Power decreases in crystalline silicon solar modules as temperatures rise, studies show

Most photovoltaic (PV) modules made with crystalline silicon are known to decrease by 0.5 percent per Celsius degree as the temperature increases, they say. Dr. Govindasamy Tamizhmani, president of TÜV Rheinland LLC, and Mr. Joseph Kuitche, operations section head of TÜV Rheinland PTL, plan to show the link among module temperatures and weather conditions. The results of the study, they continue, which was conducted at Arizona State University and TÜV 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.

It is scheduled to take place during this year’s Intersolar North America’s "Crystalline Silicon II – Modules & Systems" session on July 14.

Intersolar North America 2010, which is due to start tomorrow and will last until Thursady, is taking place in San Francisco, the U.S. This year about 550 international exhibitors, 20,000 trade visitors and 1,600 conference participants are expected to attend.
