Abstract

Arabian desert areas are suffered from high mitigation in the produced photovoltaic (PV) power due to high dusty weather. This article presents a robotic cleaner that will significantly reduce the impact of dust on the installed PV systems in these areas. The proposed robotic cleaner is simple, low cost, standalone, self-powered, portable, and connected to the cloud. ESP32 used as a controller that manages the cleaning process and monitors its PV power production, the battery's state of charge, time of the day, and weather conditions. Thanks to the ESP32 features and its ability to connect to the cloud, as an internet of things (IoT), via the ThingSpeak website. All the electrical, mechanical, and electronic design aspects are presented and implemented in this article. The results show the effectiveness and performance enhancement due to periodic cleaning using the proposed robotic cleaner. The results also show that the total percentage of the monthly normalized accumulated losses for the two scheduled cleaning photovoltaic strings with a performance improvement of 15.54% for the weekly cleaned string (WCS) 83.04% for the never cleaned string (NCS) through the tested month.

Abstract

In the last decades, researchers have widely discussed the effects of magnetized water on many biological and industrial aspects; many studies have also examined the effects of magnetization on water physical and chemical properties and shown a slight increase in the water pH level for the drinking water after magnetizations. This article presents a new practical model to magnetize the tap drinking water with permanent, and adjustable magnets to ensure fast and precise results. A new smart system is designed and implemented to calculate the required magnetic flux density, and the exposuretime based on the difference in the measured pH level of the water atthe inletand outlet pipes.Three permanent magnets, with magnetic flux densities of 500, 1000, and 1500 Gauss (G), are installed at different pipe routes, with added to a variable magnet on the main water outlet. The results show a promising prototype that is not only processing the water efficiently but also supply much data about the water properties, which can be led to more findingsin this field.
