The document discusses off-grid rooftop PV as an alternative to India's unreliable central grid. It notes India's growing power deficits and shortfalls in capacity additions. Off-grid rooftop PV is presented as a solution that reduces reliance on the grid, transmission losses, and pollution from diesel generators. Key advantages of off-grid over grid-tied systems are also summarized. The document promotes off-grid rooftop PV for non-electrified villages and concludes that rooftop PV growth is inevitable given India's worsening power crisis.

UNLEASH THE
UNLIMITED POWER

9. Why Ro o fto p PV?
Reduced reliance on the grid
Offsetting the usage of diesel generators, leading to
lower pollution
Max power generation at max load(for commercial
segment)
Consumption at the point of generation
Significantly reduced transmission losses.
The Aggregated Technical and Commercial (ATC) losses in India are
expected to be about 32%.
1 kWh of power lost for every 3 kWh generated, which means 2 kWh
of power from rooftop = 3 kWh of kWh from far-off thermal plant
Operation and Maintenance – Easy and inexpensive

10. Off - grid o r grid - tied PV?
Parameters Off-grid Grid-tied
Grid
connection
Operates independent of the
utility power grid
Connected to the utility power grid
Suitability
Suitable when utility power is not
easily accessible or cannot be
installed
Used when selling power to utility or
the system smaller than the
minimum power load.
Storage
required
Yes No
Cost Costlier– due to battery bank Less expensive
Installation Easy to commission
Complex – restricted by the utility
grid
Monitoring Important, but not critical
Requires grid related monitoring,
feedback and safety features

11. Why o ff - grid PV?
No uncertainty about Feed-in-Tariff
No off-taker risk(PPA risk) – losses of utilities
at 88,170 Crores
No need for net-metering
System not dependent on the uptime of the
grid
Does not lead to destabilisation of the grid
I deal for non-electrified villages

12. Techno lo gy Fea sibility
PV system for rooftop – well proven.
Grid-interactivity – could be a problem, but not for off-grid projects.
Mounting of PV dependent on load bearing capacity of roof and structural
stability .

13. Summa r y
Power crisis set to worsen
Rooftop PV potential is huge
Key to growth – Innovative business models
-Rooftop PV growth – inevitable
