Navigating the DISCOM approval process is essential for legally installing rooftop solar in India and unlocking subsidies. This 4th blog post breaks it down step-by-step for hassle-free grid connection under PM Surya Ghar Muft Bijli Yojana.
Why DISCOM Approval Matters
DISCOMs (Distribution Companies) regulate grid-connected rooftop solar to ensure system safety, grid stability, and net metering eligibility. Skipping approvals risks fines, disconnection, or subsidy denial, as they verify feeder capacity and compliance with state regulations. In 2026, streamlined MNRE guidelines mandate approvals within 15-30 days to boost India’s 500 GW renewable target. Learn more on the MNRE website.

Step-by-Step DISCOM Approval Process
Follow these stages for rooftop solar DISCOM approval in India:
- Online Application Submission: Register on the National Portal or your state DISCOM portal (e.g., PSPCL for Punjab). Upload electricity bill (last 6 months), ID proof, site photos, and proposed system specs (1-10 kW capacity). Pay nominal fee (₹200-₹1000).
- Feasibility Check and Site Inspection: DISCOM schedules an engineer visit within 3-7 days to assess roof space, shading, transformer load, and wiring. They issue Technical Feasibility Approval if viable, specifying sanctioned solar capacity.
- Vendor Selection and Installation: Choose a DISCOM-registered vendor using ALMM-listed panels and BIS-certified inverters. Sign consumer-vendor agreement; install only after feasibility nod to avoid rejection. Check approved vendors on your DISCOM site.
- Net Metering Application: Submit single-line diagram, bill of quantities, completion report, system photos, and invoices via portal. DISCOM approves, installs bi-directional smart meter (often within 15 days), and verifies AC/DC wiring.
- Final Inspection and Commissioning: Post-installation inspection confirms compliance. DISCOM issues Synchronization Certificate and Commissioning Certificate, enabling grid export and subsidy release (within 30 days via DBT). Track subsidies on the national portal.
Documents Required for DISCOM Approval
Gather these essentials for quick processing—download checklists from your DISCOM portal:
| Document | Purpose | Key Tips |
| Electricity Bill (last 6 months) | Verify consumer & load details | Scan recent bills clearly |
| Aadhaar/PAN Card | KYC & subsidy linking | Link to bank account early |
| Site/Layout Plan & Photos | Assess roof space & shading | Include north-facing orientation |
| System Specs (Quotes/Agreement) | Confirm ALMM panels & BIS inverters | Get from registered vendor |
| Single-Line Diagram (SLD) | Validate wiring & safety | Submit post-installation |
| Bank Passbook/Cancelled Cheque | Direct subsidy transfer (DBT) | Mandatory for ₹78,000 CapEx grant |
Timelines and Common Delays
Expect 30-60 days total: 15 days for feasibility, 15 for net metering, 30 for subsidy. Delays arise from incomplete docs, meter shortages, or high demand—MNRE mandates DISCOMs stock smart meters. Pro tip: Track via portal and follow up weekly. Download full guidelines PDF.

State-Wise Variations
While national MNRE standards apply, check your state’s DISCOM for tweaks:
- Punjab (PSPCL): Fast online portal; verify feeder capacity at PSPCL.
- Gujarat (UGVCL/PGVCL): Quickest approvals (~20 days) with high solar adoption.
- Karnataka (BESCOM): Efficient net metering; vendor lists online.
- Delhi (TPDDL/BRPL): Extra SDO clearance needed; track via DISCOM app.
- Others: Maharashtra/Tamil Nadu follow suit—always use state portals for latest 2026 rules.
Tips to Speed Up Approval
- Use registered vendors—they handle paperwork.
- Ensure 20% shadow-free roof space per kW.
- Avoid peak monsoon for inspections.
- Track via National Portal for real-time status.
