210mm Bifacial PV Modules Market
Introduction
The market for 210 mm bifacial photovoltaic (PV) modules has emerged as a crucial frontier in the solar energy industry. With the larger wafer size enabling higher power outputs, and bifacial modules capturing reflected sunlight from both the front and rear surfaces, this format offers enhanced energy yield and improved economics. The rise of 210 mm bifacial modules is being driven by escalating demand from utility‐scale solar power plants, technological advancements (especially in N‑type cell architectures), and aggressive deployment in regions such as Asia‑Pacific. As module formats evolve and economies of scale grow, companies are investing heavily in manufacturing capacity for 210 mm bifacial modules.
From a strategic standpoint, the adoption of the 210 mm format (and associated technologies such as TOPCon, HJT) represents a shift in the PV value chain, one that promises lower levelised cost of electricity (LCOE) and better performance under real‑world conditions.
Market Overview
The global 210 mm bifacial PV modules market is projected to grow at a strong pace over the coming years. Estimates indicate a compound annual growth rate (CAGR) ranging from about 9 % to 10.5 % for the period 2025–2033, depending on the source. One forecast pegged market size at approximately USD 12.8 billion in 2024, expanding to USD 28.4 billion by 2033. Another report placed a base size near USD 5.2 billion in 2024 and projected USD 12.7 billion by 2033. Clearly, the large‐format (210 mm) and bifacial combination is gaining momentum.
The shift to the 210 mm wafer size has been rapid: for example, industry data suggests that about 80 % of Chinese PV producers had 210 mm capability as of mid‑2022, with 210 mm modules taking a growing share of shipments. The advantages of the format include higher power ratings, improved energy yields (including under low‑irradiance conditions), and lower balance‑of‐system costs per watt.
Nevertheless, the market also faces challenges: supply chain bottlenecks, raw material inflation (for silicon, wafers, encapsulation materials), and policies/regulations affecting module trade and incentives. Moreover, deployment in smaller applications (like residential rooftops) may lag compared to utility‑scale, due to cost sensitivity and logistics of larger modules.
Overall, the trajectory is strongly positive for 210 mm bifacial modules, especially in large scale power plants and commercial/industrial applications.
Key Drivers
Several factors are fueling the uptake of 210 mm bifacial modules:
Higher energy yield: The bifacial module captures light from both front and rear surfaces; when combined with the large 210 mm wafer size, energy yield gains are noticeable. For example, outdoor testing showed that a 210 mm wafer format module achieved up to 1.6 % higher yield compared to a 182 mm format in certain conditions.
Cost reduction: The larger wafer size allows more power per module and fewer modules required for the same output, thereby reducing installation labour, wiring and mounting costs. Further, bifacial modules extract more energy per unit area, improving the economics of projects.
Manufacturing scale and capacity expansion: Many manufacturers have invested substantially in large‑format production lines. The 210 mm format is becoming mainstream, thereby driving economies of scale.
Policy/regulatory support: Incentives and renewable‑energy targets in many regions are pushing solar deployment. Utility‐scale developers favour high‑power modules (often 600 W+), for which 210 mm bifacial formats are suited.
Technological synergy: 210 mm modules are often paired with advanced cell technologies such as N‑type or TOPCon, further improving efficiency, lifespan and performance under low light or high temperature.
