The rise of solar power and the role of solar companies

Solar energy is shining brighter than ever in the USA, with more people recognizing its potential to fight climate change and government incentives boosting its popularity. According to a SEIA report, in 2022, the U.S. added 20.2 GWdc of PV capacity, resulting in the country's total installed capacity reaching 142.3 GWdc, enough to run 25 million homes. Interestingly, solar energy represented 50% of all new electricity-generating capacity added in 2022, which is the largest annual share in the industry's history. Moreover, residential PV installations achieved a record high of nearly 6 GWdc, showing a 40% surge from the previous year.

Solar energy has become more accessible thanks to the growing number of US solar companies providing diverse products and services to cater to customers' needs. As of 2023, there are 435 companies in solar energy sector operating in the country, up 18.8% from the previous year, according to industry research firm IBISWorld.

Top criteria to consider when evaluating solar panel companies

Evaluating solar providers can be daunting, especially if you are new to the industry. However, there are some key criteria that you can use to assess potential solar companies to work with. In this section, we will look at the top factors to consider.


When it comes to assessing solar energy companies, their reputation holds significant weight. It reflects their past performance, indicating their trustworthiness and reliability in delivering exceptional products and services. You can begin to evaluate the reputation of solar companies by browsing through their online reviews and ratings, which will give you an insight into their customer satisfaction levels. Additionally, you can request references from several solar companies and chat with their previous customers to gain a deeper understanding of their experiences.


The experience of solar panel companies is another important aspect to consider when evaluating them. Since solar energy is a relatively new field, numerous solar companies have only been operating for a short time. Therefore, it's vital to choose a provider with a high level of expertise and a successful track record in the industry. Experienced solar companies are more likely to have the required knowledge and skills to design and install an ideal PV energy system. Moreover, established solar energy companies often have established supplier connections, ensuring that their solar panel systems are constructed with the highest quality materials.

Quality of the panels

Quality of the PV panels should be a top priority when comparing solar energy companies since it can have a large impact on how well the entire system performs. They are a significant investment that can last for many years, so it's essential to choose a reputable firm that offers durable, high-quality panels. Opting for quality equipment not only ensures that it generates more energy but also that it requires less maintenance throughout its lifespan. To assess the quality, key factors to consider include the materials used, panel efficiency, and component durability.

The materials utilized in solar panels play a critical role in determining their overall quality. Typically, premium panels offered by the best incorporate monocrystalline silicon cells that have greater efficiency in converting sunlight into electricity. Moreover, quality products usually come with solid warranties that ensure their performance and power output for a specific period.

Pricing and financing options

When it comes to assessing solar panel companies, it's crucial to take financing options into account as well. PV system costs can vary significantly, which means it's essential to do a comparative analysis of prices and opportunities across various providers. Some solar companies offer financing options, such as leases or loans, which can make the initial cost of a system more feasible. Moreover, a few providers might also present incentives or rebates, which can drive down the overall expenditure of a solar panel system even further.


An important aspect to take into account is the warranties and guarantees solar companies offer. Trustworthy solar energy companies should provide comprehensive warranties on their products and services, offering you peace of mind that your investment is safeguarded in case of any defects or malfunctions. Additionally, it's vital to ensure that solar companies provide guarantees on their installation work to ensure optimal system performance for the long term. You should also consider solar companies that offer performance guarantees, ensuring that your photovoltaic energy system will generate a specified amount of energy over a given period of time.

Customer service and support

Finally, it's essential to evaluate the customer service and support of multiple solar panel companies. Look for solar companies that are quick to respond, pay attention to detail, and have effective communication skills. It's ideal to go for an installer with a dedicated customer support team to swiftly address any queries or issues. Additionally, it's wise to consider solar energy system companies that provide ongoing support and maintenance services to ensure your setup runs at peak performance.
