In-situ performance and degradation of three different photovoltaic module technologies installed in arid climate of Morocco
摘要： This paper presents the results of a first-time study on the long-term performance, degradation and cost analysis of three different PV module technologies - monocrystalline silicon (m-Si), polycrystalline silicon (p-Si), and amorphous silicon (a-Si) - installed in the desert climate of Errachidia, Morocco. It mainly aims to determine the most adapted module technology. The performance ratio (PR), degradation rate (Rd) and levelized cost of electricity (LCOE) indicators have been determined for each installed PV technology. Results revealed that p-Si technology exhibits the best performance with the highest PR of 82.54 ± 5.84 % compared to 82.24 ± 4.77 % for m-Si and 81.36 ± 3.79 % for a-Si. However, the p-Si technology degrades faster with 0.92 ± 0.11 %/year compared to 0.45 ± 0.11 %/year for m-Si and 0.72 ± 0.11 %/year for a-Si. Thus, the generated energy and the calculated Rd of the investigated technologies are used for the LCOE calculation. Indeed, the lowest LCOE value is noticed for p-Si system with 10.32 c€/kWh compared to 11.15 c€/kWh for m-Si and 13.18 c€/kWh for a-Si.

Experimental performance assessment of a 2.25 kWp Rooftop PV system installed in the desert environment: a case study of Ghardaia, Algeria
摘要： The outcomes of an experimental study performed on a single grid-connected photovoltaic plant on the roof of parking are disclosed in the present paper. The PV system is located in southern Algeria (Latitude 32.26 N°, and longitude 03.46E°) at the Renewable Energy Applied Research Unit (URAER), Ghardaia, Algeria. This location is a desert and with a semi-arid climate. The performance results had been monitored for one year 2018. The present study aims to investigate the effect of seasonal variation on output parameters of PV systems. The results of some index parameters such as performance ratio (PR), array losses, system losses and yields (reference yield, array yields and system yields) are presented and discussed. Experimental results show that an essential variation in performance parameters has been seen for different seasons. The results show the maximum energy generated, reference yield, array yield, final yield, capacitor factor, capture and system losses in summer were 307,11 kW h/kWp, 5,35 kW h/kWp/day, 5,01 kW h/kWp/day, 4,74 kW h/kWp/day, 20,17%, 0,34 h/day and 0,27 h/day, respectively, while the maximum value of performance ratio (PR) was observed in winter (93, 06%). The grid is fed with a power of 3327, 15 kWh along the year.

AIP Conference Proceedings [AIP Publishing TECHNOLOGIES AND MATERIALS FOR RENEWABLE ENERGY, ENVIRONMENT AND SUSTAINABILITY: TMREES19Gr - Athens, Greece (4–6 September 2019)] TECHNOLOGIES AND MATERIALS FOR RENEWABLE ENERGY, ENVIRONMENT AND SUSTAINABILITY: TMREES19Gr - Modeling and experimental study of the performance of two photovoltaic technologies under arid climate
摘要： This paper presents a comparison of two mathematical models of photovoltaic modules, namely: a Real Photovoltaic model and an Improved Photovoltaic Model. These models were evaluated to test their accuracy and predict electrical performance, for the purpose of selecting the suitable model under arid climate conditions. An experimental study using two PV technologies mounted in an outdoor setting, namely amorphous silicon (a-Si) and polycrystalline, is then conducted to validate the mathematical model. Results show a good agreement between experiment and simulation using the improved model for the both PV technologies that adequate to simulate the PV production of two technologies under arid climate, a with good coefficient of determination equaling 0.9672 for the polycrystalline and 0.9957 for amorphous technology. This validation represents a useful tool for researchers in this field and for professional use cases in this location.
