High-efficiency Solar Glass Materials

Targray supplies solar PV glass materials engineered to enhance the conversion efficiency and power output of solar photovoltaic panels. Our product portfolio features tempered, ultra-clear solar glass solutions with anti-reflective coating that diminishes reflectivity and improves light transmission. It is supported by a suite of solar procurement solutions and services designed to help businesses of all sizes lower their material procurement costs, unlock value and accelerate growth.

Patterned Solar PV Glass

Ultra-clear, patterned solar PV glass solutions engineered to help maximize light transmission while minimizing absorption and reflectivity – characteristics which contribute to improving overall conversion efficiency in solar cells.

 

  • Glass density: ≈2.5g/cc
  • Solar transmittance (3.2mm): ≥91%
  • Glass iron content: ≤120ppm
  • Poisson’s ratio: ≈0.2
  • Young’s modulus of elasticity: ≈73GPa
  • Tensile strength: ≈42MPa
  • Hemispherical emissivity: ≈0.84
  • Expansion coefficient: 9.03×10m/k
  • Softening point: ≈720℃
  • Annealing point: ≈550℃
  • Strain point: ≈500℃

Tempered Solar Glass with Anti-reflective Coating

The solar glass materials we provide can be coated with a cutting-edge anti-reflective film prior to glass tempering. The anti-reflective coating – developed using an advanced nanoporous silica technology – further reduces reflectivity and improves light transmission to raise the conversion efficiency and power output of PV modules.

 

  • Approximately 2.54% greater transmittance than uncoated equivalent
  • Diffuses reflectiveness of glass surface, lowering light polution to environment
  • High-temperature tempering ensures film is firmly binded to PV glass
  • Resistance to acid and alkali environment provides additional layer of protection for the cell

Working closely with our supply partners and organizations including U.S-based SEIA, Targray helps solar manufacturers and project developers worldwide enhance the sustainability of their supply chains. Contact us today to learn more.
