How To Choose a Solar Company

Adopting solar power lets homeowners lower utility bills while benefiting the planet 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.

Check Licensing

It's imperative that your solar installer has the proper licensing. This ensures that the work is done properly using the most up-to-date installation methods. 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 TrustPilot, the Better Business Bureau (BBB), Google Reviews, and other review sites to see what past customers have to say about local solar providers. Detailed reviews can help you assess a provider's trustworthiness and customer service. Stay away from companies with few or mainly poor reviews.

Compare Multiple Quotes

Get free, detailed quotes from at least three solar companies. A quote should outline all costs and identify the exact solar parts included. Looking at several quotes can help you find the best value for your budget.

Ask About the Warranty

Quality solar installations should have comprehensive workmanship and performance guarantees. The workmanship warranty covers any installation issues such as poor alignment, poor wiring, or cracks in the panels. The performance guarantee ensures a specific energy output level. Strong warranties indicate that a solar installer trusts its installations.

Evaluate Financing and Incentives

Installing solar panels can help lower your electric bills over time. When evaluating the total price and value of solar panels, be sure to consider these factors.

  • Look into utility rebates: More financial incentives might be available from local power companies looking to encourage homeowners to go solar. Contact your local utility provider to learn rebate values and eligibility rules, so you can calculate your possible savings.
  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states also offer incentives. These credits can lead to substantial savings for solar buyers.
  • Compare system purchase options: Homeowners can pay for solar panels outright or finance payments over time with loans or leases. Be sure to verify key details like payment schedule, annual percentage rate (APR), fees, and what ownership means when financing solar panels.

Frequently Asked Questions About Solar in Lake St. Louis, MO

Generally speaking, a solar photovoltaic (PV) array can be used to power any household system or appliance that uses electricity. In the simplest case, you can use a solar water heater.

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

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

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 Lake St. Louis amount to $1,171.

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. Lake St. Louis 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.

Your recommended maintenance will vary based on the type of solar panels you have. At a minimum, you should clean and inspect each panel once per season. Your solar installation company might offer comprehensive plans where they'll do the maintenance on your behalf.

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 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.

Some frequently-used types of home solar panels in Lake St. Louis include polycrystalline, thin-film and monocrystalline. Monocrystalline panels are balanced and efficient, while polycrystalline and thin-film panels pair good performance with greater upfront value. Talk with your local provider about which solar panels they work with.
