Key takeaways


o, you've decided to power your home with solar energy — an excellent move! With a sea of solar companies in the US, each claiming they can make your green goals a reality, the challenge is finding the one that's just right for you. It's not just about which company has the flashiest ads or the most charismatic salespeople. There's more to it, from quality to cost, and we're here to guide you through the maze.

Must-Consider Factors in Making Your Pick

Quality of Workmanship

When looking for an installer, your top priority should be the quality of their work. Keep in mind that this is a long-term investment, so your solar energy installation should be durable and reliable. Quality workmanship not only ensures the solar panels function optimally but also minimizes maintenance issues down the line.

In House vs. Subcontracted Work

It's worth considering whether the solar energy installer manages the entire process in-house or outsources the work to subcontractors. Outsourcing isn't necessarily a deal-breaker, but it could add complexities to the equation. If a solar company uses their own team, they're more likely to be familiar with the products, which can be beneficial in the long haul.

Reputation in the Business

Don't underestimate the role of a strong reputation. Both word-of-mouth recommendations and online reviews can give you valuable insight into the reliability of the solar company. Go beyond the star ratings and delve deeper into customer comments to see if the solar installer consistently excels in meeting or surpassing client expectations.

A solar energy consultant advises clients on solar system design, installation, and maintenance, helping them make informed decisions about renewable energy adoption.

Energy Equipment Options

In the realm of energy systems, you'll find that not all panels and inverters stand on equal footing. The array of options can be staggering, but it's crucial to choose a company that offers a range of high-quality products. This will allow you to tailor the energy system to your specific requirement, whether you're looking to maximize energy output or work within a budget.

Warranty Terms

Solar warranty is another factor that shouldn't be overlooked. A long warranty period signifies the installer's confidence in their workmanship and the products they sell. Always read the fine print to understand what is covered and for how long.

Cost-Benefit Analysis

Lastly, conducting a cost-benefit analysis is key. While it's tempting to opt for the solar energy installer offering the lowest price, this may end up being more expensive in the long term if it involves cutting corners on quality. Weigh the initial investment against long-term perks like energy savings, quality, and warranty coverage.
Some solar energy companies in California include SunPower, Sunrun, and Tesla Energy. These firms offer various solar solutions for homes and businesses.

The Best Solar Energy Companies in the US

The abundance of solar energy companies in USA means that those interested in utilizing the sun’s power have an array of choices. While it's great to have options, it can also make the decision tougher. Don't worry; we're about to delve into some of the standout solar energy firms to help you make a smart choice.


SunPower, which was launched back in 1985 in San Jose, California, has built an impressive reputation as one of the go-to solar companies in the US for top-notch solar panel efficiency. The installer covers all 50 states, making it easily accessible no matter where you live. SunPower's Maxeon line, manufactured by its sister entity, Maxeon Solar Technologies, is the champ in efficiency, reaching 22.8%. You can also take advantage of SunPower’s comprehensive EnergyLink monitoring system and mobile app to keep tabs on your system. And when it comes to warranties, SunPower offers an all-inclusive 25-year guarantee, covering both equipment and installation.

ADT Solar

Originally founded as SunPro Solar in 2008 and acquired by ADT in 2021, ADT is another behemoth in the American solar installation scene. With a vast network covering 48 states, it's likely you can take advantage of their services. One of the standout features of ADT is the generous 25-year warranty on components like inverters. Whether you're interested in purchasing, financing, or leasing your solar energy setup, ADT offers all these options. They also extend extra services like roof repair through third-party affiliates, and they promise to match any competitor's price.


Momentum Solar brings customization to the forefront of solar energy installation. They don't tie you down to a single manufacturer; instead, they offer solar equipment from a selection of several different brands. But there's a catch: they currently operate in only 11 states. This limitation is strategic, as Momentum has focused on states with robust net metering programs. They'll even assist you in enrolling in solar incentive programs and sort out the permitting paperwork for you.


Established 15 years ago, Sunrun has grown to be a trendsetter in residential solar energy installations. They operate in 22 states, primarily through leasing solar panels to homeowners. For those who would rather purchase, that option is also available. Sunrun goes the extra mile for their leasing customers by offering comprehensive maintenance and monitoring services. If you opt to purchase, you'll rely on the standard 25- to 30-year manufacturer warranties. Sunrun's commitment to quality is backed by a 10-year workmanship warranty which provides protection against problems in the solar installation process and potential roof damage.
