Harnessing Solar energy, Options for India
A study on harnessing solar energy options for India was conducted recently by Shakti Sustainable Energy Foundation, Climate works Foundation and SSN foundation. Supporting this study it has been concluded that solar energy can play a big role in providing electricity to rural areas and thus has been included in India’s rural electrification policy.

The benchmark cost and subsidy <strong>for</strong> 2010–11 is outlined in Table 19. The capital subsidy <strong>for</strong> special<br />
category states, namely, the North-East, Sikkim, Jammu and Kashmir, Himachal Pradesh and<br />
Uttarakhand, is set at 90%.<br />

3.1.2. Grid-connected <strong>Solar</strong> PV Systems<br />
The JNNSM also supports small-scale grid-connected systems under the Rooftop PV & Small Scale<br />
Power Generation Programme (RPSSGP). The features of this scheme are provided in Table 20.<br />

Notes: *Target <strong>for</strong> Phase 1 of the JNNSM (2010–13).<br />
** Category 2 guidelines will be issued later. Currently guidelines released are applicable to Category 1<br />
only.<br />
The local distribution utility will sign a Power Purchase Agreement (PPA) with the project<br />
proponent, at the tariff determined by the appropriate State Electricity Regulatory Commission<br />
(SERC).<br />
The distribution utility will be paid a GBI <strong>for</strong> the solar power. This shall be equal to the difference<br />
between the tariff determined by the Central Electricity Regulatory Commission (CERC) and the base<br />
rate. The base rate is to be set at `5.50 per kWh <strong>for</strong> the financial year 2010–11, and it shall be<br />
increased by 3% every year.<br />
3.2. Techno-economic Analysis<br />
This section analyses each configuration as categorised and prescribed by the JNNSM guidelines in<br />
terms of its technical and economic merits and limitations. In this study, the LCOE was used to<br />
compare the cost of <strong>energy</strong> generated by rooftop PV (RTPV), a renewable resource, with the cost of a<br />
standard fossil fuel generating unit (diesel generator set). The techno-economic analyses of three<br />
types of rooftop solar systems are considered here:<br />
1. Grid-connected systems<br />
2. Off-grid systems with batteries<br />
3. Off-grid systems without batteries<br />
