Amidst increasingly volatile electricity prices, the demand for CO₂ emission reductions, and the strong energy transition trend in Vietnam, solar power is no longer just about “installing panels,” but has entered a phase of optimizing operation, storage, and energy self-sufficiency.
Therefore, the Solar + BESS (Battery Energy Storage System) model is becoming a strategic choice for industrial and commercial (C&I) businesses. To effectively implement this model, the roles of solar contractors, EPC general contractors, and M&E contractors are becoming increasingly important.
Therefore, Unify Energy cordially invites reputable solar contractors nationwide to collaborate on Solar + BESS projects, aiming for financial efficiency, technical safety, and sustainable development.

What is the Solar + BESS solution?
Solar + BESS is an integrated solar power (Solar PV) system with battery storage, allowing for the storage of excess electricity generated during the day and flexible use according to the actual needs of the business.
Specifically, the Solar + BESS system allows:
– Store excess electricity when solar power is high and load is low.
– Provide electricity during peak hours, periods of high electricity prices, or when the grid is unstable.
– Ensure backup power in case of power outages or production interruptions.

Why should businesses and solar contractors implement Solar + BESS now?
A direct solution to the problem of ever-increasing electricity costs.
For C&I businesses, electricity costs are becoming one of the largest operating expenses. Solar + BESS allows for:
– Reduced reliance on the grid
– Limiting electricity purchases during peak hours
– Optimizing electricity pricing based on actual load
This helps shorten the payback period and improve investment efficiency for investors – a factor that businesses are increasingly focusing on when implementing energy projects.
Overcoming the limitations of traditional solar power systems
Solar systems without storage often encounter problems such as:
– Not fully utilizing solar power during the day
– Limited power generation or grid overload
– Inability to guarantee power supply during grid outages

Opportunities to increase project value for solar contractors.
For solar contractors, implementing Solar + BESS offers clear benefits:
– Increased contract value and project revenue
– Expanded solution scope from “installation” to “total energy consulting”
– Gain a competitive advantage when bidding on large-scale C&I projects.
– Better meet the growing needs of corporate clients.
Solar contractors who master BESS solutions early will have a distinctly different position compared to those who only deploy traditional solar power.
Unify Energy is pursuing strategic partnerships within the Solar + BESS ecosystem
Unify Energy aims to build a strategic partnership network with solar contractors, EPC general contractors, and engineering firms operating in the renewable energy and industrial infrastructure sectors in Vietnam. Our goal is to connect parties with practical implementation capabilities to form a Solar + BESS solution ecosystem that effectively meets the technical, operational, and investment efficiency requirements for the industrial and commercial (C&I) segments.
Instead of focusing on short-term, project-by-project collaborations, Unify Energy prioritizes a long-term partnership model where parties collaborate from needs assessment and solution consulting to engineering design, system implementation, and operation. This approach standardizes implementation processes, reduces technical risks, and improves project quality, while also creating a foundation for partners to expand their capabilities and achieve sustainable growth in the Solar + BESS market in Vietnam.

The practical return on investment when investing in a Solar + BESS system
When businesses invest in a solar system combined with BESS (Building, Energy, and Service) technology, the return on investment needs to be viewed more holistically compared to traditional solar power. Instead of just calculating the electricity saved during the day, Solar + BESS generates multiple sources of financial value simultaneously, optimizing investment efficiency in practice
First, solar power generated during the day is stored in the BESS system and used at appropriate times, especially during peak hours when electricity prices are high. This allows for more efficient utilization of each kWh of solar power. For example, with a 1 MWp solar system combined with a 1–2 MWh BESS, average savings can reach VND 120–150 million per month, equivalent to VND 1.4–1.8 billion per year from self-consumption and load shifting.
In addition, BESS helps businesses cut peak power consumption from the grid, thereby reducing peak power costs – a significant expense for many factories and industrial parks. In many cases, these savings can account for 10–20% of the total monthly electricity bill, significantly shortening the system’s payback period.
Beyond direct savings, Solar + BESS also provides value in terms of operational stability and proactive power supply. The system helps mitigate the risk of power outages, reduce the likelihood of production disruptions, and protect critical equipment. While difficult to quantify in specific costs, this is a factor that significantly impacts the long-term financial performance of businesses.
With a total investment of approximately 18–22 billion VND for the Solar + BESS configuration described above, the actual payback period typically ranges from 5–7 years. After the payback period, the system continues to generate stable savings for many years to come, making the combination of BESS with Solar not just a technological choice, but a sound and sustainable investment decision.
Conclusion
In the context of increasing demand for cost-effective energy solutions and stable operation, the Solar-Based Building System (BESS) model is opening up opportunities for substantial and sustainable collaboration between solar contractors, EPC general contractors, and engineering firms. Choosing the right partner not only ensures efficient project implementation but also directly impacts long-term financial viability and competitiveness in the market.
