Are you interested in going solar but feeling overwhelmed by the process? That’s where a Solar EPC company comes in. An EPC (Engineering, Procurement, and Construction) company specializes in managing the entire lifecycle of a solar project, from design and engineering to construction and maintenance. In this blog, we’ll mainly focus on learning what are solar EPC companies and what services do a solar EPC company provide.
What Services Do a Solar EPC Company Provide?
Apart from EPC and maintenance, complete project management and execution of solar projects, from conception to commissioning are among the services what are solar EPC companies providing. They ensure that solar projects are completed on time, within budget, and with high-quality standards.
1. Engineering
Solar EPC companies‘ engineering services, including site analysis, system sizing, and feasibility studies. They use advanced software to conduct a detailed analysis of the site’s solar potential, including the available solar radiation and shading analysis.
They also perform a technical and economic feasibility study to assess the project’s viability and potential return on investment (ROI). Based on these studies, the solar EPC company designs a solar energy system that meets the client’s requirements and maximizes energy generation.
2. Procurement
They procure high-quality solar modules, inverters, batteries, and mounting structures from reputable manufacturers. It is a crucial aspect of any solar project, and solar EPC companies have an extensive network of suppliers and vendors for solar components. Solar EPC companies ensure that the procurement process is transparent and cost-effective and that the components used are of high quality.
3. Construction
It includes civil works, installation, and commissioning of solar projects. They have experienced project managers, engineers, and skilled labor to ensure that the construction process is efficient and safe. Solar EPC companies ensure that the solar system is installed as per the design, and all the necessary safety protocols are followed.
4. Operations and Maintenance
It includes preventive and corrective maintenance services to keep the system running smoothly and optimally. To track the system’s performance and identify issues, if any, they provide performance monitoring services. By providing reliable and efficient O&M services, solar EPC companies ensure that the system operates at peak performance, maximizing energy generation and ROI.
5. Financing
Some solar EPC companies also provide financing options to their clients. They have partnerships with financial institutions that offer customized financing solutions to clients. These financing options help clients to fund their solar projects without incurring significant upfront costs. Now you should have understood what services do a solar EPC company provide.
Quality Control And Assurance Measures Offered by Solar EPC Companies

Below are the measures provided:
1. Design Review: Before starting any installation work, solar EPC companies review the solar power system’s design to ensure that it meets the required standards of quality and performance. This includes checking the system’s design, layout, and orientation to ensure optimal performance.
2. Component Testing: They test all components of the solar power system before installation to ensure that they meet the required quality and performance standards. This includes testing solar panels, inverters, and other components for efficiency, durability, and reliability.
3. Installation Quality Checks: During installation, solar EPC companies carry out quality checks to ensure that the system is installed to meet the required quality standards. This includes checking the system’s wiring, connections, and grounding to ensure that they are installed correctly.

What is EPC Cost in Solar?
Typically, EPC costs range from $1.38 to $1.97 per watt (Wp). At the same time, solar panels and inverters are a lot more expensive than any other components as they make up about 40-50% of all expenses incurred respectively.
EPC cost in solar varies depending on a variety of factors like the location of the installation site, the complexity as well as the size of the system, and the specific services provided by the EPC company. It may also vary depending on the EPC contractor you select.
In conclusion, investing in solar energy is a wise choice, but navigating the complexity of designing, constructing, and maintaining a solar installation can be difficult. A solar EPC business can help with that. By understanding what services do a solar EPC company provides you can make an informed decision when selecting a company to help you go solar.
