Frequently Asked Questions: Diploma vs PG Diploma in Solar

What is the core difference between a Diploma and PG Diploma in Solar Technology?

The Diploma in Solar Technology is an undergraduate foundational qualification (2 Semesters / 510 Hours) designed for 12th pass students, ITI holders, and non-engineers, focusing on physical installation, system sizing basics, safety, and O&M. The PG Diploma is an advanced 1-year postgraduate program designed specifically for engineering graduates (B.E./B.Tech), covering PVsyst simulation software, AutoCAD single-line diagrams, utility-scale EPC management, and project financial modeling.

Which solar course is suitable after Class 12th?

The Diploma in Solar Technology is the designated program for candidates who have completed Class 12 (from any stream—Science, Commerce, or Arts). It does not require a prior engineering degree and takes learners from fundamental electrical principles to practical rooftop installation and field commissioning.

Can an engineering graduate (B.Tech) apply for the Diploma in Solar Technology?

Yes, an engineering graduate is technically eligible for both programs. However, IISE strongly advises engineering graduates to enroll in the PG Diploma. The foundational Diploma curriculum covers basic electrical circuits and introductory PV concepts already mastered during engineering school, whereas the PG Diploma provides advanced software (PVsyst) and commercial management skills that qualify engineers for design office and project leadership roles.

What are the strict eligibility requirements for the PG Diploma in Solar Technology?

The PG Diploma requires a Bachelor’s degree in Engineering or Technology (B.E. / B.Tech) in any discipline (Electrical, Mechanical, Civil, Electronics, Energy, etc.). Final-year B.Tech students awaiting their final semester results and working engineers looking for an energy transition are also eligible to apply.

How long does each course take to complete?

The Diploma in Solar Technology spans 2 academic semesters (510 total training hours and 34 credits), which can be completed in a structured 6-month or 1-year timeline. The PG Diploma in Solar Technology is a full 1-year (12-month) intensive hybrid program combining weekend/evening lectures with a 5-day on-campus practical contact program (PCP).

Which course covers advanced solar system design and engineering?

Advanced solar system design is covered exclusively in the PG Diploma in Solar Technology. This includes string voltage calculations for temperature extremes, MPPT window matching, 3D near-shading construction, cable deratings, AC/DC switchgear selection, and transformer impedance matching.

Does either course include industry-standard PVsyst software training?

Complete mastery of PVsyst software is a core pillar of the PG Diploma in Solar Technology. PG students learn meteo data importation, 3D shading scene modeling, loss tree analysis, and bankable generation report synthesis. The foundational Diploma program only provides a conceptual overview without full software licensing workflows.

What practical hardware training is included in each program?

Both programs feature mandatory physical contact sessions at IISE’s specialized laboratories. Diploma students complete a 3-Day Practical Workshop focusing on panel mounting clamps, MC4 crimping, inverter wiring, and earth resistance testing. PG Diploma students complete a 5-Day Intensive Personal Contact Program (PCP) involving computer simulation labs, live array testing with IV curve tracers and thermal cameras, and microgrid BESS synchronization.

What career opportunities are available after completing the Diploma?

Diploma graduates typically enter the workforce as Solar Installation Technicians, Site Supervisors, Junior O&M Specialists, Field Service Executives, or Solar Sales Consultants. Demand is particularly robust among rooftop solar EPC contractors implementing residential systems under the PM Surya Ghar scheme.

What career opportunities are available after completing the PG Diploma?

PG Diploma graduates qualify for professional engineering office and management positions, including Solar PV Design Engineer, EPC Project Engineer, Renewable Energy Technical Consultant, Solar Asset Manager, or Independent EPC Venture Founder. Alumni work with leading developers, IPPs, and international consultancies.

What is the published fee structure for each course at IISE?

As published on the official IISE course catalogue, the Diploma in Solar Technology fee is ₹59,999/-. The PG Diploma in Solar Technology standard fee is ₹1,24,999/- (with early-bird and merit scholarship concessions starting at ₹79,999/-). Flexible milestone payment and no-cost EMI options are available through the admissions office.

Can working professionals pursue these courses while employed full-time?

Yes. Both programs are delivered through an accessible hybrid format. Theoretical lectures and software walkthroughs are conducted online during evenings and weekends. The mandatory physical contact sessions (3 days for Diploma, 5 days for PG Diploma) are pre-scheduled well in advance to allow employed candidates to plan leave accordingly.

How should students evaluate the return on course investment (ROI)?

Students should compare the course investment against starting salary tiers and career longevity. The Diploma (₹59,999) leads to starting technician/supervisory salaries of ₹2.0L–₹3.5L PA. The PG Diploma (₹79,999–₹1,24,999) leads to engineering design packages of ₹3.5L–₹5.5L PA, with rapid growth to ₹6.5L–₹10.0L+ PA within 3 to 5 years due to scarce PVsyst software mastery.

How can applicants contact IISE to confirm their individual eligibility?
