Abjective. The stability and ecological cleanliness of energy sources are of crucial
importance for the effective operation of communication systems. Today, in addition to
traditional energy sources, renewable energy sources such as solar and wind energy are being
considered as effective and ecologically clean alternatives for powering communication systems.
This paper discusses the importance of solar and wind energy in communication systems,
as well as the integration of these energy sources with advanced technologies and innovations.
Keywords: Solar, wind, technological innovations, climate change.
A solar energy supply source converts the light energy from the sun into electrical
energy. The energy produced by solar power sources not only provides energy to communication
devices but also charges accumulator batteries. The charge and discharge processes of the
accumulator are monitored with the help of a measurement control device. Communication
devices that consume alternating current (AC) are connected through an inverter, while those
consuming direct current (DC) are connected directly to accumulator batteries. Solar energy
supply systems are divided into three main types: On-grid, Off-grid, and Hybrid. Currently, solar
energy sources of the On-grid, Off-grid, and Hybrid types are widely used in the energy supply
of communication systems in the Republic. The structure of the Off-grid type energy supply
source is shown in Figure 1.
Figure 1.
Structure of Off-grid solar energy supply source.
Here, DC→AC inverter converts direct current to alternating current; DC load (48 V)
refers to communication devices with direct current load; AC load (220 V, 50 Hz) refers to
communication devices with alternating current load. Based on observations, it can be stated that
the use of solar energy sources is more effective during the months of April to September
compared to the remaining months of the year.
Wind Energy Supply Source.
Due to the geographic location of our country and the
complex climatic processes occurring in the atmosphere, wind energy has a seasonal nature. The
average comparative power of wind flow across the country is 84.0 W/m², ranging from 20.0
W/m² in Andijan province to 104.0 W/m² in Navoi province.

According to Uzbekistan's 2017-2021 energy program, the renewable energy resources
have been identified, and the wind speed in stations designed for Uzbekistan’s climatic
conditions is estimated to generate 2.22 million tons per year, determining the wind energy
potential. The structure of autonomous wind energy supply sources used in communication
systems is shown in Figure 2.
Figure 2. Structure of wind energy supply source.
Wind energy sources can be used in both mixed and autonomous forms. The autonomous
wind energy supply source shown in Figure 2 converts wind energy into electrical energy.
According to research results, the use of wind energy sources is more effective during the
months of January, February, March, April, as well as October, November, and December,
compared to other months. During these months, the use of wind energy sources for continuous
power supply to communication devices requires 2-3 times more wind energy than in other
months.
Conclusions:
The energy supply of communication systems is one of the most important and urgent
issues. Today, solar and wind energy, as renewable sources, are widely used as alternatives to
traditional energy sources. These energy sources play a significant role in ensuring ecological
cleanliness, minimizing environmental harm, and creating a sustainable energy supply. The use
of solar and wind energy not only helps ensure the reliable and continuous operation of
communication systems but also contributes to reducing energy costs and combating climate
change. Additionally, the development of these systems plays a vital role in addressing the
global energy crisis.
