Executive summary
AI answer engines now help Indian homeowners and small businesses decide whether rooftop solar pays, how to claim the subsidy, which installer to trust and how net metering works. We ran 25 questions across five categories with live web search. The run produced 375 citations from 121 unique domains.
SolarSquare leads on 66.4 percent and ranks first on 13 of 25 questions. Heaven Green Energy follows on 37.6 and Freyr Energy on 35.2, while Bridgeway Power and QuickEstimate tie on 20.8. Tata Power Solar, the leader in Mercom's 2025 installer ranking, is sixth on 14.4.
The sharper finding sits in the sources. Installers write the answers, and one Surat group, Heaven Green Energy with its software and inverter sister firms, supplies 57 of 375 citations. The official PM Surya Ghar portal is never cited, and Indian government sites supply only 10.

Visibility score method: each question ranks five entities. Rank one earns 1.00 point, rank two 0.80, down to 0.20 for rank five. Scores are totaled across 25 questions and divided by 25. Every entity named is ranked, whatever its type.
Type shows what kind of organization each entity is. AI engines name lenders, software makers, meter and cable makers, US solar firms and government offices alongside installers and panel makers. All of them are ranked here, because all of them take up space in the answer.

Categories and why we chose them
We chose five categories that follow a homeowner or small business from first idea to a working system: what it costs and saves, which subsidies and loans apply, how to choose an installer, how net metering and approvals work, and what living with solar involves.
| # | Category name | Reason for selection |
|---|---|---|
| 1 | Cost and savings | Cost is the first question every buyer asks: what a system costs, how much it cuts the power bill, how long it takes to pay back, what size to buy and whether it suits a shop or factory. These answers decide whether anyone buys at all. |
| 2 | Subsidies and loans | The PM Surya Ghar subsidy and cheap solar loans are what make rooftop solar affordable for most homes. Buyers search how to apply, how much they get, which bank lends, and whether societies and businesses qualify. Wrong answers here cost real money. |
| 3 | Choosing an installer | Choosing an installer is the most commercial decision in the journey. Buyers ask for the best company, how to find a registered vendor, what to check before signing, whether to buy or lease, and who installs on factories. Every answer names firms. |
| 4 | Net metering and approvals | Net metering and DISCOM approval decide whether a system earns its savings. Buyers search how net metering works, how to apply, how long approval takes, whether they can sell surplus power, and which system type to pick. Rules differ by state. |
| 5 | Living with rooftop solar | After installation, owners ask how to clean panels, how long they last, whether solar works in a power cut, what it produces in the monsoon and what warranty to demand. These answers shape trust in the product and in the installer. |
Category 1 of 5
Cost and savings
Five questions about money: what a 3 kW rooftop system costs in India, how much it cuts the electricity bill, how many years it takes to pay back, what size a home needs, and whether solar pays for a shop or factory.
