“…In the same way, thermal energy efficiency is obtained by dividing thermal energy stored by the solar energy incident on the PV panel given by Equation (9). Since the quality of thermal energy is not same as of the electrical energy, a conversion efficiency of 30% is used in Equation (9) to convert thermal energy into equivalent electrical energy:…”

“…A maximum PV operating temperature of 125 °C has been reported in southern Libya (27.6°N and 14.2°E) resulting in a 69% reduction in the nominal power [7]. The advisable operating temperature limit for PV ranges from −40 °C to 85 °C [8] however in hot and arid climates, PV temperature frequently rises above upper limit of temperature range [7], which results in temperature induced power failure as well as PV cell delamination and rapid degradation [9] urging a strong need for PV temperature regulation to maximize both panel power output and life. Different passive and active heat removal techniques have been used to maintain PV at lower temperatures.…”

Abstract:The current research seeks to maintain high photovoltaic (PV) efficiency and increased operating PV life by maintaining them at a lower temperature. Solid-liquid phase change materials (PCM) are integrated into PV panels to absorb excess heat by latent heat absorption mechanism and regulate PV temperature. Electrical and thermal energy efficiency analysis of PV-PCM systems is conducted to evaluate their effectiveness in two different climates. Finally costs incurred due to inclusion of PCM into PV system and the resulting benefits are discussed in this paper. The results show that such systems are financially viable in higher temperature and higher solar radiation environment. Keywords

“…It has been shown that PV cells degrade faster in hot climates due to long-term thermal ageing caused by their elevated operating temperatures (Kurtz et al, 2011). Additionally, PV modules lose structural integrity due to delamination that is caused by prolonged operation under elevated temperatures (Saly et al, 2001). By studying the physical mechanisms by which PV cells degrade, design modifications can be implemented to create longer lasting PV modules (Mathews et al, 2014).…”

It is assumed that similar PV modules are expected to perform equally well under the same atmospheric conditions, especially with regard to their rated output power. However, this is not always the case due to a number of factors, which include cell degradation overtime and cell manufacturing. It has been reported that PV modules within arrays need to be identical. This is required to have equal currents flow through the branches of an array in order to prevent power mismatches, hot spots and a lower overall output power. The purpose of this paper is to analyze the performance of three identical 10 W PV modules which were used over a 2-year period in a semi-arid region, in order to identify any anomalies. An experimental research design is employed where three identical 10 W PV modules were each connected to its own power loads that were to extract more than 90% of the rated power of the module over a 2-year period. A data logging circuit is included that provides power conditioning between the PV modules and an Arduino UNO board, which serves as the data logger. This logger relays the measured data to LabVIEW where the processing, display and recording is done. Two key anomalies that were identified relate to the abnormal degradation in output power of one of the modules and the abnormal improvement in output power when a newly manufactured module is introduced into the system.
