How To Choose a Solar Company

Installing solar panels can cut your electricity costs and help the environment by reducing your carbon footprint. When evaluating if a solar provider is right for you, consider these key factors.

Check Licensing

Make sure you hire a licensed solar installer. This help guarantee that the work is done correctly using current installation best practices. 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

Check Google Reviews, the Better Business Bureau (BBB), TrustPilot, and other review sites to see what past customers are saying about local solar providers. Detailed reviews can help you assess a provider's reliability and customer service. Avoid providers with few or mainly poor reviews.

Compare Multiple Quotes

Call three to five solar companies for free, itemized quotes. These quotes should explain all costs and specify the solar equipment included. Reviewing multiple quotes helps identify the best option that fits your budget.

Ask About the Warranty

Quality solar installations should have strong workmanship and performance guarantees. A workmanship warranty covers any installation defects (such as poor alignment, poor wiring, or cracks in the panels), while a performance warranty ensures a certain level of energy production. Strong warranties show that a company is confident in its work.

Evaluate Financing and Incentives

Solar energy can help you lower electricity bills over time. Be sure to consider these aspects when considering the final cost and value of solar panels.

  • Look into utility rebates: Local power companies may offer additional rebates to encourage homeowners to install solar panels. Check the eligibility rules and rebate values with your local utility provider to determine what your savings could be.
  • Compare system purchase options: Homeowners can pay for solar panels upfront or spread out payments over time with a loan or lease. Be sure to check key details like annual percentage rate (APR), fees, payment schedule, and what ownership means when financing solar panels.
  • Research federal and state tax credits: There’s a 26% federal tax credit available for the full cost of solar systems until 2032. Many states also provide incentives. The credits can result in significant savings for solar buyers.

Frequently Asked Questions About Solar in Smithtown, NY

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

With home solar panels, you can save money on your energy bill, lower your property's emissions, and gain additional energy independence.

It depends on your location and the kind of panels you plan to use. Since there's a moderate amount of snowfall in Smithtown, your best time to get solar is in the spring and fall.

Of course. The grid in Smithtown 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.

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

While solar energy might not be the best performing choice for some in dark or wet areas, the latest generation of equipment and energy storage systems could boost your property's solar viability enough to achieve a return on investment. A contractor could also recommend a different primary source of renewable energy like wind or geothermal to boost your generation.

Solar panels can be more efficient than other forms of renewable energy. They have inexpensive upkeep and today's systems can generate and manage energy under more conditions.
