GCL SI Leads the Charge at Intersolar Europe 2025
In May 2025, Munich set the stage for one of the most pivotal events in the photovoltaic (PV) industry, the Intersolar Europe. GCL System Integration (GCL SI) made a notable impact by unveiling a series of groundbreaking technologies and comprehensive solutions that underline its leadership in solar innovations.
Revolutionizing Silicon Production
A highlight of GCL SI's exhibition was its revolutionary granular silicon product. Unlike traditional silicon lump production, which is energy-intensive, GCL's granular silicon employs advanced fluidized bed reactor technology. This innovative method achieves higher productivity, reduces carbon dioxide emissions by 42% (certified at 14,441 kg CO2e as of early 2025), and offers unprecedented cost efficiency. The spherical shape of the granular silicon not only enhances transportation and processing but also ensures a high purity level, making it an excellent raw material for downstream modules, a critical step toward grid parity.
High-Performance PV Modules
Making its European debut, the GPC2.0 module series impressed attendees with its ability to deliver 660W of power and a cell efficiency of 27.5%. With features like TOPCon 2.0 passivation, busbar-free design (OBB), and silver-free metallization, this series reduces overall costs by 28% while boasting an industry-leading temperature coefficient of -0.25%/°C. The modules are designed to be dust-resistant and good at handling shading, ensuring maximum output and aesthetic appeal for commercial rooftops and agricultural PV installations.
As a pioneer in the commercialization of perovskite PV modules, GCL SI also showcased two world records – a perovskite module with a certified stationary efficiency of 22.43% and a perovskite-silicon tandem module achieving an efficiency of 28.06%. Both records were certified by the National Institute of Metrology in China, signaling GCL SI's commitment to leading the next generation of solar solutions that aim for efficiencies exceeding 30%.
Tailored Solutions for Diverse Applications
GCL SI emphasizes customized solutions for various applications, ensuring energy supply installations are optimized for different terrains and climates. Their tailored systems for commercial PV installations aim to reduce energy costs and promote a green transition for businesses. Additionally, their residential PV solutions are designed to be sleek and user-friendly, broadening access to the benefits of solar energy for households. From photovoltaic-storage carports to offshore PV plants and climate-neutral campus solutions, GCL SI provides turnkey innovations.
Recognized Leadership and Global Partnerships
The company’s unwavering commitment to quality and innovation has not gone unnoticed. GCL SI received multiple awards recognizing its leadership within the industry:
- - BNEF 2024 Global PV Module Bankability Top 10, acknowledging product reliability.
- - Recognition as a BNEF Tier 1 supplier from 2021 to 2024 for outstanding production performance.
- - EcoVadis Silver Medal (2025) awarded for exemplary ESG performance.
A strategic partnership announcement with GALP further underscores GCL SI's role in shaping the future of solar energy.
Engaging Dialogue for a Sustainable Future
During the concurrent "The Next Era Forum," GCL SI, alongside representatives from SP, the Global Solar Council, Stäubli, and TÜV, engaged in discussions about industry trends. They introduced the SiRo Carbon Chain Platform, a comprehensive carbon management system encompassing raw materials, production, and application. This initiative exemplifies GCL SI's commitment to thrusting the solar industry into a carbon-neutral future.
The Intersolar Europe 2025 served as a platform for GCL SI to reinforce its ethos of being "Innovation-Driven, Quality-First, Customer-Centric." Through relentless technological advancements and cross-industry collaboration, GCL SI aims to pioneer a solar revolution marked by enhanced accessibility and sustainability for all.
