How Solar Works in Buffalo, Step by Step

Begin with the electric bill for the installation address. Identify the company responsible for electric delivery, then ask it which solar interconnection process applies to your account. Do not infer service from a Buffalo mailing address, a nearby installation, or our community list. If your bill names National Grid, its residential getting-started guide says an interconnection agreement is required and the installer typically handles the application. If your bill names another utility, ask that company for its own requirements before relying on a proposal.

Also establish which municipality has building jurisdiction. The City of Buffalo process below concerns property inside the city. Towns and villages outside Buffalo have their own building departments and local processes; ask the department responsible for your property which office handles your project. Keep the utility account, municipal jurisdiction, and property details together when comparing proposals. Ask who will confirm this information and correct an application if an address or account detail is wrong.

Before selecting equipment, ask the installer who will inspect the roof and assess its remaining service life. Does the roof need repair first? Who evaluates the structure, attachment method, waterproofing, and proposed panel layout? Ask how shading, roof direction, access for maintenance, and any existing roof warranty enter the design. These are questions for a site assessment; this guide has not established that any particular Buffalo roof can support an array.

For the electrical work, ask who will review the service panel, available capacity, proposed connection, equipment locations, and any required upgrades. Request an explanation of which work is included in the proposal and which conditions could require a revision. If you want storage, ask for a separate explanation of battery placement, backup circuits, controls, and additional approvals. Ask whether the person preparing the plans and the people doing the work have the qualifications required for that scope. Get the answers in writing before accepting a final design.

For residential rooftop solar inside Buffalo, start with the Department of Permit & Inspection Services. Its permit process begins with project registration by the designer, contractor, or owner. The current City application portal lists solar work as requiring two permits: Repair and Electrical. Ask the permit office which repair application fits your rooftop project and what drawings and supporting documents it needs. An online application is a way to submit the project, not an approval to start construction.

The City’s plan review page directs applicants to file drawings digitally through ePermits. The City’s permit-process page also describes zoning compliance checks and possible preliminary site-plan or Preservation Board approvals, including for historic buildings or districts. Ask whether your property or proposed layout needs those reviews. Do not assume every rooftop application has identical requirements. Ask your installer to identify the permit applicant, document revisions, outstanding reviews, and how you will receive copies of issued permits. Outside city limits, confirm the corresponding requirements with your own town or village building department.

Create a second checklist for the utility application. Interconnection is the review of connecting the generating system to the utility network. It does not replace local permission for construction. National Grid’s New York system portal guidance explicitly treats other required permits as independent of interconnection. If your bill names National Grid, its getting-started guide describes the installer applying for the interconnection agreement and receiving utility approval before installation. Ask for the application reference and copies of the utility’s communications.

Ask your serving utility and installer to identify the review path for the proposed system, the design information needed, and any outstanding technical conditions. Who responds if the utility requests changes? Would a change of inverter, array size, or battery require another review? Who is responsible for any required network or metering work? Do not use a submitted application or a map as evidence of project approval. Keep each approval with the design version it covers, and ask how changes will be reflected in both the utility and municipal records.

Buffalo’s inspection divisions conduct inspections associated with building and electrical permits. Ask the City which building and electrical inspectors are assigned to your job, which stages they need to see, and who schedules them. Ask your contractor to keep inspection results, correction notices, and closeout documents available to you. A passed municipal inspection is not, by itself, permission to operate a system in parallel with the utility grid.

The New York standardized interconnection requirements, effective February 9, 2026, address verification testing and contractual and technical compliance separately. For its small-system process, operation follows satisfactory verification testing, subject to those requirements; final acceptance is a separate step. Ask the serving utility to confirm the exact authorization and testing requirements for your project before anyone energizes it. Do not treat a municipal inspection sticker or an installer’s completion message as that confirmation. Request the utility acceptance record and a clear handover explaining monitoring, shutdown instructions, warranties, and whom to contact about a fault.

Use NREL PVWatts to explore an estimated production scenario and compare the inputs with an installer’s model. Ask which location, system size, roof tilt, direction, and loss assumptions were entered. PVWatts warns that predictions depend on assumptions and do not capture site characteristics beyond its inputs. Its output is a model, not a roof survey or a guarantee of future generation. Ask the installer to explain differences between modeled output and the findings from your property assessment.

Billing treatment for your account remains unverified here. Ask the utility: Would this project receive net metering, Value Stack treatment, or another arrangement? Which tariff applies, how is exported electricity credited, and which charges remain? Ask how a battery or future change to the system would affect the answer. Then have the installer show those confirmed assumptions separately from its production estimate. Review the incentive guide for additional questions and keep proposed benefits separate from eligibility that has actually been confirmed. Neither a production model nor a quote establishes your tax eligibility or the future value of electricity.
