Aaj India me solar lagane ka sabse bada reason sirf bijli bachana nahi, balki extra electricity ko grid me bech kar bill ₹0 ya negative karna hota hai.
Ye sab possible hota hai Net Metering System ke through.
Agar aap rooftop solar lagane ki planning kar rahe ho, toh aapko sabse pehle yeh samajhna zaroori hai:
- Net metering ka process kya hota hai?
- Net meter kaise lagta hai?
- Bill kaise calculate hota hai?
- Import-export ka kya rule hai?
- DISCOM ka role kya hota hai?
- 2025 ke naye rules kya hain?
Chaliye puri detail mai samajhte hain.
#️⃣ 1. Net Metering Kya Hota Hai?
Net Metering ek billing mechanism hai jisme aapke solar panels se generate hui extra electricity grid me export hoti hai, aur jab aapko light chahiye hoti hai toh aap grid se import kar sakte ho.
End of the month:
👉 Import – Export = Your Final Bill
Isliye ise “Net Metering” kaha jata hai.
#️⃣ 2. Net Meter Kaise Kaam Karta Hai?
Net meter ek bi-directional meter hota hai jo:
✔ Grid se kitni electricity li – Import
✔ Solar se grid me kitni electricity bheji – Export
Dono ko alag-alag measure karta hai.
Step-by-Step Working
Step 1 → Solar Panel Power Generate Karta Hai
Din me solar panel produce karta hai electricity.
Step 2 → Ghar Ki Load Ko Supply Hoti Hai
Sabse pehle solar se ghar ke loads (fan, light, AC, fridge) chalenge.
Step 3 → Extra Power Grid Me Chali Jaati Hai
Agar solar production > consumption →
Excess power grid me export ho jaati hai.
Step 4 → Raat Ko Grid Se Electricity Milti Hai
Raat me solar produce nahi karega →
Aap grid se light loge → Import.
Step 5 → Bill Me Sirf Net Units Count Hoti Hain
End me bill hoga:
Import Units – Export Units = Billable Units
Agar export > import →
Aapka bill ₹0 ya Negative ho sakta hai.
#️⃣ 3. Example: Net Meter Bill Calculation
Example
Import units: 150 units
Export units: 120 units
Net bill = 150 – 120 = 30 units
Agar per unit ₹6 hai →
Bill = ₹180
Profit Example
Import: 120 units
Export: 180 units
Net = 120 – 180 = –60 units
Aapka bill Zero + next month carry forward.
#️⃣ 4. India Me Net Metering Ke Rules (2025)
| Load (kW) | Net Metering Allowed? |
|---|---|
| 1–10 kW | ✔ Allowed |
| 10–200 kW | ✔ Allowed with limits |
| 200 kW+ | ✔ Gross metering recommended |
Residential Category me net metering fully allowed.
Commercial/Industrial me state-wise limitations hote hain.
#️⃣ 5. Net Metering vs Gross Metering Difference
| Feature | Net Metering | Gross Metering |
|---|---|---|
| Power Usage | Pehle ghar use karega | Saari power grid ko jayegi |
| Profit | High | Low |
| Best For | Residential | Factories/Commercial |
| Bill | Import–Export | DISCOM fixed rate |
#️⃣ 6. Net Metering Install Karne Ka Process
Step 1: Solar Rooftop Apply Karein
Government portal ya installer ke through.
Step 2: Technical Inspection
DISCOM team rooftop inspect karegi.
Step 3: Net Meter Approval
Appropriate load & wiring check.
Step 4: Net Meter Installation
Bi-directional meter lagaya jata hai.
Step 5: Commissioning Certificate
System officially activate hota hai.
Total time: 10–30 days (State-wise vary)
#️⃣ 7. Net Meter Installation Cost Kitna Hota Hai?
State wise vary karta hai.
| State | Approx Charges |
|---|---|
| Delhi | ₹400 – ₹800 |
| UP | ₹500 – ₹1000 |
| Haryana | ₹300 – ₹700 |
| Rajasthan | ₹500 – ₹900 |
| Maharashtra | ₹600 – ₹1200 |
#️⃣ 8. Net Metering Ke Benefits
✔ Bijli ka bill almost ₹0
✔ Extra units next month carry forward
✔ ROI fast ho jata hai
✔ Battery ki zaroorat nahi
✔ Environment friendly
✔ Government subsidy compatible
#️⃣ 9. Net Metering Ke Nuksan (Cons)
✘ Raat me solar kaam nahi karta
✘ Power cut me solar band ho jata hai
✘ DISCOM approval slow ho sakta hai
✘ Export limit hoti hai (state wise)
#️⃣ 10. Net Metering Lagane Ke Liye Documents
- Aadhar card
- Address proof
- Recent electricity bill
- Property ownership proof
- Installation layout
- Installer certifications
#️⃣ 11. Net Meter, Gross Meter & Smart Meter Difference
| Meter Type | Use Case |
|---|---|
| Net Meter | Home rooftop solar |
| Gross Meter | Commercial plant |
| Smart Meter | Automatic billing |
#️⃣ 12. Net Metering Kis Capacity Tak Allowed Hai?
Residential: 1 kW – 10 kW
Society/Apartment: 500 kW
Commercial: State-wise limit
#️⃣ 13. 3kW Solar System Me Net Metering Kaise Kaam Karta Hai?
3kW approx 12–14 units/day produce karta hai.
Agar aap ghar me 10 units daily use karte ho:
- 10 units use hogi
- 2–4 units export hogi
Monthly approx saving:
👉 ₹1800 – ₹2200
#️⃣ 14. Net Metering Ka Bill Kaise Aata Hai?
Bill me 3 cheeze hoti hain:
1) Import Units
2) Export Units
3) Net Units
= Import – Export
Fixed charge lagta hai (₹50–200/month).
#️⃣ 15. Conclusion
Net metering solar system ka sabse important part hai. Ye ensure karta hai ki:
- aapka ghar solar se chalta rahe
- extra electricity bech kar bill ₹0 ho
- investment jaldi recover ho
Agar aap solar rooftop lagana chahte ho, toh net metering must-have feature hai.
FAQs – Net Metering Kaise Kaam Karta Hai?
