What is SESI?
SESI, the Solar Energy Society of India, is a long-standing professional society for solar energy professionals in India. Founded in the 1970s, it pre-dates the major modern industry associations and has academic and research roots. Members include academics from IITs and universities, researchers from national laboratories (NPL, NISE, IISc), R&D professionals in industry, and students engaged in solar energy work.
SESI's primary role is professional and academic. The society organises technical conferences (the SOLARIS symposium being its flagship event), publishes proceedings, supports student programmes, and coordinates between academic institutions and industry on research and development matters.
SESI complements but does not duplicate the work of industry-focused bodies. NSEFI handles commercial industry policy advocacy. ISMA represents manufacturers. SESI focuses on solar science, education, and applied research. The three bodies operate in different layers of the solar ecosystem.
Why SESI matters
For Indian solar research, SESI provides the long-standing forum where academic and applied research is presented, peer-reviewed, and disseminated. SOLARIS symposia and other SESI events are where new research and applied innovations get visibility.
For students, SESI provides exposure to working solar professionals, conference participation, and networking that can launch careers in solar research or industry.
For applied research, SESI supports the bridge between academic work and industry application. Topics like cell efficiency, module performance modelling, advanced storage chemistries, and grid integration get cross-disciplinary attention.
For policymakers, SESI provides academic-research input on technical or scientific assessments, complementing industry-focused advocacy from NSEFI and ISMA.
How SESI operates
- Membership. Professional members from academia, research, industry R&D, and students.
- Conferences. SOLARIS symposium and other events organised periodically.
- Publications. Conference proceedings, technical reports.
- Student programmes. Support for student participation and presentations.
- Industry-academia coordination. Bridge between research and applied use.
- Policy input. Modest engagement on technical matters.
- International coordination. Engagement with global solar research networks.
Benefits of SESI engagement
- Research dissemination. Forum for Indian solar research.
- Student development. Exposure to working professionals.
- Cross-disciplinary engagement. Bridges academia and industry.
- Long-standing reputation. Established since 1970s.
- International coordination. Connections with global solar research.
- Technical depth. Focused on solar science and applications.
Limitations
Limited commercial influence. Industry policy advocacy is handled by NSEFI and ISMA.
Smaller scale than industry bodies. Fewer resources for major policy engagement.
Academic-centric. Industry participation is secondary.
Periodic event cycle. SOLARIS and similar events are not annual at fixed cadence.
Visibility is modest. Less public-facing than NSEFI or ISMA.

Common mistakes about SESI
- Confusing SESI with NSEFI. SESI is academic-research; NSEFI is industry policy.
- Treating SESI as an industry body. Primarily a professional society.
- Expecting SESI to drive commercial policy. That is industry-body territory.
- Skipping SESI for students. Useful entry point to solar professional ecosystem.
- Confusing SESI with SECI. Different organisations: SECI is government utility-scale agency; SESI is professional society.

Frequently Asked Questions
What is SESI?
SESI stands for Solar Energy Society of India. It is a long-standing not-for-profit professional society promoting solar energy science, education, and applications in India. SESI publishes research, organises technical conferences, and supports academic-industry coordination on solar topics.
How is SESI different from NSEFI?
SESI focuses on solar science, education, and applied research. NSEFI focuses on commercial industry policy advocacy. SESI has academic and research professionals as members; NSEFI is industry-led.
When was SESI founded?
SESI was established in the 1970s, making it one of India's oldest solar-focused organisations. It pre-dates the major industry associations and has academic and research roots.
What does SESI do?
Organises technical conferences and workshops, publishes research and proceedings, supports student programmes, hosts the SOLARIS (Solar Energy Society of India Symposium) and similar events, coordinates between academic institutions and industry on R&D matters.
Is SESI an industry body?
Less so than NSEFI or ISMA. SESI is more a professional society for solar energy professionals including academics, researchers, and applied practitioners. Industry participation is welcomed but not the primary focus.
Does SESI engage on policy?
Modestly. SESI sometimes provides academic-research input on policy matters, especially where technical or scientific assessments are relevant. Policy advocacy is not its primary role.
Who are SESI members?
Solar energy professionals: academics from IITs and universities, researchers from national laboratories (NPL, NISE, IISc), professionals in R&D roles in industry, and students interested in solar energy.
What is SOLARIS?
SOLARIS is the Solar Energy Society of India's flagship symposium, organised periodically. It brings together researchers, industry, and students for technical presentations and policy dialogues.
Does SESI publish journals?
SESI publishes proceedings and topical reports from conferences and workshops. Major peer-reviewed journals are published by other publishers; SESI's publications complement them.
How is SESI funded?
Through member contributions, conference participation fees, and occasional research grants. SESI operates as a not-for-profit professional society.
Can students join SESI?
Yes. Student membership is available and encouraged. SESI supports student involvement in solar research and applications.
How influential is SESI in Indian solar?
