Abstract

A line focusing concentrated solar distillation unit was developed and its techno-economic analysis was carried out using batch flow, continuous flow without and with tracking mechanisms. Physical quality parameters of feed and distilled water samples, water temperature at different points, performance analysis and estimated production of developed unit were examined. The examined quality parameters of distilled water were well below permissible limits. The water temperature inside the concentrated tube was in the range of 107.0˚C to 109.0˚C. The quantity of distilled water was observed to be inversely proportional to the amount of total dissolved solids in the water samples. The measured average daily and estimated lifetime yield from the developed unit during batch flow was 4.0 and 13,621.0 liters, for continuous flow without tracking 5.1 and 19,689.0 liters, and with tracking mechanism 5.7 and 21,758.0 liters, respectively. The continuous flow with tracking mechanism was found as best method for the production of distilled water. The total life cycle cost of the project was estimated to be PKR 62,144.00. The estimated unit cost of the distilled water per liter would be PKR 6.06 for continuous flow with tracking and PKR 9.69 for batch flow technique. ©2019. CBIORE-IJRED. All rights reserved

Abstract

­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­The aim of this study was to analyse the influence of temperature on electrical characteristics of crystalline and amorphous photovoltaic (PV) modules in outdoor conditions at Nawabshah. The experimental setup was made over the roof of the departmental building. The climatic conditions of site were recorded with the help of HP-2000 Professional Weather Station in three different timings of the day, i.e. morning, noon and evening. The electrical characteristics of the PV modules were recorded with Prova-210 and module temperatures with Prova-830. The maximum intensity of global solar radiation was recorded at noon and ambient temperature in the evening and the relative humidity in the morning hours. It was observed that amorphous module got 0.7°C, 1.0°C and 1.6°C more average temperature than polycrystalline, thin film and monocrystalline modules respectively. The average maximum measured open-circuit voltage was noted from amorphous with 96.7% and minimum from thin film with 81.3% of their respective values on standard conditions, whereas, the average maximum recorded short-circuit current was produced by thin film with 64.9% and minimum by amorphous with 51.4%. The average maximum power was produced by polycrystalline and minimum by amorphous module. It was discovered that the crystalline PV modules gave more fill factor than thin film and amorphous module.Article History: Received January 6th 2018; Received in revised form May 5th 2018; Accepted May 26th 2018; Available onlineHow to Cite This Article: Jatoi, A.R., Samo, S.R. and Jakhrani, A.Q.

Abstract

The purpose of this study was to evaluate the influence of module temperature on the efficiency of polycrystalline (p-Si), monocrystalline (m-Si), amorphous (a-Si) and thin film photovoltaic modules at outdoor environment of Nawabshah city Pakistan. The experimental setup was made and installed over the top roof of departmental building. Weather conditions, such as global solar radiation, ambient temperature, wind speed and relative humidity, power output and temperature of all selected four types of module technologies were measured at the site by logging data. Then, the logged data was normalized because of different rated power of photovoltaic modules for comparison purpose. Results revealed that less temperature impact was noted from thin film module and thus it gave more normalized power with 45.6% among other examined modules. On the basis of overall efficiency, p-Si, m-Si, a-Si and thin film modules gave 92.4%, 93.7%, 94.4% and 95.4% yearly average normalized efficiencies respectively. It was found that temperature has more impact on the efficiency of other examined modules compared to thin film modules. Thus, it is concluded from the study that thin film module is better in outdoor environment of Nawabshah
