Schueco announced today that it has been working with UK company Flomerics’ Flovent computational fluid dynamics (CFD) software to redesign its products to improve their thermal performance so that 15% to 20% more modules can be used in a given space. Today’s photovoltaic panels present a major thermal design challenge since every degree Centigrade of temperature rise reduces the power produced by 0.5%.

“The CFD results helped us understand exactly how the panels were being heated and guided us as we made major improvements to the design,” said Hamid Batoul, Technical Director of Solar Department, Schueco International, Paris, France. “As the first in our industry to perform CFD simulation, we believe that we are now able to provide our customers with substantially higher power output than an equivalent competitive design.” 

Flovent simulates the absorption and reflection of solar energy by the panels, the transfer of heat to aluminum profiles and the surrounding air, etc. “The CFD results helped us understand exactly how the panels were being heated and guided us as we made major improvements to their design,” Batoul said. “Examining the flow of air under the photovoltaic panels showed that the size of the passageway was constricting the flow of air. We increased the depth of the profile that supports the photovoltaic panels to increase the distance between the panels and the roof. Re-running the simulation demonstrated that this increased the airflow and reduced the temperature of the photovoltaic panels. Through these studies, we optimized the design of the solar energy systems and also gained an understanding of how temperature is affected by different arrangements of panels and ambient conditions.”

The utility-scale PV market is poised for exponential growth and yet the industry still has many fundamental opportunities to improve on standards and best practice. Tracker shade loss has been one of those topics that deserve more attention, but has been typically handled by derate factors rather than trying to accurately forecast the loss over the life of the system. Join Nextracker’s subject matter experts, Aron Dobos and Neelesh Umachandran, and Rounak Kharait, director of solar energy assessments at DNV, for a webinar about why shade modeling matters and recommendations on what the solar industry should do about it.

Join us to hear directly from the CTOs and heads-of-research from the top-20 cell/wafer producers to the PV industry today. The event will focus on predicting the key metrics underpinning the next big shift to n-type with answers to the key questions: When will the transition to n-type happen? Which companies will be first to 10 GW capacity and production? Who will be the key equipment suppliers for the new production lines? Which n-type process flow/architecture will emerge as the front-runner? What will polysilicon purity and wafer thickness levels look like for optimized n-type manufacturing? What will the upstream poly/wafer supply-chain look like in 5 years from now?
