Summary Compared with traditional photovoltaic‐thermal system, low concentration photovoltaic‐thermal systems install the low‐power concentrator (compound parabolic concentrator, Fresnel concentrator, miniature trough concentrator, etc) to improve system performance. In this paper, a baffle heat exchange channel was designed, which can decrease the temperature gradient of low concentration photovoltaic‐thermal module in the flow direction, based on the traditional flat‐box photovoltaic‐thermal collector. The system performance was monitored with different baffle spacing, flow rate, inlet temperature, ambient temperature, and radiation intensity by adopting simulation methodology. Furthermore, an experiment was performed to validate and evaluate the simulation results. The results indicated that, on a typical day, the maximum of thermal efficiency and electrical efficiency of the module were 55.11% and 12.50%, respectively.

“…Consequently, the efficiency and the life span of the module are curbed. For every 1°C rise in temperature, the efficiency of amorphous and crystalline silicon cell decreases by 0.25% . According to Kalogirou and Tripanagnostopoulos, this decrement is in the order of 0.45%, while Zhang et al find the decrement as 0.5%.…”

Summary A solar photovoltaic panel accumulates substantial amount of heat, which deteriorates its performance. Thus, to minimize the panel temperature, 3 new designs (semioval serpentine, circular spiral, and circular spiral semiflattened) of absorbers for back surface cooling are introduced in this paper. Experimental investigations on the panel performances with and without the designed cooling systems are performed. A similar experiment with an existing serpentine design of absorbers is also conducted, and the results of all the experiments are compared. The circular spiral semiflattened design absorber has shown preeminent performance among all the absorbers in terms of the highest improvement in efficiency (4.32%), fill factor (19.80%), etc.
