Your Reliable Partner For Custom Special Glass In China
We manufacture and supply solar glass for photovoltaic modules, BIPV façades, solar roof systems, greenhouses, and solar thermal collectors. From low-iron tempered cover glass to patterned, prismatic, TCO-coated, printed, and laminated solar glass, we help customers match the right glass structure to light transmission, strength, safety, and project requirements.
Solar glass is the functional glass used in solar energy systems. It protects photovoltaic cells, supports long-term outdoor exposure, and allows sunlight to pass through with minimal loss. For different solar applications, the glass may need high transmittance, low iron content, surface texture, anti-reflective coating, conductive coating, printing, lamination, tempering, or special shapes.
For standard PV modules, low-iron tempered glass is often selected for its clarity and strength. For BIPV façades, roofs, skylights, and canopies, the glass also has to meet architectural requirements such as safety, appearance, transparency, color, and installation structure. For thin-film solar cells, TCO conductive glass becomes part of the electrical and optical structure of the module.
Solar panel glass is used as the front cover of crystalline silicon PV modules. It protects the solar cells from impact, moisture, wind, dust, and outdoor exposure while allowing sunlight to pass through with minimal optical loss. Standard framed modules commonly use tempered patterned low-iron glass, while double-glass and lightweight modules may use thinner glass on both the front and back sides.
Low iron solar glass contains less iron than ordinary clear float glass, which reduces the green edge color and improves light transmission. It is the base material for most photovoltaic cover glass, solar thermal collector glass, and high-transmittance energy glazing. Low iron glass can be supplied clear, patterned, tempered, coated, printed, or laminated depending on the final application.
AR coated solar glass uses an anti-reflective coating to reduce front-surface reflection and improve solar transmittance. It is commonly used in high-efficiency PV modules, bifacial modules, solar farms, and projects where higher energy yield is required. The coating can be selected according to the target transmission, durability, cleaning conditions, and outdoor environment.
Tempered solar glass is heat-treated to improve mechanical strength and safety. It offers better resistance to wind load, snow load, hail impact, thermal stress, and handling damage. After tempering, glass cannot be cut or drilled, so all holes, notches, cut-outs, and edge processing must be completed before toughening.
Glass-glass solar modules use glass on both the front and rear sides instead of a polymer backsheet. This structure improves moisture resistance, mechanical stability, weather durability, and service life. It is also commonly used for bifacial solar modules, where the rear glass allows reflected light to enter the back side of the cells.
This glass comes pre-coated with a transparent conductive oxide. The coating works as a see-through electrode layer, which is what thin film and heated-glazing applications need.
Patterned solar glass is rolled with a textured surface to reduce reflection and improve light trapping. The surface pattern helps direct more sunlight into the module instead of reflecting it away. It is widely used for crystalline silicon solar modules, solar collectors, and applications where higher solar transmission and outdoor durability are required.
Not sure which solar glass is suitable for your project? Send us your drawing, module structure, glass size, thickness, and application. We will help you choose the right material, processing method, and glass build-up.
We supply custom solar glass for module manufacturers, solar system integrators, architectural glass projects, and energy-building applications. The glass can be processed according to your drawing, module size, façade design, installation method, and performance requirement.
For PV modules, we can provide low-iron patterned glass, tempered solar glass, AR-coated glass, thin glass for glass-glass modules, and coated glass for higher solar transmission. For architectural solar projects, we can supply laminated BIPV glass with custom cell spacing, transparency, color, printed pattern, and safety glass structure.
Solar glass is processed before tempering, including cutting, edge grinding, drilling, notching, cut-outs, and ceramic frit printing. After tempering, the glass can be coated, laminated, inspected, packed, and supplied for module assembly or building installation.

We process solar glass from raw low-iron sheets to finished panels ready for module assembly or architectural installation. Our services include CNC cutting, edge grinding, drilling, tempering, ceramic frit printing, coating, lamination, inspection, and export packing.
Glass is cut to the required size before tempering. Holes, notches, cut-outs, mounting slots, and edge finishes are also completed before toughening, because tempered glass cannot be cut or drilled after heat treatment. For solar module applications, edge quality and dimensional accuracy are controlled to support stable lamination and assembly.
Depending on the project, we can supply AR-coated glass for higher transmission, anti-soiling coated glass for outdoor environments, TCO-coated glass for thin film or conductive applications, and ceramic frit printed glass for borders, busbar masking, shading patterns, or architectural design.
For BIPV and glass-glass solar modules, we support laminated structures using EVA, POE, PVB, or SGP. Laminated solar glass improves safety, moisture resistance, impact performance, and long-term outdoor durability, especially for façades, skylights, canopies, roofs, and overhead glazing.
