Rooftop Solar Installation Process in Telangana: Step-by-Step Guide (2025)
Switching to rooftop solar is one of the smartest investments for homes in Telangana. But many homeowners hesitate because they don’t know how the actual installation process works — approvals, survey, net metering, subsidy steps, and timeline.
This guide simplifies everything for you.
Whether you are from Hyderabad, Warangal, Karimnagar, Nizamabad, Khammam, or any Telangana district, this blog explains the complete rooftop solar installation process followed by DISCOMs and TSREDCO in 2025.
🔹 Step 1: Initial Consultation & Requirement Understanding
The process starts when the customer contacts a solar provider like Soura Solar Solutions.
During this stage:
- Your energy consumption is assessed
- Your recent electricity bills are reviewed
- Ideal system capacity (1–3kW / 3–5kW / 5–10kW) is suggested
- Basic roof suitability is checked using satellite imagery
- Subsidy eligibility is confirmed
This initial call is usually completed in 10–15 minutes.
🔹 Step 2: Site Survey & Technical Assessment
A technician visits your location to conduct a detailed assessment.
The survey includes:
✔ Roof direction (south-facing is ideal)
✔ Shadow analysis using solar tools
✔ Roof strength & dimensions
✔ Cable routing plan
✔ Earthing point possibility
✔ Net meter feasibility
This inspection ensures that the solar system is designed perfectly for maximum output.
Survey duration: 20–45 minutes
Outcome: A precise system design + final quotation.
🔹 Step 3: Final Proposal, Quotation & Subsidy Guidance
After the survey, you receive a complete proposal with:
- Total system capacity
- Cost before subsidy
- Available Telangana/PM Surya Ghar subsidy
- Net effective cost
- EMI options (if applicable)
- Warranty details
- Required documents
Your installer also guides you through National Portal Registration for subsidies.
🔹 Step 4: Application on the National Solar Portal
In Telangana, all rooftop solar subsidy requests are submitted on the National Portal for Rooftop Solar (MNRE).
You must upload:
- Aadhar-linked mobile number
- Electricity bill
- Property proof (if required)
- Bank details
- Photo of your roof (optional)
After submission, your DISCOM (TSSPDCL/TSNPDCL) reviews the application.
Approval time: 3–10 days
🔹 Step 5: Installation of the Solar System
Once DISCOM approves, the installer begins the installation.
The installation includes:
- Mounting structure fixing
- Module installation
- Inverter placement (hybrid/on-grid)
- DC & AC wiring
- Earthing
- SPD, MCB, ACDB, DCDB setup
- System testing
Installation time:
- 1–2 days for 1–3 kW
- 2–3 days for 3–5 kW
- 3–5 days for 5–10 kW
All work follows safety standards and government-approved specifications.
🔹 Step 6: Net Metering Application & Approval
After installation, your installer applies for a net meter.
Net meter allows you to:
- Export extra solar power to the grid
- Earn credits on your bill
- Reduce monthly electricity charges significantly
TSREDCO/TSSPDCL verifies the installation and approves the meter.
Net meter installation timeline: 7–25 days (depending on DISCOM load)
🔹 Step 7: System Inspection & Commissioning
DISCOM authorities will inspect the solar setup and check:
- Wiring quality
- Safety compliance
- Earthing
- Module placement
- Inverter performance
Once approved, the system is commissioned.
You then start generating your own green energy immediately!
🔹 Step 8: Subsidy Claim & Transfer
After commissioning, all documents are uploaded to the national portal:
- Project completion report
- Net metering approval
- Installer details
- Customer bank details
MNRE verifies the system and releases the subsidy directly to the customer’s bank account.
Subsidy disbursal time:
30–90 days (varies based on MNRE queue)
