“Upfront Capital Investment Problem for Rooftop Solar Popularization, Even in Delhi”, Energy News, ET EnergyWorld

New Delhi: Even for a wealthy city-state like Delhi, the initial capital investment required for a rooftop solar system (RTS) remains a barrier for a large portion of residential consumers, according to a latest study.

Affordable and accessible financing options are needed to convert consumer interest into on-the-ground installations, according to the study implemented by the Council on Energy, Environment and Water (CEEW) and others in two urban areas of Delhi.

With a technical potential of 210 GW in urban areas, Residential Rooftop Solar (RTS) is critically important to achieving India’s ambitious target of 500 GW of non-fossil fuel capacity by 2030. The RTS also presents economic and environmental savings for consumers and electricity distribution companies. (discom).

However, RTS deployment in general remained poor – 6.4 GW of installed capacity against a total solar installed capacity of 49.34 GW. In fact, a recent report earlier in the month pointed out that India is set to miss the 2022 solar target by 27% as it is expected to fall well short of its 2022 target of having 100 GW of installed solar capacity. , largely due to slow adoption of rooftop solar.

In an effort to accelerate the adoption of residential RTS in India, the US-India Clean Energy Finance Task Force, co-led by the US Department of New and Renewable Energy (MNRE), piloted the Solarise Delhi campaigns which involved interactions with the community, in person and virtually in light of the pandemic. The campaigns successfully reached 1,400 consumers over three months and generated interest in 140 kW of RTS installations.

The findings and recommendations of the study report by Akash Som Gupta, Bhawna Tyagi, Neeraj Kuldeep and Selna Saji, “Unlocking Demand for Residential Rooftop Solar in India: Learnings from Solarise Delhi Campaigns”, suggest that by aggregating information into one place, by providing compelling offers and leveraging community trust, the Solarise pilot campaigns very effectively initiated conversations and sparked consumer interest in RTS in an innovative way.

The study also highlighted that with engaged stakeholders and a supportive ecosystem including funding options, Solarise campaigns (and campaigns of a similar nature) can become a powerful tool for increasing RTS adoption in the industry. residential.

The Solarise campaigns were also effective in raising consumer awareness of RTS, with 43% of participants saying the campaigns helped increase their level of awareness.

Alongside the two power discoms, BSES Rajdhani Power Ltd (BRPL) and BSES Yamuna Power Ltd (BYPL), the Solarise campaign pilots were implemented by collaborating partners of the task force – the Energy Council, Environment and Water (CEEW), SmartPower Inc. and WeeGreen Inc – as well as local nightclubs and Resident Welfare Associations (RWA) to increase RTS adoption at the household level.
