The performance of crystalline silicon declines amid rising temperatures of rooftop modules.

The performance of crystalline silicon – widely considered a reliable solar module construction – declines amid rising temperatures of rooftop modules, according to studies performed by TUV Rheinland PTL, LLC, a member of the world’s largest solar and photovoltaic testing network.

Most photovoltaic modules made with crystalline silicon are known to decrease by 0.5 percent per Celsius degree as the temperature increases. Dr. Govindasamy Tamizhmani, president of TUV Rheinland PTL, and Mr. Joseph Kuitche, Operations Section Head of TUV Rheinland PTL, plan to show the link among module temperatures and weather conditions. The results of the study conducted at Arizona State University and TUV Rheinland PTL have the potential to impact the type of module set-ups homeowners and businesses choose to install in the future.

The presentation will cover the types of weather conditions influencing the module’s operating temperature and the thermal models developed to predict the temperatures of open-rack and rooftop crystalline silicon photovoltaic modules.

The 20-minute presentation will happen during Intersolar North America’s “Crystalline Silicon II – Modules & Systems” session on July 14 from 9 a.m. – 1 p.m. at the Intercontinental Hotel, 888 Howard Ave., San Francisco, Calif.
