India has 1 crore homes ready for rooftop solar. Only 22.7% of interested households ever get installed. Sondia closes that gap — an end-to-end AI layer that guides every homeowner from first question to switched-on, and gives every installer the tools to deliver at scale.
The wedge
Panels are cheap. Subsidy is real. Demand is overwhelming. And yet — between the Google search and the first kWh, Indian households disappear. Fragmented quotes, opaque subsidy paperwork, nervous EMI conversations, installer no-shows. The conversion wedge isn't hardware. It's the operating system around it.
See the 10 layersEvery Indian rooftop owner knows solar pays back. Google searches and enquiries have never been higher.
Only 22.7% of serious enquiries become installed systems. The other 77.3% are lost between sizing, subsidy, financing and trust.
Small and mid-size installers carry the country — but run on WhatsApp, Excel and goodwill. No operating layer. Sondia is that layer.
The operating system
Sondia is not a lead-gen site, not a marketplace, not an EPC. It's the AI layer that runs underneath all of them — so homeowners feel guided, and installers feel armed.
AI concierge answers solar questions in plain Tamil, Hindi and English.
60-second sizing from bill, roof and state — with subsidy and payback built in.
AI-assisted layout for shading, tilt and aesthetics — not a template.
EMI, CAPEX and zero-down options modelled in real cashflow terms.
Routed to a vetted local installer on the Sondia network — not an auction.
PM Surya Ghar & state paperwork handled end-to-end. No chasing DISCOMs.
Installer portal runs the job — site visit, BOM, crew, safety, sign-off.
Net-meter approval, inverter config and app setup on day-one.
Generation, alerts and cleaning cadence in a single home dashboard.
Referral, EV charger, battery, community solar — next ray, same OS.
