Investigations of the instantaneous performance of a solar chimney power plant installed in Aswan using IoT

Abstract

Although solar chimney power plant (SCPP) has a promising potential to convert the solar energy to electric power, greater efforts are needed to ensure its successful commercialisation on a large scale. The main obstacles with regard to the large-scale applications of SCPP are its efficiency, bulk size and dependency on solar irradiation. A comprehensive study on the integration of the Internet-of-Things (IoT) as a novel technique to monitor and hence improve its performance is presented. A small-scale SCPP is designed and constructed specifically for this purpose in Aswan, Egypt. The instantaneous performance parameters (temperature, solar intensity, wind speed, open circuit voltage, power etc.) were measured and further processed using IoT. The results show that IoT has a promising potential to enhance the performance of the system by providing a complete picture of the whole measurements. This is considered as a step forward for enhancing the technologies which will ensure the success of large-scale SCPP in the real world.

Experimental investigation of the performance of a single‐slope solar still under Aswan climate conditions

“…Because Aswan has long sunny days, the first value of the pyranometer was recorded at 5:15 am to reach the maximum value of about 1000 W/m 2 at noon. Subsequently, this reading dropped to zero at 7:15 pm, as shown in Figure 1, making it one of the rare cities with 14 h of sunlight [13]. Two traditional single-slope solar stills each of area 0.25 m 2 , identical slopes but with different gaps, were fabricated from wood and then placed to face the southern direction with 24 o , according to the latitude angle of Aswan [14].…”

“…The objective of this study was to evaluate the performance of a single-slope solar still under the climatic conditions of FIGURE 1 Monthly average solar radiation (2017) [13] Aswan city, and to examine the effect of the gap distance and ultrasonic atomization on the performance of the solar still. For this purpose, two similar single-slope wooden-frame solar stills were designed and tested.…”

Comprehensive Review on Renewable Energy Sources in Egypt—Current Status, Grid Codes and Future Vision

“…A real small-scale SCPP project was designed and constructed at the Faculty of Energy Engineering, Aswan, Egypt [27]. It comprises four main parts: WT, generator, tall tower, and air collector as shown in Fig.…”

“…5. Concentrated solar plant (CSP) is a type of solar thermal energy utilized to convey electricity by energy concentration by the sun in a single focal point [26], and is considered the foremost powerful and convenient option for its ability to outfit heat and electrical energy [27]. The minimum direct normal irradiance DNI for economically viable CSP plants at current rates is 2000 kWh/m 2 /y.…”
