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:
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 crucial factors to consider when deciding if a solar installer is trustworthy.
Make sure you hire a licensed solar installer. This help guarantee that the work is done correctly using the most up-to-date installation methods. In Connecticut, a journeyman who meet minimum experience requirements can take an exam to become a licensed solar PV or thermal contractor. Once they're licensed, they'll need to sign up with the state's Clean Energy Fund, so that their customers can earn incentives.
Check the Better Business Bureau (BBB), Google Reviews, TrustPilot, and other review sites to see what past customers are saying about local solar companies. Detailed reviews can help you assess a provider's integrity and customer service. Avoid providers with few or mainly poor reviews.
Contact three to five solar companies to receive free, detailed quotes. Quotes should clearly explain all costs and specify the exact solar components included. By comparing multiple quotes, you can identify the most cost-effective option for you.
High-quality solar installations should have robust workmanship and performance guarantees. The workmanship warranty covers any installation issues like cracks in the panels, poor alignment, or poor wiring. The output guarantee ensures an energy generation baseline. Strong guarantees reflect a solar provider's confidence in its installations.
Going solar can help decrease your electric bills over time. When considering the total price and value of solar panels, make sure to consider these factors.
In Greenwich, solar panels cost an average of $3,750 per kilowatt, with an average system size of 4.5 kilowatts. The typical Greenwich homeowner spends $11,749 on their solar array after federal tax refunds. An estimate from a local provider will consider additional information based on your desired system's panel type, size, required preliminary work, and capacity. In some cases, homeowners may prefer leasing solar panels to reduce upfront costs.

A solar photovoltaic (PV) array can generate power to run any electric system or appliance in your home. If you don't want to use solar power for your entire home, you can install a solar water heating system.
There are many benefits to home solar energy. You can qualify for tax benefits, save money, and raise your property values. With the right storage equipment, solar panels can also offer you further energy independence and offer some protection from power outages.
Yes. The grid in Greenwich 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 Greenwich amount to $1,141.
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.
Yes, solar panels can still supply you with energy during a grid outage. To ensure that your solar system can keep working during a power outage, make sure to choose a quality solar provider that offers battery backup systems or emergency generators.
The most common types of home solar panels in Greenwich include polycrystalline, monocrystalline and thin-film. Monocrystalline panels are balanced and efficient, while polycrystalline and thin-film panels pair good performance with greater upfront value. Ask your local provider about which solar panels they work with.
