Selecting the right home solar installation company in St. Louis, MO, is essential to ensure top-quality service, reliable products, and a seamless installation process.
With numerous solar installers in the area, understanding the key factors that set reputable companies apart can help you make a well-informed choice.
This guide highlights important considerations, such as certifications, customer reviews, financing options, and more, to help you find the best solar provider in St. Louis, MO, for your needs.
1. Verify Licensing and Certifications
When evaluating a solar panel installer in St. Louis, MO, check for proper licensing and certifications. Reputable solar experts should hold certifications from recognized industry organizations, such as:
- North American Board of Certified Energy Practitioners (NABCEP): A leading certification for solar professionals, indicating extensive training and expertise.
- Missouri State Electrical License: Required for performing electrical work on solar installations.
- Better Business Bureau (BBB) Accreditation: Demonstrates a commitment to ethical business practices.
These credentials ensure that the solar installation company follows industry standards and safety guidelines.
2. Assess Experience and Track Record
Not all solar companies have the same level of expertise. Choose an installer with a proven history of successful solar panel installations in St. Louis, MO. Key factors to consider include:
- Years in Business: Companies with several years of experience are more likely to provide reliable service and honor warranties.
- Number of Installations: A high number of completed projects indicates proficiency in handling various installation scenarios.
- Expertise with Local Permits and Regulations: Missouri has specific solar permitting requirements, and experienced solar installers are familiar with the process.
3. Check Customer Reviews and Testimonials
Customer feedback provides valuable insights into a company’s reliability and service quality. When researching the best solar companies, look for:
- Online Reviews: Platforms like Google, Yelp, and BBB offer real customer experiences.
- Testimonials on Company Websites: While often positive, they can still highlight key strengths.
- References from Past Customers: Reputable installers should be willing to provide contact information for satisfied clients.
Look for a company with consistently high ratings, especially regarding installation quality, customer service, and warranty support.
4. Compare Financing Options and Incentives
Investing in residential solar panels in St. Louis, MO, can be costly, but various financing options can make it more affordable. A good solar installer should offer:
- Cash Purchase: Offers the highest long-term savings but requires upfront payment.
- Solar Loans: Financing options that allow homeowners to pay over time while benefiting from solar savings.
- Solar Leases or Power Purchase Agreements (PPAs): Some companies provide leasing options with lower initial costs but may have limitations on savings.
Additionally, inquire about available solar incentives in Missouri, such as:
- Federal Solar Tax Credit (ITC): Allows homeowners to deduct 30% of installation costs from federal taxes.
- Missouri Solar Rebates and State Tax Incentives: Some local utilities offer rebates for solar energy systems.
- Net Metering Programs: Enables homeowners to earn credits by sending excess solar energy back to the grid.

5. Evaluate Equipment Quality and Warranties
Not all inverters and solar panels in St. Louis, MO, are created equal. The best solar companies use high-quality equipment with strong warranties. Consider:
- Panel Efficiency and Brand Reputation: Leading brands such as SunPower, LG, and REC offer high-efficiency solar panels.
- Inverter Technology: String inverters, microinverters, and power optimizers impact system performance and reliability.
- Warranty Coverage: Look for a solar panel installer in St. Louis, MO, that provides:
- Panel Warranty: Typically 25 years
- Inverter Warranty: Ranges from 10 to 25 years
- Workmanship Warranty: Covers installation quality, usually lasting 5-10 years
6. Inquire About Installation Processes and Timelines
A smooth installation process depends on efficient project management. Ask potential solar installers about:
- Site Evaluation and System Design: A thorough assessment ensures a customized solar system for your energy needs.
- Permit and Utility Approval: Experienced installers handle necessary permits and approvals.
- Installation Timeline: Standard installations typically take 1-3 days, but the entire process (including permitting) can take weeks.
7. Consider Local Expertise and Support
Working with a St. Louis-based solar company ensures local knowledge and ongoing support. Benefits include:
- Familiarity with Missouri Climate: Local experts design systems suited to regional weather conditions.
- Quick Response for Maintenance and Repairs: Choosing a local installer ensures prompt service if issues arise.
- Strong Community Presence: Locally operated solar experts are more accountable to their community.
8. Get a Detailed Quote and Review the Proposal
To ensure the best decision, obtain a comprehensive quote from your selected solar installer. When reviewing the proposal, pay attention to:
- Total System Cost: Includes equipment, labor, permits, and additional fees.
- Estimated Energy Savings: Project potential savings over time.
- Payback Period: The time it takes to recover the initial investment.
- Warranty Terms: Ensure comprehensive coverage for system components and installation.
9. Customer Service and After-Sales Support
A reputable solar company provides excellent customer service before, during, and after installation. Look for:
- Dedicated Support Team: Ensures clear communication and assistance.
- Monitoring Tools: Many companies offer mobile apps to track solar performance.
- Ongoing Maintenance Services: Includes panel cleaning and system check-ups.
10. Choose a Solar Company with Roofing Expertise
Selecting a solar installation company that also provides roofing services can be a major advantage. Since in St. Louis, MO, solar panels are mounted directly onto the roof, working with a company experienced in both solar and roofing ensures:
- Proper Roof Assessment: A dual-service provider can evaluate roof conditions before installation, preventing unexpected issues that could delay the project.
- Seamless Roof Repairs or Replacement: If the roof needs repairs or replacement, handling both services through one company streamlines the process and reduces costs.
- Enhanced Warranty Coverage: Companies offering both solar and roofing services often provide warranties that cover both installations, ensuring long-term protection.
- Optimized System Longevity: A well-maintained roof extends the life of the solar system, preventing premature issues caused by structural weaknesses.
