5. Sun Shines on India
- Solar Resource availability
- 4-7 kWh/Sq.m/day in most parts of India
- Energy supply-demand imbalance
- 80% of oil is imported
- High reliance on imported coal
- Peak power deficit of 12.7%
- 50% of India’s population has very little access to electricity
- GHG emissions
- Policy and Regulatory support(MNRE and various state
governments)

8. C-Si dominates in production….
• C-Si Module manufacturing capacity ~ 1500 MW
• C-Si Cell manufacturing capacity ~ 600 MW
• Thin film manufacturing capacity – Negligible
– Moser Baer, Shurjo Energy and HHV Solar
....but, Thin Film dominates in installations

- 60-70% thin films

companies
a-Si/μc-Si CIGS CdTe
Dupont USA MiaSolé USA First Solar USA
ECD/Uni-solar USA Q-Cells(Solibro) Germany Abound Solar USA
Masdar PV Germany SolarFrontier Japan
NexPower China
Schott Solar Germany
Sharp Japan
T-Solar Spain
Note: The above is a partial list of TF companies in India
-CdTe very popular, First Solar has high market share(about 200
MWp)
- a-Si, despite lower efficiencies, has gained acceptance
-CIGS also has takers

4. What could happen?

13. Thin Film Vs c-Si
Advantages Disadvantages
• Temperature coefficient • Conversion efficiencies
• Better performance under • Area requirement
diffuse light conditions • Higher BOS requirement
• Higher Energy Yield • Breakage
• Faster energy payback • Aging behavior not known
• Module grounding not • Materials shortage/toxicity
required for frameless
modules

C-Si(Mono) c-Si(Multi)
- Higher theoretical TF • Better performance under diffuse
energy yield during peak light; lesser shading effect
season • Higher energy yield

15. The result : Higher energy yield for TF
Source: GTM Research
- Theoretically, TF consistently generating more electricity
But..
- First Solar raised the warranty outlay for modules used in
hotter regions
- Anxiety about long term performance of TF is growing

maintains some advantage.

18. Land, BoS and O&M Costs
– Disadvantage for Thin Films
BOS cost comparison : c-Si v CdTe
$13,000 higher for Thin Film plant Source: GTM Research
Land, BOS and O&M high Still …
• Land requirement higher for Thin Films(Leads to more Overall cost lower than c-Si
exposed area – more cleaning, more manpower • Land cost in India is negligible
requirement) • Higher BOS cost offset by lower module
• BoS requirement higher because of lower efficiencies price
(More BOS means more Strings, more cable, more • O&M Labor cost low
Fuses and more breakdown possibilities)
Marketing mantra for TF -$/kWh and not $/Wp

c. Financing
4. What could happen?

20. Cost of Financing
• Local Content Requirement for C-Si, but not for TF.
• Project financing – very challenging to secure
• Indian banks are more comfortable with recourse-to-balance sheet financing
• EXIM, ECB banks offer attractive interest rates
• Even after hedging and insurance, cost of capital at 8-9% as against 13%+ for local
financing
But….
US EXIM financed company – Abound Solar has shut
down production

5. Conclusion

22. Thin films domination to continue, but there
are clouds in the horizon
• JNNSM - Round 2 : 350 MW allotted
– 300 MWp of projects will be in Rajasthan
– At least 250 MW expected to go for thin films
• State solar policies(Gujarat, Karnataka, Rajasthan) – TF likely
to dominate
• But questions about stability of performance at high
temperature set to increase
• Bankability of TF companies(eg. Abound Solar) is
also a concern

5. Conclusion

24. Takeaways..
• Thin film technology adopted by majority of Indian
developers
• Yield, lower capital cost and better financing options
driving TF growth in India
• Local content mandates have had limited impact
• Global TF manufacturers benefitting from India’s
solar boom…
• … but the Indian TF manufacturing ecosystem is yet
to evolve

25. Conclusion – Thin film will win in India, if..
• Bankability questions are properly answered.
– First Solar performance in high temperature conditions
– Abound Solar’s capabilities
• Higher energy yield is proven in the field over a period
of time
• Thin Film remains cost competitive(land cost, capital
cost, O&M cost) relative to c-Si
Bottom line – Technology with best $/kWh will win
