How To Choose a Solar Company

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

Check Licensing

Confirm that your solar installer is properly licensed. This help guarantee that the work is done correctly 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 say about local solar companies. 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

Contact 3–5 solar companies to receive free, detailed quotes. Quotes should clearly explain all costs and list the exact solar components included. By comparing multiple quotes, you can identify the option that best fits your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Solar energy can help reduce your energy expenses. Be sure to consider these aspects when judging the cost and value of solar panels.

  • Compare system purchase options: Homeowners can pay for solar panels outright or spread out payments over time with a loan or lease. Be sure to check key details like annual percentage rate (APR), fees, payment schedule, and what ownership means when financing solar panels.
  • 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 learn rebate values and eligibility rules, so you can determine your possible savings.
  • Research federal and state tax credits: There’s a 26% federal tax credit available for total solar system costs until 2032. Many states also offer incentives. The credits can result in significant savings for solar buyers.

Cost of Solar Installation in Arnold

Solar panel costs vary based on your system's capacity and the solar technology used. The typical Arnold solar array has a capacity of 7.2 kilowatts. Homeowners in the area can expect to pay around $3,370 per kilowatt; the average Arnold homeowners spends about $16,950 on a new solar system 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 factors such as the panel type, size, and capacity of the planned system, and should include prices for permit fees, preliminary work, and labor.
