Abstract

Rapidly and remotely monitoring and receiving the solar cell systems status parameters, solar irradiance, temperature, and humidity, are critical issues in enhancement their efficiency. Hence, in the present article an improved smart prototype of internet of things (IoT) technique based on embedded system through NodeMCU ESP8266 (ESP-12E) was carried out experimentally. Three different regions at Egypt; Luxor, Cairo, and El-Beheira cities were chosen to study their solar irradiance profile, temperature, and humidity by the proposed IoT system. The monitoring data of solar irradiance, temperature, and humidity were live visualized directly by Ubidots through hypertext transfer protocol (HTTP) protocol. The measured solar power radiation in Luxor, Cairo, and El-Beheira ranged between 216-1000, 245-958, and 187-692 W/m2 respectively during the solar day. The accuracy and rapidity of obtaining monitoring results using the proposed IoT system made it a strong candidate for application in monitoring solar cell systems. On the other hand, the obtained solar power radiation results of the three considered regions strongly candidate Luxor and Cairo as suitable places to build up a solar cells system station rather than El-Beheira.

Abstract

This paper discusses the improvement of the storage system by getting a stable voltage, with a large inrush current for the battery. The battery system (BESS) is the most important component of a photovoltaic (PV) system. Its large size allows it to provide the desired high peak discharge currents and extend its lifespan. Our work focuses on control the integration of super capacitors (SC) with batteries in order to maximize the battery's power supply, reduce the ripples caused by light changes photovoltaic cells, improve the battery lifespan and supply the useful high peak power for a short periods of time for the big loads (like motors, trains, and big mechanisms,), Super capacitors (SCs) can do that since their internal architecture does not include chemical solutions, which will result in high power densities and higher charge and discharge currents, also lower energy densities. These lower energy densities will be compensated by a combination and integration with the battery, especially the lead-acid battery. Focusing on the lead acid due to drawbacks like short lifetime, low number of cycles. from that combination by switching the control circuit, it can increase the battery lifetime and remove the stress, especially in high current loads, reducing abnormal battery temperature, and ensuring a significant mass reduction of the energy storage system as all. Also, by supporting the SC with a buck boost converter control, keeping the voltage stable, preventing the PV voltage changing problems from the PV cell to any storage systems.
