Risen Energy Showcases Next-Generation PV and BESS Solutions

730 Wp+ HJT modules and a 5 MWh energy storage system signal Risen’s push toward ultra-efficient, low-carbon utility-scale solutions

Risen Energy strengthened its global technology leadership at PVBook 2025, unveiling two of its most advanced products to date: the eTron 5.016 MWh battery energy storage system (BESS) and high-efficiency HJT photovoltaic modules delivering over 730 Wp. Together, these solutions highlight Risen’s focus on performance, long-term reliability, and one of the lowest carbon footprints in the photovoltaic and storage industry.

The launches reflect a broader shift in global energy markets, where renewable generation, grid congestion, and zero-price events are accelerating demand for integrated, high-performance solar-plus-storage systems.

eTron 5.016 MWh: Utility-Scale Storage Designed for High-Density Deployment

Risen’s eTron energy storage system delivers a nominal capacity of 5,015.96 kWh with a rated power output of 2,500 kW, positioning it firmly in the utility-scale and large commercial segment.

A key technical differentiator is its liquid cooling system with intelligent three-stage temperature control, which limits temperature deviation between battery modules to less than 2 °C. This tight thermal balance enhances safety, extends battery life, and improves long-term system efficiency—critical factors for bankable BESS projects.

From a deployment perspective, the eTron system uses a compact back-to-back and shoulder-to-shoulder layout, reducing land use by more than 46% compared with conventional containerized solutions. This makes it particularly attractive for space-constrained projects, co-located solar-plus-storage sites, and grid-edge installations.

Safety and compliance remain central to the design. The system meets or exceeds leading international standards, including UL9540A, GB/T 36276, and NFPA 855, and integrates:

• Active fire suppression

• Fast overcurrent disconnection

• Combustible gas detection

These features address increasingly strict regulatory and insurance requirements across Europe, the Americas, and other mature storage markets.

As Andrés Pinilla, Risen’s Director of Storage for Europe and Latin America, previously noted, “Storage is no longer optional; it’s a must-have,” particularly as zero-price hours and grid congestion become structural features of renewable-heavy power systems.

730 Wp+ HJT Modules: High Efficiency Meets Long-Term Durability

Alongside storage, Risen presented its latest heterojunction (HJT) solar modules, delivering:

• Up to 730 Wp of output

• More than 23.5% module efficiency

• Only 0.3% annual degradation, ensuring 90.3% power retention after 30 years

These performance metrics place the modules among the most durable and efficient options available for utility-scale and high-performance commercial projects.

The modules incorporate several advanced technologies, including:

• Hyperlink interconnection, improving current flow and reducing resistive losses

• Ultra-thin wafers, lowering material consumption

• UV conversion technology, increasing light utilization while mitigating radiation-related degradation

Beyond electrical performance, Risen has emphasized lifecycle sustainability. Its HJT manufacturing process significantly reduces silver usage and limits water consumption to around 200 t/MWp, contributing to an industry-leading carbon footprint of just 376.5 kg CO₂eq/kWc—a critical metric for ESG-driven investors and low-carbon procurement frameworks.

An Integrated Solar and Storage Strategy

Risen’s presence at PVBook 2025 underlined a strategic message: the company is not positioning itself as a component supplier alone, but as an integrated energy solutions provider.

According to Pinilla, Risen’s storage offering extends beyond hardware to include:

• System engineering and design

• Medium-voltage integration

• Energy management systems (EMS)

• Financing support

• Long-term operational services

This end-to-end approach is designed to help project owners optimize revenues, manage risk, and maximize asset profitability across diverse market conditions.

Looking ahead, Risen is already developing next-generation HJT and tandem modules targeting up to 850 Wp, while accelerating the rollout of large-scale storage projects across Europe and Latin America, where it has established strategic partnerships and active installations.

Positioning for the Next Phase of the Energy Transition

As renewable penetration increases and power markets become more volatile, the combination of high-efficiency PV and advanced energy storage is rapidly becoming the standard rather than the exception.

With its 730 Wp+ HJT modules, 5 MWh-class storage systems, and a strong focus on carbon reduction and system integration, Risen Energy is positioning itself at the intersection of performance, bankability, and sustainability—three pillars that will define the next phase of global solar and storage deployment.
