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 reduce electricity costs and help the environment by reducing your carbon footprint using renewable energy. Here are some key factors to consider when evaluating if a solar installer is reliable.
Confirm that your solar installer is properly licensed. This help guarantee that the work is done correctly using current best installation practices. 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.
Look at review platforms such as Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to find out what previous customers are saying about local solar installers. Reviews can give you an idea of a company’s trustworthiness and customer service. Be wary of companies lacking reviews or with predominantly negative feedback.
Get free, detailed quotes from at least three solar companies. A quote should describe all costs and identify the exact solar parts included. Comparing several quotes can help you find the option that best fits your budget.
Top-notch solar installations should come with strong workmanship and performance guarantees. A workmanship warranty covers installation defects, such as poor alignment, poor wiring, or cracks in the panels. A performance guarantee ensures a minimum energy output. Comprehensive warranties show that a solar company believes in its work.
Installing solar panels can help lower your electric bills over time. When evaluating the total price and value of solar panels, be sure to consider these factors.
The average Guilford homeowner will spend around $11,885 on a home solar system after federal tax refunds.

An estimate from a local solar provider will include costs for permit fees, labor, and preliminary work, and will account for your system's capacity, size, and panel type. Some homeowners prefer to lease their solar panels to reduce upfront costs.

A solar photovoltaic (PV) system can generate power to run any electric system or appliance in your home. More specifically, you can install a solar water heating system.
There are a number of advantages of home solar energy. You can qualify for tax benefits, save money, and reduce emissions. With the right storage equipment, solar panels can also provide you with additional energy security and offer some protection from power outages.
Yes, it's possible to use home solar energy alongside conventional power sources. In many areas, solar panels are designed to supplement your existing energy sources, meaning that you can reap the environmental benefits and savings of solar energy without having to completely switch over.
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, their rated capacity, and the average sunlight in your area. Guilford gets quite a bit of sunlight per day, so an average payback period could last up to 9.8 years per 5 kW of capacity.
While solar energy might not be the best performing choice for some in wet or dark areas, the latest generation of equipment and energy storage systems could increase your property's solar viability enough where you could 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.
Ultimately, the answer will depend on your specific situation. You'll be eligible for a federal tax credit of up to 30% of the system's cost, as well as state or local incentives depending on where you are. As for insurance, you'll need to let your insurer know about your new solar panels. Your premium may increase due to added property values, but you'll have peace of mind if a covered event happens to the system.
The best type of residential solar panel depends on your specific needs and goals. In most cases, monocrystalline solar panels are the most efficient for Guilford homes. However, if lowering cost is your top priority, then you may want to consider polycrystalline or thin-film solar panels. When selecting a solar company, make sure to ask about the different types of solar panels an installer offers and the benefits and drawbacks of each.
