Solar Lighting in India
Why Solar?
India has 300 clear days of sunshine
Established technology globally
Power generated at the point of consumption
No cabling costs / Transformer
Negligible maintenance
Why off-grid solutions?
40% of population has little or no energy access
Peak energy shortage of 12% in 2009-10
Reference
Diesel generators of 20% of grid installed capacity already running – Reduce
Carbon Footprint
Problems in Current Solar Lighting Market
Very low understanding of LED Technology
CFL continues to dominate – low lumen efficacy
Local players designing poor quality solutions
High failure of solar solutions
Over design or under design
Highly inefficient system – consumes more power
Lack of standardsLack of standards
