How To Choose a Solar Company

Installing solar panels can lower your electricity costs and help the environment by reducing your carbon footprint. When deciding if a solar provider is right for you, consider these key factors.

Check Licensing

It's imperative that your solar installer has the proper licensing. This help guarantee that the work is done properly using current installation best practices. In Missouri, it's the responsibility of counties and cities issue contracting licenses. However, all contractors must register with the Missouri Secretary of State.

Read Customer Reviews

Check review sites like TrustPilot, Google Reviews, 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 customer service. Use caution with companies that have no reviews or mostly negative ones.

Compare Multiple Quotes

Call three to five solar companies for free, itemized quotes. A quote should outline all costs and specify the solar equipment included. Reviewing multiple quotes helps you find the most cost-effective option for your budget.

Ask About the Warranty

Quality solar installations should include strong workmanship and performance guarantees. A workmanship warranty addresses any installation defects (such as cracks in the panels, poor wiring, or poor alignment), while a performance guarantee ensures a certain level of energy production. Strong warranties demonstrate a company's confidence in its work.

Evaluate Financing and Incentives

Solar panels can help decrease your electricity costs over time. When evaluating solar panel's cost and value, be sure to weigh these considerations.

  • Compare system purchase options: Homeowners may purchase solar panels upfront or spread out payments over time with a loan or lease. Be sure to check key details like fees, payment schedule, annual percentage rate (APR), and what ownership means when financing solar panels.
  • Research federal and state tax credits: There’s a 26% federal tax credit available for total solar system costs until 2032. Many states also provide incentives. The credits can add up to significant savings for solar buyers.
  • Look into utility rebates: More discounts might be available from utility companies looking to encourage homeowners to switch to solar power. Contact your local utility provider to find out rebate values and eligibility rules, so you can calculate your possible savings.

Frequently Asked Questions About Solar in Dardenne Prairie, MO

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 heating system for your water.

With home solar panels, you can recoup the cost of the system over time, lower your home's carbon footprint, and gain additional energy independence.

Generally speaking, your energy bills will decrease significantly after you install solar panels. This is because you're using the energy you generate for free rather than buying it from your power company. In Dardenne Prairie, the average amount someone can save is $1,171 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system after the payback period concludes.

Your payback period is the time to earn a net profit from 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. Dardenne Prairie gets quite a bit of sunlight per day, so an average payback period could last up to 14.6 years per 5 kW of 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. A majority of solar contractors in the Dardenne Prairie area offer multipoint maintenance plans to help you keep your panels healthy and make the most of your system.

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 boost 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 inform your insurance company 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.
