India Enters a New Phase of Solar Expansion with Strong Rooftop and Utility-Scale Momentum

India’s solar energy sector has entered a new phase of expansion in December 2025, marked by simultaneous growth in rooftop installations and utility-scale power projects. This dual momentum reflects increasing confidence among consumers, businesses, and investors in solar as a mainstream energy source.

Rooftop solar momentum across urban and semi-urban India

Residential and small commercial consumers are adopting rooftop solar at a faster pace, driven by rising grid tariffs, improved net metering awareness, and better financing options. Hybrid inverters and battery-ready systems are increasingly preferred for future flexibility.

Utility-scale projects maintain commissioning pace

• New large-scale solar parks connected to interstate transmission networks
• Improved execution timelines by EPC contractors
• Greater use of high-efficiency modules to optimise land usage

Policy stability supports investor confidence

Stable central and state-level renewable energy policies have helped maintain investor confidence. Clear guidelines for grid connectivity, payment security mechanisms, and land acquisition have contributed to smoother project execution.

What this means for India’s energy transition

The parallel growth of distributed and utility-scale solar strengthens grid resilience and diversifies generation sources. It also accelerates India’s progress toward long-term clean energy targets while supporting local employment and manufacturing.
