Rooftop Solar PV Developments in Indian States

Posted · Add Comment

Some of the state governments has already initiated their rooftop solar PV programs and introduced feed in tariffs to attract the investments in rooftop solar PV projects.


In Gujarat government initiated a  5MW Rooftop Project in Gandhi Nagar in PPP model. In this scheme the generated power from the rooftop solar is completely fed to the grid. The rooftop owner gets paid lease rent (Rs.3.00 per unit) and the project developer gets feed-in-tariff (Rs.11.21) for 25 years. Looking at the success of this project the government has recently scaled up this  rooftop scheme for development of 25 MW in 5 other cities.


Similarly Kerala  launched  its  10,000  rooftop  power plants program for 2012-2013. In this scheme each  applicant  eligible  to  apply  for  1 kW only, and 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 Bangal

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. The Policy  targets  16  MW  of  rooftop  and  small  PV installations by 2017.



Tamilnadu introduced its solar policy inn 2012 with a targets  3000  MW  solar power by 2015. This target include the  350  MW  of  rooftop solar PV installations. The proposed capacity of rooftop SPV capacity  will be implemented in   three  phases  of  100,  125  and  125  MW  (per year) during 2013-2015.  In this government of Tamilnadu will also target the domestic consumers for 50 MW rooftop capacity. The domestic  customers   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. The government also targets 300  MW  from  government  buildings  and  government schemes for rural and urban lighting.. In order to promote the solar PV in its industrial and commercial consumers, the government has mandated 6% SPO for HT consumers to achieve targets.. TEDA is designated single window agency for implementing solar projects. The connectivity to rooftop systems shall be at  240 V for rooftop systems up to 10 kW capacity. However the connectivity will be provided at 415V  fir rooftop systems up to 100 KW capacity.

Andhra Pradesh

AP  Solar  Policy  2012  is also  promoting  roof  top  solar projects. Presently the scheme is launched for 3 phase service  consumers  and net metering guidelines have been issued. The surplus exported power will be bought by the Discom at a rate of  Rs.3.50 per  unit for  7 years.


Rooftop Schemes through MNRE/SECI

MNRE  has recently a  pilot  scheme  for  grid  connected  rooftop  PV  power projects. The scheme allows  system size  from 100 kW to 500 kW .  Aggregation of capacity from smaller roofs is allowed.  Systems are to be grid connected without battery back up.  Solar power would be exported to grid, whenever in excess of the  consumption of the building. SECI will implement the scheme through competitive bidding on the project cost. The selected bidders in each city will implement the projects.  30% of the cost would be provided as subsidy and 70% to be met by the  consumer.

Phase-I of this scheme is already started with the following allocations:

  • Chennai     – 2 MW
  • Bangalore     – 2 MW
  • Delhi       – 1 MW
  • Gurgaon     – 0.5 MW

Phase-II: Bids invited for a capacity of 11.1 MW:

  • Jaipur       – 3.1 MW
  • Bhubaneswar/Cuttack    – 1 MW
  • Hyderabad     – 2 MW
  • Gurgaon     – 1.5 MW
  • NOIDA/ Gr . NOIDA   – 1.5 MW
  • Raipur       – 2 MW
