How To Choose a Solar Company

Putting solar panels on your roof could lower your electricity payments while helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when researching local solar installers are as follows.

Check Licensing

Verify that your solar installer is properly licensed. This ensures that the work is done properly using current best installation 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

Look at review platforms such as the Better Business Bureau (BBB), TrustPilot, and Google Reviews to find out what previous customers are saying about local solar installers. Reviews can give you an idea of a company’s reliability and customer service. Be wary of companies lacking reviews or with predominantly negative feedback.

Compare Multiple Quotes

Call 3–5 solar companies for free, itemized quotes. These quotes should explain all costs and specify the solar equipment included. Reviewing multiple quotes helps you find the option that aligns with 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 cracks in the panels, poor alignment, or poor wiring. The performance guarantee ensures a specific energy output level. Strong guarantees indicate that a solar installer has faith in its installations.

Evaluate Financing and Incentives

Going solar can help lower your energy expenses. Be sure to evaluate these aspects when determining the cost and value of solar panels.

  • Compare system purchase options: Homeowners may purchase solar panels outright or spread out payments over time with a lease or loan. Be sure to verify key details like annual percentage rate (APR), fees, payment schedule, and what ownership means when financing solar panels.
  • Research federal and state tax credits: A 26% federal solar tax credit on total system costs is available through 2032. Many states also offer incentives. These credits provide substantial savings for solar customers.
  • Look into utility rebates: Local electric providers may offer additional rebates to encourage homeowners to adopt solar panels. Check the eligibility rules and rebate values with your local power company to determine what your savings could be.

Frequently Asked Questions About Solar in Affton, 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.

There are many advantages of home solar energy. You can raise your property values, qualify for tax benefits, and save money. With the right storage equipment, solar panels can also provide you with additional energy security and offer some protection from power outages.

It depends on your home's location and the kind of panels you plan to use. Since there's a moderate amount of snowfall in Affton, your best time to install solar panels 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 Affton amount to $1,273.

Net metering is a type of "power purchase agreement." If your state or utility offers net metering, you can sell the solar energy you don't use to the grid. In return, they'll give you a credit on your power bill.

Although solar energy is a valuable option for many, it might not be ideal for homeowners in wet, dark areas. In these cases, a contractor might recommend other forms of renewable energy, such as wind or geothermal power, as a primary source. It is also important to speak to a qualified installer to determine if their solar system is compatible with the climate and environment of your area. Even if you choose a different form of renewable energy altogether, you'll still lower your emissions and could still qualify for distributed generation or other money-saving programs.

Solar panels are on par with other forms of renewable energy. Their maintenance costs are low and today's systems can generate and manage energy under more conditions.
