Importance of Measuring Transmittance and Reflectance

In the realm of photovoltaic technology, the efficiency of solar panels is significantly influenced by the optical properties of the glass used. Transmittance and reflectance are two critical parameters that determine how much sunlight is absorbed and converted into electricity. The BS EN 62805-2:2017 standard provides a systematic approach to measuring these parameters, ensuring that PV glass meets the necessary quality standards for maximum energy conversion.

Transmittance

Transmittance refers to the amount of light that passes through the PV glass. High transmittance is desirable as it allows more sunlight to reach the solar cells, thereby increasing the overall efficiency of the solar panel. The BS EN 62805-2:2017 standard offers precise methods to measure transmittance, helping manufacturers and engineers optimize the design and material selection for PV glass.

Reflectance

Reflectance, on the other hand, is the measure of light that is reflected off the surface of the PV glass. Minimizing reflectance is crucial as it ensures that more light is absorbed rather than lost. The standard provides detailed procedures to accurately assess reflectance, enabling the development of PV glass with superior optical properties.
