Solar panel tempered glass

Overview

Ultra white 3.2mm &4mm solar panel glass , are specially designed for encapsulation material of solar modules. The design reduces the direction reflectance and increase the internal reflection that the solar energy can be absorbed effectively. It ensures the maximum transmittance of the soar and raise the efficiency of electricity generation. The glass observes the properties of high solar transmittance, low absorbance, low reflectance, superior physical strength and significant flatness, is the ideal encapsulation material for solar thermal and photovoltaic modules.

Professional manufacture of AR ( Anti Reflective) solar glass which is mainly used solar  collector,monocrystalline / polycrystalline photovoltaic / solar module and other energy products , display  cabinets etc. our products are involved in solar glass, Photovoltaic/PV glass, anti-reflection solar glass,  anti-reflection photovoltaic/PV glass anti-reflective solar glass

Functions:
1. High transmittance: 94-98%
For the same solar (PV) module, it can improve the power of more than 3% in the coated glass.
2. Self-cleaning function:
As the photovoltaic module is placed in the outdoor, easy to get dust, resulting in the decline in the power  of the solar (PV) modules. Coated glass has the self-cleaning function which can ensure the normal operation  of the solar(PV) module
3. Extend using circle:
Coated glass can effectively extend the service life (typically 25 years). Ensure the normal power generation  of solar(PV) modules.
