TGSPDCL 10 kW Solar Waiver & PM Surya Ghar Subsidy Guide
TGSPDCL 10 kW No-Feasibility Waiver; PM Surya Ghar Subsidy Guide
Residential rooftop solar systems up to 10 kWp in Telangana do not require a technical feasibility study when the application is complete. This guide separates that exemption from TGSPDCL registration, load enhancement, metering and PM Surya Ghar subsidy requirements, so Hyderabad homeowners can manage each approval without confusing it with commissioning.
Does a residential system up to 10 kWp need feasibility approval?
Under TGERC's Rooftop Solar PV Grid Interactive Systems Regulation, effective November 15, 2025, complete applications up to 10 kWp are deemed accepted without a technical feasibility study. The regulation also provides deemed approval where an application is not acted upon within 15 working days. That is a statutory backstop-not a mandatory waiting period for an exempt installation. (tgerc.telangana.gov.in)
TGSPDCL has announced an application-fee waiver for eligible systems up to 10 kWp registered between June 22, 2026 and March 31, 2027, subject to applicable conditions. Confirm eligibility against your registration date; the application-fee waiver does not automatically waive meter, testing or load-related charges.
A TGSPDCL no-feasibility waiver removes the study requirement, not electrical safety checks or permission to synchronise with the grid. Keep the completed application acknowledgement as evidence of submission.
Complete the application and installation steps
Check sanctioned load before fixing capacity. For LT-I domestic consumers, permissible rooftop capacity is capped at 100% of sanctioned load. If the proposal exceeds it, request solar load enhancement through TGSPDCL's consumer-service portal and link the request to the solar application. For systems up to 10 kWp, the regulation requires the DISCOM to carry out commensurate enhancement; ask whether the integrated application handles this automatically before filing a duplicate request.
Register with the correct DISCOM. On the National Portal, select Telangana, the distributor shown on your bill and the correct consumer number. Retain both national and local acknowledgement numbers. TGNPDCL residential solar net metering applicants must select TGNPDCL rather than follow TGSPDCL-specific field arrangements.
Verify vendor and equipment eligibility. Choose a vendor registered for your DISCOM on the National Portal and verify current TGREDCO/TGSPDCL empanelment where applicable. Subsidised installations require DCR-compliant modules manufactured in India using domestically manufactured cells. Check module ALMM listing and applicable ALMM List-II cell requirements; retain declarations and serial numbers rather than relying on a Made in India label.
Close installation, metering and commissioning together. Have the installer submit completion records and coordinate inspection, meter testing and installation. For the net metering agreement format in Telangana, use the current official form or digital workflow-not an old downloaded template. TGSPDCL has reported document exemptions, including agreement-related exemptions, so confirm what your application actually requires.
Track National Portal and TGSPDCL actions separately
Use this sequence to identify which organisation owns the next action. Portal registration alone does not establish that the field work is complete. The national process ends with commissioning records and the consumer's subsidy claim.
Stage | National Portal action | TGSPDCL/local action |
|---|---|---|
1. Register | Enter consumer, mobile and DISCOM details | Verify service and sanctioned load |
2. Apply | Submit rooftop application; retain ID | Record complete application and applicable exemption |
3. Prepare | Select registered vendor | Resolve load enhancement and metering requirements |
4. Install | Upload plant details | Check completion and protection records |
5. Meter | Submit net-meter request | Test, install and seal approved meter; inspect system |
6. Commission | Obtain commissioning certificate | Confirm inspection and commissioning |
7. Claim | Submit bank details and cancelled cheque | Correct missing commissioning entries if flagged |
This table follows the national registration-to-subsidy sequence; local document requirements must match the current TGSPDCL workflow.
Calculate subsidy and Hyderabad payback
PM Surya Ghar provides residential CFA through direct benefit transfer: ₹30,000 for 1 kW, ₹60,000 for 2 kW and ₹78,000 for 3 kW or above. A 5 kW or 10 kW installation does not receive additional CFA beyond that ceiling.
The following is an illustrative Hyderabad budgeting calculation, not a market quotation. Assume ₹60,000/kW installed cost, 1,400 kWh/kW annual generation and every generated unit offsetting purchases valued at ₹9.50/₹10.00. These are modelling inputs, not guaranteed production or a universal LT-I tariff.
Capacity | Assumed cost | CFA | Net cost | Annual savings | Simple payback |
|---|---|---|---|---|---|
3 kW | ₹1,80,000 | ₹78,000 | ₹1,02,000 | ₹39,900 to ₹42,000 | 2.4 to 2.6 years |
5 kW | ₹3,00,000 | ₹78,000 | ₹2,22,000 | ₹66,500 to ₹70,000 | 3.2 to 3.3 years |
10 kW | ₹6,00,000 | ₹78,000 | ₹5,22,000 | ₹1,33,000 to ₹1,40,000 | 3.7–3.9 years |
Calculate payback as net cost divided by annual savings. Replace assumptions with quotations, your consumption profile and applicable tariff; include maintenance, finance and extra electrical works. Do not value surplus exports automatically at retail tariff: settlement follows TGERC rules.
What should you do when the meter or subsidy is delayed?
Identify the pending stage before escalating. For a residential solar net meter delay at TGSPDCL, distinguish meter availability, MRT testing, installation and commissioning upload. Ask whether DISCOM supply or consumer procurement of an approved bi-directional meter is available; self-procurement can avoid a stock-out, but cannot bypass testing or sealing. Confirm specifications before purchase and obtain itemised bi-directional meter charges from TGSPDCL.
For PM Surya Ghar subsidy status in Telangana, check commissioning and bank-validation entries separately. Submit an active account, correct IFSC and cancelled cheque; verify Aadhaar linkage if requested. Official guidance describes payment within 30 days after commissioning and submission of bank details-not certificate issuance alone. PFMS integration now supports faster release, but rejected bank details still require correction.
FAQs
Q1) What does the TGSPDCL no-feasibility waiver actually waive?
It waives the requirement for a prolonged technical feasibility study for residential applications up to 10 kWp when the application is complete under the applicable TGERC rooftop solar regulation. It does not waive site inspection, protection verification, meter testing/sealing, synchronisation permission, or billing integration.
Q2) Is deemed approval in 15 working days the same as commissioning permission?
No. Deemed approval (where applicable) addresses application disposal timelines. Commissioning still requires completion of inspection, bi-directional meter installation (or replacement), sealing, and update of commissioning in the relevant system before energy accounting can begin.
Q3) I am an LT-I domestic consumer. Can I install 5 kW if my sanctioned load is 3 kW?
Not without addressing the cap. For LT-I domestic connections, permissible rooftop PV capacity is capped at 100% of sanctioned load. You must initiate an online Load Enhancement request (on TGSPDCL systems) so the sanctioned load is commensurately enhanced and the solar capacity becomes admissible.
Q4) Is the 10 kW waiver applicable to commercial (C&I) connections?
This guide is for residential domestic rooftop solar. Do not apply residential thresholds and waiver logic to C&I services; the governing caps, approvals, and settlement conditions differ by category and regulation.
Q5) Why is my net meter taking time even after the portal shows approval?
The most common bottleneck is bi-directional (importexport) meter availability and the downstream workflow: field inspection by the Section Officer/AE, forwarding to ADE, and scheduling of meter testing and sealing. If the meter is routed via MRT testing, queue times can extend commissioning.
Q6) What is MRT testing, and where does it typically happen in Hyderabad?
MRT (Meter Relay Testing) is the DISCOM process to verify meter type, accuracy class, sealing, and configuration suitability for importexport energy accounting. Testing may be performed at the designated TGSPDCL MRT facility/division serving your area (for example, commonly referenced labs include Mint Compound/Erragadda and other regional testing divisions, subject to TGSPDCL routing).
Q7) Can I buy a bi-directional meter myself to avoid stock-out delays?
In many cases, yes-if TGSPDCL permits consumer procurement for your service and the meter conforms to TGSPDCL-approved specifications and is accepted for MRT testing/sealing. Consumer procurement may reduce waiting for meter stock, but it does not eliminate testing, sealing, and commissioning formalities.
Q8) What are bi-directional meter charges and who pays them?
Charges depend on the meter type, procurement route (DISCOM-supplied vs consumer-procured), and applicable schedule of charges. Obtain the current itemised demand/fee breakup from TGSPDCL for your service, and do not assume the application-fee waiver covers meter/testing-related costs.
Q9) What exactly is the PM Surya Ghar subsidy amount, and does it increase beyond 3 kW?
The CFA is a flat DBT structure: 'e30,000 for 1 kW, 'e60,000 for 2 kW, and a fixed ceiling of 'e78,000 for 3 kW and above. There is no higher CFA for 5 kW or 10 kW beyond the 'e78,000 cap.
Q10) What are the non-negotiable eligibility conditions for PM Surya Ghar CFA?
The installation must be executed through a registered/empanelled vendor (as applicable for the DISCOM/state workflow), and the modules must satisfy DCR requirements and be listed on the ALMM as required at the time of procurement/installation. Keep traceability records (make/model, serial numbers, invoices, declarations) for auditability.
Q11) When will the PM Surya Ghar subsidy be credited, and to whose bank account?
The CFA is credited via PFMS as a DBT to the applicant's Aadhaar-linked bank account, typically within 30 days of DISCOM commissioning certificate generation, provided bank details validation is successful and the commissioning data is correctly reflected.
Q12) Will exported (surplus) solar energy always be valued at my retail tariff?
No. Energy accounting and settlement follow the applicable TGERC methodology for rooftop net metering/billing. Treat export compensation as a regulated settlement item; do not model exports at the highest domestic retail slab unless the regulation explicitly provides for it in your case.
