There’s no denying solar energy is booming these days, and companies are popping up everywhere. Chances are you’ve encountered some form of a solar company; whether you’ve been actively researching solar energy benefits, had someone knock on your door to talk about solar, or spent time on social media only to be inundated with solar advertisements. However, the term “solar company” can be vague as not all solar companies offer the same services. Understanding the differences can help you make an informed decision when investing in solar energy. We’re here to help. 

Evaluating Solar Energy Companies

Solar Equipment Manufacturers 

In the aviation industry, companies like Boeing and Airbus manufacture planes. They don’t sell directly to passengers—airlines handle that. The solar panel industry manufactures the system components, while sales and installation are managed by separate providers. There are numerous solar equipment companies worldwide, ranging from specialized manufacturers like Tesla and Enphase, which focus solely on solar technology, to larger household electronics giants such as Hyundai and Panasonic, which include solar divisions within their broader product offerings. 

Solar Sales Organizations 

These companies are strictly sales organizations that typically have door knockers or consultants that are visiting you at your home and seeing if solar makes sense for you. These organizations work directly with solar installers and contractors who assist in completing the installation. In most cases, these sales organizations are third-party contractors, meaning the installer does not employ them directly. 

Solar Installers 

If solar panel manufacturers are like aircraft builders, solar installers, like an EPC described below, are like the airlines you interact with when booking a flight. When you install a solar system, your solar installer will likely be the company you engage with the most throughout the process. Solar Installers ensure completing the project on time, and provide warranties, such as workmanship or roof penetration warranties. These would be separate from any Manufacturer Warranties. Manufacturer warranties cover specific components like panels, batteries and inverters.

Here’s a great resource from our blog on How to Choose a Solar Company, with insights into other types of solar companies. 

Solar financing companies 

Solar financing companies may participate in your project if you choose to finance your solar system through their services. There are various solar financing companies, each with their own offering to help make the switch to solar affordable and easy.  

What is an EPC Solar Company? 

An Engineering, Procurement, and Construction (EPC) solar company, sometimes called a vertically integrated solar company, provides end-to-end services. These services include consultative sales, system design, equipment procurement, project management, installation, and support for maintenance or warranty claims. With an EPC solar company, like Solar Topps, you work with a single entity throughout your project, ensuring quality and accountability. EPC solar companies typically handle everything in-house. This helps minimize the risks associated with subcontracting, including unforeseen delays and unexpected price increases.

Advantages of EPC Solar Companies 

1. Seamless Project Management: EPCs handle all aspects of the project, from initial assessments to final commissioning. This holistic approach reduces the burden on clients by eliminating the need to coordinate multiple parties, ensuring a smoother and more integrated project execution. 

2. Quality Assurance: With expert engineers and technicians, EPC companies ensure that solar systems are built to high-quality standards. This reduces the risk of malfunctions and enhances the system’s performance over its lifetime. 

3. Cost Efficiency: EPC companies often have established relationships with suppliers, enabling them to procure equipment at competitive prices. Their expertise in efficient system design helps maximize the return on investment by minimizing energy costs. 

4. Project Timelines: Experienced EPC companies are adept at managing projects. Solar systems are installed and operational as scheduled, thereby avoiding delays and additional costs.  

5. Credentials – Industry-standard certifications are awarded through organizations like the North American Board of Certified Energy Practitioners (NABCEP)—widely recognized as the gold standard among renewable energy system installers.
