Benefits
Ø Significant
cost savings in avoiding to lay down
electrical wires, distribution points, employing labor and doing away with
digging hassles
Ø High durability of solar
panels and LEDs. Both solar panels and LEDs last for more than 10 years. In
comparison, the conventional sodium and CFL lamps typically require replacement
at least once every year
Ø Close to a
month’s time saved in newly constructed places as a result of easy
installation (feedback from builders)
Ø Zero electricity cost
Ø 80% depreciation benefits
Ø Environment friendly and easy
disposal due to absence of harmful substances like mercury and lead
Ø Less heat
dissipation
Ø Higher color
temperature of light (purer form of light)
Ø Carbon Credits
and subsidies may be availed for large installations
Ø Cleaner and Greener environment to breathe!
