Lowering solar module temperatures with radiative cooling, heat pipes
Chinese scientists have developed a hybrid cooling technique to reduce module temperatures by up to 12.86 C and increase power yields by 7.25%. Their system features a PV module and a separate RC module, integrated with a flat plate heat pipe in between.
Water-based cooling technique for photovoltaic-thermal systems
The novel technique consists of a PVC pipe with 20 holes that is placed on the top of a PV module and is able to maintain a constant discharge of water. It was demonstrated on an experimental photovoltaic-thermal PV system in which the PV panel was not integrated with the solar collector but connected to it via pipes.
