EPC Services in Solar Energy

Quanganhcons provides EPC contracting services for constructing rooftop solar power systems, ensuring the process from design to project completion professionally. Quanganhcons’ EPC solutions optimize costs, ensuring safety and high efficiency for solar EPC projects.

EPC (Engineering, Procurement, Construction) services in the field of solar energy is a comprehensive model providing end-to-end solutions for solar power systems. EPC solar services not only include design and technical consulting but also ensure quality from material supply to construction completion.

The EPC process is characterized by clear steps:

  1. Survey and project reception: The initial stage of the EPC contract is to measure detailed technical parameters and analyze the customer’s electricity needs to propose the most accurate design solution.
  2. Design and consulting: Using specialized technology to develop an optimal design, ensuring a balance between capacity, system efficiency, and costs.
  3. Supply and construction: During this process, equipment such as solar panel installation, inverter, and connection systems are installed according to international technical standards to maximize the efficiency and durability of the system.
  4. Operation and maintenance (O&M): Regular maintenance services and performance monitoring ensure the system always operates stably and efficiently.

Some notable points in the EPC contract:

  • Technology transfer and personnel training, helping customers self-operate the system.
  • Long-term warranty policy with commitment to rectify technical errors and ensure system performance.

Outstanding features of EPC services in solar energy include effective solar project management, from minimizing legal and technical risks to ensuring safety compliance with Vietnam Electricity (EVN) standards.

A notable trend is the integration of O&M services extending from 10-20 years, proving the effectiveness and reliability of renewable energy EPC services. Modern projects also utilize AI and IoT technology to monitor electricity and detect faults remotely.

However, businesses also face challenges such as fluctuations in material costs and changes in solar power pricing policies that may affect project profitability.

Trends in Renewable Energy Solutions

Quanganhcons applies advanced technology in renewable energy projects, from improving efficiency to optimizing energy. The company is committed to providing sustainable electricity solutions with a sustainable future approach, ensuring long-term competitiveness and efficiency for customers.

In recent years, the trend of renewable energy has become an essential part of the global energy industry, with strong motivations to achieve more sustainable and cleaner goals.

Growth of Renewable Energy

According to IEA forecasts, by 2025, renewable energy will account for more than one-third of global electricity. Although this is a significant step forward, this pace is still not sufficient to fully meet the targets set by the United Nations Climate Conference. Asia, particularly China, is emerging as a key region with half of the world’s electricity consumption, including one-third of global electricity consumed in China.

Technological Improvements

Energy technology is continuously being improved. A prime example is high-efficiency photovoltaic panels that are opening new opportunities in this field. Currently, solar energy projects are becoming increasingly efficient thanks to advancements in photovoltaic technology. Additionally, the return of nuclear energy through Small Modular Reactors (SMRs) is providing sustainable energy solutions for large data centers.

The Energy-Water Nexus

Another important trend is the integration of energy and water to ensure resources are used sustainably and most efficiently. This is a key factor in aiming towards sustainable electricity.

Global Energy Transition

On Earth Day 2025, the international community called for scaling up renewable energy threefold by 2030, the main motivation for this transition is to achieve clean energy use globally.

Electrification Infrastructure

The development of electrification infrastructure is helping to improve efficiency and sustainability in energy usage, creating a favorable environment for the development of green technologies. Brands like ABB, Schneider play a crucial role in this process.

This trend not only affirms the leading role of renewable energy technology but also opens up new opportunities and challenges for the industry, requiring the whole industry to join hands to achieve sustainable development goals.

Reference quick estimate
No quick estimate yet. You can still submit a project quotation request.

Quotation scope

Applies to one EVN-supplied substation with oil-immersed transformers at 22/0.4 kV (single-phase: 12.7/0.23 kV), with MV metering VTs/CTs supplied by EVN. The estimate includes the selected equipment, installation, earthing, transformer-to-main-breaker connections, design and connection documentation, and coordination of testing and utility acceptance.

Kiosk, integrated steel-pole and indoor substations include MV switchgear and the entered underground cable route. Other outdoor arrangements use the relevant protection configuration. The final diagram must meet the project connection requirements.

Excludes VAT, cables from the substation switchboard to the MSB/loads, live-line work, harmonic reactors, weak-ground treatment or special piling, land and special fire-protection provisions. Underground routes assume normal construction conditions and exclude road drilling and special reinstatement.

Prices are indicative investment budgets. A formal quotation follows site assessment and agreement on the configuration. Electrical selections are preliminary and require design verification before installation.

Capacity range and application conditions

The catalogue defines the enquiry range of this tool, not universal TCVN capacity limits. Single pole-mounted transformers: 15–100 kVA; three-unit banks: 3×15–3×100 kVA. Platform substations: 100–630 kVA. Steel-pole substations: 100–630 kVA; 750/800 kVA require design verification and local approval. Ground-mounted, kiosk and indoor configurations: 50–10,000 kVA. Not every configuration has a package price or the same structural design.

Reference: EVN Decision 1299/QD-EVN dated 3 November 2017, Volume 1, sections 3.3–3.4. Check the current requirements of the responsible utility before implementation. Kiosks must meet manufacturer ratings and testing requirements (IEC 62271-202); indoor and ground-mounted arrangements must meet project layout, ventilation, structural and fire-protection requirements. For multiple transformers, specify the quantity and capacity of each unit.
