Photovoltaic glass transmittance reading range

01(EN) vol1 20160508

For PV modules, the transmittance of glass directly affect the final solar energy on cells, thereby affect the generating power. So the higher transmittance is, the higher power generation will be. In order to improve the transmittance of glass, reducing the glass reflectance and absorptance. By reducing the Fe2O2 content ( ≤ 0.015%),

How to use Transmittance meter to measure Photovoltaic Glass

The light transmittance of photovoltaic glass refers to the proportion of light passing through the glass in the visible spectrum range. If the light transmittance of photovoltaic glass is higher, it can absorb more sunlight and convert it into electricity. Therefore, light transmittance is one of the important parameters to evaluate the
