Who is the top rated solar company?

There has been rapid growth in the solar energy industry in recent years, as more homeowners and businesses switch to solar to save money on electricity bills and help the environment. With so many solar installation companies to choose from, it can be challenging to identify the top players in the industry. This article provides an overview of the highest rated national solar companies based on customer satisfaction, quality of service, business longevity, and installer expertise. We will look at factors like pricing, warranties, solar panel quality and more to rank the cream of the crop in residential and commercial solar installation.

Ranking Methodology

There are several key metrics and data sources used to evaluate and rank solar companies in the United States. The leading rankings focus on factors like customer satisfaction, quality of products/services, company reputation, pricing and cost value, solar panel efficiency, and overall solar installation experience.

Data for the rankings come from consumer surveys, verified customer reviews on sites like SolarReviews and Yelp, third-party solar company review sites like EnergySage, internal company data on number of installations and customer complaints, and industry expert opinions.

Some of the most influential rankings come from organizations like CNET, Consumer Affairs, Forbes, and GreenMatch. These rankings tend to weigh customer satisfaction, product quality, and reputation highest in their evaluation methodology. Pricing, costs, and efficiency are secondary factors.

For example, the CNET 2024 ranking of best solar companies relied on over 5,000 customer surveys and reviews. It focused on customer service, product quality, pricing, and overall value delivered. Solar panel efficiency and wattages were only a small part of the evaluation. The ranking aims to identify solar providers that deliver an excellent overall experience.

Most of the major solar company rankings use a similar methodology focused on the customer experience. By aggregating data from surveys, reviews, and solar experts, they offer a data-driven perspective on the highest quality and most recommended solar installation companies.

Notable Runners-Up

While SunPower, Vivint Solar, Tesla Energy, SolarCity, and RGS Energy rounded out the top 5 highest rated solar companies, there were a few other notable companies that just missed making the cut:

Sunrun is one of the largest solar companies in the U.S., operating in 22 states. They are known for excellent customer service and innovative financing options like solar leases and power purchase agreements. However, Sunrun fell just short of the top 5 due to some complaints about pushy sales tactics from certain independent dealers. (source)

PetersenDean is a leading solar installer in California, well-regarded for roofing expertise and high-quality Panasonic solar panel installations. They did not crack the top 5 mainly due to limited geographic availability, but remain a great choice on the west coast. (source)

Baker Electric placed just outside the top solar companies primarily due to limited state availability in California. They are employee-owned and known for outstanding customer service alongside quality hardware and installations. For California residents, Baker Electric remains a top choice. (source)

The Future

The solar industry is poised for tremendous growth in the coming years. Analysts predict the global solar market will expand at a compound annual growth rate of over 20% from 2022-2027, with the United States and China leading installations [1]. Key factors driving this growth include declining panel costs, supportive government policies, and rising energy demands.

On the technology front, innovations in panel efficiency, energy storage, and solar manufacturing promise to further accelerate adoption. Perovskite solar cells and organic PV could enable ultra-efficient lightweight panels. Integrated solar storage systems will make solar more grid-friendly. Automation and improved materials will reduce manufacturing costs.

Industry consolidation is also expected as solar moves towards maturity. Larger vertically integrated players will likely acquire smaller companies to achieve economies of scale. However, an influx of oil and gas companies transitioning to solar could increase competition.

Overall, analysts are bullish on solar’s future as it becomes ever more cost-competitive with conventional energy sources. With supportive policies and continued innovation, solar is positioned to become a major pillar of the global energy mix this decade and beyond.


In summary, after reviewing the top solar companies based on ratings, customer satisfaction, and market performance, SunPower emerges as the top rated solar company overall. Key takeaways include:

  • SunPower panels have the highest efficiency ratings, producing 70% more energy than conventional panels.
  • With an A+ BBB rating and 4.8/5 stars on SolarReviews, SunPower leads in customer satisfaction.
  • As the second largest global supplier of residential solar systems, SunPower has a strong market presence and years of experience.
