Abstract (sommario):
Abstract: The Parabolic Concentrator (CPC) is a uniform photovoltaic thermal (PVT) compound linked to solar photos (N) of water collectors called PVT-CPC Active Solar Filtration System Analysis. New Delhi Analysis is done for a solar filter system for a given particle size under weather conditions. We assess efficiency, system productivity, and life cycle cost analysis. The Thermal Model Life cycle cost efficiency (LCCE), designed for LCCE analysis, is considered the only and double-doubled effective PVT-CPC system for filtering solar energy recovery time. In this work, we need to analyze the appropriate points of the collector and extract the bulk of the system. Tests were performed on dual-solar and dual-inclined PVT-CPC operating systems with a single basin size and a water depth of 0.14 m, with yield on yearly basis, factor of energy payback, and efficiency of life cycle cost conversion analysis of 5.0%, 12.63%. Moreover, 22.21% is two times higher than the solo inclined system. In addition, the water return, one PVT-CPC, and two turns have been found to have a recovery time (EPT) with an interest rate of 5%. The solar filter system is 10.89% and 17.99% higher than the solo inclined photovoltaic thermal compound parabolic concentrator activated solar filter system, respectively. The above analysis concluded, we can confirm that the two bends are better than the active PVT-CPC system for solar filtering, which is the only inclination of the depth of 0.14 m in water based on daily based analysis. If depth of water 0.14 m is more significant, for basin size provided the performance of one inline is improved and is better than curved solar-powered filtering systems. The upgraded system lasts longer and can meet potable water and DC electricity on sunny commercial days.

Abstract (sommario):
Abstract This paper presents performance analyses based on temperatures, thermal energy (overall), thermal exergy (overall), electrical exergy, and yield of the systems that have been investigated. In the present study, an analytical expression of N identical partly covered photovoltaic compound parabolic concentrator collectors connected in series (N-PVT-CPC-SS-HE) with an active single slope solar distiller unit and helically coiled heat exchanger has been found. The performance analyses of the proposed system have been executed for 0.25% concentration of CuO nanoparticles for collectors (N = 4), and fluid-flow rate 0.02 kg/s in 280 kg mass of basin fluid. The system's performance is compared with a previous system of N identical partly covered photovoltaic flat plate collectors connected in series (N-PVT-FPC-DS-HE) with an active double slope solar distiller unit and helically coiled heat exchanger. The thermal energy is 112,109.1 kWh, thermal exergy 312.07 kWh, and yield 3,615.05 kg annually. It is found that daily enhancement in thermal energy of the proposed system with CuO nanoparticles compared with the previous system with various nanofluids CuO, Al2O3, TiO2, and water is found to be 16.75%, 51.13%, 61.82%, and 80.67% more significant correspondingly. The enhancement in yield of the proposed system is obtained for CuO nanoparticles greater than the previous system with CuO by 11.19%, Al2O3 17.2%, TiO2 26.25%, and water 32.17%. The electrical exergy is almost the same as the previous system.

Abstract (sommario):
This paper deals with the enhancement in exergoeconomic and enviroeconomic parameters for single-slope solar still by incorporating N identical partially covered photovoltaic thermal (PVT) collectors. Three cases: (a) single slope solar still incorporating N identical partially covered PVT flat plate collectors (FPC) (N-PVT-FPC-SS), (b) single slope solar still incorporating N identical partially covered PVT compound parabolic concentrator collectors (N-PVT-CPC-SS), and (c) conventional single slope solar still (CSSSS) have been taken to assess the improvement in various parameters. The various parameters have been computed at 0.14 m water depth, selected values of mass flow rate, and number of collectors considering four climatic conditions of New Delhi for each month of year. It has been concluded that N-PVT-FPC-SS performs best followed by N-PVT-CPC-SS and CSSSS on the basis of exergoeconomic and enviroeconomic parameters; however, CSSSS performs better than N-PVT-FPC-SS and N-PVT-CPC-SS on the basis of productivity measured in terms of ratio of monetary value of output and input. The kWh per unit cost based on exergoeconomic parameter is higher by 45.11% and 47.37%; environmental cost is higher by 65.74% and 90.02%; however, the output per unit input based on productivity is higher by 12.09% and lower by 26.83% for N-PVT-FPC-SS than N-PVT-CPC-SS and CSSSS, respectively.

Abstract (sommario):
In this paper, analytical expression for characteristic equation of double slope solar still (DS) included with series connected N identical evacuated tubular collectors (N-ETC-DS) has been developed. The derivation is based on fundamental energy balance equations for various components of the proposed system. The analytical result of the proposed N-ETC-DS has been compared with results reported by earlier researchers for the same basin area under similar climatic condition. It has been concluded that daily energy efficiency is higher by 23.90%, 26.45%, and 42.65% for N-ETC-DS than N identical partially covered photovoltaic thermal (PVT) compound parabolic concentrator collectors (CPC) integrated double slope solar still, N identical partially covered PVT flat plate collectors (FPC) integrated double slope solar still, and conventional double slope solar still (CDS), respectively, at 0.14 m water depth under optimized condition. Moreover, daily yield, exergy, energy and exergy efficiency have been computed.

Abstract (sommario):
The basin type active solar still with CuO nanoparticles has been investigated in the current study and energy, exergy analysis, energy matrices, exergoeconomic parameter, environeconomic parameter, and productivity has been presented. The prime objective of this design is to develop an energy efficient solar distillation system and produce potable water at a reasonable price. The single and double slope solar distillation systems N-PVT-CPC-HE with water loaded CuO nanoparticles have been studied in detail. A mathematical model developed for the proposed systems and life cycle cost analysis for single and double solar distiller units with N-PVT-CPC using a helically coiled heat exchanger with water loaded CuO nanoparticles has emanated out. The analysis of four different weather conditions viz type a, b, c and d days for each month of year has been done. Detailed computation of energy, exergy, and yield optimized at N=4 number of collectors and various parameters like cost of distillate, CO2 mitigation, carbon credit earned, environeconomic, productivity and exergoeconomic also have been computed. Generally, exergoeconomic parameters are computed by lost exergy per unit cost for the systems like mechanical, thermal, etc. as many researchers reported, while in proposed study to compute the exergy gain per unit cost because solar energy is free of cost available. Solar distillation is carried out at 0.14 m depth of water, N-PVT-Compound parabolic concentrator collectors and optimum flow rate for the composite climate condition of New Delhi, India. Water production cost in ₹/kg and $/kg has also been calculated. Solar distiller performance in terms of hourly productivity of distiller unit has for optimum number of collectors (N = 4), flow rate, and relative water depth have been determined. It has been concluded that double slope N-PVT-CPC active solar distiller unit with heat exchanger using CuO nanoparticles gives the best performance based on average energy, exergy, Page vii yield, cost of distillate, CO2 mitigation, carbon credit earned, environeconomic, productivity and exergoeconomic etc. Following contributions are made by annual analysis of the proposed systems with CuO nanoparticles. 1. Distillate cost is less for system-B than system-A. Annual distillate costs for 30 yrs at rate of interest 10% are 0.30₹/kg for system-B, 0.344₹/kg for system-A, and 0.338₹/kg for system-C. 2. System-A gives a higher value of carbon dioxide mitigation and carbon credit earned based on thermal energy and exergy. Mitigation per ton based on energy and exergy for system-A is 15.76% and 53.5% higher than system-B and system- C, respectively. 3. Annual productivity of system-B for 15, 20, 30, 50 years are 209.44%, 230.63%, 251.28%, and 262.04% respectively. 4. Exergoeconomic analysis based on exergoeconomic parameter (Rex) of the system-B for 15, 20, 30, 50 years are 0.0312, 0.0344, 0.03746, and 0.03906 kWh/₹, respectively.
