   It is not just 100GW Solar target, positive macroeconomics beckon investors to India

The target of 100,000MW for solar generation by 2022, announced by the Indian Government, has attracted unprecedented interest from national and international investors. The investors, many of whom are completely new to power sector, were attracted by the long term Power Purchase Agreements (PPAs) and short gestation time for the project besides not having any dependency on fuel linkages. Of course, falling prices of solar cells and competitive bidding have brought the solar power tariffs in India in the range of Rs 5.09 to Rs 5.88 per kWh and quite attractive compared to wind, biomass and even new thermal power projects.

Can India achieve the target of adding 100,000MW by 2022 ?
Can the Hon'ble Minister Piyush Goyal deliver when he says "I want to kill 10 birds with one stone" ?
In the poll conducted after my presentation, majority i.e 48% of the audience thought that Mr Piyush Goyal is likely to do that, with 12% who needed more information and the rest thought it was unlikely. Overall, that's a good sign for Solar India.People say 60GW utility solar may be possible but 40GW of Solar Rooftops may be difficult in India, but we don't have to copy Germany or Japan and rely on rooftops alone. A large part of the agri pumpsets load of 100,000MW, which in rural areas that are far from generating stations, can go partly off grid and partly served through distributed solar generation at feeder level.

   A path breaking approach to sustainable urban and rural transportation!

Our hypothesis that India can target more than 100GW solar easily if solar is used for charging electric vehicles.

Displacing petrol with solar is important as India imports 80% of its oil and uses 50% of the export earnings for oil imports! We should reduce dependency on imported fossil fuels for transportation and decrease the urban air pollution by encouraging the use of solar power for mobility (electric cars, bikes and bicylces).

 We should plan solar charging stations in ‘smart cities’ to begin with, and in rural areas and along the highways in due course.





Assumptions for cost of energy from Rooftop Solar Vs Grid Electricity in Hyderabad

solar vs grid for 100kw hyd 806x393

  1. Grid electricity cost is Rs 9.38 per unit(including fixed demand charges) and escalates at 3% p.a
  2. DG electricity cost is Rs 15 per unit and escalates at 3% p.a and it constitutes 10% of energy mix for next 5 years
  3. Interest cost of 12.5% p.a considered on the diminishing invested amount assuming that savings and REC revenues pay for investment
  4. O&M cost is about 2% and escalates at 3% p.a and Insurance cost is 0.5% of the plant cost on depreciated cost/ WDV
  5. Generation from solar is simulated with PVSyst software using Meteonorm solar radiation datasets for Hyderabad
  6. Solar generation degrades by 0.5% per year.
  7. Renewable Energy Credits (REC) sales revenue is Rs 3.5 per unit until 2017 and Rs 1.5 per unit thereafter for 3 years
  8. Excise / customs duty drawback credit is about 5% of the plant cost
  9. As REC credits have been considered, the project is not eligible for 15% subsidy from central government and hence not accounted.

How do our Grid Connected Solar Rooftop Systems work?


Grid Connected Solar Rooftop Systems are often rooftop based and are integrated into buildings but in India, the major deployment has been in the form of MW scale power projects which took off after the launch of the National Solar Mission in 2010.

solar diagram

  • Electricity in the form of Direct Current (DC) is produced  in the solar cells of the solar panels .
  • The DC electricity from the panels passes through DC network to a grid tied inverter or a hybrid/SMD (Solar – Mains – Diesel) inverter.
  • The Inverter converts the DC electricity into 220V AC for single phase or 415V AC for 3 phase by using state of the art MOSFET or IGBT technology.
  • This is fed to the loads connected to the A/C distribution system linked to the AC grid supply.
  • Solar power will be used as and when it is generated and integrated into the power supply .
    (Optionally the solar power maybe stored in batteries and consumed as and when desired by the client)
  • The metering of the power consumed by the client will through a dedicated automated meter(This will be installed as per the approval of the local distribution company and will comply with CEA standards.)

The design of the system will be finalized during the preparation of the baseline study for the location.
