Photovoltaic thermal modules (PVT) are devices that can convert solar radiation to electricity and hot water. PVTs have been proposed as a renewable source for rural areas in Cambodia. In this study, we evaluated the performance of PVT modules in the Kampong Chheuteal Institute of Technology (KCIT) campus in Kampong Thom province. A mathematical model…
Use of phase change material (PCM) in water storage tank to generate tempera-ture stratification that could enhance performance of photovoltaic thermal (PVT) module was investigated by numerical simulation. A commercial PCM, filled in a set of 40 mm diameter spherical capsules contained in a 200-liter water storage tank was used and the storage was integrated…
Photovoltaic thermal (PVT) modules convert solar energy into electricity and heat. Unlike that of normal photovoltaic modules, the nominal operating cell temperature (NOCT) of PVT modules, which is used to evaluate the temperature and electrical power output, is unknown because it depends on the mass flow rate and inlet temperature of the working fluid in…
Nominal operating cell temperature (NOCT) was commonly used to evaluate photovoltaic (PV) module temperature and this term is provided by the manufacturer but in case of photovoltaic thermal module, the NOCT was not fixed and varied with the circulating fluid mass flow rate and its temperature. In this study, a novel approach on NOCT evaluation…
Use of phase change material (PCM) to generate temperature stratification in water storage tank coupled with unglazed photovoltaic-thermal (PVT) module for combined heat and power generation enhancement was investigated by experimental and numerical analyses. In the experiment, RT42 PCM having melting point of 38–43 °C was filled in a packed-bed of 40 mm diameter spherical…
