Solar-Based Hybrid Energy Systems for Continuous Power Supply in Isolated Regions

Electricity considered one of the most important forms of energy and is essential for the development of societies and for daily human life, serving as a way of living. In the economic and industrial sectors, it is a fundamental element. However, the lack of electricity in isolated areas where it is unavailable poses a significant challenge and a real obstacle to the development and growth of these regions. In this context, solar energy emerges as an alternative source of electricity and a viable solution to conventional power grids, which are often expensive to install and technically complex, especially in desert regions. Solar energy represents an excellent and reliable option due to its wide availability, low operational costs, and its safe and environmentally friendly nature.

This theoretical study aims to analyze the use of solar energy through a hybrid system and its application in powering telecommunication equipment. The system provides a reliable electricity supply and operates electrical devices, helping to overcome the isolation of remote areas and connecting them to the wider world.

This research adopts and is based on an analytical and theoretical methodology for the use of solar energy through this hybrid system, specifically designed to power telecommunications equipment in remote areas and to ensure the continuity and reliability of electricity supply. The study relies on a conceptual and analytical approach to guarantee the efficiency and long-term operational reliability of this hybrid system.

This hybrid system consists of several integrated components that work together to ensure continuous power supply, including:

-Solar panels, which must have high efficiency (e.g., 300 W / 39 V / 10 A). The number of panels depends on the required energy demand, as they represent the primary and main energy source for operating equipment during daytime.

-Batteries, which ensure energy storage and enable equipment operation during nighttime or in periods of prolonged solar radiation unavailability. These batteries should have high capacity (e.g., 2 V / 650 Ah), and their number depends on the required load consumption.

Electric generator, which guarantees power supply in the event of a system failure. It must have sufficient capacity, for example 35 kVA or higher.

-Power cabinet, considered one of the most critical components, as it manages and controls the entire system and regulates the operation and consumption of all components. It is a smart unit containing electronic equipment, intelligent control interfaces, protection circuit breakers, and power distribution units. The most important component within it is the FSU (Field Supervision Unit), which acts as a communication controller. It includes digital inputs and outputs (DI/DO), communication ports such as RS485, CAN, RS232, USB ports, and 5G/4G antennas.

The FSU collects data, enables monitoring and remote control via an IP address, and connects these isolated systems to the Internet.

This entire system ensures continuous electricity availability in remote areas, reduces fuel consumption and the use of environmentally unfriendly resources, and minimizes harmful greenhouse gas emissions.

This research is of significant importance as it addresses a major problem and provides a solution to economic and social development challenges in remote and isolated regions.
