2018
In a dynamic of protection of the environment and sustainable development, solar energy is one of the essential solutions to the energy problems of developing countries and to limiting greenhouse gas emissions. In this work, we compare the energy productivities of photovoltaic installations in four cities of two countries (Morocco and Burkina Faso). Government energy policies in both countries place a strong emphasis on solar photovoltaics. We then chose to make a detailed evaluation of the performances of the various photovoltaic technologies under various climatic conditions in these countries. PVsyst software is used to model the performance of a photovoltaic solar power plant connected to the 6kWc network (2kWc per technology) using three silicon-based photovoltaic technologies, namely: polycrystalline (pc-Si), monocrystalline (mc-Si) and amorphous (a-Si) in two cities per country. The comparative analysis included annual energy efficiency, performance ratio, annual energy densi...
This paper presents two grid-connected photovoltaic (PV) systems (monocrystalline silicon, c-Si; copper–indium–diselenide; CIS) situated on the rooftop of the solar lab building in the National University of Malaysia, southwestern Malaysia. Various parameters were used to analyze the system performance; including array yield, final yield, capacity factor, and performance ratio. The recordings were noted down under the actual climatic conditions for an entire year. The variables of energy cost and payback period were also considered to calculate the economic feasibility of the system. Variations in the final yield of CIS were as low as 2.98 h/day in July to the highest value of 4.31 h/day in March. The final yield for c-Si power plant ranged from 2.92 h/day in July to 4.14 h/day in March. The calculated capacity factors for CIS and c-Si power plants were 15.6% and 14.4%, respectively, in July as the worst value, and 21.12% and 20.2%, respectively, in March as the best value. In the case of CIS power plant, the performance ratio ranges from 63.8 in July to 84.12 in March, and for c-Si power plant, it ranges from 59.92 in July to 79.14 in March. The energy cost and the payback period of the suggested system were evaluated as 0.045 USD/kWh and 28.44 years, respectively. Finally, this study provides valuable information for those who are interested in PV system installation in the tropical zones.
Comparative Study of Performance of Three Different Photovoltaic Technologies
2016
In this project, simulation approach is used for the comparative analysis of different photovoltaic (PV) technologies, namely; poly crystalline, mono crystalline and thin film PV. The PVsyst industrial PV system planning software solution was selected to model and simulate the entire PV system. The meteorological data used in the study are compiled from National Aeronautics and Space Administration (NASA) worldwide meteorological database. The meteorological data include 22-year monthly and annual averaged insolation incident on a horizontal surface (kwh/m2/day) and 22-year monthly averaged air temperature. A hypothetical electric load demand data is used for the simulation. According to the results, the thin film PV gave highest performance ratio (PR = 61.8%) and highest energy yield per year of 5516.8 kWh/year. However, in comparing PV generation technologies, conversion efficiency is the most important parameter to be determined. The results showed that the array efficiency of th...
Objective: This study presents the outdoor performance of five solar photovoltaic (PV) systems with five different solar cell technologies (poly-crystalline (pc-Si)), mono-crystalline (mc-Si), Copper Indium disulfide (CIS) thin-film, Amorphous Silicon (a-Si), and Heterojunction Incorporating thin (HIT) film. Methods: The PV systems are installed on rooftop of buildings at the Kwame Nkrumah University Science and Technology, Ghana. The systems' energy output in 2014, module temperature as well as environmental data were collected and analysed. Results: The total annual energy delivered to the grid varies between 3133.2 kWh for CIS and 4572.1 kWh for pc-Si while the performance ratio varies from 48.84% (CIS) to 71.26% (for p-Si). The annual energy density ranges between 45.7 kWh/m 2 for CIS and 195.8 kWh/m 2 for HIT. The total actual energy delivered to the grid by all the systems in 2014 is 20.62 MWh. Conclusions: The performance data shows, that, the CIS technology is least suitable while p-Si is the most suitable solar PV technology for the site considered, followed by a-Si, HIT and mc-Si respectively. If space is a constraint, then, the HIT based system is most suitable solar PV technology for this site and potentially, sites with similar climate. Practice implications: The findings from this study are useful in identifying solar cell technologies that are appropriate for this location and provide useful information to policy makers and individuals about the performance of grid-tied PV system in Ghana.

The objective of this study is to investigate the effect of temperature and wind speed on the performance of five photovoltaic (PV) module technologies for different climatic zones of Pakistan. The PV module technologies selected were mono-crystalline silicon (MC); poly-crystalline silicon (PC); heterogeneous intrinsic thin-film (TFH); copper–indium–allium–selenide (TFC); and thin-film amorphous silicon (TFA). The module temperature and actual efficiency were calculated using measured data for one year. The actual efficiency of MC, PC, TFH, TFC, and TFA decreases by 3.4, 3.1, 2.2, 3.7, and 2.7%, respectively, considering the effect of temperature only. The actual efficiency of MC, PC, TFH, TFC, and TFA increases by 9.7, 9.0, 6.5, 9.5, and 7.0% considering the effect of both temperature and wind speed. The TFH module is the most efficient (20.76%) and TFC is the least efficient (16.79%) among the five materials. Under the effect of temperature, the actual efficiency of TFH is the lea...

Recently, solar energy is considered as the most promising renewable energy source, due to the availability and advancement of the solar technologies. This paper presents an extensive energy, economic and environmental analysis of 2.04 kW p of polycrystalline (p-Si), 2.04 kW p of monocrystalline (m-Si) and 1.86 kW p of amorphous on microcrystalline (a-Si/μc-Si) identical PV systems installed on the rooftop of 20 different institutional buildings, located in various Moroccan sites. Based on the analysis conducted, annual results are predicted with respect to hourly meteorological data and performance characteristics of each technology are examined using energetic, economic and environmental indexes (3E analysis). Daily simulation results were compared with actual recorded data for one of the geographical site (Meknes city) and good matching between simulated and recorded data has been achieved to prove its validity. The energetic analysis has shown that poly-Si modules surpassed the mono-Si and amorphous-Si modules in terms of performance, capacity factor and conversion efficiency. Besides, economic analysis has been conducted to determine the discounted payback period and levelized cost of electricity (LCOE) for 20 Moroccan cities and the results have shown that p-Si, m-Si and a-Si/μc-Si offered the 20-city average of 17.1, 21.6 and 28.6 years payback period, respectively. Moreover, LCOE has been determined for each city and the results reveal that p-Si, m-Si and a-Si/μc-Si types PV modules presented the average of 9.02, 10.13 and 12.53 cent€/kWh, respectively. Finally, the environmental analysis has revealed that average of 1.316, 1.286 and 1.051 tons of CO 2 per kW p can be reduced by adopting the p-Si, m-Si and a-Si/μc-Si PV modules in the studied locations. The findings confirm the potential of the examined technologies and elucidate specific conclusions for the practice of such systems under Morocco's climate.
