Gain Solar integrates clean energy generation into modern architecture through advanced BIPV façade systems. By combining aesthetics, safety, and performance, our façade solutions transform building envelopes into active, power-generating assets—delivering long-term energy benefits and sustainable value without compromising architectural design.
Whether for commercial landmarks, public buildings, or green-certified developments, Gain Solar’s façade systems offer fire-rated safety, superior weatherproofing, and seamless integration with building structures and aesthetics.
BIPV façades redefine how buildings interact with light, heat, and the environment. They merge renewable energy with architectural creativity, enabling façades that are functional, efficient, and visually distinctive.
Architectural integration: Replace conventional cladding with solar-active glass or panels that blend into the building design.
Energy generation: Convert façades into sustainable power sources, reducing operating costs and carbon emissions.
Green certification: Contribute to LEED, BREEAM, or national green building credits with documented EPDs and energy data.
Fire and weather performance: Achieve A1/A2 fire ratings, with high wind resistance, watertightness, and acoustic insulation.

1. How does a BIPV façade differ from a conventional solar panel?
BIPV modules are structural building materials, replacing glass or cladding elements. They serve both as the building envelope and a power generator, offering integrated design and weatherproofing without external racks.
2. Do colored or semi-transparent modules affect power generation?
Yes. Colored or patterned glass slightly reduces power output, but Gain Solar optimizes cell spacing and coating to balance aesthetics and efficiency for each project.
3. How is A1/A2 fire performance achieved?
Through the use of non-combustible glass laminates, mineral interlayers, and fire barriers within the substructure. Each assembly is verified through full-scale fire tests.
4. Can BIPV façades be maintained or replaced easily?
Yes. Gain Solar’s systems allow modular replacement without dismantling adjacent panels, ensuring maintenance-friendly façades.
5. What is the typical warranty period?
Gain Solar provides 25 years of power output warranty and 10–15 years of product and installation warranty, depending on project specifications.
Gain Solar’s BIPV façade solutions redefine architectural envelopes—turning passive surfaces into active, sustainable, and aesthetic energy systems.
With certified fire safety, proven durability, and full-lifecycle engineering support, we help architects and developers achieve net-zero buildings that inspire and perform.
