Progression of Rooftop PV in India
Up to 2004 Up to 2011 Present
3
High capital costs Negligible awareness about PV Did not make economic sense Basic aim of proof of concept Recurrent replacement costs
Availability of subsidy Smaller project sizes; hence low capital Limited decision makers – the owner of system Nil / Low emphasis on optimum output
First two phases …….
4
Large number of stakeholders; and so, decision makers High investments – necessity of convincing financing
institutes Low quality work can mar the project profitability Low knowledge levels – entry of all types of operators
Makes economic sense Revenue guaranteed for many years (in most cases) Can avoid battery; thereby reducing recurrent costs
Present phase
5
PV systems without storage
Roof top installations – high potential all over India
Today’s focus

Projects with long term PPA
• Allocation through reverse bidding
• Fixed tenure – fixed tariff projects
• Limited sanctions from long list of proposals
• Project size between 5 MW and 50 MW
• 8 state-announced policies• Presently about 90% share
of this type
Projects with higher early returns
• Under REC framework• No restrictions on number
or capacity of projects• Spread over many locations
and states where radiation is better
• Revenue through energy sale and green certificates trading (RECs)
PROJECT TYPES - PVROOFTOP GRID INTERACTIVE SYSTEMS

Captive cum grid export system
•Only extra energy exported to the utility grid•Saves on energy usage from utility•No preferential tariff for export or no tariff at all•Prime objective is to support internal grid
Net metered system
•Extra energy exported to the utility grid•Only net metered energy accounted commercially

Two rooftop projects by governments
Gandhinagar Rooftop projectMadhya Pradesh Rooftop
project
One city – 5 MW 4 MW on government
buildings; 1 MW on private Tariff based bidding to
identify developer Investment by developer
and incentive to roof owners Private utility as power
purchaser at the tariff
Three cities – 5 MW Only government buildings Bidding based on tariff and
capital cost Tariff capped at MP state
rate of ground mounted 30% Capital subsidy by
MNRE No incentive / rent to roof
owners State utility as purchaser
9
5 MW in two cities Government buildings Net metering Cap on capacity of all systems in one DTR Cap also due to maximum monthly energy requirement
of each metered customer

Factories like Larson & Toubro, Mercedez Benz, Nalco and so on
Developers like Sukam, Tata Power Solar, etc. Karnataka, Tamil Nadu, Andhra Pradesh, Kerala have
announced rooftop programs DMRC rooftop project on metro station Various municipal corporations across India have
initiated projects Various banks on rural branches
Examples

Tax sops for individual roof owners? Roof identification as an independent business Regulations being framed for net metering – FOR,
DERC, TNERC, other SERCs Railways thinking on large rooftop PV plants Warehousing Corporation Food Corporation of India Rooftop solar power tool being developed by TERI
New Initiatives
Increasing Focus on (grid interactive) Rooftop PV
A Definite future of solar in India
Attracting public participation
Just the beginning – policy, regulatory, utility and public awareness, financial backing, technology at component level
Net metering and reduced cost of solar power –most influential factors deciding future of rooftop in India
