What is a solar power EPC general contractor? What items will be included when implementing the EPC general contractor project? Let’s find out with VREnergy!

What is an EPC general contractor?

First is about the concept of EPC General Contractor , this is an abbreviation of three English words:

  • Engineering – Design
  • Procurement – ​​Procurement and supply of materials and technology equipment
  • Construction – Construction, implementation of construction

And VREnergy is one of the EPC General Contractors for solar power projects, we carry out all items from survey, design, supply of materials and equipment to construction and testing. and hand over to the investor.

What benefits will a solar power EPC general contractor have?

When choosing a capable and experienced solar power EPC general contractor, it will help you clearly outline an overall plan and be specific in each goal to be achieved of the solar power project :

  • Consulting and drafting plans before implementing the project, helping to optimize time and costs.
  • Ensuring product and equipment quality with high standards.
  • Minimize costs by using products, equipment and supplies at scale.
  • Our staff is experienced, accumulated through many completed projects.

VREnergy is proud to be the EPC general contractor for energy projects in general and rooftop solar power projects in particular with many years of experience in the renewable energy industry. VREnergy has extensive experience designing and constructing large-scale commercial and industrial projects.

To ensure quality and reputation in each project, VREnergy follows strict procedures for EPC general contractors. Implemented projects all meet design, construction, safety and equipment standards such as TCVN, ISO, FM Global. EMC, ISO/IEC, EN and other related standards.

EPC implementation process

The process of implementing a solar power project typically includes 4 main steps: survey, design, installation, operation and maintenance O&M .

Survey and consulting

Carry out factory roof survey, measure parameters, collect data to create implementation plan. We will provide cooperation agreement options with flexible policies (financial solutions, carbon credit consulting , green certificate consulting) and optimally according to the needs of your business.

Detailed design

Determine design options, installation scale, construction methods and select appropriate equipment. Simulate the system through 3D drawings and use PVsyst software to analyze expected output.

Construction and installation

Perform tasks according to the installation process such as constructing the transformer station, installing the support frame system, installing the substation, installing solar panels, installing inverters and electrical cabinets, pulling DC/DC wires. AC, connected to the grid, trial operation, acceptance and handover of the project to the investor.

Operation and maintenance

After installation, the EPC Contractor will provide operations and maintenance services for the business’s system through remote monitoring and periodic inspection of equipment at the construction site. Proper operation and maintenance will helps the system operate stably and long term.

  • Calculate and establish deployment scale
  • Survey the area where the solar power system will be installed

We will go to VREnergy’s showroom, supplier or completed project to learn about the technology and operating mechanism of the equipment products.

Select products, equipment and supplies

We must agree that the market has many quality products, equipment and supplies, but there are also risks in terms of quality.

Because products, equipment and supplies account for up to 70% of project implementation costs, this requires top attention.

Project implementation capacity

VREnergy has a professional team, including highly qualified engineers and workers, specializing in designing and installing solar power systems . That is confirmed through VREnergy’s presence in more than 120+ large and small solar power projects for households, businesses and investors throughout Vietnam.

Support for legal issues

We have the ability to advise & support in carrying out legal procedures when implementing solar power projects, helping businesses complete system documents, including environmental impact assessment reports. school, construction permit, fire protection permit, connection permit from EVN and the Department of Industry and Trade.

System warranty

Recognition of minimally effective recognition

Safety and quality are the top factors that businesses pay attention to when installing solar power. To ensure customers’ peace of mind, VREnergy introduces a third party to provide necessary types of system insurance during the implementation of solar power projects.

Fire insurance

Currently, many businesses are still afraid of installing rooftop solar power because of safety and quality issues. Solar power system insurance from reputable third-party insurance companies helps overcome all risks during installation and operation, helping customers feel secure when using it.

Electricity output insurance

Solar energy systems generate electricity mainly through the radiation of the Sun. Therefore, system power output may not be as expected due to customer environmental factors or system malfunctions. 

This is when insurance protects and pays for “Decreased system electricity output”. Insurance will open up opportunities for all investors who are interested and want to protect a stable source of revenue from their solar energy system.

Legal procedures

Currently, renewable energy projects such as rooftop solar power, biomass power, waste heat recovery… are receiving a lot of attention from domestic and foreign investors.

In short, a renewable energy system must have a license according to regulations to be implemented in practice. Investors must check and receive detailed instructions for specific cases to ensure that the project complies with the law.

To complete the project, VREnergy helps customers meet required license conditions as well as comply with state agency instructions.

Business registration certificate

Accordingly, the established enterprise must have a suitable business line for the implementation of solar power projects. In the case of foreign investors, they must be granted a Certificate of Investment and Development Registration. launch solar power project.

Fire prevention certificate

Fire Protection Certificate is a mandatory license to operate a rooftop solar power project according to law. The Fire Prevention and Fighting Police is the agency that issues Fire Prevention Certificates.

Construction permit

According to regulations, rooftop solar power is considered a construction project according to the current Construction Law. Therefore, a rooftop solar power project needs a construction permit to be allowed to install. Depending on the status of the construction work, the project owner must have a new construction permit or a corresponding repair and renovation permit.

Environmental impact assessment report

Pursuant to the provisions of Article 18 of the Law on Environmental Protection 2014, subjects that must carry out environmental impact assessment are:

  • The project falls under the authority of the National Assembly to decide investment policies; Government, Prime Minister;
