Embarking on your solar journey is an exciting step toward energy independence and environmental stewardship. Selecting the perfect solar installer is one of the most critical decisions you’ll make in this process.
A quality installation ensures decades of reliable clean energy, while poor workmanship can lead to costly repairs, safety issues, and diminished returns on your investment.
Solar Insure has dedicated nearly 20 years to reviewing, underwriting, and certifying contractors who meet our high standards of professionalism. With experience working with over 500 solar installers in that time, we’ve gained deep insight into what distinguishes the most successful installers from those that fall short.
By understanding the reasons behind the success stories—and the failures—we’ve developed rigorous guidelines to help homeowners like you make informed, confident decisions.
We’ve compiled 20 essential tips for selecting the right solar installer to guide you in this critical choice. These guidelines will help you find a contractor who exceeds industry standards, setting you up for a truly successful solar experience.
1. Company Years in Business
Experience matters. Look for a contractor with a proven track record in the solar industry. Companies that have been active for several years have navigated the complexities of solar installations and established relationships with suppliers and manufacturers. Longevity often reflects reliability, stability, and a history of customer satisfaction.
Note: Longevity is also tied to the viability of their workmanship warranty. A company that is only 3 years old but offers a 25-year warranty may be less desirable than a company with 15 years of experience offering a 10-year warranty. The longer-established company is more likely to be around to honor their warranty.
2. Leadership Team Years of Industry Experience
The expertise of a company’s leadership team significantly influences the quality of service you receive. Investigate how many years the owners and executives have worked in the solar sector. Leaders with extensive industry experience are more likely to be knowledgeable about the latest technologies, best practices, and component changes, ensuring your installation is efficient and compliant.
Tip: Companies whose leadership has a strong construction background may be more beneficial than those led by individuals with only sales experience. You can typically find further information on the ownership within the About page of the company website or on LinkedIn.
3. Licenses and Certifications
Verify that the contractor holds all the required licenses to operate in your state and locality. Depending on regional regulations, this may include an electrical contractor’s license or a general contractor’s license. Additionally, look for certifications from reputable organizations like the North American Board of Certified Energy Practitioners (NABCEP). Such certifications indicate a high level of training, expertise, and adherence to industry standards.
For instance, in CA, a solar company may have one or a combination of several different licenses, including C-46 Solar, C-10 Electrical, or B license.
State Licensing Resources:
- California: Contractors State License Board (CSLB)
- Texas: Texas Department of Licensing and Regulation
- Florida: Department of Business and Professional Regulation
- New York: Division of Licensing Services
- Pennsylvania: Home Improvement Consumer Protection Act
- Illinois: Department of Financial and Professional Regulation
- Arizona: Arizona Registrar of Contractors
- Nevada: Nevada State Contractors Board
- New Mexico: New Mexico Construction Industries Division
- Massachusetts: Home Improvement Contractor Registration
4. Legal Proceedings or Sanctions
A contractor’s legal history can provide valuable insights into their business practices.
Research any past or ongoing legal proceedings, lawsuits, or sanctions. A clean legal record suggests the contractor operates ethically and complies with industry regulations, reducing the risk of potential issues affecting your project.
5. Compliance Violations
Compliance with industry regulations is non-negotiable for a safe and effective solar installation. Investigate whether the contractor has had any regulatory compliance violations, such as fines or penalties from government agencies. Compliance violations can indicate negligence or a disregard for industry standards, which could compromise the safety and legality of your installation.
Ensure the contractor complies with all local, state, and federal regulations related to solar installations. This includes building codes, electrical codes, and zoning laws. Non-compliance can lead to fines, delays, or even the removal of your system.
Tip: You can check for violations through your local contractor license boards.
6. References and Performance Data
When evaluating a solar provider, ask for references from previous customers in your area. Speaking with past clients can give you a candid perspective on the customer experience, including insights into the quality of service, communication, and overall satisfaction with the installation. A provider willing to connect you with local references demonstrates confidence in their work and prioritizes transparency.
In addition to references, consider requesting actual production data from similar installations in your area. Comparing expected versus actual production can reveal how accurately the provider models system performance and if their installations consistently meet expectations. This data helps ensure you choose a provider with a proven track record for reliable, high-performing installations.
7. Customer Google & BBB Reviews
Online reviews offer firsthand accounts of customer experiences. Check the contractor’s Google reviews to gauge overall satisfaction levels. Pay attention to comments about workmanship, professionalism, communication, and post-installation support. Consistently positive reviews are a strong indicator of reliable service.
The Better Business Bureau (BBB) tracks complaints and resolutions between consumers and businesses. Reviewing a contractor’s BBB profile can reveal patterns in customer complaints and how the contractor addresses them. A high BBB rating and a low number of unresolved complaints are good signs of trustworthiness.
8. Sales Team Structure
When selecting a solar provider, it’s important to recognize that some companies operate as sales dealers, while others handle installations directly. Sales dealers often partner with third-party installers, and the level of connectivity between the sales team and the installer can vary widely. To ensure a seamless experience, homeowners should ask about the relationship between the salesperson and the installer. A strong, transparent partnership can lead to smoother communication and better service.
Additionally, prioritize working with sales representatives focusing on education over sales tactics. A knowledgeable rep committed to helping you understand your options and make informed choices is invaluable in decision-making. Educated homeowners have empowered homeowners, leading to higher satisfaction and long-term success with their solar systems.
9. Insurance Status
Request proof of the contractor’s insurance coverage, including general liability and workers’ compensation policies. Adequate insurance protects you from liability in case of property damage or injuries during the installation process. It also reflects the contractor’s professionalism and commitment to safety.
Reminder: Ask your solar installer to name you as an Additional Insured on their general liability policy. Also, don’t forget to add the solar installation to your homeowner’s insurance policy once the installation is completed.
10. Local Expertise
A solar contractor’s local experience is an important factor that impacts the success of your solar installation. This local expertise translates into tangible benefits for homeowners, including faster project completion, more accurate cost estimates, and fewer unexpected complications. Local contractors can navigate utility interconnection requirements efficiently, maximize available incentives, and provide quick response times for maintenance or emergencies.
Their understanding of regional energy consumption patterns and utility rates allows them to optimize system design for maximum ROI, while their established presence ensures reliable long-term support and warranty service. By choosing a contractor with local experience, homeowners invest in immediate project success and sustained system performance, backed by a partner who understands and can effectively address their specific region’s unique challenges and opportunities.
Expert Tip: Ask your solar installer of choice if they are headquartered in your state. Or do they have an established branch in the area? How long has it been established? What is the long-term commitment to servicing the area?

11. Labor & Subcontractor Usage
Managing labor and subcontractor relationships is another factor in solar installation quality and long-term system performance. Understanding whether contractors use in-house teams or subcontractors provides insight into their quality control processes and accountability standards.
While in-house teams often offer advantages like direct training, consistent quality control, and clear accountability, qualified subcontractors can bring specialized expertise, scheduling flexibility, and additional market knowledge. Reputable contractors maintain stringent vetting processes for all workers, including comprehensive background checks, license verification, insurance coverage requirements, and thorough evaluation of past performance and safety records.
12. Specialized Focus vs. Diversified Offerings
When evaluating a solar installer, consider whether they specialize exclusively in residential solar or offer a broader range of services, such as roofing, electrical contracting, or commercial solar solutions.
Companies with diverse offerings may leverage experience from other sectors to claim a longer business history, which may not necessarily reflect their specific expertise in residential solar. Inquire about the installer’s experience specifically with residential solar and ask if they have a dedicated point of contact (POC) for residential clients. A dedicated POC can ensure faster, more knowledgeable responses to your questions and concerns, helping streamline your homeowner experience.
Additionally, companies with multiple service streams can be more resilient in times of market volatility, potentially providing greater stability. However, specialized focus and dedicated support are often key to a successful solar installation experience for homeowners.
13. Manufacturer Certification
When selecting a perfect solar installer, it’s also essential to consider manufacturer certifications. Many reputable solar equipment manufacturers, like Enphase and Panasonic, offer certification programs and designate installer tiers such as Gold or Platinum levels. These certifications indicate that an installer has received specialized training and consistently meets the manufacturer’s quality standards.
If you’re considering a specific brand, contact the manufacturer to confirm that your installer holds the appropriate certifications. This extra step ensures you work with a fully qualified contractor to install the specific equipment you want, maximizing system performance and warranty coverage.
14. Workmanship Warranty Terms
A workmanship warranty protects you against installation errors and defects. Review the warranty terms carefully, including duration and coverage specifics. A contractor confident in their work will offer a solid warranty, providing you with peace of mind that any future issues will be addressed promptly.
Caution: Be wary of contractors offering 20-25 year warranties, especially if they are new in business. Unfortunately, many solar businesses have failed in the past year, rendering those warranties void. An insurance-backed warranty from Solar Insure will provide long-term protection.
15. Industry Associations
Membership in reputable industry associations, such as the Solar Energy Industries Association (SEIA) or the American Solar Energy Society (ASES), demonstrates a contractor’s commitment to industry best practices and ongoing education.
These affiliations often require adherence to codes of conduct and provide access to the latest industry developments.
16. Installation Timeline
Ask for a detailed installation timeline outlining each project phase—from initial site assessment to final grid connection.
A clear timeline helps set expectations and allows you to plan accordingly. It also reflects the contractor’s organizational skills and respect for your time.
17. Installation Volume Rates
Understanding how many installations the contractor completes each month can provide insights into their experience and operational capacity.
A higher installation volume may indicate efficiency and expertise, but ensure that quality isn’t compromised for quantity. Confirm they have adequate resources to give your project the attention it deserves.
18. OSHA Violations
Safety is paramount in solar installations. Check for any violations issued by the Occupational Safety and Health Administration (OSHA). A contractor with a clean OSHA record demonstrates a strong commitment to safety protocols, reducing the risk of accidents on your property.
19. Written Safety Program
A comprehensive, written safety program shows the contractor’s dedication to maintaining a safe work environment. Ask to see their safety policies and procedures.
A formal program indicates they take safety seriously, protecting both their workers and your property.
20. Financing Options
Understand the financing options the contractor offers. Some provide leases, power purchase agreements (PPAs), third-party ownership (TPO), or purchase options with financing plans. Choose a contractor that offers solutions aligning with your financial goals, whether that’s immediate ownership or a low upfront cost.
Note: Be cautious of companies heavily involved with TPOs and leases. Unfortunately, many TPOs have been late in paying contractors, which may pose financial issues for them.
