The Levellised Cost of Generation for rooftop PV and other small solar

power projects, in accordance with the assumptions outlined above work out

to Rs 19.57 /kWh.

Applicable Tariff (Proposed):

Accordingly, it is proposed that Tariff for Small Solar Systems (< 1 MW)

may be determined as Rs 19.57/kWh to be valid for period of 25 years

from the date of commissioning provided that such small solar projects (<1

MW) are commissioned on or prior to March 31, 2012 in case of small solar

PV and on or prior to March 31, 2013 in case of small solar thermal power

projects.
