How To Choose a Solar Company

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

Check Licensing

It's important to hire a licensed solar installer. This ensures 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

Check consumer review platforms like TrustPilot, the Better Business Bureau (BBB), and Google Reviews to see feedback from past customers about local solar companies. Detailed reviews can help you evaluate a company's dependability and level of service. Use caution with installers that have very few reviews or mostly negative ones.

Compare Multiple Quotes

To find a solar installer that works with your budget, ask for free, detailed quotes from three to five providers. The quotes should outline all costs and list the solar equipment included. Looking at several quotes helps you identify the most cost-effective option.

Ask About the Warranty

Top-notch solar installations should have strong workmanship and performance warranties. A workmanship guarantee covers installation issues, such as cracks in the panels, poor alignment, or poor wiring. A performance warranty ensures a minimum energy output. Comprehensive warranties indicate that a solar company believes in its work.

Evaluate Financing and Incentives

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

  • Look into utility rebates: Some energy providers may provide additional discounts to encourage homeowners to install solar panels. Check the qualification rules and rebate amounts offered by your local electric utility to determine your potential savings.
  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states offer incentives, too. The 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. Check key financing details like payment schedule, fees, annual percentage rate (APR), and ownership implications when choosing to finance solar panels.

Cost of Solar Installation in Eureka

The cost of solar panels varies based on system capacity and the solar technology used. The average solar system in Eureka has a capacity of 7.2 kilowatts. Homeowners in the area should expect to pay approximately $3,370 per kilowatt; the average Eureka homeowners spends roughly $17,005 on a new solar array after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to lower their upfront costs.) A personalized quote from a local solar provider will account for things like the capacity, size, and panel type of the planned system, and should include costs for labor, preliminary work, and permit fees.

Frequently Asked Questions About Solar in Eureka, MO

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

With home solar PV, you can recoup the cost of the system over time, lower your property's emissions, and be better prepared if there's an outage to the local grid.

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

Absolutely. The grid in Eureka 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 recommended maintenance will vary based on the type of solar panels you have. With any system, you should clean and inspect each panel every three months. Your solar energy company might offer comprehensive plans where they'll do the maintenance for you.

While solar energy is a great 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.

Absolutely. Solar panels exist independently from the power grid in Eureka 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.
