SECI Rooftop Activities Ongoing
Grid connected Rooftop Scheme ndash (Phase I to IV) PAN India
80 MWp
73 MW Rooftop scheme for Warehouses
50 MWp Rooftop Scheme for CPWD in RESCO mode
250 MWp Rooftop Scheme under 30 Subsidy ndash PAN India

SECIrsquos Grid Connected Rooftop Scheme
This ldquofirst-of-its kindrdquo scheme was launched in Jan 2013
Target Group Educational Institutes Hospitals Government bodiesPSUs Commercial Establishments Industries Warehouses Residential Sector etc
Grid connected systems without battery back up surplus solar power if any could be fed to the grid (under net-metering)
MNRE provides Central Financial Assistance (CFA) through SECI
30 subsidy is available for schoolscolleges residential sector Social sector etc
CFA is not available to commercial and industrial sector
Implementation Model
Projects are implemented under two broad
business models

cost
II RESCO (PPA Model) ndash bids invited on tariff
Against total 1225 MWp rooftop capacity
allocated
70 MWp under Capex Model
525 MWp under RESCO
Achievements so farhellip
Rooftop programme expanded from Tier I
to Tier III cities covering 20 StatesUTs over 60 cities
Benchmark cost reduced from Rs 130Wp to Rs 80Wp
80 MWp capacity allocated among 40 successful bidders covering 20 States including Andaman amp Nicobar Islands of India
More than 515 MWp (lt 200 nos projects) rooftop capacity sanctioned so far
40 MWp commissioned
Rs 44 Cr CFA released to the project developers (inter-alia means more than Rs 220 Cr
investment in the rooftop segment)
Price trend of Rooftop projects
bull Open Competitive bidding process have resulted in lowering of Benchmark cost from Rs 130Wp
to Rs 80Wp
bull Discovered project costs through competition are even lower than the benchmark cost

bull Proper levelling and alignment
bull Proper space in between arrays to avoid shadows
Quality Implementation Issues - 2
bull Quality of Solar Modules
bull In spite of IEC certification field level failures
of modules being reported
bull Various visual defects like

SECI Rooftop Activities Ongoing
Grid connected Rooftop Scheme ndash (Phase I to IV) PAN India
80 MWp
73 MW Rooftop scheme for Warehouses
50 MWp Rooftop Scheme for CPWD in RESCO mode
250 MWp Rooftop Scheme under 30 Subsidy ndash PAN India
500 MWp Rooftop Scheme without Subsidy
SECIrsquos Grid Connected Rooftop Scheme
This ldquofirst-of-its kindrdquo scheme was launched in Jan 2013
Target Group Educational Institutes Hospitals Government bodiesPSUs Commercial Establishments Industries Warehouses Residential Sector etc
Grid connected systems without battery back up surplus solar power if any could be fed to the grid (under net-metering)
MNRE provides Central Financial Assistance (CFA) through SECI
30 subsidy is available for schoolscolleges residential sector Social sector etc
CFA is not available to commercial and industrial sector
Implementation Model
Projects are implemented under two broad
business models
I CAPEX (Ownership Model) ndash bids invited on project
cost
II RESCO (PPA Model) ndash bids invited on tariff
Against total 1225 MWp rooftop capacity
allocated
70 MWp under Capex Model
525 MWp under RESCO
Achievements so farhellip
Rooftop programme expanded from Tier I
to Tier III cities covering 20 StatesUTs over 60 cities
Benchmark cost reduced from Rs 130Wp to Rs 80Wp
80 MWp capacity allocated among 40 successful bidders covering 20 States including Andaman amp Nicobar Islands of India
More than 515 MWp (lt 200 nos projects) rooftop capacity sanctioned so far
40 MWp commissioned
Rs 44 Cr CFA released to the project developers (inter-alia means more than Rs 220 Cr
investment in the rooftop segment)
Price trend of Rooftop projects
bull Open Competitive bidding process have resulted in lowering of Benchmark cost from Rs 130Wp
to Rs 80Wp
bull Discovered project costs through competition are even lower than the benchmark cost

Achievements so farhellip
Rooftop programme expanded from Tier I
to Tier III cities covering 20 StatesUTs over 60 cities
Benchmark cost reduced from Rs 130Wp to Rs 80Wp
80 MWp capacity allocated among 40 successful bidders covering 20 States including Andaman amp Nicobar Islands of India
More than 515 MWp (lt 200 nos projects) rooftop capacity sanctioned so far
40 MWp commissioned
Rs 44 Cr CFA released to the project developers (inter-alia means more than Rs 220 Cr
investment in the rooftop segment)
Price trend of Rooftop projects
bull Open Competitive bidding process have resulted in lowering of Benchmark cost from Rs 130Wp
to Rs 80Wp
bull Discovered project costs through competition are even lower than the benchmark cost

bull Lack of proper assessment at sites
bull Need to link with data from Solar Radiation Resource Assessment Stations and Solar
Resource Mapping
bull Proper shadow analysis
bull Mounting Structures
bull Galvanizing thickness depending on local Environmental conditions ndash corrosive etc
bull Good quality high strength structures with annealed fasteners
bull Structures to be adequately designed to with stand wind pressure as per different wind
zones in India
bull Cabling laid along the structure to use proper synthetic rubbers having life of 25 years
bull Proper levelling and alignment
bull Proper space in between arrays to avoid shadows
Quality Implementation Issues - 2
bull Quality of Solar Modules
bull In spite of IEC certification field level failures
of modules being reported
bull Various visual defects like
bull Encapsulation discoloration amp delamination
bull Diodes and Solder bonding failure
bull Back sheet delamination
bull Hair cracks on glasses Micro cracks on cells
bull Hot spots ribbon heating
bull Performance defects like
bull Potential Induce Degradation (PID)
bull Light Induced degradation
Degradation of PV modules in
various climatic zones in India (
Source NCPRE)
Effect of PID on power generation
( Source PV-tech)
Quality Implementation Issues - 3
bull Inverter Failures bull Failure due to heating
bull Improper ventilation
bull Failure of electronic components
bull Frequent IGBT failures
bull Capacitor failures
bull Damages due to surges
bull Earth faults
bull Performance related bull Power quality issues
Ways to address Quality Issues - 1
bull Extended IEC tests are required to suit Indian
conditions based on Field experiences
bull High temperature and high Humidity
bull Sand storms
bull Hail storms
bull Corrosive atmosphere
bull Use of proper Bill of Materials (BoM)
bull Rigorous Pre-dispatch checks
bull RFID tagging
bull Regular IR thermograph studies under operation to
remove faulty modules
bull Electro Luminous camera assisted manufacturing to
avoid various physical defects
Aerial view of IR imaging of
solar plant
Ways to address Quality Issues - 2
bull Adhere to the various standards
bull Rigorous accelerated test procedures
bull Controlled Electrical Parameters as per site conditions
ChallengesIssues in Rooftop PV - 1
Three Significant Classes of Concern
Technical Grid integration challenge with likelihood of
bull Reversal of power flows across the LT network
bull Breach of voltage regulations with tail end generation feed
bull Grid Availability Erratic behavior of LV protection systems
bull Commercial Utility likely to have
bull Loss of consumers reduction in revenue in net metering captive operation
PolicyFinancing concern
bull Lack of consistent policyregulation in terms of bull filing of application net metering grid-interconnection and energy
accounting
bull Variance in net-metering policies
bull Few states with gross-metering policy
bull NOC from DISCOM
bull No model tendering procedure
bull Maximum Cap (1MW) for Net metering project in some states
bull Need for simple and low interest rate financing
bull Lack of awareness among consumers
bull No clarity Open Access charges CSS wheeling charge banking etc
