Rooftop solar reaches 48 lakh homes — and zero bills for 19 lakh

PM Surya Ghar: Muft Bijli Yojana has installed nearly 40 lakh rooftop solar systems benefiting over 48 lakh households since February 2024, with more than 18.93 lakh consumers reporting zero electricity bills.

What happened

For Prelims

For UPSC: An energy-and-technology item. Use it for distributed/rooftop solar and net metering, India's renewable and non-fossil targets, DISCOM finances and consumer prosumers, and energy access and affordability.
What it is NOT: This is progress on a residential rooftop-solar subsidy scheme — not utility-scale solar capacity, and the zero-bill figure applies to a subset of beneficiaries reported by DISCOMs.

Anchor
The rooftop becomes a power plant — and for 19 lakh homes, the bill goes to zero.
Substantiation (data)
39.72 lakh systems and 48.02 lakh households since February 2024; 6.7 GW added in 2025-26; 18.93 lakh zero-bill consumers.
Exemplification
Net metering turns households into 'prosumers' who consume their own generation and export the surplus.
Problematisation
DISCOM revenue impacts, rooftop access for tenants and small homes, financing and after-sales service constrain scale.
Way-forward
Streamline net metering and DISCOM incentives, expand financing and quality assurance, and converge with PM-KUSUM.
Position
Distributed solar democratises energy generation and is essential alongside utility-scale renewables.
Deploys into: Energy infrastructure + S&T in daily life (GS3.9, GS3.11) · rooftop solar and net metering, the renewable transition, DISCOMs and energy access.
