How To Choose a Solar Company

Going solar can be a great way to lower electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some key factors to consider when evaluating if a solar installer is trustworthy.

Check Licensing

Verify that your solar installer is properly licensed. This help guarantee that the work is done properly using the most up-to-date installation methods. New York regulators do not issue licenses to contractors, so you should check with your city or county government for its specific regulations and requirements.

Read Customer Reviews

Look at review platforms such as Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to find out what previous customers have to say about local solar companies. Reviews can give you an idea of a company’s reliability and customer service. Be cautious of companies with no reviews or with predominantly negative feedback.

Compare Multiple Quotes

Contact 3–5 solar companies to receive free, detailed quotes. Quotes should clearly outline all costs and specify the exact solar components included. By comparing multiple quotes, you can identify the best value based on your budget.

Ask About the Warranty

High-quality solar installations should include robust workmanship and performance guarantees. The workmanship guarantee covers any installation issues like poor wiring, cracks in the panels, or poor alignment. The output guarantee ensures an energy generation baseline. Strong guarantees reflect a solar provider's confidence in its installations.

Evaluate Financing and Incentives

Solar energy can help reduce your electricity costs in the long run. When weighing solar panel's cost and value, be sure to consider these considerations.

  • Look into utility rebates: Local power companies may have extra financial benefits to motivate homeowners to go solar. Review the eligibility criteria and rebate amounts with your local provider to calculate your potential savings.
  • Research federal and state tax credits: A 26% federal solar tax credit on the full system cost is available through 2032. Many states also offer incentives. These credits provide substantial savings for solar buyers.
  • Compare system purchase options: Homeowners can pay for solar panels outright or finance payments over time with a loan or lease. Be sure to check key details like payment schedule, annual percentage rate (APR), fees, and what ownership means when financing solar panels.

Frequently Asked Questions About Solar in Brookhaven, NY

Generally speaking, a solar photovoltaic (PV) system can be used to power any household appliance or system that uses electricity. In the smallest case, you can use a solar water heater.

With home solar energy, you can recoup the cost of the system over time, lower your property's emissions, and be better prepared if there's an outage to the local grid.

Absolutely. The grid in Brookhaven already uses a large share of renewable energy sources, and you may be able to sell your excess generated energy to your utility for additional cost savings.

Your installer can give you an estimate of what your energy bills will look like after you install solar panels. Generally, your energy bills will decrease significantly because you'll be using energy from the sun for free, instead of buying energy from the utility company. The average annual savings in Brookhaven amount to $895.

Your payback period is the time to earn a net profit from your solar panels. It will vary based on the rate your utility charges per kilowatt of power, the average sunlight in your area, and their rated capacity. Brookhaven gets quite a bit of sunlight per day, so an average payback period could last up to 11.1 years per 5 kW of capacity.

The specific types of maintenance you need will depend on the type of panels you're using. Regardless of type, you should clean your panels regularly and inspect them for damage. Full-service solar contractors in the Brookhaven area offer multipoint maintenance plans to help you keep your panels healthy and make the most of your system.

Net metering is a type of "power purchase agreement." If your utility or state offers net metering, you can return the solar energy you don't use to the grid. In return, they'll give you a credit on your power bill.

The best type of residential solar panel will depend on your specific needs and goals. Generally, monocrystalline solar panels are the most efficient for homes in Brookhaven. However, if you're looking at a more frugal option, then you may want to consider thin-film or polycrystalline solar panels. When you're choosing a contractor, make sure to ask about the brand names and models of solar panels an installer offers and the benefits and drawbacks of each.
