Cooling PV modules with passive technique based on finned heat sink
A Pakistani research team has assessed the performance of a passive heat sink cooling technique in two different configurations: one using rectangular fins and one based on circular fins. The rectangular configuration was the best in terms of heat rejection. Modules mounted with this solution had a 6 C lower temperature than modules without cooling systems.
New technique to determine best cooling technique for solar modules
A new paper published by researchers at Malaysia’s Multimedia University provides a new method to assess the effectiveness of different cooling systems for photovoltaic modules. The proposed technique relies on measuring the output of the module with added cooling and comparing this to its power rating under standard test conditions.
New material for radiative cooling of solar panels
Spanish researchers have discovered a material said to offer radiative cooling and self-cleaning of devices which undergo critical heating during operation, such as PV panels. The thermal emitter enabled the scientists to lower the daytime temperature of silicon wafers by 14 degrees Celsius.
Waste heat is not cool, say US scientists
Engineers at the University of Utah have developed a tiny device which they say could increase the performance of PV panels and other electronic devices by converting energy lost as heat back into electricity.
Sungrow on the MENA market: “Of course, the bigger, the better”
Having equipped a three-digit MW volume of large scale and distributed generation projects throughout the region, Sungrow is ready for a rapid regional expansion. EMEA general manager Derek Huang told pv magazine at the World Future Energy Summit about his expectations across all market segments.
