Solar Earthing क्यों जरूरी है? Chemical Earthing vs GI Earthing क्या फर्क है? Price, Material List और Earthing Installation Guide पूरी Detail में जानें।
⚡ Solar Earthing क्या है?
जब Solar System से Fault Current निकलता है, Earthing System उसे Safe तरीके से Ground में Transfer कर देता है
ताकि:
✔ Electric Shocks न हों
✔ Inverter Safe रहे
✔ Lightning Damage न करे
Earthing = आपका Solar System का सुरक्षा कवच 🔰
🌩 Earthing क्यों इतनी जरूरी है?
| Risk | Without Earthing | With Earthing |
|---|---|---|
| Lightning | System Damage | Protection |
| Over Voltage | Inverter Burn | Safe Cut-Off |
| Fire Risk | High | Zero |
| Shock | Danger | Safe ✅ |
📌 Govt. Rooftop Solar Installation में Earthing Mandatory है।
🛠 Solar Earthing के Types
| Type | Best For | Life | Cost |
|---|---|---|---|
| GI Earthing (Pipe/Rod) | Homes | 8–10 Years | Low |
| Chemical Earthing | Commercial/Industrial | 15–25 Years | Medium |
| Plate Earthing | Heavy Load Areas | 20+ Years | High |
| Maintenance-Free Earthing | Solar Farms | 30+ Years | High |
👉 Home Solar = Chemical or GI Earthing सबसे अच्छा ✅
🧾 Solar Earthing Materials List
✔ Earthing Rod/Pipe (GI/Copper)
✔ Charcoal + Salt (GI Method)
✔ Backfill Compound (Chemical Method)
✔ Earthing Strip/Wire
✔ Earth Pit Chamber
✔ Test Link
✔ Lightning Arrester (Optional)
🧱 Installation Process (Step-by-Step)
1️⃣ 8–10 फीट गड्ढा खोदें
2️⃣ Pipe/Rod सही Depth पर Fix करें
3️⃣ Earthing Compound (या Charcoal + नमक) Fill करें
4️⃣ Earthing Wire से Solar Inverter & Structure Connect करें
5️⃣ Earth Pit Chamber से Testing Point बनाएं
6️⃣ Earthing Value Measure करें
📌 Standard Earthing Resistance Value: < 1 Ohm ✅
💰 Solar Earthing Cost (2025 India)
| Earthing Type | Home Rooftop | Commercial |
|---|---|---|
| GI Earthing | ₹3,000 – ₹6,000 | ₹6,000 – ₹10,000 |
| Chemical Earthing | ₹8,000 – ₹15,000 | ₹15,000 – ₹30,000 |
| Lightning Arrester | ₹4,000 – ₹12,000 | ₹20,000+ |
✅ Bigger System → Multiple Earthing Points Required
⚠️ Earthing में Common Faults
| Fault | Cause | Result |
|---|---|---|
| Resistance High | Soil Dry | Shock Risk |
| Rusting | Wrong Material | Conductor Fail |
| Loose Connection | Poor Labor | No Protection |
| No Maintenance | Dust & Water | Damage Increase |
🧪 Earthing Testing & Certificate
✔ Earth Resistance Tester से Regular Testing
✔ DISCOM या EPC Contractor Certificate Provide करता है
✔ Net Metering के लिए Mandatory
📌 हर 6 महीने में Testing Required ✅
✅ Conclusion
सही Solar Earthing = Solar System की Life + Safety + Output का Assurance
✔ Fire Risk Zero
✔ Lightning Protection
✔ Inverter Health Safe
✔ Govt. Safety Standard Follow
