3 kW Solar ke Fayde — Payback, ROI aur 25 Saal ka Hisaab
3 kW par indicative monthly bachat ₹3,240, aur simple payback lagbhag 1.9 saal. Numbers ke saath, aur caveats ke saath.
Seedha jawab
3 kW se Durg-Bhilai mein lagbhag 450 units per month banti hain, jinki indicative value ₹3,240 hai. ₹1,08,000 ke support ke baad ₹75,000 ke net investment par simple payback lagbhag 1.9 saal ka banta hai. Savings ka figure tabhi poora milta hai jab aapka current bill itna ya usse zyada ho — solar utni hi bijli ki bachat karta hai jitni aap actually use karte hain, aur CSPDCL ke fixed charges solar ke baad bhi bill par aate rehte hain.
3 kW ka payback sabse tez kyun dikhta hai
3 kW par payback ka number aam taur par sabse acha dikhta hai, aur uski wajah simple hai: support yahan maximum percentage par hai. Lekin yeh number tabhi real hai jab aapka bill itna ho ki generation ka poora value use ho sake. Agar bill chhota hai aur generation zyada, to extra units export hoti hain aur unka adjustment alag hisaab se hota hai.
| Parameter | Estimate |
|---|---|
| Gross system cost | ₹1,83,000 |
| Combined government support | ₹1,08,000 |
| Net investment | ₹75,000 |
| Monthly generation | ~450 units |
| Indicative monthly bachat | ₹3,240 |
| Indicative annual bachat | ₹38,880 |
| Simple payback | ~1.9 saal |
Payback ka number kaise padhein
Yeh ‘simple payback’ hai — isme tariff ka future badhna, panel ka annual degradation, aur beech mein inverter replacement ka kharcha count nahi hota. Practical baat yeh hai ki teenon cheezein ek doosre ko kaafi had tak balance kar deti hain: tariff badhne se bachat badhti hai, degradation aur maintenance se thodi ghatti hai.
Paise ke alawa kya milta hai
- Bill ki predictability — garmi mein bill ka achanak double hona kam ho jaata hai
- Load shifting ki aadat — din mein washing machine aur pump chalane se self-consumption badhta hai
- 5475 units per saal ka clean generation, thermal grid par utna hi kam load
- Property par ek visible, long-life installation
ROI kis cheez se kharaab hota hai
- 1Over-sizing: zaroorat se bada system lagwana — extra units ka poora value nahi milta
- 2Shadow ignore karna: ek shaded string poore array ka output gira deti hai
- 3Cleaning na karna: Bhilai belt ki dhool ka asar seedha output par dikhta hai
- 4Net metering late karwana: jab tak bi-directional meter nahi lagta, export ka credit nahi milta
- 5Sasta structure ya cable: paanch saal baad ka repair poora payback kha jaata hai
3 kW ka loan aur uska sequence
3 kW par ek practical uljhan aati hai: loan sanction pehle hota hai aur support commissioning ke baad. Kuch lenders poore system cost par sanction karte hain aur support aane par aap prepay karte hain; kuch support minus wale amount par sanction karte hain. Pehle case mein aapko do-teen mahine zyada EMI dikhti hai, doosre mein sanction chhota rehta hai. Sanction letter par prepayment clause dhyan se padhiye — yahi baad mein farak banata hai.
Aksar poochhe jaane waale sawaal
- Payback ke baad bijli free ho jaati hai?
- Bill zero nahi hota — fixed charges aur raat ki consumption rehti hai. Lekin payback ke baad jo units aap generate karte hain, unka koi capital cost nahi bachta. Maintenance chhota lekin zero nahi hota.
- Property bechne par solar ka kya hota hai?
- Installation chhat ke saath jaata hai. Net metering connection naye consumer ke naam par transfer karwana padta hai — CSPDCL mein yeh ek standard process hai, lekin ise sale ke waqt list mein rakhiye.
- Kya yeh figures guarantee hain?
- Nahi, aur koi bhi vendor inki guarantee nahi de sakta. Yeh ek transparent model par bane estimates hain — 5 units/kW/day generation aur ₹8/unit ke blended tariff par. Aapka actual result chhat, shadow, usage pattern aur tariff slab par depend karega.
- 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.
