2. ABOUT SHRI SHAKTI ALTERNATIVE
ENERGY LIMITED, HYDERABAD
0 Developing the 100MW
Rajasthan Solar Processing
Zone
0 Judged as one of the most
promising clean energy
investment opportunities
in Asia.
0 Completed several
consultancy projects for
the World Bank, ADB, KWF,
UNIDO, UNICEF

3. ROOFTOP PV SYSTEM
0 Installed on rooftops of residential or commercial
buildings
0 Can cope up with substantial growth in peak
electricity demand
0 Can be with or without grid interaction.
0 Create economic value for unutilized rooftops and are
not faced with the issues of land availability

4. OBJECTIVE OF INSTALLING
ROOFTOP SOLAR PV SYSTEM
0On national level, reduces requirement of land for
addition of solar capacities.
0It reduces the dependency of the consumer on grid
power and mitigates the dependency on diesel
generator.
0To provide access to electricity to all rural
households especially where grid connectivity is
not a cost effective solution. .

5. COMPONENTS REQUIRED FOR
ROOF TOP SOLAR PV SYSTEM
0 Solar PV Modules

8. 40kWp Grid Interactive Rooftop
PV Power Plant at IHM,
Shri Shakti, Hyderabad
0 FEATURES OF THE PLANT
0 40kWp Grid Connected System
0 Located at Begumpet,
Hyderabad
0 800 sq. m. available vacant
rooftop area
0 Implementation in 2 parts:
18kWp(fixed) and 22kWp(with
tracking)
0 Annual Energy Generation:
70MWh

9. LOCATION
0 Adjacent to Hotel Fortune Select Manohar, Begumpet,
Hyderabad
0 Old Rajiv Gandhi Airport in the North
0 Metrological Observatory, Hyderabad in North East

10. SITE
DESCRIPTION
• Rooftop has a skylight system
with dome like structures for
natural lighting.
• The skylight has an area of
around 330 sq meters .
• Could be used for SPV
installation of 18kWp without
affecting the natural lighting
• Rest of the terrace has around
475 sq meters of vacant area
which could be used for SPV
installation of 22kWp.

11. TOOLS/INSTRUMENTS USED
FOR ANALYSIS OF SPV SYSTEM
0 SEAWARD PV 150
SOLARLINK KIT
0 SOLMETRIC SUNEYE 210
SHADE TOOL

12. 0 PVSYST Simulation
Software
0 TRACKING SYSTEM
WITH PV BOOSTER
MIRRORS

13. ARRANGEMENT
18kWp System:

14. 22kWp System:

15. INTEGRATION OF PV POWER
WITH GRID
0 The output power from SPV would be fed to the
inverter
0 In case of grid failure, or low or high voltage, solar PV
system shall be out of synchronization and shall be
disconnected from the grid.
0 The out put power from inverter would be fed to the
panel of 320 KVA DG set with changeover switch at
IHM
0 On the week end and other holidays, almost the entire
energy from the SPV module would be fed into the
grid.

16. METERING SCHEME
0 An Import/Export meter will
be installed for metering for
billing purpose
0 Would also serve the purpose
of registering the net export
and import to the grid.
0 A meter would also be installed
at the output side of the
inverter to register the energy
output from the SPV power
plant.

17. IMPLEMENTATION OF WORK
0 Plant in primary stage
0 Equipments have been procured
0 Full Implementation yet to be done
