The PV Module market: When real-world operation redefines selection standards

After more than a decade of development, solar power in Vietnam is entering a phase where the value of a system is no longer assessed at the point of installation, but proven throughout its operational lifecycle. For many enterprises, the core question is no longer “how many kWp to invest in”, but how well the system sustains performance, reliability, and operating costs over years of operation.

Following the period of rapid capacity expansion, Vietnam’s solar market is moving into a phase of consolidation and selection. Corporate customers, particularly FDI companies and export-oriented manufacturers, are increasingly placing greater emphasis on operational stability, data traceability, and compliance with ESG standards across global supply chains.

This shift is reshaping competition in the photovoltaic module market. Price is no longer the sole differentiator. Instead, the market is clearly diverging into two segments: one focused on “installing sufficient capacity”, and another that views solar systems as long-term energy assets requiring disciplined management over their entire lifecycle. 

It is real-world operational experience that has driven this change in perspective, as challenges related to performance degradation, maintenance costs, operational risks, and data management tend to emerge gradually over time, rather than at the initial investment stage.
Within a solar power system, PV modules are the core component determining energy yield throughout a 20–30 year lifecycle. However, their true impact only becomes evident once the system operates steadily over time. Minor differences in materials, manufacturing processes, or quality control may not be visible in the first year, but can result in significant performance and cost gaps after several operational cycles.

Therefore, beyond pricing considerations, operational reliability and the ability to maintain performance over time are becoming essential selection criteria, particularly for manufacturers, FDI enterprises, and companies participating in global supply chains.
In this context, IREX PV modules, manufactured and quality-assured by SolarBK, are positioned based on real operating conditions in Vietnam. Rather than focusing solely on nominal specifications, IREX is developed to meet project requirements for maintaining stable Performance Ratio (PR) and long-term system reliability.

Its differentiation does not lie in being a standalone product, but in how it is integrated into SolarBK’s closed-loop value chain, from system design and construction to operation and maintenance. This integrated approach minimizes fragmentation risks between stages, a common cause of performance decline in many systems after a short operational period.

Confidence in IREX quality is built upon real operating systems. At VinFast, rooftop solar systems using IREX modules have become part of the energy infrastructure supporting large-scale industrial production, meeting stringent requirements for stability, safety, and ESG compliance within global supply chains. IREX has also been deployed across various industrial, commercial, and service projects such as Alma Resort Cam Ranh, Leading Star, and Sợi Phú An, demonstrating adaptability to diverse operational and technical conditions.

Selection Standards for the Next Phase

As the solar market matures, price is no longer the sole criterion. It is evaluated alongside operational reliability, governance capability, and long-term performance. For many enterprises, solar power has become a strategic energy asset requiring professional lifecycle management rather than a short-term capital expenditure.

This is also how SolarBK and IREX approach the market: building trust based on proven operational results and long-term partnership capability.
