Francis Carl O. Villalino is a third-year Electrical Engineering Student from the Eastern Visayas State University, who recently completed his internship with the Institute for Climate and Sustainable Cities – RE-Charge Pilipinas team in Tacloban City.

When I began my internship at ICSC’s RE-Charge Pilipinas (RCP), I knew the environment would be both challenging and enriching. ICSC is renowned for its commitment to sustainable energy solutions, and I was eager to immerse myself in their work. 

As an aspiring Electrical Engineer, I’ve always been eager to gain hands-on experience in my field, especially on renewable energy. I had a basic understanding of electrical systems from my studies, but my knowledge of solar energy and its applications was admittedly limited. I entered this internship with the hope of bridging this gap, gaining practical experience, and learning from experts in the field.

One of the most important aspects of my time at RCP was the mentorship I received from the team. Sir Glinly Alvero, Sir Orlando Quesada, Ma’am Jessa Margallo-Zosa, and Sir Arturo Tahup were instrumental in my development; they supported us through the process, and encouraged us to think critically, work together, and foster an environment of respect and learning.

Sir Glinly, in particular, was very patient and dedicated to teaching. He explained complex concepts in a way that was accessible and engaging, ensuring that we understood both the theory and its practical applications. In one-on-ones, group workshops, and hands-on projects, Sir Glinly was always there for guidance and support. His mentorship extended beyond technical skill; he also emphasized professionalism, teamwork, and ethical responsibility in our work.

As part of our training, we were required to conduct assessments and share our knowledge with others, including peers and supervisors. The thought of presenting in front of a large audience was daunting; I had never spoken to such a diverse group of people before, and the pressure of delivering accurate and valuable information weighed heavily on me. 

During my first presentation, which focused on the crucial topic of solar energy, hazards, and safety protocols, I found myself stumbling over words and struggling to maintain composure. However, my mentors reassured me that making mistakes was part of the learning process and encouraged me to keep practicing. With their encouragement and feedback, I gained confidence, and felt more at ease and able to articulate my points more clearly by the second presentation. This taught me the importance of preparation, practice, and adapting to different audiences—skills that are valuable both in public speaking, and in my future career as an engineer.

The practical aspect of my internship was equally enriching, as we had many opportunities to engage in hands-on learning. One of the most memorable projects was the installation of solar charging stations at the Kapuso Village Integrated School (KVIS), which required a deep understanding of both the technical and safety aspects of solar energy.

Under Sir Glinly’s guidance, we were taught the intricacies of solar panel installation, from calculating the appropriate wattage for different components to understanding the system’s layout and design. We learned how to select and connect inverters, solar chargers, batteries, and wiring—all essential components for a functional and efficient solar power system.

Another highlight was working on the TekPak: a portable, solar-powered device designed to provide reliable electricity during emergencies. The TekPak is a testament to ICSC’s innovative spirit, combining practical design with cutting-edge technology. Being involved in this project allowed me to apply my theoretical knowledge in a real-world context, giving me a deeper understanding of the importance and impact of renewable energy solutions.

Through my internship, I gained a profound appreciation for renewable energy, particularly solar power. ICSC emphasized the environmental and societal benefits of shifting from traditional energy sources, like coal, to sustainable alternatives. I learned how solar energy harnesses the power of the sun to provide clean, affordable electricity, which reduces our reliance on fossil fuels and its harmful effects on the environment.

My internship with ICSC-RCP has had a lasting impact on my perspective as an engineer-in-training; I am now more committed to pursuing a career that contributes to the advancement of renewable energy technologies. The knowledge and skills I’ve acquired will play a crucial role in my future endeavors, whether in studies, research, or professional practice.

Interning at RE-Charge Pilipinas has been a transformative experience. The mentorship, experience, and opportunities for personal and professional growth have exceeded my expectations, and I’m grateful for the chance to learn from such a dedicated expert team. The confidence I’ve gained, along with new technical skills and insights, will serve as a strong foundation in my journey in Electrical Engineering.

I look forward to applying the lessons learned at ICSC in my career, and hope to contribute to the ongoing efforts to promote sustainable energy solutions. My time here has not only shaped my skills as an engineer but also deepened my commitment to making a positive impact on society and the environment.
