1. Confirm the utility and your starting point
Con Edison serves New York City and Westchester County, according to its company information. Start with the utility name on your own electricity bill rather than assuming a service-area list identifies your provider. If the bill names another utility, ask that utility which solar interconnection process applies. Keep account details for a direct conversation with your chosen installer; a general research email does not need your full account number.
Before comparing proposals, write down what you want to understand: electricity use, ownership options, roof work, or backup power. Gather recent bills and note any planned changes in household electricity use. Ask each company how those assumptions affect its proposed system. Solar Panels Yonkers provides information and installer matching; independent companies evaluate the property and offer their own contracts. A request here does not guarantee a match or a particular project outcome.
2. Ask for a roof and electrical assessment
Ask the installer how it will evaluate roof age, remaining roof life, structural capacity, roof direction and shade. Who will inspect the roof, and who will document whether it can support the proposed equipment? If repairs are recommended, ask whether they should precede the solar work and who would remove and reinstall panels later. These are project questions, not a claim that every Yonkers home needs roof repairs.
For the electrical review, ask whether the existing service panel has adequate capacity for the design. Would the work require a panel replacement, service change, new wiring or a different equipment location? Ask who evaluates those needs and which items are included in the written scope. Request an explanation of unresolved items before treating a preliminary proposal as a final design. Do not assume that a photograph or an online estimate resolves these questions.
3. Start the City permit track
The City of Yonkers Forms & Permits page lists the Unified Solar Permit Application among Department of Housing and Buildings applications and says department applications can be filed online. Start with that department for the building and electrical permit process. The City links its online filing portal from that page. Ask the department which application route and supporting plans apply to your residential rooftop project, and ask your installer who will submit and track them.
The solar permit eligibility checklist asks whether the installation avoids Landmarks Preservation Board review and does not need a zoning variance. Those are checklist conditions, not a blanket exemption from historic or zoning review. Ask the City whether your property and design meet the expedited route or need another review. Confirm who issues the building approval for your specific scope and what remains outstanding before scheduling work.
4. Open the separate Con Edison track
Con Edison identifies PowerClerk as its online interconnection application route in its application guidance. Its small-project overview describes application submission, utility review and final acceptance. This is the utility connection track, separate from City permit paperwork. Ask your installer to identify the correct application for the proposed system and show you how to follow its status. Ask Con Edison what authorization is needed before each stage of work.
The linked DG documentation checklist identifies a completed PowerClerk application. Use the current application guidance to ask which supporting documents, tests and approvals your design needs; do not treat an older checklist as a complete project-specific instruction. Request clarification of utility conditions or design changes before accepting a revised proposal. Keep separate status records and responsibilities for the permit and interconnection applications.
5. Compare production and bill assumptions
PVWatts estimates photovoltaic energy production. Use it as a model for discussing a proposal, not as a roof survey or a promise of output. Ask the installer to show its estimate inputs and explain how it assessed orientation, shade and losses. Keep a copy of the assumptions so differences between proposals can be discussed without treating the largest production estimate as automatically the best design.
Con Edison’s solar information page says customers can earn bill credits from solar electricity. That alone does not establish your credit calculation. Ask Con Edison and the installer: Will this account use net metering or Value Stack? Which tariff and enrollment conditions apply? How are exported electricity, remaining charges and unused credits handled? We have not verified an account-specific billing treatment here. Request a written explanation rather than assuming generation erases the entire bill.
6. Coordinate installation and inspections
Before scheduling installation, ask the installer to list received approvals, remaining conditions and who coordinates inspection requests. The City’s Building On-Line Filing guidance says City electrical inspectors monitor and inspect electrical permits. Ask the Department of Housing and Buildings which building inspections and completion documents your project also requires, who performs them and how they are requested. We do not publish an unverified inspection sequence for every roof.
Keep the City inspection record separate from the utility record. A passed City inspection is not Con Edison’s permission to operate: its application guidance identifies utility final acceptance as a separate approval. Ask Con Edison which written notice authorizes operation of your system, and ask the installer to provide that notice before normal operation. If someone says the project is approved, clarify whether that means City permitting, an inspection result, utility design review or final acceptance.
7. Keep the closeout record and follow up
Ask for the final equipment list, warranties, inspection records, utility acceptance and monitoring instructions together. Who should you contact about a roof issue, an inverter alert or a billing question? Ask the installer to demonstrate monitoring and explain what to do if reported production differs from its estimate. Compare the assumptions and observation period before drawing conclusions from a short snapshot.
Plan around dependencies rather than a promised number of days or weeks: clarify the design, track City and utility requirements, resolve outstanding conditions, document inspections and confirm authorization to operate. Ask for an updated sequence when the scope changes. Review incentive assumptions separately on our incentives page and confirm current eligibility with the relevant authority. Keep the original proposal and revisions so changes in equipment, responsibilities and assumptions remain easy to trace.
