Independent TPDDL consumer guide
Prepare the consumer account, roof design, equipment evidence and safety documents together so the online application and installed plant describe the same system.
Fact-checked 10 August 2026
Applicant
Registered consumer
TPDDL’s current guidance requires the applicant to be the registered consumer, with authority documents where applicable.
Subsidy equipment
DCR + ALMM
Current TPDDL guidance states the applicable domestic-content and approved-list requirements for subsidy release.
Small systems
≤10kW
TPDDL’s current application guidance describes plants up to 10kW as deemed feasible, subject to the stated workflow and checks.
For an eligible residential subsidy project, equipment and installation must follow the official scheme and TPDDL route. TPDDL’s current online guidance expressly calls out DCR modules and applicable ALMM compliance for subsidy release.
| Area | Ready when | Common preventable issue |
|---|---|---|
| Consumer account | CA active, name/mobile/load confirmed | OTP or ownership mismatch |
| System design | Capacity, datasheets and SLD agree | Different inverter/module capacity across files |
| Subsidy route | National Portal/vendor/DCR/ALMM position confirmed | Assuming any module is automatically eligible |
| Safety | Isolation, ELCB/RCCB, earthing and meter provisions documented | Inspection-ready evidence prepared too late |
| Completion | Invoices, serial numbers, photos and as-built file organised | Installed system differs from approved submission |
Y2 Solar process
Validate the TPDDL CA number, registered consumer, mobile number, tariff category, sanctioned load and roof rights.
Survey the roof and consumption, then prepare the proposed capacity, layout, equipment selection and electrical route.
Submit the online application with the current identity, ownership, datasheet and single-line-diagram requirements.
Resolve feasibility or document observations and freeze the approved system before procurement.
Install with the specified equipment, structure, protection, earthing, isolation, labels and meter provisions.
Complete inspection, meter work, commissioning and subsidy follow-up through the official TPDDL/government process.
No. Y2 Solar is an independent Delhi rooftop solar installer. Tata Power-DDL is the distribution utility, while Tata Power Solar is a separate solar brand/business.
An eligible residential consumer can use the official scheme workflow, subject to the current vendor, DCR/ALMM, feasibility, inspection and commissioning conditions.
Current TPDDL guidance describes systems up to 10kW as deemed feasible, but the applicant must still follow the live portal, document, safety, meter and commissioning requirements.
Update or complete the required eKYC/account process through TPDDL before relying on OTP-based application steps.
Do not assume so. TPDDL’s current guidance calls for the applicable DCR and ALMM compliance for subsidy release. Verify the exact equipment evidence before procurement.
No. A standard grid-connected plant disconnects during an outage. Backup requires a separately designed hybrid inverter and storage arrangement.
