Your Reliable Partner For Custom Special Glass In China

Solar Glass

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

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.

Custom Solar Glass

Custom Solar Glass For PV And BIPV Projects

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.

Solar Glass Processing Capabilities

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.

Selection System

Use the operating requirement first, then confirm the glass family, processing route and inspection method.

Prioritize transmission, surface texture, tempering, edge condition and long-term outdoor durability.

Engineering Data System

Light

Define visible transmission, solar transmission and haze separately.

Strength

Tempering and edge quality support handling and outdoor use.

Assembly

Lamination film, cell layout and sealing affect the glass specification.

Durability

Coating, surface and packaging must suit outdoor exposure.

Selection FAQ

What information should I send for a quotation?

Send the drawing, glass type if known, dimensions, thickness, tolerance, quantity, application and any edge, hole, printing, coating or strengthening requirement.

Can Specialglass help select the material?

Yes. Provide the operating temperature, optical requirement, chemical exposure, mechanical load and installation method. The engineering team can narrow the suitable glass families before quoting.

Are custom shapes available?

Custom discs, plates, windows, holes, slots, steps and CNC profiles can be reviewed against the selected material and process route.

Saving your time and cost is our common pursuit.

Tell us the material, size, thickness, tolerance, quantity, application, and any holes, slots, edges, coating, printing, or polishing requirements. We can manufacture custom glass components from your drawing, CAD file, sketch, or sample.
