Choosing a solar panel company is one of the most important decisions you’ll make when transitioning to renewable energy. A solar installation is a big financial investment, costing tens of thousands of dollars, and the quality of that installation will affect your home’s energy production and value for decades to come. Yet many homeowners rush into contracts with the first company that knocks on their door or offers the lowest price, only to discover later that cutting corners on installation quality leads to expensive problems down the road.
The solar industry has grown quickly in recent years, and while this expansion has brought more options to consumers, it has also introduced challenges. Not all solar companies operate with the same level of expertise or commitment to quality. Some rely on commission-driven sales teams that prioritize quick deals over customer education. Others subcontract installations to unlicensed workers or use outdated equipment. These shortcuts can result in underperforming systems, safety hazards, voided warranties, or costly repairs that negate the financial benefits of going solar.
This guide will walk you through everything you need to know to hire the best solar panel company for your home or business. You’ll learn which certifications and licenses matter most, how to evaluate a company’s experience and reputation, what insurance coverage protects you, and how to identify red flags before signing a contract. Whether you’re a homeowner in North Carolina looking to reduce your utility bills or a business owner seeking to invest in clean energy, understanding these criteria will help you make an informed decision and make sure your solar project delivers maximum value for years to come.
Why Choosing the Right Solar Contractor Matters
Protect Your Investment
A residential solar installation costs between $15,000 and $30,000, depending on system size and equipment quality. For commercial projects, that investment can reach six figures or more. While these upfront costs may seem large, solar panels pay for themselves over time through reduced electricity bills and increased property value. The average homeowner sees a return on investment within 7 to 12 years, after which the system generates free electricity for another 15 to 20 years.
These financial benefits only materialize when your system is designed and installed correctly. Poor installation practices can reduce energy production by 20% or more, extending your payback period and cutting into your long-term savings. Improperly installed panels may develop leaks that damage your roof, create electrical hazards that require expensive repairs, or fail to meet local building codes, forcing you to pay for corrections out of pocket. Some homeowners have discovered that their systems were installed with inferior components or improper wiring, leading to premature equipment failure and voided manufacturer warranties.
Choosing an experienced, reputable solar contractor protects your investment by ensuring your system is designed for performance and built to last. A quality installation maximizes energy production, minimizes maintenance needs, and preserves the manufacturer warranties that protect you from unexpected expenses.
Ensure Safety and Compliance
Solar panel installation involves complex electrical work that must comply with national and local building codes. These regulations exist to protect homeowners from electrical fires, electrocution, and structural damage. Licensed solar contractors understand these requirements and follow proper procedures for roof mounting, electrical connections, and system grounding. They know how to safely integrate solar panels with your existing electrical system and make sure all work meets inspection standards.
Unlicensed or inexperienced installers may skip safety steps to save time or cut costs. Common mistakes include inadequate grounding that increases fire risk, improper roof penetrations that cause water damage, and electrical connections that create shock hazards. These errors put your family, your property, and the workers themselves in danger. In some cases, improperly installed systems have caused house fires or roof collapses that resulted in total losses.
Working with a licensed, insured solar contractor gives you peace of mind that your installation meets all safety standards and building codes. If something does go wrong, their insurance coverage protects you from liability and ensures repairs are made correctly at no additional cost to you.
Criteria for Hiring a Solar Panel Company
Licensing and Certifications
Professional certifications and licenses demonstrate that a solar company has the technical knowledge and experience to design and install high-quality systems. The most important credential to look for is NABCEP (North American Board of Certified Energy Practitioners) certification. This nationally recognized certification requires rigorous training, hands-on experience, and passing an exam covering solar design, installation, and maintenance. NABCEP-certified professionals stay current with the latest industry standards and best practices through ongoing education requirements.
In North Carolina, solar contractors should also hold a state electrical contractor license, as solar installations involve substantial electrical work. Companies that employ Professional Engineers (PE) with expertise in electrical or structural engineering provide an additional layer of quality assurance. These licensed engineers can design systems that maximize energy production while ensuring structural integrity and code compliance.
Be cautious of companies that rely solely on unlicensed sales representatives or subcontract installation work to uncertified crews. These arrangements can result in inconsistent quality and leave you with limited recourse if problems arise. When evaluating solar companies, ask to see proof of certifications and licenses, and verify that the professionals who will design and install your system hold the appropriate credentials.
Experience and Track Record
Experience matters in solar installation. Companies that have been in business for many years have encountered and solved a wide range of installation challenges. They understand local permitting requirements, know which equipment performs best in your climate, and have established relationships with utility companies and building inspectors that streamline the installation process.
Ask contractors how long they’ve been installing solar systems and how many projects they’ve completed in your area. Companies with hundreds or thousands of successful installations are more likely to deliver quality results than newer firms with limited track records. Request references from recent customers and take the time to contact them. Ask about their overall experience, whether the system performs as promised, and how the company handled any issues that arose.
Also inquire about the company’s approach to installation. Do they employ their own crews, or do they subcontract the work? In-house installation teams typically deliver more consistent quality because they work directly for the company and receive ongoing training and supervision. Subcontracted crews may not have the same level of expertise or accountability, which can lead to installation errors and service problems.
Reputation and Customer Reviews
A company’s reputation provides valuable insight into their reliability, customer service, and quality of work. Start by researching online reviews on platforms like Google, Better Business Bureau, and solar-specific review sites. Look for patterns in customer feedback. Do reviewers praise the company’s professionalism, communication, and installation quality? Or do complaints about poor workmanship, missed deadlines, or unresponsive service appear frequently?
Pay attention to how companies respond to negative reviews. Reputable contractors address concerns professionally and work to resolve issues, while less reliable companies may ignore complaints or respond defensively. Also consider asking for references directly from the company. Speaking with past customers gives you an opportunity to ask specific questions about their experience and see completed installations firsthand.
Red flags to watch for include high-pressure sales tactics, promises that sound too good to be true, and companies that push you to sign contracts immediately without giving you time to review the details. Legitimate solar companies will provide detailed proposals, answer all your questions, and give you space to make an informed decision. Avoid contractors who rely on commission-only sales representatives, as these individuals may prioritize closing deals over matching you with the right system for your needs.
Insurance Coverage
Proper insurance coverage protects you and the installation crew during your solar project. At a minimum, solar contractors should carry general liability insurance and workers’ compensation coverage. General liability insurance covers property damage or injuries that occur during installation, such as damage to your roof or landscaping. Workers’ compensation protects you from liability if an installer is injured while working on your property.
Before hiring a contractor, request proof of current insurance and verify coverage amounts. Some homeowners have faced financial disaster when uninsured installers damaged their property or workers were injured on site, leaving the homeowner liable for medical bills and repairs. Reputable companies will readily provide certificates of insurance and welcome your due diligence.
Home and Electrical Layout Expertise
Every home is unique, with different roof orientations, shading patterns, electrical panel configurations, and energy needs. The best solar companies employ in-house engineers and designers who can evaluate your specific situation and create a customized system that maximizes performance. These professionals should assess your property in person, measure roof angles, identify shading issues, and review your electrical panel to make sure it can accommodate the solar system.
Be wary of companies that offer cookie-cutter solutions without conducting a thorough site evaluation. A one-size-fits-all approach often results in undersized or poorly configured systems that fail to deliver the energy savings you expect. Look for contractors whose sales and engineering teams work together to ensure proposed designs are technically sound and aligned with your goals.
Quotes and Pricing Transparency
Obtaining multiple quotes from different solar companies helps you understand market pricing and compare the value each contractor offers. The lowest bid isn’t always the best choice. Some companies cut prices by using inferior equipment, employing unlicensed installers, or excluding important services like ongoing maintenance and warranty support.
When reviewing quotes, make sure each proposal includes information about equipment brands and models, warranty coverage, estimated energy production, and the full scope of work. Ask what’s included in the price. Does the quote cover permitting, inspections, utility interconnection, and system monitoring? Will the company help you apply for available incentives and rebates? Understanding what you’re paying for allows you to make fair comparisons and avoid hidden costs down the road.
