Temperature behaviour of different photovoltaic systems installed in Cyprus and Germany

The stabilizing effect of expanded graphite on the artificial aging of shape stabilized phase change materials

“…Silicon photovoltaics (PV) show a significant power drop when the panel temperature is above 25 C depending on the type of PV cell and the manufacturing technology [2]. The operating temperature reached by PV panels and associated power drop largely depends on the climate of the site.…”

Energy and Cost Saving of a Photovoltaic-Phase Change Materials (PV-PCM) System through Temperature Regulation and Performance Enhancement of Photovoltaics

“…Silicon photovoltaics (PV) show a power drop above 25 °C panel temperature with a temperature coefficient ranging from −0.3%/K up to −0.65%/K [1,2] depending on type of PV cell and manufacturing technology [3]. Various mathematical correlations have been developed to describe the dependence of PV operating temperature on climatic conditions and PV materials [4].…”

Optical and thermal modeling of a tilted photovoltaic module with sand particles settled on its front surface

“…C << 1 force convection, C >> 1 free convection, and C z 1 free and force convections. Finally, the open circuit voltage, V OC , and short circuit current of the PV module, I SC , are calculated based on the silicon temperature,T 1 , and the incident solar energy on the glass, I T,d , as [31]: a and b 0 are the temperature coefficients of current and voltage, respectively, T STC and I STC are the module temperature and incident solar radiation at the standard testing conditions, respectively. The electrical power of the PV modules at the maximum power point tracking is calculated as follows [31]:…”
