1 kW Solar ke Fayde — Payback, ROI aur 25 Saal ka Hisaab
1 kW par indicative monthly bachat ₹1,080, aur simple payback lagbhag 1.2 saal. Numbers ke saath, aur caveats ke saath.
Seedha jawab
1 kW se Durg-Bhilai mein lagbhag 150 units per month banti hain, jinki indicative value ₹1,080 hai. ₹45,000 ke support ke baad ₹16,000 ke net investment par simple payback lagbhag 1.2 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.
1 kW ka return kaisa dikhta hai
1 kW ka absolute paisa chhota hai — bachat bhi chhoti, investment bhi chhota. Iska return isliye interesting hota hai kyunki support ka percentage yahan sabse zyada hai. Lekin ek practical baat: agar aapka bill pehle se hi kam hai, to bachat ka figure aapke bill se cap ho jaayega, aur payback lamba dikhega. 1 kW un logon ke liye behtar kaam karta hai jinka bill madhyam hai aur jo aage capacity badhane ka plan rakhte hain.
| Parameter | Estimate |
|---|---|
| Gross system cost | ₹61,000 |
| Combined government support | ₹45,000 |
| Net investment | ₹16,000 |
| Monthly generation | ~150 units |
| Indicative monthly bachat | ₹1,080 |
| Indicative annual bachat | ₹12,960 |
| Simple payback | ~1.2 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
- 1825 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
1 kW par finance karna samajh mein aata hai?
Itni chhoti amount par loan ka processing effort aur uska interest aksar justify nahi hota — bahut se log 1 kW cash mein hi kar lete hain, ya usme ghar ka chhota saving lagate hain. Agar finance karna hi hai, to dekhiye ki lender ka minimum ticket size kya hai; kai lenders is amount se neeche solar loan dete hi nahi. Aur processing fee flat hoti hai, to chhote principal par woh percentage mein bhaari padti 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.
- 1 kW se kitne appliance chalenge?
- Din ke waqt lights, fans, ek fridge aur TV ke aas-paas ka load. AC, geyser ya pump ke liye yeh capacity nahi hai — woh grid se hi chalenge.
- Baad mein 1 kW se badha sakte hain?
- Haan, lekin inverter ki rating aur CSPDCL ka sanction dono revise karne padte hain. Agar aapko lagta hai ki aage badhana hai, to abhi inverter mein thoda headroom rakhwa lijiye — baad mein poora inverter badalne se sasta padta hai.
