Since its establishment in 2007, Gain Solar has focused on Building Integrated Photovoltaics (BIPV), dedicated to upgrading photovoltaics from "external equipment" to building envelope materials and systems that can be directly adopted by architects, curtain wall consultants, and developers.
We are not only a photovoltaic material supplier but also a complete BIPV system provider, offering customers one-stop service from design to installation. We adhere to the engineering logic of "customizable, calculable, installable, and verifiable," providing systematic support to B2B customers from design collaboration to manufacturing and delivery.
Currently, we hold multiple BIPV-related patents and can provide customized BIPV components and system solutions tailored to building needs.
BIPV (Building Integrated Photovoltaics) integrates photovoltaic systems into building facades, roofs, or windows, allowing them to simultaneously serve both power generation and architectural functions.
• Power generation function: Transforming the building envelope into a distributed energy asset
• Architectural functions: Shading, lighting control, thermal insulation, airtightness and watertightness, weather resistance and safety, acoustic performance, etc.
• Design expression: Color, texture, light transmittance, arrangement patterns, etc., can be "controlled" by architectural language.
Unlike traditional photovoltaic modules, BIPV not only provides energy for buildings but also optimizes building physical performance, such as shading, thermal insulation, and lighting control. BIPV solutions bring sustainable energy and aesthetic value to buildings, improving energy efficiency while maintaining design flexibility.

Applicable scenarios: Glass curtain walls, skylights, facade windows, roofs, etc., making glass a customizable power generation medium.
Gain Solar's photovoltaic glass products combine power generation and aesthetics, offering customized sizes, colors, textures, and light transmittance to achieve both aesthetic and energy efficiency goals for building facades. Whether transparent or colored photovoltaic glass, it can be customized as needed to meet the needs of architects in terms of appearance design and energy efficiency. • Size/Shape: Customized according to modular dimensions and facade divisions.
• Color/Texture: Matches the architectural facade language and material system
• Light Transmittance and Visual Uniformity: Balancing natural lighting, glare control, and power generation
• Solar Cell Arrangement Pattern: Stripes/matrix, etc., considering both visual aesthetics and light transmission

Applicable Scenarios: Commercial complexes, headquarters offices, industrial parks, and public building facades, transforming the curtain wall from an "energy-consuming skin" into a "power-generating skin."
Our photovoltaic curtain wall system not only provides natural lighting and solar control but also achieves both power generation and aesthetic functions on the building facade through precise photovoltaic design. Each module can be customized according to the building's structure, color, and design requirements, ensuring consistency and a modern look for the building's exterior.
• Synergistic Natural Lighting and Solar Control: Reduces overheating risk and improves indoor comfort
• Diverse Appearance and Parametric Customization: Color, size, and light transmittance can be configured according to facade effects and functional requirements
• Controllable Project Delivery: A traceable and verifiable closed loop from development, design, production, installation to operation and maintenance

Applicable Scenarios: Building facade systems with high requirements for energy saving and comfort (public buildings, passive houses/low-energy buildings, park buildings, etc.), using "back ventilation" to enhance efficiency and enclosure performance.
• Back ventilation structure helps reduce component operating temperature and improve system efficiency factor
• Hollow/multi-pane structure provides stronger thermal and acoustic performance
• Controllable light transmission and visual effects: Achieving stripe, matrix, and other forms through solar cell arrangement, balancing lighting and aesthetics
• Extendable to higher standards: For example, a triple-pane system can meet more stringent energy-saving targets
Our ventilated photovoltaic facade adopts a double-layer hollow structure combined with a back ventilation design to improve the operating efficiency of the photovoltaic components. This system not only effectively generates electricity but also provides thermal and acoustic performance through its hollow design, making it an ideal choice for low-energy buildings and passive houses.

Applicable scenarios: Commercial atriums, transportation hubs, public building skylights, industrial and warehouse roofing. Photovoltaic skylights directly impact user experience: lighting environment, thermal environment, glare control, and visual comfort.
Photovoltaic skylight design optimizes natural lighting and solar filtering functions while providing a sustainable energy solution for buildings. The hollow structure improves thermal performance and controls light intensity, ensuring a comfortable indoor environment while providing green energy.
• Simultaneous power generation, solar filtering, and lighting environment optimization
• Improved overall thermal performance through hollow structure and material selection
• Offers a wide range of customization options to suit different building modules and design requirements

Applicable scenarios: Residential roofs, villas, cultural and tourism buildings. Looks like traditional roofing but provides stable power generation.
The design of solar roof tiles is inspired by traditional roof tiles, but they have power generation capabilities, perfectly blending architectural aesthetics and energy needs. We offer a variety of specifications, colors, and styles, making the roof not only beautiful but also providing stable energy support for the building.
• Installation efficiency and ease of maintenance
• Roof waterproofing and structural reliability
• Overall roof visual consistency
Beyond buildings, we also offer various PV+ product directions (such as photovoltaic carports, landscape/recreational facilities, paving tiles, guardrails, and sound barriers), extending the concept of photovoltaic materials to parks and urban spaces, helping clients achieve a visible green energy image and actual power generation benefits with lower "additional land occupation costs".
Through the customization of photovoltaic materials, we provide architects with unlimited design possibilities. Parameterized customization capabilities for size, shape, color, light transmittance, arrangement patterns, and size modules make BIPV a "free material" in architectural design, perfectly integrating into various architectural styles and needs. Energy Efficiency Improvement
• Building facade power generation, providing on-site energy
• Optimized daylighting and solar control to reduce air conditioning load
• Structural optimization such as double-skin facades and ventilated cavities to improve building envelope performance and thermal comfort
BIPV significantly improves building energy efficiency through the combination of power generation, shading, insulation, and ventilation functions. Through integrated design, the BIPV system can effectively reduce the building's air conditioning load, improve comfort, and reduce energy consumption.
Improving energy utilization efficiency with a more suitable electrical architecture (PEDF-BIPV approach)
We introduce the PEDF (Photovoltaic/Storage/DC/Flexibility) concept into our systematic solutions, emphasizing a more rational DC-side organization to reduce energy conversion losses and reserving interfaces for building energy storage, flexible loads, and future expansion. For customers who need to "scale up from demonstration to mass replication," this systematic thinking significantly improves long-term operational reliability.
We not only provide high-quality photovoltaic materials but also ensure the smooth implementation of projects through systematic solutions. From structural design to electrical systems, from installation support to operation and maintenance management, Gain Solar provides comprehensive technical and service support to ensure that BIPV projects are successfully implemented during the building construction process and achieve the expected energy efficiency goals.
• Structure and Load: Matching the structural design logic of curtain wall/roof/skylight systems
• Airtightness, watertightness, and drainage: Incorporating sealing and drainage paths into the system design
• Thermal expansion and contraction and weather resistance: Considering reliability under long-term cyclic environments
• Electrical safety and integration: Wiring organization, connectors, protection, and inspection paths
