India’s Solar Surge 2025: What the 125 GW Manufacturing Boom & Rooftop Growth Mean for Vendors & Homeowners

India is seeing a rapid acceleration in solar manufacturing and rooftop installations. With domestic module capacity scaling toward 125 GW by 2025 and rooftop additions surging year-on-year, the market dynamics are shifting in favour of faster deployment, lower lead times, and more competitive vendor offerings. Below is what vendors, homeowners and businesses need to know — and how SolSetu helps bridge demand to trusted vendors.

Snapshot: Why 2025 matters

Key facts (October 2025):

• Domestic manufacturing expansion: Module manufacturing capacity is scaling rapidly toward ~125 GW, improving domestic supply resilience.
• Rooftop boom: Rooftop installations rose sharply in 2025 (residential & commercial), with a multi-state surge in deployments.
• Grid shift: Solar's contribution to generation is increasing while fossil fuel generation share is reducing — making solar a mainstream generation source.

What this means for vendors

What homeowners & businesses should watch

• Look for vendors who list installation timelines, module origin (domestic vs imported), and finance/subsidy assistance on their profiles.
• Compare quotes that include warranty & commissioning timelines — faster domestic module supply can shorten project timelines.
• Check eligibility for state or national schemes (examples: rooftop subsidies, PM-KUSUM components, and local net-metering rules).
