Jaane solar system ka output kam kyu ho raha hai aur kaise sudharen. Step-by-step troubleshooting guide in Hindi for better solar efficiency.
☀️ Introduction
Aapne ghar ya business par solar system lagaya, pehle sab sahi chal raha tha…
Par ab aap notice kar rahe ho ki solar generation kam ho gaya hai.
Output me 20–30% drop ek common problem hai — lekin tension lene ki zarurat nahi.
Is blog me hum jaanenge:
✅ Solar system ka output kam hone ke reason
✅ Kaise check karein
✅ Step-by-step solution
⚡ Chapter 1: Solar Output Kam Hone Ke Common Reasons
Solar system ka performance kai factors par depend karta hai. Yahaan sabse common 10 causes diye gaye hain:
| Cause | Description | Solution |
|---|---|---|
| 1️⃣ Dust & Dirt | Panel par mitti aur bird droppings light block karte hain | Panel regular saaf karein |
| 2️⃣ Shading Issue | Tree, dish antenna, ya wire ki shadow | Panel area shadow-free rakhein |
| 3️⃣ Loose Connection | Wire ya MC4 connector loose | Electrical check-up karayein |
| 4️⃣ Inverter Error | Fault code aana ya trip hona | Manual check + service support |
| 5️⃣ Battery Issue (Off-grid) | Low voltage ya sulphation | Battery water & voltage test karein |
| 6️⃣ Low Sunlight / Weather | Cloudy season me irradiance kam | Seasonal variation normal hai |
| 7️⃣ Panel Ageing | Efficiency drop over years | Panel replacement consider karein |
| 8️⃣ Temperature Rise | High heat = low voltage | Ventilation improve karein |
| 9️⃣ Improper Tilt Angle | Wrong direction se sunlight loss | South-facing angle maintain karein |
| 🔟 MPPT/PWM Fault | Charge controller malfunction | Reset or replace controller |
🔍 Chapter 2: Step-by-Step Troubleshooting Guide
🔹 Step 1: Visual Inspection
- Dekhiye panel par dirt, bird droppings, ya crack to nahi.
- Wires aur junction box tight hai ya nahi.
- Inverter display par koi error code to nahi.
🔹 Step 2: Cleaning Test
Panel ko soft cloth aur clean water se saaf karein.
Zyada dust hone par 10–20% output loss hota hai.
🔹 Step 3: Inverter Reading Check
Inverter ka generation reading aur voltage check karein.
Agar inverter blinking light dikha raha hai → error code note karein.
🔹 Step 4: Shadow Mapping
Subah se shaam tak dekhein koi shadow to nahi pad rahi.
Ek chhoti si shadow bhi poore string ke output ko kam kar sakti hai.
🔹 Step 5: Voltage & Current Test
Multimeter se DC voltage aur current measure karein.
Ek panel me 18–22V hona chahiye (depending on wattage).
🔹 Step 6: Panel Temperature Check
High temperature me efficiency har 1°C par 0.4–0.5% girti hai.
Ensure airflow below panels.
⚙️ Chapter 3: Solar Generation Formula
Total Solar Output (Units/day) = System Size (kW) × Avg Sun Hours × Efficiency
Example:
5 kW system × 4.5 hrs × 0.8 = 18 units/day
Agar aapka output 18 se 10 unit tak gir gaya hai → 40% drop → zarur koi issue hai.
🔆 Chapter 4: How to Improve Solar Efficiency
✅ 1. Clean Regularly — Har 15 din me cleaning schedule rakhein
✅ 2. Maintain Tilt — South-facing 20–30° tilt best hai
✅ 3. Annual Service — Har saal technician se inspection
✅ 4. Monitor Performance — Smart inverter app use karein
✅ 5. Replace Faulty Panels — Crack ya micro damage panel hataayein
🔋 Chapter 5: Solar Inverter Error Codes (Example Table)
| Error Code | Meaning | Action |
|---|---|---|
| 101 | Grid Voltage Low | Wait until voltage normal |
| 201 | DC Over Voltage | Check PV array voltage |
| 301 | Earth Fault | Call technician |
| 401 | Over Temperature | Cooling improve karein |
| 501 | Isolation Fault | Wire insulation test karein |
🧠 Chapter 6: Preventive Maintenance Tips
1️⃣ Har 6 mahine me performance audit karayein
2️⃣ Inverter room ventilated rakhein
3️⃣ Wires par rodents se bachav karein
4️⃣ Lightning & SPD install karein
5️⃣ Solar app par daily generation track karein
🌞 Chapter 7: FAQs
Q1. Mera solar generation pehle 10 unit tha, ab 6 unit kyu ho gaya?
Dust, weather, ya inverter issue ho sakta hai. Panel cleaning aur inverter check karein.
Q2. Panel cleaning ke baad kitna improvement hota hai?
10–25% tak generation improve hota hai.
Q3. Cloudy din me output kam hona normal hai kya?
Haan, 30–40% tak drop normal hai.
Q4. Solar panel ki lifespan kitni hoti hai?
25 years tak, lekin 20 saal baad output 80% ke aaspaas hota hai.
Q5. MPPT controller kya karta hai?
Ye solar voltage aur current optimize karke battery ya inverter ko best power deta hai.
✅ Conclusion
Agar aapka solar power output kam ho raha hai, to ghabraiye nahi.
Zyada cases me issue simple maintenance ya wiring fault se solve ho jata hai.
👉 Har 15 din me panel saaf karein, inverter readings track karein aur annual service zarur karayein.
Solar system ek long-term investment hai — thoda maintenance, zyada fayda! ☀️
