How To Choose a Solar Company

Going solar can be a great way to reduce electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some crucial factors to consider when evaluating if a solar installer is trustworthy.

Check Licensing

Confirm that your solar installer is properly licensed. This helps ensure that the work is done properly using current best installation practices. In Missouri, it's purely up to cities and counties issue contracting licenses. However, all contractors must register with the Missouri Secretary of State.

Read Customer Reviews

Look at review platforms such as Google Reviews, the Better Business Bureau (BBB), and TrustPilot to find out what previous customers have to say about local solar installers. Reviews can give you an idea of a company’s dependability and customer service. Be cautious of companies with no reviews or with predominantly negative feedback.

Compare Multiple Quotes

Call 3–5 solar companies for free, itemized quotes. These quotes should outline all costs and list the solar equipment included. Reviewing multiple quotes helps identify the best option that fits your budget.

Ask About the Warranty

High-quality solar installations should have robust workmanship and performance guarantees. The workmanship warranty covers any installation issues like cracks in the panels, poor wiring, or poor alignment. The output guarantee ensures an energy generation baseline. Strong guarantees reflect a solar provider's faith in its installations.

Evaluate Financing and Incentives

Solar energy can help you lower electricity bills over time. Be sure to consider these aspects when considering the final cost and value of solar panels.

  • Look into utility rebates: Local power companies may have extra financial benefits to incentivize homeowners to go solar. Review the qualification rules and rebate amounts with your local provider to calculate your potential savings.
  • Research federal and state tax credits: A 26% federal tax credit on the full cost of solar systems is available through 2032. Many states also provide incentives. These credits can lead to substantial savings for solar buyers.
  • Compare system purchase options: Solar panels may be paid for outright or financed over time with loans or leases. Verify key financing details like annual percentage rate (APR), fees, payment schedule, and ownership implications when financing solar panels.

Cost of Solar Installation in Chesterfield

The cost of solar panels varies based on system capacity and the solar technology used. The typical Chesterfield solar array has a capacity of 7.2 kilowatts. Homeowners in the area can expect to pay approximately $3,370 per kilowatt; the average Chesterfield homeowners spends about $17,060 on a new solar array after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to reduce their upfront costs.) A personalized quote from a local solar provider will account for things like the panel type, capacity, and size of the planned system, and should include fees for labor, permit fees, and preliminary work.

Frequently Asked Questions About Solar in Chesterfield, MO

A solar photovoltaic (PV) array can generate power to run any electric appliance or system in your home. A more specific example is installing a solar heating system for your water.

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

It depends on your location and what type of panels you're installing. Since there's a moderate amount of snowfall in Chesterfield, your best time to get solar is in the spring and fall.

Yes, it's possible to use home solar energy alongside conventional power sources. In most parts of the country, solar panels are designed to supplement your existing energy sources, meaning that you can reap the savings and environmental benefits of solar energy without having to completely switch over.

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 Chesterfield, the average amount someone can save is $1,198 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system after the payback period concludes.

While solar energy might not be the best option for some in wet or dark areas, the latest generation of equipment and energy storage systems could increase your property's solar viability enough to 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. Keep 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.

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 houses in Chesterfield. However, if you're looking at a more frugal option, then you may want to consider polycrystalline or thin-film solar panels. When selecting a solar company, make sure to ask about the types of solar panels a company offers and the benefits and drawbacks of each.
