How to Get DISCOM Approval for Solar in Telangana — 2026
Updated April 2026 | By Sri Ishaan Solar Team
Telangana లో solar install చేయాలంటే DISCOM (TSSPDCL/TSNPDCL) approval mandatory. Net metering, PM Surya Ghar subsidy — everything DISCOM approval based. ఈ guide లో full process, documents, timeline, common problems & solutions.
DISCOM Approval ఎందుకు అవసరం?
- Safety: Grid-connected systems grid safety standards follow చేయాలి
- Net metering: Bidirectional meter install చేయడానికి DISCOM approval కావాలి
- Subsidy: PM Surya Ghar subsidy DISCOM approval without process అవ్వదు
- Legal: Unauthorized grid connection = penalty + disconnection risk
Step-by-Step DISCOM Approval Process
Step 1: Application Submission
Timeline: Day 1
TSSPDCL/TSNPDCL online portal లో application submit. Required information:
- Consumer number & service connection details
- Proposed system size (KW)
- Vendor details (empanelment number)
- Single line diagram (SLD)
- Panel & inverter specifications
Note: Sri Ishaan Solar application preparation + submission handle చేస్తుంది.
Step 2: Technical Feasibility Study
Timeline: Day 1-15
DISCOM engineer checks:
- Transformer capacity — connected load vs available capacity
- Voltage levels at point of connection
- Grid stability in the area
- Cable size adequacy
Step 3: Feasibility Report & Approval
Timeline: Day 15-20
Positive report → approval letter with conditions. Negative report → reasons stated, solutions suggested.
Step 4: Installation Permission
Timeline: Day 20-25
Approval letter receive → installation begin. Approved specifications exactly follow చేయాలి.
Step 5: Installation Completion & Report
Timeline: Day 25-40
Installation complete → completion report submit with:
- Installation photos (all stages)
- Panel serial numbers
- Inverter test reports
- Earthing test certificate
- Insulation test results
Step 6: DISCOM Inspection
Timeline: Day 40-50
DISCOM inspector site visit → physical verification → safety compliance → meter testing.
Step 7: Bidirectional Meter & Commissioning
Timeline: Day 50-60
Old meter replace → bidirectional meter install → final readings → commissioning certificate.

Common Rejection Reasons & Solutions
1. Transformer Capacity Full
Problem: Local transformer already at maximum capacity — new solar connection not possible.
Solution: Request transformer upgrade (takes 2-3 months), or reduce proposed system size to fit available capacity.
2. Technical Issues — Voltage
Problem: Grid voltage at your location already high — additional solar injection will exceed limits.
Solution: Install voltage regulation equipment, or reduce system size.
3. Incomplete Documentation
Problem: Missing documents or incorrect specifications.
Solution: We prepare all technical documents — this never happens with Sri Ishaan Solar.
4. Non-Empanelled Vendor
Problem: Vendor not registered with MNRE/TSREDCO — automatic rejection.
Solution: Always use empanelled vendor. Sri Ishaan Solar is fully empanelled.
