AIP Conference Proceedings [Author(s) SolarPACES 2017: International Conference on Concentrating Solar Power and Chemical Energy Systems - Santiago, Chile (26–29 September 2017)] - Techno-economic analysis of a small scale solar power tower at varied locations
摘要： Location selection is an important factor for the effectiveness and cost of a solar electricity generation system. Latitude and weather impact efficiency and availability, and local labor rates have a further influence on cost. To explore the impact of these effects, we performed techno-economic analysis of a small-scale solar power tower concept in six different locations in the United States, Australia, and India. The specific configuration we considered has a nominal power rating of 100 kWe and 5 hours of thermal energy storage. Further, we considered two deployment strategies: a single stand-alone 100 kWe tower, and a 20 MWe cluster of many towers. For each scenario, we used a probabilistic analysis method to evaluate levelized cost of electricity. We found that this configuration has potential for cost-competitive electricity generation and the ability to improve grid flexibility for integration of intermittent renewables. In addition, solar resource, latitude, and local labor rates all have an impact on the levelized cost of electricity of the system.

Energetic, economic and environmental (3E) analyses and LCOE estimation of three technologies of PV grid-connected systems under different climates
摘要： 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 kWp of polycrystalline (p-Si), 2.04 kWp of monocrystalline (m-Si) and 1.86 kWp 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 CO2 per kWp 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.

Economic analysis of water production from atmospheric air using Scheffler reflector
摘要： In this paper, the economics analysis of water production by using different solid desiccant materials and composite materials through Scheffler reflector is presented. The experiments for water production have been performed at National Institute of Technology, Kurukshetra, Haryana, India [29°58′ (latitude) North and 76°53′ (longitude) East]. The various factors have been carried out to calculate the annual cost/liter in Indian currency. Total six cases are studied, and for each case, uniform procedure is adopted. The silica gel gives the best economical annual cost/liter compared to molecular sieve and activated alumina in case of solid desiccant, and for composite material, it is CaCl2/River Sand compared to LiCl/River Sand and LiBr/River sand.
