Under the patronage of Prof. Dr. Alia Abbas Al-Attar, President of the Northern Technical University, and the supervision of Prof. Dr. Omar Khalil Ahmed, Dean of the College,
the Department of Electrical Engineering Technologies at Al-Polytechnic College in Hawija organized a training course entitled “Renewable Energies and Their Practical Applications.”

The course was presented by:

Asst. Prof. Browen Raheem Kareem

Lecturer Alaa Ahmed Yas

The course was attended by a number of college staff members as well as external participants. It was one of the promotion-related courses, and a test was conducted for the participants.

The course covered:

The basic concepts of renewable energy, its types, and benefits, with a comparison between renewable and non-renewable energy sources.
It also included an explanation of the fundamentals of photovoltaic (PV) solar cells, their working principles, and the types of solar systems (On-Grid and Off-Grid).
The course addressed the components of solar systems such as panels, batteries, charge controllers, and inverters, in addition to methods of calculating daily load consumption and determining the number of panels required for residential systems.

The course also explained:

The methods of connecting solar panels (series/parallel), how to select suitable batteries and calculate their capacity, and the different types of batteries (Lithium, Gel, Lead-Acid) and their charging methods, as well as key protection measures.
Furthermore, the course discussed the function and types of inverters, common faults in solar systems, an introduction to wind energy and small household turbines, and how to read simple solar system schematics.

The course aimed to:

Enhance participants’ knowledge in the design, implementation, and operation of small and medium solar systems, and to develop their practical skills through hands-on applications, including connecting a solar panel with a battery and inverter, as well as a mini-project for designing a solar system for a rural home.
The course also emphasized the role of renewable energy in environmental protection and in raising public awareness about energy conservation.

The course concluded with the following recommendations:

1. The importance of expanding the use of renewable energy technologies in residential and service projects.

2. Encouraging students and researchers to conduct applied research in the fields of solar and wind energy systems.

3. The necessity of holding continuous practical workshops to train personnel in installing, operating, and maintaining solar systems.

4. Strengthening cooperation with electricity departments and the private sector to promote the culture of clean energy use.

5. Supporting student initiatives and entrepreneurial projects that rely on renewable energy to serve the community.
