SolarWorld's bifacial modules getting their first real-world run out in the US


SolarWorld’s highly anticipated mono-PERC bifacial modules are finally being installed in a commercial system in the United States. The company has high hopes for its bifacial Bisun technology, and this system presents them with the perfect opportunity to prove that the modules can walk the walk.

The bifacial modules will make up part of a 205 kW system, which is being installed on the rooftop of the university’s Weinstein Center for Recreation and Wellness, in Virginia. It is the first time that SolarWorld’s Bisun solar panels are being installed for commercial use in the Americas.

Perhaps the project’s most interesting aspect is that the modules will be installed alongside standard mono-facial modules with the same cell architecture in order to produce real-time performance data comparisons.

On top of this, the two types of modules will be installed on both a gravel roof and one made of thermoplastic olefin, which is a white material similar to vinyl, for further comparative analysis. “Aside from making the university greener, this installation will provide a strong set of performance data in a real-world application,” said Mukesh Dulani, US president of SolarWorld.

SolarWorld’s Bisun modules are based on PERC technology. They are two-sided, so that they can generate energy from reflected light on the backside of the panels. The efficiency and yield of the backside depends on their distance from the surface and the material of the surface.

SolarWorld believes that the technology can generate 25% more energy compared with mono-facial modules, thus significantly lowering the costs of power generation per kWh. “Bifacial PERC modules represent a significant technological advancement in photovoltaics, and SolarWorld is once again leading the deployment of cutting-edge solar technologies,” added Dulani.

The installation is expected to be completed this spring.
