoltaic)
You can carry forward the tax credit for up to 5 days until you have used it.
25% of what? It is 25% of the cost after any utility provided rebates. This is made clear in the statute.
This credit is subject to federal tax.For example, if you receive a state rebate in 2010 for a system placed into service in 2009, then in April 2011 you will owe federal income tax on the state rebate (thus reducing the value of the rebate).
Most areas have property tax exemptions for solar and energy conservation improvements.
Other incentives these are mostly outside of LIPA service region, NYSERDA excludes LIPA service region.
