What are Photovoltaics?

Photovoltaic or PV systems convert sunlight directly into electricity that can serve a portion of your electrical needs. PV systems are connected to your electrical service panel and are used to supplement your existing utility service. When the PV system is generating more electricity than you use, it is as if the meter spins backwards, and you will receive a credit for the excess power from your utility. This process is known as net metering. With proper location, a PV system works anytime the sun is shining. It works best when facing south and must not be shaded by trees, nearby buildings, or other obstructions.

Why buy a PV system?

*PV systems are gentle on the environment. In contrast with electricity generated by fossil fuels, PV-generated electricity creates no noise, air or water pollution.

*Provides long term stabilization of electrical cost

*When combined with a battery backup system, a PV unit can provide you with power when utility power is out.

*NYSERDA provides incentives for up to 7kW or less for residential, 25kW or less for not-for-profit and 50kW or less for commercial sites.

*Federal and NYS Tax Credits

How Much Can You Save?

It depends on:

*how much electricity you use

*the size of the PV system

*how sunny the local area is

*the orientation of the PV panels

*how much you pay your utility for electricity


For example:

A nine-kilowatt PV system located on the south-facing roof can typically offset 100% of a home’s electricity needs. When combined with improving the energy efficiency, the savings on your electric bill can be even more significant.

A nine-kilowatt system will produce about 11,000 kilowatt hours of electricity annually. A typical New York residential home uses about 9,500 kilowatt hours annually. For a typical seven kilowatt PV residential system, the approximate installed cost is $34,000 before incentives. NYSERDA’s PV Incentive Program and potential tax credits* can significantly reduce the same system to approximately $12,000.


*You may qualify for up to 30% federal and 25% (up to $5,000) of New York State tax credits for your primary residence. (Always consult with your qualified tax professional or accountant to determine your eligibility for tax credits.)
