The Cabinet Committee on Economic Affairs (CCEA) approved a total funding of Rs 11,814 crore for Phase II of the grid-connected rooftop solar programme on February 19, 2019. The total solar rooftop installation target is 40 gigawatts (GW) by 2022. As of December 2018, the installed capacity was 1.4 GW.
Originally, the scheme for Phase II was proposed and drafted in December 2017, under Sustainable Rooftop Implementation for Solar Transfiguration of India (SRISTI).
In response to the tepid growth under the pre-exsiting subsidy incentives, SRISTI addressed some roadblocks, specifically the reluctance of distribution companies (DISCOMs) considering solar rooftop (SRT) potentially took away high-paying customers — a situation that further entrenches DISCOMs in their financial woes.
Additionally, it also sought to sweeten the deal for the residential segment where the uptake continues to be underwhelming.
The final approved plan — Phase II (SRISTI finds no mention as of now) — appears to have restructured the offerings in SRISTI. For one, at Rs 11,814 crore, it sanctions half the original proposed amount of Rs 23,450 crore. Second, Phase II effectively covers 22 GW as opposed to the total 40 GW under SRISTI.

The Phase II scheme’s increased incentives for smaller residential rooftop systems is a welcome move. Stand-alone houses, which can build SRT only under the capital expenditure model at the moment, are likely to incentivise wary houseowners who have to invest their equity or obtain a loan to finance the system.
The 40 per cent relief on the system cost is likely to encourage more home owners to make the transition.
While the DISCOM incentives have been scaled down, it was unclear from the get-go whether even the SRISTI proposal would galvanise DISCOMs to be more enthusiastic participants in enabling SRT.
A real SRT revolution will need to have DISCOMs reap real revenues and advantages, not mere subsidies. It remains to be seen how the DISCOMs view the scheme and respond to it in terms of effective implementation.
