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
