TSSPDCL Net Metering Documents Checklist 2026 — Complete Application Guide for Hyderabad
Net metering is the mechanism that allows your solar system to earn credits for electricity exported to the grid. Without it, your solar investment is incomplete — you cannot offset your electricity bills legally or systematically. This guide provides the complete TSSPDCL net metering documents checklist, the step-by-step process, and everything you need to avoid rejection.
TSSPDCL vs TSNPDCL — Which DISCOM Applies to You?
Telangana has two power distribution companies for solar net metering. Your district determines which one handles your application:
| DISCOM | Full Name | Districts Covered |
|---|---|---|
| TSSPDCL | Telangana Southern Power Distribution Company Ltd. | Hyderabad, Rangareddy, Mahbubnagar, Nalgonda, Khammam |
| TSNPDCL | Telangana Northern Power Distribution Company Ltd. | Warangal, Karimnagar, Nizamabad, Adilabad, Medak (northern districts) |
The document checklist and process are identical for both DISCOMs. The only difference is the office where you submit the application. If you are in Hyderabad, Secunderabad, or Rangareddy district, you are under TSSPDCL.
Complete TSSPDCL Net Metering Documents Checklist 2026
Prepare all of the following before submitting your application. Missing even one document is the most common cause of delays and rejection.
Category A — Consumer Identity Documents
| # | Document | Notes |

| 11 | Electrical inspector's test certificate (if applicable) | Required for systems above 10kW or where the DISCOM specifically requests it |
Category C — Net Meter Documents
| # | Document | Notes |
|---|---|---|
| 12 | Net meter purchase receipt / invoice | Consumer typically purchases the bidirectional net meter from a TSSPDCL-approved vendor (cost ~₹4,000–₹6,000). Your installer arranges this. |
| 13 | Net meter test report | Test certificate from an accredited lab confirming the meter meets IS 16444 standards |
| 14 | Completed TSSPDCL net metering application form | Available from TSSPDCL offices or via the installer. Must be signed by the consumer and the installer. |
Step-by-Step TSSPDCL Net Metering Process — 7 Steps
-
Solar Installation & Energization (Day 0–2)
Sri Ishaan Solar installs the solar panels, inverter, and cabling on your roof. The system is energized and tested. The inverter's anti-islanding protection is verified. At this point the system is generating power but is not yet connected to the net metering arrangement. -
Document Preparation (Day 2–5)
We prepare the complete document set: single-line diagram, installation certificate, TGREDCO registration copy, and the net metering application form. We also arrange the net meter purchase from a TSSPDCL-approved supplier. -
PM Surya Ghar Portal Update (Day 3–5)
The installation is updated on pmsuryaghar.gov.in with the as-built system details. This is required for the PMSG subsidy and also forms part of TSSPDCL's verification for net metering. -
Net Metering Application Submission to TSSPDCL (Day 5–7)
We submit the complete application package to the relevant TSSPDCL section office (typically the Assistant Divisional Engineer's office for your area). Applications for Hyderabad are typically submitted at the respective circle offices in Ameerpet, Musheerabad, Malakpet, or the applicable subdivision. -
TSSPDCL Technical Inspection (Day 10–20)
A TSSPDCL lineman or Assistant Engineer visits your premises to inspect the solar installation. They verify that the installed system matches the single-line diagram, that the inverter is grid-compatible, and that earthing and safety standards are met. -
Sanction Order and Net Meter Installation (Day 20–35)
After a successful inspection, TSSPDCL issues a sanction order. The old energy meter is replaced with a bidirectional net meter. This meter records import (grid to home) and export (home to grid) separately. -
Commissioning Certificate and Subsidy (Day 35–45)
TSSPDCL issues a commissioning certificate confirming the solar system is officially connected. This certificate is uploaded to the PM Surya Ghar portal to trigger the PMSG subsidy credit of ₹78,000 to your bank account. From this point, your electricity bills reflect net metering credits.
Common Rejection Reasons and How to Avoid Them
| Rejection Reason | How to Avoid |
|---|---|
| Installer not registered with TGREDCO | Always use a TGREDCO-registered vendor. Sri Ishaan Solar Reg: TSRE260936. Verify your installer's registration before signing any contract. |
| System capacity exceeds sanctioned load | Net metering is typically sanctioned up to the consumer's sanctioned load in kW. If your sanctioned load is 5kW, do not install a system larger than 5kW without first applying for load enhancement. |
| Inverter not on MNRE approved list | Sri Ishaan Solar uses only MNRE-listed inverters. Confirm this before purchase — it is a non-negotiable requirement. |
| Mismatch between SLD and actual installation | The single-line diagram must exactly reflect the as-built system. Any last-minute changes to panel count or inverter model must be reflected in an updated SLD before submission. |
| Incomplete or illegible application form | Have the installer fill and verify the form. All signatures (consumer + installer) must be in ink. Photocopied signatures are not accepted. |
| Net meter not from an approved supplier or missing test certificate | The net meter must meet IS 16444 and come with a valid test report. Sri Ishaan Solar sources meters from TSSPDCL-approved vendors by default. |
| Name mismatch across documents | The name on the electricity bill, Aadhaar, and property documents must all match. If there is a minor variation (e.g., initials vs full name), attach an affidavit explaining the discrepancy. |
How Net Metering Benefits You — After Installation
Once the net meter is installed, here is how your monthly billing works:
- Import reading: Units drawn from the grid (at night and on cloudy days)
- Export reading: Units your solar system sends to the grid (excess daytime generation)
- Net units billed: Import minus export. If you export more than you import in a month, the surplus credits carry forward to the next month.
- Fixed charges: You still pay the minimum fixed charge (roughly ₹50–₹100/month) regardless of generation. This is the base DISCOM connection charge.
A well-sized 5kW solar system in Hyderabad can bring your monthly electricity bill from ₹5,000–₹8,000 down to the minimum fixed charge of ₹50–₹100 during summer months when irradiance is highest. Winter bills may be slightly higher due to reduced generation on shorter days.

Frequently Asked Questions
What documents are needed for TSSPDCL net metering in Hyderabad?
Key documents: latest electricity bill, Aadhaar and PAN card, property ownership proof, completed net metering application form, TGREDCO-registered installer's certificate, single-line diagram, inverter and panel datasheets, installation completion certificate, and net meter purchase receipt with test certificate.
How long does TSSPDCL net metering take in 2026?
Typically 30–45 days from application submission to net meter installation. Sri Ishaan Solar follows up at each stage to prevent unnecessary delays. The commissioning certificate comes 3–5 days after net meter installation, triggering the PMSG subsidy credit.
What is the difference between TSSPDCL and TSNPDCL?
TSSPDCL covers Hyderabad city, Rangareddy, Mahbubnagar, Nalgonda, and Khammam (southern Telangana). TSNPDCL covers Warangal, Karimnagar, Nizamabad, Adilabad, and northern Telangana. The document requirements and process are the same for both.
Why do TSSPDCL net metering applications get rejected?
Common reasons: installer not TGREDCO-registered, system capacity exceeding sanctioned load, inverter not in MNRE's approved list, SLD mismatch with actual installation, missing net meter test certificate, or name mismatch between documents. Sri Ishaan Solar's pre-submission checklist prevents all these issues.
Can I apply for net metering before the solar installation is complete?
No. The net metering application is submitted after installation and energization. TSSPDCL sends a technician to inspect the actual installed system. However, a feasibility sanction from TSSPDCL should be obtained before or during installation to confirm grid connectivity approval — Sri Ishaan Solar handles this.
