8 kW Solar Kitni Units Banata Hai? — Durg-Bhilai ka Realistic Output
8 kW se Durg-Bhilai mein lagbhag 1200 units per month aur 14600 units saal bhar mein. Season-wise breakup aur output girne ki wajahein.
Seedha jawab
Durg-Bhilai region mein ek 8 kW rooftop system se roughly 40 units per day, 1200 units per month, aur 14600 units per saal ki expectation rakhi jaati hai. Yeh annual average hai — kisi ek din ka figure isse kaafi upar ya neeche ja sakta hai.
8 kW par phase imbalance ka sawaal
Is scale par sabse zyada dikhne wali technical galti phase imbalance hoti hai. Three-phase connection par agar ghar ka load ek phase par jhuka hua hai aur solar teenon par barabar de raha hai, to meter par hisaab waisa nahi baithta jaisa aap expect karte hain. Commissioning ke waqt phase-wise load reading maangiye — yeh ek baar ka kaam hai aur baad mein mahinon ki confusion bacha deta hai.
| Season | Monthly units (approx) | Kya hota hai |
|---|---|---|
| March–May (peak) | ~1380 | Lambe din, saaf aasman — saal ka best output |
| June | ~1200 | Pre-monsoon, mixed |
| July–September (monsoon) | ~780 | Badal aur barish — sabse kam output |
| October–February | ~1140 | Thandi hawa panels ke liye achhi, din chhote |
Yeh number kahan se aata hai
Hum 5 units per kW per day ka assumption lete hain, jo central India ke liye conservative side par hai. Isliye 8 kW × 5 = 40 units per day. Kuch vendors 5.5 ya 6 units per kW quote karte hain — woh theoretical best-case hota hai, jismein dhool, temperature loss aur inverter efficiency count nahi hoti.
Output kyun girta hai — Durg-Bhilai specific
Durg aur Bhilai ki chhaton par do cheezein sabse zyada output kharaab karti hain — Bhilai Steel Plant belt ki industrial dhool, aur paani ki tanki ya mobile tower ki shadow.
- Dhool ki parat: Bhilai belt mein 10–15 din mein ek baar cleaning na ho to output 8–15% tak gir sakta hai
- Shadow: subah 9 se shaam 4 ke beech ek bhi panel par partial shadow poore string ka output kam karta hai
- Temperature: 45°C+ garmi mein panel ki efficiency rated value se kam ho jaati hai — isiliye May ka output April se hamesha zyada nahi hota
- Orientation: south-facing chhat par lagbhag 20°–21° tilt Durg latitude ke liye best average deta hai
- Inverter clipping: agar inverter system se chhota hai, to peak hours mein generation kat jaata hai
Durg district lagbhag 21.2°N par hai, isliye panels south-facing aur roughly 20°–21° tilt par lagte hain — yahi saal bhar ka best average deta hai.
Generation se bill par kya asar
1200 units per month ki value lagbhag ₹8,640 banti 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. Net metering ke through jo units aap din mein use nahi karte, woh grid mein jaati hain aur aapke bill se adjust hoti hain.
8 kW ka return din ke pattern par tika hai
Aath kilowatt ka return ek hi cheez par tika hai: din ke waqt ka consumption. Jis ghar mein din bhar koi nahi hota, wahan itna bada array apni aadhi generation export kar deta hai, aur export ki unit self-consumed unit jitni valuable nahi hoti. Isliye is size ka faisla bill ke figure se zyada aapke ghar ke daily pattern se hona chahiye — kaun ghar par hai, kab, aur kya chal raha hai.
Aksar poochhe jaane waale sawaal
- Barish mein generation bilkul band ho jaata hai?
- Nahi. Badal wale din output kaafi kam hota hai — kabhi normal ka 20–30% — lekin zero nahi hota. Barish ka ek fayda bhi hai: woh panels se dhool dho deti hai.
- Generation kaise check karein?
- Inverter ka display ya uska mobile app daily aur cumulative units dikhata hai. Installation ke waqt monitoring set-up karwa lena zaroori hai — warna aapko pata hi nahi chalega ki output gir raha hai.
- 8 kW se mera poora bill khatam ho jayega?
- Poora nahi. CSPDCL ke fixed aur minimum charges solar ke baad bhi lagte hain, aur raat ki consumption grid se hi aati hai. Bill bahut kam ho sakta hai, zero nahi — jo vendor zero bill bole, us par sawaal kijiye.
- 6 kW se 8 kW par jaana kab sahi hai?
- Tab, jab aapka din ka load 6 kW ko regularly saturate kar raha ho — na ki tab jab bill bada dikhe. Bade bill ki wajah raat ki khapat bhi ho sakti hai, aur uska ilaaj bada array nahi hai.
- Is size par AMC lena chahiye?
- Aam taur par haan, agar chhat tak aapki pahunch aasan nahi hai. Solah modules ki cleaning aur saal mein ek electrical inspection — dono ke liye AMC ka scope aur visit count likhit mein dekh lijiye.
