TaiyangNews, one of the most influential global PV media platforms, successfully hosted the Advanced Solar Module Applications 2025 conference. Christian Comes, Director of Business Development at Huasun Energy, delivered a keynote titled “Vertical PV and Batteries - Maximizing the Market Value of PV in the Next Decade.” Through a comprehensive comparison of mainstream PV plant topologies, Christian demonstrated how vertical PV has become the key to unlocking full lifecycle value in solar power plants and offers a practical path to overcoming today’s profitability challenges.
From Power Output to Power Value
As markets such as Europe and California enter the stage of high PV penetration, the growing mismatch between peak solar generation at noon and flat electricity demand has driven midday power prices sharply downward, making traditional south-facing fixed tilt systems less advantageous. Unlike conventional installations, Huasun’s vertical east–west HJT modules produce a distinctive dual-peak generation curve that aligns perfectly with morning and evening demand peaks. By avoiding the midday price valley, vertical PV systems significantly enhance the overall value of generated electricity.
Vertical Installation: Precision Generation for Stronger Returns
In his presentation, Christian evaluated the economic performance of four common PV topologies - South Fixed Tilt, Trackers, Dome East/West, and Vertical E/W systems — using battery storage as a key comparative variable. The comprehensive simulation results covering CAPEX, OPEX, generation yield, and income clearly demonstrate the superior overall performance of vertical installations. In a modeled German market, vertical systems achieved 3% higher energy yield, 20% higher Energy Sales Income, and 13% Energy Sales Net Income compared with traditional south-facing fixed tilt systems, while achieving profitability levels comparable to much more expensive tracking systems.
With a simple fixed structure and no moving parts, vertical installations avoid the mechanical failure risks and higher maintenance costs associated with trackers, offering a more robust and reliable long-term solution for investors.
HJT Technology: The Core Engine Behind Vertical Value
The performance of vertical PV systems is powered by Huasun’s Kunlun Series HJT modules, built on advanced 0BB cell technology and verified by international certification authorities for nearly 100% bifaciality. This exceptional bifacial performance takes module efficiency to a new level, substantially increasing energy generation potential. Their dual-peak generation profile aligns perfectly with high-price hours in the morning and evening, allowing the system to capture greater energy revenue during premium electricity periods. Meanwhile, optimized land utilization, lower BOS, and reduced O&M costs further enhance overall project economics, driving both cost efficiency and energy yield.
Vertical + Storage: Expanding the Value Horizon
Battery systems are not better investments for spot market income in 2025, yet they still hold strategic potential when combined with vertical PV. Vertical installations naturally act as a "price protection" mechanism, shifting generation hours to avoid low-price periods. When paired with storage, they can capture additional nighttime revenue opportunities through arbitrage, grid services, and capacity bonuses, expanding value streams as electricity markets continue to evolve and midday prices erode further.
From continuous breakthroughs in HJT technology to the precise application of vertical modules, Huasun is driving the PV industry toward a new era of optimized design, refined operation, and maximized profitability. Vertical PV is more than a new installation approach—it is a forward-looking pathway powering the sustainable future of global clean energy.
