Enhanced heat dissipation of V-trough PV modules for better performance

A review on the thermal regulation techniques for non integrated flat PV modules mounted on building top

“…Solanki et al [38] presented a novel idea of cooling of solar cells in concentrator V-trough module in which a continuous metal sheet was used to construct the desired V-trough structure to support the reflector and act as heat dissipater. The surface area available for heat dissipation in the concentrator V-trough PV module with continuous metal sheet was 4 times higher than the case when Vtrough walls were not used for cooling.…”

“…Active thermal regulation methods for the control of temperature of PV module often employs (i) spraying of water on the top surface of the panel [12e14] (ii) jet impingement cooling [15] and (iii) passing air or water through channels or ducts [16e22]. The various passive thermal regulation methods adopted for the control of temperature of PV module include (i) immersion of PV module in dielectric medium [23] (ii) submerged water cooling [24,25] (iii) air flow induced by buoyancy [26e28] (iv) winddriven roof top turbine ventilator [29] (v) heat dissipater/heat sink [30] (vi) phase change materials (PCM) [31e33] (vii) evaporative cooling technique [34] (viii) cotton wick cooling [35] and (ix) expansion of stored gas to spray water [36]. Table 1 shows the summary of the review of the previous research works on cooling of PV modules.…”

A Combined Optical, Thermal and Electrical Performance Study of a V-Trough PV System—Experimental and Analytical Investigations

“…Paraffin wax was employed as the phase change material (PCM) having 56-58 °C melting range and was integrated at the rear side of the module to absorb the excess heat. In 2008, a V-trough PV system was designed to effectively dissipate the enhanced heat of the PV module for better performance [25]. In this design a single aluminum metal sheet frame that incorporated six rows of mono-crystalline Si cells mounted on six V-trough channels was used to achieve a better heat dissipation from the cells under concentration conditions.…”
