Dekho, on-grid solar lagwa diya, paisa diya, par light / bill se matlab waisa nahi jaisa socha tha — ye bahut common hai gaon mein. Kabhi system sahi design par chal raha hota hai, par WhatsApp wali baat galat thi.
Is article mein asli reasons: net metering vs export-only wiring, cut par inverter band, meter/CT galat, DISCOM activation pending. Naya install June 2026: ALMM impact. Farm scheme: PM-KUSUM.
On-grid solar diesel gen set nahi hai. Grid cut par inverter band — safety (lineman ko shock na lage). Dhoop mein panel hai par ghar ki light nahi jab tak grid na aaye — hybrid + battery ya off-grid line chahiye backup ke liye.
Problem 1: Cut par light nahi
Kya hota hai
DISCOM line gayi → inverter ko stable grid nahi milta → convert band.
Kisan kya sochta hai
“Suraj hai, fan chalna chahiye.”
Ilaj
| Option | Baat |
|---|---|
| Grid ka wait | Free backup nahi |
| Hybrid + battery | Cut mein light — mehnga |
| Critical load circuit | Fan, light, mobile |
| Off-grid pump alag | Component B jaisa |
Padho: power cut par hybrid
Problem 2: Grid hai par bill same
Net metering activate nahi
Panel lage, bi-directional meter / agreement pending — solar alag, ghar import par.
Check: DISCOM letter, meter serial, app par import/export.
Gross metering shock
Naye rooftop par gross — solar sasti rate, khareedna full retail. Bill kam feel nahi hota.
Check: sanction letter — installer brochure nahi.
Export-only / galat wiring
Solar AC sirf grid side → load import path par → bill poora, solar export kare.
Fix: Electrician single-line diagram vs DISCOM standard — load bus coupling / CT direction.
Problem 3: Inverter off / trip
- AC/DC switch band service ke baad
- Voltage high/low rural feeder par
- Frequency trip — pump inverter trip
Display ka error code photo lo — brand service call karo.
Problem 4: Raat ko solar kaam nahi karta
Bina battery raat ka load grid par hi rahega — tubewell night par bill mein dikhega. Solar = din ka offset + net credit (policy par).
Diagnosis — 6 step
- Cut hai? → on-grid band = normal
- Net meter live? App par import/export
- Net ya gross — paper par
- Wiring diagram — sanction match?
- Din test — load kam karke import dekho
- Activation dispute — panels theek, meter pending
Hybrid kab lein?
Lein agar roz 2–4+ hour cut, doodh machine, drip control zaroori.
Na lein agar grid stable, sirf bill save, cut mein backup chahiye hi nahi.
Compare: on-grid vs hybrid pump
DISCOM bill dispute
Export dikhe par credit na ho — 6 mahine reading save karo. Rajasthan: net metering dispute.
June 2026 install? ALMM listed hardware — kisan ALMM guide. Sinchai ke liye pump alag plan — bill kitna kam.
Bottom line
- Cut = light nahi → on-grid normal; backup = hybrid/battery
- Bill same → net metering, gross/net type, wiring check
- Diagram + DISCOM app — bina proof ladai mat karo

अक्सर पूछे जाने वाले प्रश्न
Bijli cut par on-grid solar ghar ki light kyu nahi chalata?
Grid-tied inverter safety ke liye grid fail hote hi band ho jata hai (anti-islanding). Panel dhoop mein bhi ghar ko power nahi denge jab tak grid wapas na aaye — jab tak hybrid + battery ya alag off-grid circuit na ho.
Solar laga hai par bill kam kyu nahi hota?
Aksar: export-only wiring, galat CT/meter, net metering activate nahi, ya gross metering approval. Installer se single-line diagram lo aur DISCOM app par import/export dekho.
Net metering aur gross metering mein farq?
Net metering mein export import se adjust hota hai. Gross mein solar alag sasti rate par bikti hai, ghar ki bijli full rate par — bill kam nahi dikhega. Sanction letter par type dekho.
Galat wiring se solar ghar use hi na ho?
Haan — agar solar sirf grid side par laga aur load alag path par, to ghar 100% grid se lega aur solar export karega. Licensed electrician DISCOM standard se match kare.
Hybrid kab lena chahiye?
Roz cut lagte hain aur light/fan/pump control chahiye to hybrid + battery socho. [on-grid vs hybrid pump](/blog/on-grid-vs-hybrid-solar-pump-2026), [power cut hybrid](/blog/on-grid-power-cut-hybrid-better) padho.
