Incentivizing Solar in NYS

How much does it cost to install a residential solar system?

That depends on a variety of factors, including system size, roof type, roof slope, and municipal permitting process. For example, the larger the system, the higher the costs, but the lower the average cost per watt installed. The steeper the roof, the higher the cost. Is the roof material composite shinge? Asphalt shingle? Tile? Slate? Some materials are easier to work with than others, which factors into the cost. Is the roof one story or three? The higher up we have to transport your panels, the higher the cost.

To provide an indication of what most people pay, we turn to NYSERDA, which provides the most accurate data on the New York State solar market.

In 2023, the median pre-incentive cost for a solar array in Westchester, NY was $31,447 for a 7.2 kW system, according to NYSERDA internal data published here. The median post-incentive cost was $15,658.

Most solar installations qualify for NY Sun Residential Block 9, NYS Solar Energy Equipment Credit, and Federal Residential Energy Credit. The Federal Low-Income Bonus Credit and Federal Domestic Content Bonus Credit require special applications.

This tax credit can only be accessed during a specific application window and is only available in low-income neighborhoods and/or for qualifying affordable housing.

Federal Domestic Content Bonus Credit


No solar module manufacturers have yet qualified for this tax credit, which requires the bulk of the module components, inlcuding the solar cells be manufactured in the United States.

Post-Incentive Total


Breakdown of cost by category below


Labor: this is a function of the number of employee hours it will take to build the array multiplied by the cost of each hour.

Solar modules

The cost of solar modules has fallen significantly over the past decade, by around 90%; however, they still represent the single most expense part of the installation.


The inverters, whether micro inverters or string inverters, represent the second most expensive equipment expense behind the modules.

Balance of System

Balance of System comprises the conduit, wire, cables, racking, breakers, and combiner boxes.


Permitting is the administrative hours and fees related to preparing and filing permits with the local municipal government, the utility company, and NYSERDA.


Inspection includes the administrative hours and fees related to scheduling and completing electrical and building inspections as necessary.


Our base pricing is based on a standard, composite shingle roof in good condition of average slope, a functioning, standard size main electrical panel, and a house no more than two stories in height. Steep slopes, electrical service upgrades, heights greater than two stories, tiles, slate or other hard materials will result in higher prices.
