Abstract: This work is to highlight the potential of Delhi, to contribute towards Jawaharlal Nehru National Solar Mission (JNNSM). Essentially a case has been drawn based on few assumptions, to find out the how viable it is to invest in solar rooftop under residential segment in Delhi. The rooftop space potential has realized, supporting policy framework has been marked which will give encouragement to a residential consumer to put a step forward towards self-consumption by solar PV rooftop. The subsidy of central finance assistance (30%) will play a vital role to switch electricity consumption from conventional to renewable. Self-Owned Rooftop Solar Systems is supported to a group of residents together by Virtual- Net metering concept (Draft Delhi solar policy). Delhi’s residential segment holds the maximum potential for “Solar PV Rooftop’ by roof space. The analysis shows that the realizable technical potential of the solar is 128 GW, which is much sharper than 40 GW; therefore is not expected a stone in a way for achieving a governments target. In the trend of increasing electricity tariff rates and increasing electricity consumption, there is certainly a need for Individual residents to think a step ahead and contribute Nation’s solar mission and sustainability, while becoming independent producer of electricity, aiming self-consumption and optimization of solar energy. As per Study done by “Bridge to India – India Solar Handbook 2016 Map†the total Installed Capacity of Residential Solar PV Rooftop until March 31, 2016 is about 6 MW in Delhi. And, it has a long way to go.
Moreover, Challenges are not less but benefits are huge in long run. The basic idea is that this study is being targeted to the residential segment consumers belonging to above ‘High Income Group’, particularly looking to invest in power backup solution. So, question is how economically viable it is to replace Diesel Generator with a solar PV rooftop on resident. The answer to this lies in the consumer’s perception to adapt.
Key words: Economic viability, Solar PV rooftop, Residential segment, Delhi, Net metering.
