Why Rooftop PV
• On national level, reduces requirement of
land for addition of solar capacities
• For consumers, it
– Reduces the dependency on grid power
– Mitigates diesel generator dependency
– Long term reliable power source
• For Discoms, it reduces
– Day Peak load Demand
– T&D and conversion losses as power is consumed
at the point of generation
• Most suitable for commercial establishments
– Max generation during peak usage time
– Solar power cost is close to the commercial power
cost
Roof top PV potential in India
• According to 2011 Census India has:
– 330 million houses
– 166 million electrified houses
– 76 million houses use kerosene for lighting
– 1.08 million houses use solar for lighting
– 140 million houses with proper roof (Concrete or
Asbestos / metal sheet)
– 130 million houses having > 2 rooms
•
Average houses can accommodate 1-3 kWp of
solar PV system
•
Large commercial roofs can accommodate
larger capacities
•
As a conservative estimate, about 25 GW
capacity can be accommodated on roofs of
buildings having > 2 rooms alone (considering
20% roofs are available/suitable)
Rooftop PV Programmes under
JNNSM
• Small scale rooftop PV systems
–
Size: less than 100 kWp
– Implemented through MNRE Channel
Partners
– Generally in off grid mode
•Large scale rooftop PV scheme
– Size: 100 to 500 kWp grid-connected systems (without battery back up)
– Implemented through SECI through a process of competitive bidding
– 3 Phases announced; Phase I: 5.5 MW (4 cities); Phase II: 11.3 MW (6 cities);
Phase III: 10 MW (9 cities)… more to come
– Possible locations include public buildings, hospitals, educational institutions,
warehouses etc.

SECI’s Implementation methodology
• SECI is implementing the scheme by selected developers through
competitive bidding on the project cost in for selected cities .
• SECI has prepared technical specifications to ensure quality of
installations.
• Under the scheme SECI will
– Allocate capacity to selected bidders for each city.
– Verify project proposals w.r.t. technical specifications and release
the sanction for subsidy which is linked to performance up to 2
years.
– Release initial subsidy on successful commissions as per technical
specifications. (20%).
– Release 5 % subsidy at the end of 1st and 2nd year of successful
maintenance of the project.
– Help developers for identification of projects through dissemination
workshops and to assist in resolving any issues with concerned
authorities.
Status of Implementation
Phase-I:
•
•
•
 Chennai – 2 MW
 Bangalore – 2 MW
 Delhi – 1 MW
 Gurgaon – 0.5 MW
Companies shortlisted as per their
bids for each cities against
benchmark project cost of Rs.
130/Wp
Projects allocated up to ~ Rs. 88/Wp
About 4.5 MW of projects already
identified
and
started
implementation
Phase –II:
Revised benchmark cost Rs. 90/Wp
 Jaipur – 3.1 MW
 Bhubaneswar/Cuttack - 1 MW
 Hyderabad – 2 MW
 Gurgaon – 1.5 MW
 NOIDA/ Gr. NOIDA – 1.5 MW
 Raipur – 2 MW
 The initial deadline for identification of
the Projects is 14th Nov, 2013
Experience in Bhubaneswar
• 1 MW allotted to two bidders under Phase II of Rooftop scheme
• Following developers selected:
– M&B Switchgears Ltd (500 kW)
– Photon Energy (500 kW)
• About 700 kWp of projects have already been identified
– Kalinga Institute of Social Sciences (500 kW)
– NALCO (160 kW +) - Requested for more capacities on their Angul Plant.
• Orissa government is also implementing/planning to install roof-top
projects on government buildings
• More roof-top capacities could be considered for allocation, if there is
good progress and interest of the stake holders
Main Issues in implementation
Connectivity Issues
 Electricity to be fed into grid at Voltage level below 33 KV
 No clarity on connectivity norms at these voltages
– However, CEA has published the CEA (Technical Standards for
Connectivity of Distributed Generated Resources), Regulations 2013
recently to address these issues
Metering issues
 Many states have no regulations on net metering
 No uniformity of standards, different state regulations inconsistent
– CEA has come up with draft CEA (Installation and Operation of
Meters) Amendment Regulations, 2013
– SECI working with states to bring out net metering regulations
Contd…
Business models – Tariff & PPA etc
 Confusion over contract clauses; different tariffs quoted to different
consumers
‫ ـ‬SECI has identified some key provisions to be a part of PPA for
benefit of rooftop owners and developers
‫ ـ‬SECI may assist in discovering optimum tariff structure
Project Performance
 Performance of large scale grid connected rooftops untested in India
- SECI to monitor performance and facilitate mitigation of issues
(if any)

States’ Initiatives for Rooftop PV
Initiatives for promotion of Rooftop PV
in Andhra Pradesh
 AP Solar Policy 2012 promoting roof top solar projects
 Only for 3 phase service consumers can setup roof top PV systems
 Net metering is allowed
 Recently announced by a committee that Rs.3.50 per unit would be
paid for exported power for 7 years
 The consumer/SPV generator also
has to set up a protection system on
their premises with “Islanding” for
events like grid failures
 Any
prevalent
subsidy
from
Government of India can be availed.
Gujarat
 Gujarat already initiated 5MW
Rooftop Project in Gandhi Nagar in
PPP model.
 Generated power is completely fed to
the grid.
 As per their model, Roof owner gets
paid lease rent (Rs.3.00 per unit) and
the project developer gets feed-intariff (Rs.11.21) for 25 years.
 Recently announced a rooftop
scheme for development of 25 MW in
5 other cities.
Kerala
•
Kerala launched its 10,000 rooftop power plants
program for 2012-2013.
•
With each applicant eligible to apply for
1 kW
only, the total capacity target is 10 MW.
•
Due to the small per capita limit; the target
audience will be only households and small
cottage industries.
•
Apart from the MNRE’s 30% capital subsidy, the
state is offering a discount of Rs. 39,000 per
system.
•
West Bengal
West Bengal has initiated a net-metering solar rooftop
model promoting self consumption.
•
Under the WBERC Regulations, grid-integrated rooftop
PV is allowed only for institutional consumers like
government departments, academic institutions, etc.
•
The system size limited to 2-100 kW, Connectivity is
allowed at Low Voltage or Medium Voltage, or 6 KV or
11 KV, of the distribution system of the licensee.
•
Solar injection is permitted only up-to 90% of the
annual electricity consumption, and the net energy
supplied by the utility would be billed as per existing
slab tariffs.
•
Solar generation would first offset consumption in the
highest tariff slab and then the lower slab.
•
Policy targets 16 MW of rooftop and small PV
Kolkata development
authority mandated all
commercial and high raise
building to install solar PV
to meet 2% of their energy
demand.
Tamil Nadu Solar Policy 2012
• Targets 3000 MW by 2015 , including 350 MW of
rooftop capacity in three phases of 100, 125 and
125 MW (per year) during 2013-2015.
• 50 MW from domestic customers who will receive
a GBI of Rs. 2/kWh for the first two years, Rs.
1/kWh for the next two and Rs. 0.5/kWh for the
subsequent two years.
• 300
MW
from
government
buildings
and
government schemes for rural and urban lighting.
• Mandates 6% SPO for HT consumers to achieve • Connectivity :
targets.
• TEDA designated as single window agency.
< 10 kW - 240 V
< 100 kW – 415 V
> 100 kW - 11 kV
Uttarakhand
• Uttarakhand Electricity Regulatory Commission released regulations for solar
roof top plants.
• Allowed roof to projects to connect at the following voltage levels
(i) Load up to 4 kW: low voltage single phase supply
(ii) Load >4 kW and up to 75 kW: low voltage three phase supply
(iii)Load >75 kW and up to 1.5 MW: at 11 kV
(iv)Load >1.5 MW and up to 3 MW: at 11/33 kV or as per site condition.
• UERC determined levelized net tariff for roof top systems as Rs.9.2 without
accelerated depreciation and Rs. 8.15 and with accelerated depreciation.
Other States/UT
