The production number to plan around
Use about 1,294 kWh per year per kW installed as the starting estimate for New Rochelle. It is a derived figure rather than a published municipal one: satellite irradiance data for the area with a standard performance ratio applied, which is a reasonable planning basis and no substitute for a survey of your own roof.
What moves the number on a specific house is the usual short list: which way the main roof planes face, how steeply they pitch, how much unobstructed area they offer once vents and chimneys are worked around, and what shades them across the year. Deciduous trees are the common surprise, because a roof that is clear in March can lose its afternoon by July.
It is worth asking an installer to show the modelled output plane by plane rather than as a single house total. A design that puts a third of the panels on a compromised face will still quote a respectable total while producing less per dollar spent than a smaller array on the good plane.
CitySquared is only half of the permit application
New Rochelle processes building permit applications through its CitySquared online system, but hard copies of all application documents, plans and payment must still be submitted in person or by mail. Until that step is done, the application is not in the queue. That is worth knowing before you file, because an applicant who submits online and then sits back is waiting on nothing.
Turn that into a question for your contractor before work is scheduled: who is delivering the hard copies, when, and how will you know the application has actually entered the queue. A contractor who works in the city regularly will have a routine for it. One who does not may assume the online submission was sufficient.
Keep your own copy of everything that is filed. If a question comes back on the drawings or the equipment specifications, being able to see what was submitted, rather than relying on a recollection of it, is what keeps a revision to days rather than weeks.
Con Edison and the Value Stack: what you are actually paid
Con Edison serves New Rochelle for electricity. New residential solar customers at New York's major utilities are compensated under the Value of Distributed Energy Resources framework rather than legacy flat net metering, and exported energy is valued by time-of-use and location-based components including energy, capacity, environmental and demand reduction credits.
A Customer Benefit Contribution charge also applies to new distributed generation customers, so the arithmetic is not simply generation minus consumption. VDER rates and terms are set by the New York Department of Public Service and vary by utility and rate class, and Con Edison administers its own tariff under that oversight.
For a homeowner the takeaway is about timing rather than totals. Power used in the house as it is generated displaces electricity at the price you would have paid for it. Power sent to the grid is valued by the stack instead. Anything that shifts household consumption into daylight hours, from running the dishwasher later to charging a car in the afternoon, raises the share of production that falls into the more valuable category.
An even split between houses and apartment buildings
New Rochelle is unusual in the evenness of its stock: single-family detached homes and buildings of 20 or more apartments each hold 38.1 percent of the housing units in the city. Those two groups face completely different projects under the same municipal rules.
If you own a detached house, you control the roof and the decision, and the path is a design, a permit filed and physically delivered to the city, and an interconnection application to Con Edison. Your constraints are structural and geometric rather than political.
If you live in a building of 20 or more apartments, the roof is controlled by a co-op or condo board and the building owner, and an array there normally serves a building meter rather than individual apartments. The work in that case is largely a governance exercise: getting one properly scoped proposal in front of the people who can approve it, with a clear answer on which account the production offsets.
Incentives: one large state credit and two closed doors
The NY-Sun incentive for this region is not available. The standard residential block at $0.15 per watt closed on May 29, 2025 and the income-qualified Affordable Solar block at $0.80 per watt closed on October 15, 2025, leaving no residential block open. Treat any proposal that still shows a NY-Sun deduction as a proposal that needs checking.
The 30 percent federal residential credit under Section 25D applied through December 31, 2025 and does not apply to a purchased home system placed in service after that date, so it is not part of a 2026 purchase. If you are considering a lease or a power purchase agreement, the provider may claim the business version of the credit and pass some of the value through in your rate. That is a question for the provider and a tax advisor, and it is not equivalent to claiming a credit yourself.
New York State's Solar Energy System Equipment Credit remains available and is the incentive that is left in this market: 25 percent of qualified residential solar expenditures, capped at $5,000, claimed on Form IT-255 with your state return, carrying forward up to five years if it exceeds your liability. It applies to purchased, leased and power-purchase-agreement systems at your primary New York residence. Because it is a personal income tax credit, its value to you depends on your own tax position, which is worth checking before you sign rather than afterwards.
