Effect of Unglazed Transpired Collector on the Performance of a Polycrystalline Silicon Photovoltaic Module

Abstract

The electrical power generated by a polycrystalline silicon photovoltaic (PV) module mounted on an unglazed transpired solar collector (UTC) has been studied and compared to that of a PV module without UTC for a quantitative analysis of electrical output and its role in reducing the simple payback periods of photovoltaic electrical systems. A 75W polycrystalline silicon PV module was fixed on an UTC in front of the ventilation fan, and effectiveness of cooling by means of the forced ventilation at the rate of 160CFM was monitored. The temperature reduction under forced ventilation was in the range of 3-9°C with a 5% recovery in the electrical output power on a typical day of the month of February 2005. The simulated and measured electrical power outputs are in reasonable agreement with root-mean-square error of 2.40. The life cycle assessment of a hypothetical PV system located at Daejeon, South Korea and consisting of 3kW PV modules fixed on a 50m2 UTC shows that with a possible reduction of 3-9°C in the operating temperatures, the system requires three 75W fewer PV modules. The simple payback period of PV system is reduced from 23yearsto15years when integrated into an UTC air heating system.

Flat-plate PV-Thermal collectors and systems: A review

“…However, the project was terminated prematurely when it was decided that Solarwall as a Canadian company could not apply for PV:BONUS grants. In a cooperation with KIER, an evaluation of the perforated collector with c-Si PV is presented by Naveed et al [240].…”

“…Naveed et al [240] examined a PVT air system in which PV was connected to an unglazed transpired collector. It was found that a temperature reduction of 3-9 1C resulted in an improved electrical performance, allowing a reduction in PV area from 25 to 23 m 2 .…”

Transpired solar collectors for ventilation air heating

“…In one study, the forced ventilation of polycrystalline silicone PV modules using a TSC system was able to reduce the operating temperature of the PV modules by 3-98C. This cooling of the PV modules resulted in a reduction in simple economic payback time from 23 years (PV without TSC) to 15 years (PV/TSC) (Naveed et al, 2006).…”

“…The aim of creating a hybrid PV/TSC system is to develop a device that can simultaneously convert solar radiation into economical heat and electricity when available collector area is at a premium (Charalambous et al, 2007), or simply to improve the economic performance of the PV system by cooling the PV cells (Naveed et al, 2006). There are two broad types of PV/TSC g bonded type -PV cells/modules are bonded directly to the absorber (Delisle, 2008;Hollick, 1998) g fixed type -PV modules are fixed to the absorber (CEI, 2010b;Naveed et al, 2006).…”
