Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Installing solar panels can reduce 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.
Verify that your solar installer is properly licensed. This helps ensure that the work is done correctly using current best installation practices. In Connecticut, a professional meeting minimum experience requirements can take an exam to become a licensed solar PV or thermal contractor. Once they're licensed, they'll need to enroll with the state's Clean Energy Fund, so that their customers can earn incentives.
Check the Better Business Bureau (BBB), TrustPilot, Google Reviews, and other review sites to see what past customers have to say about local solar companies. Detailed reviews can help you evaluate a provider's integrity and customer service. Be wary of companies with few or mainly poor reviews.
To find a solar installer that fits your budget, ask for free, detailed quotes from 3–5 providers. The quotes should outline all costs and list the solar equipment included. Comparing several quotes helps you identify the most cost-effective option.
Quality solar installations should come with strong workmanship and performance guarantees. A workmanship guarantee covers any installation defects (such as poor alignment, cracks in the panels, or poor wiring), while a performance warranty ensures a certain level of energy production. Strong guarantees show that a company is confident in its work.
Installing solar panels can help reduce your electric bills over time. When weighing the total price and value of solar panels, be sure to consider these factors.
In New Haven, solar panels cost an average of $3,750 per kilowatt, with an average system size of 4.5 kilowatts. The typical New Haven homeowner spends $11,885 on their solar array after federal tax refunds. An estimate from a local provider will take into account additional information based on your desired system's size, required preliminary work, panel type, and capacity. In some cases, homeowners may prefer leasing solar panels to reduce upfront costs.

Generally speaking, a solar photovoltaic (PV) system can be used to power any household system or appliance 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 home's carbon footprint, and be better prepared if there's an outage to the local grid.
It depends on where you live and what type of panels you're installing. New Haven can experience long, hard winters, so we recommend installing your system in the springtime to maximize your generation for the year.
Yes. The grid in New Haven 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.
Generally speaking, your energy bills will decrease significantly after you install solar panels. This is because you're using the energy you generate for free rather than buying it from your power company. In New Haven, the average amount someone can save is $1,289 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system once the payback period passes.
Net metering is a type of "power purchase agreement." If your state or utility offers net metering, you can send the solar energy you don't use to your provider. In return, they'll give you a credit on your power bill.
The most common types of home solar panels in New Haven include thin-film, polycrystalline and monocrystalline. Monocrystalline panels are balanced and efficient, while thin-film and polycrystalline panels pair good performance with greater upfront value. Talk with your local provider about which solar panels they work with.
