This photovoltaic skylight roof system is an innovative BIPV (Building Integrated Photovoltaics) product that integrates building functions and power generation performance, meticulously developed by our company. This product deeply integrates photovoltaic power generation technology with traditional skylight structures, and the transparent solar panel also functions as the glass, transforming building roofs from simple skylights and rain shelters into green energy carriers with clean electricity production capabilities.
Product Description
This building integrated photovoltaic (BIPV) skylight is a comprehensive structural product integrating power generation, wind and snow protection, waterproofing, and light transmission. Its design fully considers the diverse market demands for BIPV products, possessing strong environmental adaptability and applicability to most building scenarios.
Regarding optical performance, the solution supports customized light transmittance, ranging from 10% to 80%. Depending on the lighting conditions of the installation site and indoor lighting requirements, users can flexibly choose different transmittance options to meet both the building's natural lighting requirements and ensure the power generation efficiency of the photovoltaic modules. In terms of weather resistance, the glass features a layer of solar cell that converts solar irradiation into electricity, while also providing thermal insulation, resulting in a stable effect on greenhouse plant photosynthesis and effectively improving indoor environmental quality.
Advantage
▶ Integration of building and power generation
The solution uses photovoltaic modules directly as the enclosure structure of the building's daylight roof, replacing traditional skylight materials, so that the top of the building can simultaneously meet the conventional functions of lighting, ventilation, waterproofing, etc., while simultaneously achieving clean power production, achieving "dual use of one thing", and significantly reducing the overall cost of the building.
▶ Flexible light transmittance customization
The light transmittance can be flexibly adjusted within the range of 10% to 80%, which can meet various indoor lighting needs from bright commercial atriums to soft residential spaces. Users can choose the most suitable light transmission solution based on the building's use function, local lighting conditions and indoor lighting requirements.
▶ Excellent weather resistance and heat insulation properties
This design is particularly beneficial for application scenarios that have special requirements for light and temperature, such as greenhouses, and helps improve the crop growth environment and indoor comfort.
▶ Beautiful appearance and strong adaptability
The product appearance design is elegant and beautiful, and the color matching and texture processing can be customized according to the architectural style to meet the needs of modern architecture for the dual integration of aesthetics and functionality. The product can be perfectly integrated with various building forms such as skylights, steel frames or traditional wooden structures, and is suitable for various application scenarios such as greenhouses, villas, exhibition halls, bus stops and commercial buildings.

Applicable Scenarios
▶ Greenhouse Agriculture and Ecological Farms
The product's high light transmittance customization capability (10%~80%) allows for precise matching of light transmission solutions to the different light requirements of various crops, while also providing heat insulation, offering an ideal green energy solution for modern agriculture.
▶ Residential and Villa Rooftops
Converting traditional pitched or flat roofs into photovoltaic skylights can provide clean electricity to residences without compromising the original architectural style, while improving the lighting and insulation performance of the rooftop space, enhancing living comfort.
▶ Commercial Building Atriums and Office Floors
Commercial building skylights typically have large areas and high lighting requirements. The SF-PVRO0F series can achieve efficient power generation while allowing large areas of light, effectively reducing building operating energy consumption and enhancing the building's green image.
▶ Outdoor Pavilions, Bus Stops, and Public Facilities
For public buildings such as bus stops, park pavilions, and exhibition halls, photovoltaic (PV) skylights not only meet the functional needs of providing shade and rain protection but also provide power for lighting, advertising light boxes, and other facilities, enabling self-powered operation of green public facilities.
▶ Cultural Venues and Landmark Buildings
The application of PV skylights in landmark buildings such as cultural venues and conference centers not only provides clean power generation but also allows for customized color and texture designs, becoming an artistic expression element of the architecture.
Important Notes:
▶ Structural Verification Before Installation
As a crucial component of the building envelope, photovoltaic (PV) skylights require a structural engineer to verify the load-bearing capacity of the original building structure before installation. PV modules must not be damaged during storage, handling, or hoisting. During hoisting, the bottom should be padded with wood, and the back should not be subjected to any impact or heavy pressure.
▶ Tilt Angle Design
The installation tilt angle should be no less than 3° to ensure unobstructed drainage and reduce the impact of water and dust accumulation on power generation efficiency.
▶ Regular Maintenance and Cleaning
Since photovoltaic (PV) skylights are exposed to the outdoor environment for extended periods, regular surface cleaning is recommended to maintain optimal power generation efficiency. Simultaneously, check the integrity of waterproof structures such as sealing strips and drainage channels to ensure long-term stable system operation.
▶ Electrical Safety
Electrical safety regulations must be strictly adhered to during installation and maintenance to ensure the integrity and reliability of the grounding system.
