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 key factors to consider when deciding if a solar installer is reliable.
Verify that your solar installer is properly licensed. This ensures that the work is done correctly using current best installation practices. While electricians and plumbers in Colorado have state-issued licenses from the Colorado Electrical Board or Colorado State Plumbing Board, counties and cities can issue solar contracting licenses if they choose.
Look at review platforms such as Google Reviews, TrustPilot, and the Better Business Bureau (BBB) to find out what previous customers say about local solar providers. Reviews can give you an idea of a company’s trustworthiness and customer service. Be wary of companies with no reviews or with predominantly negative feedback.
Get free, detailed quotes from at least three solar companies. A quote should list all costs and identify the solar parts included. Comparing several quotes can help you find the best value for your budget.
Quality solar installations should include strong workmanship and performance warranties. A workmanship warranty covers any installation defects (such as poor alignment, poor wiring, or cracks in the panels), while a performance warranty ensures a certain level of energy production. Strong guarantees show that a company is confident in its work.
Switching to solar power can help reduce your energy expenses over time. Be sure to consider these aspects when determining the cost and value of solar panels.
In Thornton, solar panels cost an average of $3,980 per kilowatt, with an average system size of 5.2 kilowatts. The typical Thornton homeowner spends $14,488 on their solar array after federal tax refunds. An estimate from a local provider will factor in additional information reflecting your desired system's capacity, size, required preliminary work, and panel type. In some cases, homeowners may prefer leasing solar panels to reduce upfront costs.

2015 Large RFP Program: Incentive Amount: Air Sealing: $300-$500 Incentive Type: Property Tax Incentive Incentive Amount: Varies (local option) A solar photovoltaic (PV) array 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 benefits to home solar energy. You can reduce emissions, raise your property values, and save money. With the right storage equipment, solar panels can also provide you with further energy independence and offer some protection from power outages. Yes. The grid in Thornton 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 payback period is the time to achieve an ROI on your solar panels. It will vary based on their rated capacity, the rate your utility charges per kilowatt of power, and the average sunlight in your area. Thornton has extremely high daily sunlight levels, so you could recoup your investment in as little as 13.4 years per 5 kW of rated capacity. The type of solar panels you have will have specific maintenance steps to follow. Regardless of type, you should inspect your panels for damage and clean them regularly. Many solar contractors in the Thornton area offer low-cost maintenance plans to help you make the most of your panels and keep them healthy for as long as possible. While solar energy might not be the best option 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. Of course. Solar panels don't depend on the grid to work and will continue to generate power even if the grid is having problems. Bear in mind, however, that a solar system won't take you through a nighttime outage if you don't have a storage system. Your contractor can discuss some economical options to keep your home's power access reliable through the worst conditions, including battery backups or an emergency generator. Loading map...
