₹4,000 Bijli Bill ke liye Kitna Solar? — Durg-Bhilai Sizing Guide
₹4,000 monthly bill par aam taur par 3 kW system suggest hota hai — cost ₹1,83,000, support ke baad ₹75,000, aur expected bachat ka hisaab.
Seedha jawab
Agar aapka average monthly bill ₹4,000 ke aas-paas rehta hai, to Durg-Bhilai mein aam taur par 3 kW ka rooftop system suggest hota hai. Uska indicative gross cost ₹1,83,000 hai, aur ₹1,08,000 tak support ke baad net lagbhag ₹75,000. Expected monthly bachat lagbhag ₹3,240 — poora bill zero nahi hoga.
₹4,000 ka bill — ek AC wala ghar
Chaar hazaar ka bill aam taur par us ghar ka hota hai jahan ek AC regular chalta hai, geyser hai, aur pump bhi. Is band mein log sabse zyada confusion mein hote hain: 3 kW lein ya 4 kW. Farak yeh hai ki support dono par same rehta hai, lekin 4 kW par extra generation milti hai. Agar aapka AC din mein bhi chalta hai, to bada system apna paisa nikaal leta hai; agar sirf raat mein chalta hai, to chhota behtar hai.
Bill se capacity kaise nikalti hai
Hisaab do step ka hai. Pehle bill se units: ₹4,000 ÷ lagbhag ₹8 per unit ≈ 500 units per month. Phir units se capacity: Durg-Bhilai mein 1 kW se roughly 150 units per month expected hain, to 500 ÷ 150 ≈ 3.3 kW — jise practical whole-kW size par round kiya jaata hai.
| Parameter | Estimate |
|---|---|
| Approx monthly units | ~500 units |
| Suggested capacity | 3 kW |
| Panels (545 W class) | 6 |
| Shadow-free roof needed | ~300+ sq ft |
| Gross cost (indicative) | ₹1,83,000 |
| Combined support | ₹1,08,000 |
| Net investment | ₹75,000 |
| Expected monthly bachat | ₹3,240 |
Is band mein sabse badi galti
Is band mein sanctioned load ka check sabse zyada zaroori hai. Purane connections aksar 2 kW ya 3 kW sanctioned load par hote hain, aur CSPDCL usse zyada capacity sanction nahi karta — pehle enhancement ki application lagti hai.
Bill zero kyun nahi hota
Do wajah hain. Pehli: CSPDCL ke fixed aur minimum charges solar ke baad bhi lagte hain. Doosri: raat ki consumption grid se aati hai, aur net metering usme se export ki units adjust karti hai — lekin adjustment ka apna hisaab hota hai. Isliye hum bachat ko 90% realisation par cap karke dikhate hain, 100% par nahi.
Monsoon (July–September) mein generation girta hai aur March–May mein peak par hota hai. Annual average isi utaar-chadhav ko maan kar nikala jaata hai.
Aksar poochhe jaane waale sawaal
- Mera bill har mahine badalta rehta hai, kaunsa lein?
- Pichhle 12 mahine ka average sabse sahi hota hai. Agar 12 mahine ka data nahi hai, to ek garmi ka aur ek sardi ka bill le kar unka average nikaal lijiye — woh kaafi paas aa jaata hai.
- Kya 3 kW se mera bill aadha ho jayega?
- Is model par expected bachat ₹3,240 ke aas-paas hai. Actual figure aapke usage pattern par depend karega — jitna zyada consumption din ke waqt hoga, utna behtar result milega.
- 3 kW ke baad subsidy kyun nahi badhti?
- PM Surya Ghar ka central support 3 kW slab par cap hai — yeh scheme ka design hai. Isliye bade system par support ka percentage ghatta jaata hai, absolute figure wahi rehta hai.
- Mera sanctioned load 2 kW hai, 3 kW lag sakta hai?
- Pehle sanctioned load enhancement ki application deni hogi. Yeh step shuru mein karna chahiye — baad mein pata chalne par poora process peeche khisak jaata hai.
