PV modules has created a standard material-level test to assess the expected optical performance of encapsulation at its interface with the PV cell. The protocol, colloquially known as the “transmittance standard,” describes the measurement of optical transmittance and subsequent analysis of pλ, YI, and cUV λ E.

JIS R3106 stipulates methods for measuring and calculating visible transmittance, visible reflectance, solar transmittance, solar reflectance, and normal emittance as indices for expressing the properties of flat glass.

•Optical transmittance (τ) is a key performance characteristic for encapsulation. •Encapsulation discoloration continues to be correlated to performance degradation in recently fielded PV modules.

The test setup requires data logging and selection for irradiance (pyronameter), ambient temperature (temperature sensors), cell temperature (thermocouples attached on the back side of the module corresponding to the two central cells), wind speed (speed sensor) and wind direction (direction sensor).
