At SolX Technologies, we don’t just host interns—we turn top academic achievers into real-world problem solvers. When standout students like Caitleen Stefani T. Chua from De La Salle University and Ralph Adrian P. Rafa from Mapua University step into our world, they don’t just participate—they power up. Armed with sharp minds and a knack for turning theory into action, they thrived in tackling real energy challenges.
Caitleen, a Summa Cum Laude and Best Presenter Awardee at the International Conference on Sustainable Energy and Green Technology, brought her expertise in sustainable design. Ralph, a numbers whiz with a strong grasp of engineering principles, approached complex energy challenges with precision. Together, they proved that engineering is more than just calculations—it’s about innovation, adaptability, and impact.
Their internship pushed them beyond the classroom. Site inspections were a reality check—climbing rooftops under the heat and solving on-site challenges tested their resilience.
“It was scorching hot, and I was nervous about the height,” Caitleen recalled. “But seeing the project take shape made everything click—this is real engineering.” Ralph also faced a steep learning curve: “At first, I struggled with bid analysis, but after working through real project data, I saw how critical these insights are in shaping energy solutions.”
They worked with industry-standard tools like PVsyst and SolarEdge, analyzed bids in the Renewable Energy Marketplace, and contributed to rooftop solar projects for Charter Chemical and Coating Corporation, Xavier School Nuvali, and Xavier School San Juan. Beyond analysis, they gained hands-on experience in project execution—from contractor sourcing to installation and final turnover. Under the mentorship of Robi Andres, ECE, PMP, Jeanuel Paje, RMEe, and Richard Julio, RMEe, they refined their technical expertise and gained real-world insights into the renewable energy sector.
Looking back, their perspective on engineering evolved.
“At first, I thought engineering was all about calculations. But real-world engineering is about problem-solving in unpredictable conditions, working with people, and adapting quickly,” Ralph reflected. Caitleen echoed this sentiment, sharing how her time at SolX turned theory into action:
"Even in just 300 hours, I learned so much. I refined my skills in solar sizing, post-installation assessments, and industry applications. Seeing our designs come to life and working alongside experts made this experience invaluable."
For Ralph, one of the most valuable lessons was understanding the full scope of project execution.
“From EPC sourcing and client relations to preparing TORs and conducting billing analyses, I saw firsthand how energy solutions are developed. Beyond the technical side, I also honed essential soft skills like communication and collaboration, thanks to my mentors' guidance and encouragement.”
Robi Andres, ECE, PMP, one of their mentors, shared his thoughts on their growth:
"Caitleen and Ralph came in with strong technical knowledge, but what impressed us most was their ability to learn fast, adapt, and think critically. By the time they completed their internship, they weren’t just learning from us—they were contributing real solutions.”
Caitleen and Ralph weren’t just interns—they were key contributors, proving that the next generation of STEM professionals is ready to take on industry challenges. As they move forward, their experience at SolX will serve as a strong foundation for their careers in renewable energy.
