pv magazine test: October 2019 results

Share

The first chart above gives the meteo station data (irradiance and ambient temperature) for October 2019. The monthly energy yield data for the months from May to October 2019 are provided in the table below. The second chart above shows the total energy yield of all products for October 2019.

Control test

A control test was set up among three Znshine modules back in August 2019. One of the two graphene-coated modules (ZXP6-60-275/P) is cleaned weekly, while the other one is not cleaned at all. A module with regular glass (ZXP6-60-265/P), which is not cleaned, has been installed as a reference. The average energy yield of the three is charted to the right. Comparing the coated module (B) and the module (C) that has never been cleaned, we observed a 1.6% energy yield boost (increased 0.5% compared with September’s result) from the graphene-coated module between September and October 2019.

Overall bifacial boost for October 2019 averages 7.1%. We investigated bifacial boost for products above green colored plastic and the newly installed grey gravel background.
