SolarWorld to Test Mono-PERC Bifacial Modules at University

published: 2016-03-08 18:43

Bifacial PV module is a method to better power generation, while mono-PERC cell is already one of the mainstream high efficient PV technologies. SolarWorld combines them together and creates a mono-PERC bifacial PV module lineup. To test the reliability of such modules, SolarWolrd’s U.S. manufacturing hub has produced its first ficacial Bisun modules for installation as part of a 205kW PV array at the University of Richmond in Virginia.

The solar system site will simultaneously compare performance of standard modules using p-type mono-PERC cells and Bisun module using the same cells. According to SolarWorld’s estimation, the mono-PERC bifacial Bisun modules can generate up to 25% more energy compared with standard mono-facial modules of the same nominal wattages because the modules absorb solar radiation on both the front and back sides.

For more accurate performance data comparisons, both types of modules will be installed on top of both a gravel roof and a roof of vinyl-like white material TPO (thermoplastic olefin). Actual power generation from bifacial modules depends on both the distance they are installed from a surface beneath them as well as the composition and therefore reflectivity of that surface.

“Thanks to the university, we will provide a system that produces clean power while also demonstrating the in-field capabilities of technological innovation,” said Mukesh Dulani, U.S. president of SolarWorld. “Aside from making the university greener, this installation will provide a strong set of performance data in a real-world application.”

Secure Futures is responsible to develop the project, while SolarWorld will co-own the solar system. Secure Futures has also secured a PPA with Dominion Power Virginia and the University of Richmond will purchase power generated by the array.
