How to Choose the Right Solar Installation Company: Factors to Consider



With the growing demand for clean and renewable energy, many homeowners are considering solar power as an alternative to traditional electricity sources. However, choosing the right solar installation company can be a daunting task. There are numerous factors to consider, from the company’s credentials and expertise to the quality of their workmanship and reputation. In this comprehensive guide, we will explore the key factors you should consider when selecting a solar installation company, ensuring that you make an informed decision that meets your specific needs.

1. Credentials and Certifications

When choosing a solar installation company, it is crucial to consider their credentials and certifications. Look for companies that are licensed, bonded, and insured to install residential solar projects in your area. The North American Board of Certified Energy Practitioners (NABCEP) certification is widely recognized as the gold standard among renewable energy system installers. A company with NABCEP-certified installers demonstrates their commitment to professionalism and expertise in the field.

Furthermore, inquire about the company’s experience in installing solar equipment and their knowledge of the entire process. It is advisable to work with installers who have at least three years of experience and can provide references from previous clients. Ask them about the modules they use and why, their understanding of solar incentives and warranties, and how they handle any post-installation issues.

2. Transparency and Communication

Transparency is key when it comes to solar installation. A reputable company should be upfront and willing to answer all your questions about the installation process. They should provide clear explanations and keep you informed at every step. If subcontractors are involved, inquire about their credentials and the level of oversight provided by the primary installer.

Additionally, the company should assess your roof’s condition before installation. Ask if they recommend any repairs or adjustments and who will be responsible for any damage or leaks that may occur during the installation process. Clear communication and transparency ensure that you have a complete understanding of the work being done on your property.

3. Reputation and Testimonials

Before making a decision, it’s important to research the reputation of the solar installation company. Read online reviews and testimonials from their previous customers to get an idea of their service quality and customer satisfaction. The company should be able to provide references from past clients who can share their installation experience.

Talking to friends, neighbors, and colleagues who have gone solar can also provide valuable insights. Their direct feedback and personal experiences can help you gain confidence in choosing the right solar installation company.

4. Pricing and Quotes

When comparing solar installation companies, it is important to obtain multiple quotes to ensure you are getting a competitive price. Most experienced installers will assess your home and provide a price proposal based on factors such as your home’s size, energy usage, and other considerations. Ask for a breakdown of the costs and ensure that you understand how the company arrived at the quoted price.

It is essential to note that the cheapest quote may not always be the best option. Consider the quality of products, warranties, and the company’s reputation alongside the price. The Lawrence Berkeley National Laboratory’s Tracking the Sun report provides installation prices across the United States, which can serve as a helpful benchmark for comparison.

5. Local Expertise and Knowledge

Choosing a solar installation company with local expertise can have significant advantages. Local companies are familiar with the specific building codes and regulations in your area, making the installation process smoother. They also have a better understanding of the local climate and conditions, allowing them to tailor the solar system design to meet your specific needs.

Additionally, local installers often have established relationships with local inspectors and utility companies, minimizing potential delays or complications. They can navigate through any changes in utility requirements and ensure your system meets all necessary standards.

6. Warranty and Maintenance

A reliable solar installation company should offer comprehensive warranties to protect your investment. Inquire about the warranties they provide, including performance warranties and equipment warranties. Performance warranties typically guarantee a certain level of power generation over a specified period, while equipment warranties cover any defects or malfunctions in the solar system components.

It is important to understand the terms and conditions of the warranties, including coverage, duration, and any exclusions. Additionally, ask about the company’s maintenance services and their responsiveness in case of any issues or necessary repairs.

7. Financing Options

Considering the cost of solar installation, it is essential to explore the financing options offered by the company. Some companies provide their financing packages, while others may partner with financial institutions to offer loans or leasing options. Evaluate the different financing options available and choose the one that best suits your financial situation and long-term goals.

Solar-specific loans, home equity loans, green energy loans, power purchase agreements (PPA), or leases are common financing options to consider. Each option has its advantages and disadvantages, so it’s important to carefully assess the terms, interest rates, and ownership implications before making a decision.

8. Turnaround Time and Home Visit

When selecting a solar installation company, inquire about their turnaround time and availability. Understand the company’s schedule and when they can commence work on your project. The installation duration may vary depending on the type and size of the system, but the company should provide you with a clear timeline.

Additionally, a home visit is crucial for accurate assessments and design proposals. Ensure that the company is willing to visit your premises to evaluate your specific requirements and roof structure. This visit allows them to provide a tailored solar system design that maximizes efficiency and meets your energy needs.

9. Expertise and Track Record

The expertise and track record of a solar installation company are vital considerations. Look for companies with experienced installers who have a deep understanding of solar energy systems. The North American Board of Certified Energy Practitioners (NABCEP) certification is a valuable indicator of expertise and professionalism.

Review the company’s portfolio and inquire about their previous installations. A reputable company should be able to showcase their work and provide examples of systems they have installed. Consider their track record and the longevity of their business to ensure they will be available for ongoing support and maintenance.

10. Additional Services and Support

Beyond the installation, consider the additional services and support offered by the solar installation company. A full-service provider can offer a comprehensive solution, including equipment sales, financing options, and ongoing maintenance. Working with a company that takes care of every aspect of your solar project ensures a seamless experience and peace of mind.

Furthermore, inquire about the company’s customer support and responsiveness. A reliable company should be available to address any questions or concerns throughout the installation and beyond. Their commitment to customer satisfaction and ongoing support is an important factor to consider.


Choosing the right solar installation company requires careful consideration of various factors, from credentials and reputation to pricing, warranties, and local expertise. By following the guidelines outlined in this comprehensive guide, you can make an informed decision that aligns with your goals and ensures a successful solar installation. Remember to research, compare quotes, and ask detailed questions to find a reputable company that meets your specific needs. Going solar is a significant investment, and choosing the right solar installation company is crucial for a seamless and satisfying experience.
