Photovoltaic tempered glass is a key material for solar modules. Its high light transmittance, high strength and weather resistance directly affect the power generation efficiency and lifespan of photovoltaic systems. The future trend is to be thinner, have higher light transmittance, and be more adaptable to the demands of double-glass and BIPV.
1. The application of photovoltaic tempered glass
A. Single-glass assembly
a. Structure: Tempered glass + EVA film + battery cells + back sheet (TPT/TPE).
b. Features: Low cost, widely used in ground-mounted power stations and rooftop photovoltaic systems.
B. Double-glass assembly
a. Structure: Tempered glass + solar cells + tempered glass.
b. Features: Stronger weather resistance, with a lifespan of up to 30 years, suitable for harsh environments such as offshore photovoltaic and agricultural photovoltaic.
C. BIPV (Building Integrated Photovoltaic)
It adopts semi-tempered or laminated glass, taking into account both light transmission and safety, and is used for glass curtain walls, photovoltaic roofs, etc.
2. Market trends of photovoltaic tempered glass
A. Thinning and lightness: 2.0mm glass is gradually replacing 3.2mm glass to reduce weight and cost.
B. Highlight transmittance: The popularization of AR coating technology enhances the efficiency of components.
C. Growth of double-glass modules: It is expected that the proportion will exceed 30% in the future.
D. Rising demand for BIPV: Building-integrated photovoltaics drives the demand for semi-tempered glass.
