- The name on the EB / TNPDCL service connection does not match the name on Aadhaar or bank records.
- Bank details are wrong (account number or IFSC), or the account is inactive.
- Roof ownership proof is missing or is in a different name.
- The panels are not DCR/ALMM-listed, or the installer is not an empanelled vendor.
- The sanctioned load on the connection is lower than the solar system size.
- Photos or documents uploaded to the portal are unclear or incomplete.
