About the IISE Solar Internship Program
A specialized 6-month technical training initiative bridging academic theory and renewable energy engineering practice.
Connecting Academic Knowledge to Clean Energy Realities
University engineering curricula across India provide excellent grounding in fundamental electrical circuits, thermodynamics, mechanics, and material sciences. However, when entering the fast-moving renewable energy sector, fresh graduates often discover a significant disconnect between textbook theory and practical site execution. The IISE Solar Internship Program was engineered specifically to bridge this gap.
As India accelerates toward ambitious renewable energy targets — driven by utility-scale solar parks, state net-metering policies, and national initiatives like the PM Surya Ghar Muft Bijli Yojana — solar EPC (Engineering, Procurement, and Construction) companies and project developers urgently require engineers who understand real components. They seek professionals who can conduct rooftop shading surveys, size inverter strings, review Single Line Diagrams (SLDs), audit electricity bills, and supervise electrical installation safely.
Over six structured months, participants progress through eight detailed technical modules. Digital study materials and self-paced video modules build rigorous analytical foundations, while instructor-guided classroom sessions and site-based demonstrations in the Mumbai metropolitan area provide crucial tactile exposure to inverters, panels, mounting structures, and testing instruments.
Institutional Credibility: IISE & Technical Partner CERT
The Indian Institute of Solar Energy (IISE) is a dedicated unit of CERMS India Foundation. Training design, curriculum validation, and technical certifications are delivered in partnership with the Centre for Energy Research and Training (CERT). This collaboration ensures participants receive rigorous, industry-relevant training aligned with actual industrial engineering standards across India.
