Pehle saal solar pump ya chhat wala plant achha unit de raha tha. Ab lagta hai 30–40% kam — bill utna nahi gira, ya pump solar par kam chalti hai. Panel "kharab" bolne se pehle ye 7 reasons check karo. Zyada fix saste hain; ignore karoge to poore life mein lakhon ka nuksan.
Ye checklist PM-KUSUM pump, khet ki chhat, aur chhote plant sab par lagti hai. Dhool detail ke liye dhool cleaning guide dekho.
Ek raat mein achanak generation giri? Pehle inverter fault code — panel "mar gaye" assume mat karo.
Reason 1 — Dhool (soiling)
Rajasthan, Gujarat, UP, Haryana mein katai aur hawa ke baad dhool ki parat — bird droppings bhi.
| Halat | Loss |
|---|---|
| Halki dhool | 5–10% |
| 4 hafte barish nahi | 15–25% |
| Tractor ke paas mitti | 20–35% |
Fix: Subah thande panel par paani + soft brush. Dry season mein mahine mein ek baar; kachchi sadak ke paas weekly. Dhool guide aur barish-dhool tips.
Reason 2 — Shade (ped / building)
Ek shaded cell poori string ko kheench sakta hai.
Farm par common:
- Neem / eucalyptus badh gaya
- Naya tanki, murgi farm, bhus ka dher
- Agrivoltaics ka shadow purane panel par
- Bijli ka khambha subah/shaam
Fix: Ped trim (jahan allowed); obstacle hatao; permanent shade ho to re-string vendor se. 9 baje, 12 baje, 3 baje site dekho.
Reason 3 — Inverter fault / galat setting
Grid issue, garmi, ya export limit se inverter limit mode mein.
Check karo:
- Fault code photo
- DISCOM ne export cap lagaya? (jaise 70%)
- Fan par makdi ka jala — overheat
- App offline — problem tab pata jab bill aaye
Fix: Vent saaf, grid stable par reset, authorised service. Grid pump: inverter trip fix.
Reason 4 — Galat tilt / direction
India mein panel south face + tilt (~latitude angle). Flat chhat par 10–15% saal bhar loss.
| Galti | Asar |
|---|---|
| 0° flat | Sardi mein kam |
| Galat direction | Subah ya dopahar weak |
Fix: Naya install — vendor simulation. Purana — bracket ho to season mein tilt adjust; warna accept ya next service par re-mount.
Reason 5 — Curtailment (grid export band)
Grid full ho to DISCOM curtailment — inverter export kam ya band. Rajasthan aur high-solar state mein dopahar shutdown ki shikayat common.
Signs: App par 11–2 baje zero export; same feeder par aur log bol rahe hain.
Fix: Panel issue nahi — DISCOM complaint + log. Detail: Rajasthan curtailment. Battery/hybrid pehle cost dekho.
Reason 6 — Ageing (purane panel)
Achhe panel 0.5–0.8% / saal lose karte hain. 8–10 saal baad 5–8% kam normal — 40% nahi.
Shak ho to: brown cell (hot spot), pani andar, ek string bahut kam monitoring mein.
Fix: Vendor thermal scan; warranty claim; sirf kharab module badlo, poora plant nahi.
Reason 7 — Monitoring nahi (pata hi nahi chalta)
Install ke baad app kabhi khola nahi — jab tak bill na aaye.
Minimum habit:
- Roz ya hafte mein kWh note
- Pichhle saal same month se compare
- Toofan / katai ke next day check
- Inverter ke paas vendor number chipkao
App nahi to meter reading hafte mein manual.
Quick table — symptom se reason
| Symptom | Reason | Pehla step |
|---|---|---|
| Dheere-dheere kam | Dhool | Panel saaf |
| Barish ke baad phir kam | Dhool wapas | Dhulai + neeche paani check |
| Ek string kam | Shade / loose wire | Dekho + electrician |
| Dopahar zero, sun strong | Curtailment | DISCOM ticket |
| Saal 1 se hi sab kam | Tilt / design | Vendor review |
| 8+ saal slow kam | Ageing | Performance test |
Season calendar (short)
| Mahina | Kaam |
|---|---|
| March–April | Summer se pehle saaf; earthing |
| May–June | Daily monitor; fan saaf |
| July–August | Toofan ke baad check |
| Oct–Nov | Katai ke baad dhool |
| December | Saal bhar kWh compare |
Generation kam par bill zyada? Saving kyu nahi — raat ko grid par pump chal raha ho sakta hai jab tum sirf din ka kWh dekhte ho.
Disclaimer: Har khet par alag. State DISCOM rule badalte hain. Technical kaam empanelled vendor se karwao. Ask Kisan EPC company nahi hai.

अक्सर पूछे जाने वाले प्रश्न
Solar pump ya plant ki generation kam kyu ho rahi hai?
Top 7 reasons: panel par dhool, naya shade (ped/building), inverter fault ya galat mode, galat tilt/direction, grid curtailment, panel ageing, aur monitoring nahi karne se problem late pata chalti hai.
Dhule panel se kitna loss hota hai?
Rajasthan, Gujarat jaisi jagah 10–25% tak loss barish ke beech common hai. Katai ke baad 15–30% tak girti hai jab tak saaf na karo. Safe cleaning ke liye alag guide padho.
Kya DISCOM meri generation rok sakta hai?
Haan — curtailment tab hota hai jab grid export absorb nahi kar paati. Rajasthan jaisi jagah dopahar ko strong sun ke bhi export band ho sakta hai. Ye panel kharab nahi, grid issue hai.
Kya 5–10 saal baad panel kam dete hain?
Haan, slow degradation — saal mein lagbhag 0.5–0.8%. 10 saal baad 5–8% kam normal hai. Achanak 30–40% drop usually dhool, shade ya inverter hota hai.
Roz generation kaise track karein?
Inverter app ya vendor ka portal — daily kWh note karo, pichhle saal ke same month se compare karo. PM-KUSUM install par login maangna mat bhoolna.
