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:
Adopting solar power lets homeowners lower utility bills while helping the environment by reducing your carbon footprint using clean energy. If you’re evaluating if you want to go solar, consider these key factors for choosing an installer.
Confirm that your solar installer is properly licensed. This ensures that the work is done properly using the most up-to-date installation methods. While electricians and plumbers in Colorado have state-issued licenses from the Colorado Electrical Board or Colorado State Plumbing Board, the state's unique home-rule structure means counties and cities can issue solar contracting licenses if they choose.
Check Google Reviews, TrustPilot, the Better Business Bureau (BBB), and other review sites to see what past customers have to say about local solar installers. Detailed reviews can help you evaluate a provider's integrity and customer service. Avoid providers with few or mainly poor reviews.
Contact at least three solar companies for free, detailed quotes. Quotes should clearly explain all costs and list the exact solar components included. By comparing multiple quotes, you can identify the option that best fits your budget.
Top-notch solar installations should come with strong workmanship and performance warranties. A workmanship warranty covers installation issues, such as poor alignment, poor wiring, or cracks in the panels. A performance guarantee ensures a minimum energy output. Comprehensive guarantees indicate that a solar company believes in its work.
Solar can help you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.
The cost of home solar panels in Derby will depend on several factors, including the area and generating capacity of your panel array and the type of panels you'll use.

2015 Large RFP Program: Generally speaking, a solar photovoltaic (PV) system 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. There are a number of advantages of home solar energy. You can reduce emissions, raise your property values, and qualify for tax benefits. With the right storage equipment, solar panels can also give you additional energy security and offer some protection from power outages. Of course. The grid in Derby 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 Derby amount to $1,060. Your payback period is the time to achieve an ROI on your solar panels. It will vary based on the average sunlight in your area, the rate your utility charges per kilowatt of power, and their rated capacity. Derby has extremely high daily sunlight levels, so you could recoup your investment in as little as 13.6 years per 5 kW of rated capacity. The answer ultimately depends on your specific situation. You can take advantage of 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 most common types of home solar panels in Derby include monocrystalline, polycrystalline and thin-film. 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 the types of solar panels they work with.
