## Questions owners ask

**Where do these numbers come from?** From you. Count last month: leads from every source, how many you actually spoke to, how many booked a survey, and how many signed. We use no industry averages, because there is no reliable published one for Indian rooftop solar.

**Why focus on leads reached?** A lead you never speak to cannot be surveyed or signed, however good your price. It is also the step most installers can change fastest: call back in minutes, try again at different hours, and message on WhatsApp.

**Does it promise subsidy amounts?** No. Subsidy amounts and eligibility change. Point customers to the official PM Surya Ghar portal for current figures.

**Can these calls be automated?** Yes. An AI sales employee calls every enquiry within a minute, asks for the bill, load and roof details, keeps trying when nobody answers, and books the survey for your team. Prices are on our pricing page.
