Start with the correct route
Tamil Nadu's rooftop portal distinguishes residential PM Surya Ghar applications from other solar services. Follow the current national and state instructions for your connection category. A commercial site should not assume that a residential benefit applies. Published amounts and process steps can change; obtain a dated confirmation before budgeting.
- Check your electricity-service details and applicant information.
- Open the official vendor directory and confirm the relevant registration.
- Retain application references and receipts.
What to agree before paying
INGAA planning checklist: request a written quotation that separates equipment, installation, metering-related work and support. Ask who handles portal submissions and how you receive copies. Keep any expected subsidy separate from the gross project cost until eligibility and payment conditions are established. Never share OTPs or account passwords in an informal enquiry form.
- Confirm ownership or permission to use the roof.
- Record the selected equipment and warranty documents.
- Track inspection, commissioning and application status through official channels.
