Running Cum Laude Earlfred Cortez Finishes Internship at SolX Technologies

At SolX Technologies, internships are designed not just to train but to transform—preparing outstanding students for the real and demanding work of an engineer, both on-site and behind the scenes. That’s exactly what running Cum Laude Earlfred Wendel Cortez, a Bachelor of Science in Electronics Engineering student from National University and graduate of Caloocan National Science and Technology High School, experienced during his 300-hour solar internship.

Earlfred entered the program with academic excellence and the drive of a true NU Bulldog. He left with something even more valuable: industry readiness, shaped by real-world experience and a deeper understanding of the challenges and opportunities within the energy sector.

Under the guidance of Engr. Robi Andres, ECE, PMP, developed not only technical competence but also the determination and curiosity required of a future engineer. “Before this internship, I only knew the theories,” Earlfred shared. “I expected to learn about the technical aspects—like parts, installations, and the basics of solar PV systems.

But at SolX Technologies, I gained so much more. I was exposed to real tools and industry-standard platforms like PVsyst and SolarEdge. I learned how to simulate solar designs, forecast energy savings, and evaluate actual system performance. It wasn’t just software work—we did site visits, checked system outputs, and even troubleshooted breakers and voltage levels.”

He continued, “I also saw how technology and engineering come together. That’s really the heart of SolX operations. I was exposed to engineering, procurement, and construction (EPC) firms and even participated in the vetting process for projects up to 2MW.”

“What stood out to me,” he added, “was how SolX connects EPCs to its platform to bid for projects while also guiding clients to understand how solar PV systems can significantly impact their operations. These systems can cover up to 40% of the energy demand of the industrial and commercial clients we support—and being part of that journey was incredibly eye-opening.”

Beyond the technical work, Earlfred joined external learning sessions arranged by the SolX team, including the Solar & Storage seminar and a TESDA-sponsored vendor training. These added experiences broadened his perspective and practical knowledge.

He was immersed in the entire project cycle, from drafting terms of reference and evaluating installation sites to analyzing system performance. Earlfred also collaborated with fellow interns Louie and Migs from Mapua University and Lyceum of the Philippines University - Cavite on monitoring the daily production of existing solar systems, performing data cleaning, and preparing reports on post-installation results and savings.

What surprised him most was the company culture.

“I thought it would be intimidating and super strict,” Earlfred said. “But I found a professional yet warm culture here—collaborative, encouraging, and very hands-on. The team really welcomed us, and being around NU seniors gave me even more confidence.”

For Engr. Robi Andres, mentoring interns like Earlfred is both a responsibility and a privilege.

“I’m proud to host and train outstanding interns who are open to learning and show maturity beyond their years,” Andres said. “Thank you to National University for honing students like Earl, who are eager to grow and make a difference.”

SolX’s internship program is more than just a learning experience. It builds critical thinking, adaptability, and leadership. Earlfred’s time with the team gave him the tools and mindset not just to thrive in the industry, but to help shape its future.

To institutions like National University that continue to entrust us with their brightest minds, thank you. At SolX Technologies, we remain committed to guiding the next generation of engineers, one bold intern at a time.
