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:
Putting solar panels on your roof could lower your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.
It's important to hire a licensed solar installer. This help guarantee that the work is done properly using the most up-to-date installation methods. In Connecticut, a journeyman 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 sign up with the state's Clean Energy Fund, so that their customers can earn incentives.
Check review sites like Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to see customer feedback about local solar companies. Detailed reviews can help you assess a company's dependability and level of service. Use caution with providers that have very few reviews or mostly negative ones.
Call 3–5 solar companies for free, itemized quotes. These quotes should explain all costs and list the solar equipment included. Reviewing multiple quotes helps identify the option that aligns with your budget.
High-quality solar installations should include robust workmanship and performance warranties. The workmanship warranty covers any installation issues like cracks in the panels, poor alignment, or poor wiring. The output warranty guarantees an energy generation baseline. Strong guarantees reflect a solar provider's confidence in its installations.
Solar energy can help decrease your electric bills over time. When weighing the total price and value of solar panels, be sure to consider these factors.
The cost of home solar panels in Derby varies depending on several factors, including the area and generating capacity of your panel array and the type of panels you'll use. Generally speaking, a typical solar energy system costs $3,750 per kilowatt, not including preliminary work, permit fees, or labor. Most solar systems in Derby are 4.5 kilowatts, and the typical Derby homeowners spends $11,885 after accounting for federal tax refunds.

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 heater.
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 the kind of panels you plan to use. Since there's a moderate amount of snowfall in Derby, your best time to install solar panels is in the spring and fall.
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, which means you can reap the savings and environmental benefits that come from using solar energy without having to completely switch over.
Your payback period is the time to achieve an ROI on your solar panels. It will vary based on their rated capacity, the average sunlight in your area, and the rate your utility charges per kilowatt of power. Derby 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.
Net metering is a power purchasing policy that allows solar energy system owners to receive bill credits or payments for the amount of energy they put back into the grid. It's available in most states and is a great way to reduce energy costs.
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 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.
