6 kW Solar ke liye Kitni Chhat Chahiye? — Area, Layout aur Shadow
6 kW ke liye lagbhag 600 sq ft shadow-free chhat, ya elevated structure par 420 sq ft usable. Layout, tilt aur access ki practical baatein.
Seedha jawab
6 kW ke liye aam taur par lagbhag 600 sq ft shadow-free chhat chahiye hoti hai — yaani 12 modules ke liye roughly 100 sq ft per kW. Agar elevated structure use karein (jiske neeche aap chal-phir sakein), to effective requirement ghat kar lagbhag 420 sq ft usable roof tak aa jaati hai.
6 kW ke liye chhat ka poora naksha
6 kW par barah modules lagte hain aur chhat ka bada hissa cover ho jaata hai. Yahan layout ki sabse badi chunauti maintenance access hoti hai: agar aap panels ko deewar se deewar tak bichha denge, to cleaning ke liye chalne ki jagah nahi bachegi — aur is belt mein cleaning har dus-pandrah din chahiye. Design mein walkway ko jagah dena is size par koi luxury nahi, zaroorat hai.
| Structure type | Approx roof area | Kab chunte hain |
|---|---|---|
| Standard (low-height) | ~600 sq ft | Khali terrace, jahan neeche jagah use nahi karni |
| Elevated / raised | ~420 sq ft usable | Jahan tanki, seedhi ya parapet hai, ya neeche ki jagah bhi chahiye |
Area ka matlab sirf square feet nahi hota
Ek 1,200 sq ft chhat par bhi 6 kW nahi lag paata agar uska bada hissa subah ya shaam shadow mein rehta hai. Jo cheez maayne rakhti hai woh hai ‘shadow-free between 9 AM and 4 PM’. Paani ki tanki, staircase mumty, paros ki deewar, mobile tower aur ped — inki shadow din bhar chalti rehti hai, aur ek panel par partial shadow poore string ka output gira deti 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.
12 panels ka layout
545 W class ke ek module ka footprint lagbhag 2.3 m × 1.1 m hota hai. 12 modules ko rows mein lagaya jaata hai, aur har row ke beech itni jagah chhodni padti hai ki aage wali row ki shadow peechhe wali par na pade (inter-row spacing). Isiliye actual paper area se zyada roof lagta hai — yahi wajah hai ki simple ‘panel ka size × quantity’ calculation kam nikalta hai.
- Rows ke beech shadow-clearance spacing
- Panels ke chaaron taraf maintenance walkway — cleaning ke liye
- Inverter ke liye shaded wall space, panels ke paas
- Cable route ka path panels se inverter aur meter tak
Structure aur roof ki condition
RCC chhat par ballast ya chemical anchoring dono chalte hain. Tin ya asbestos shed par mounting alag hoti hai aur wind-load calculation zyada important ho jaata hai. Agar chhat par pehle se waterproofing hai, to anchoring ke baad us area ki sealing dubara karwana zaroori hai — yeh aksar quotation se chhoot jaata hai.
6 kW kis ghar ka size hai
6 kW un gharon mein lagta hai jahan garmi ka bill saat hazaar se upar chala jaata hai — do se teen AC, do fridge, geyser aur pump. Durg-Bhilai mein yeh aksar bade independent ghar ya joint family ka size hota hai. Is capacity par ek naya factor aata hai: CSPDCL three-phase connection maangta hai, aur agar aapka ghar abhi single-phase par hai to woh conversion poore project ka ek alag step ban jaata hai — technically routine, lekin timeline mein jodna padta hai.
Aksar poochhe jaane waale sawaal
- Chhat par pehle se paani ki tanki hai, problem hogi?
- Tanki khud problem nahi hai — uski shadow hai. Survey mein hum din ke teen alag time par shadow plot karte hain. Aksar solution yeh nikalta hai ki tanki ke aas-paas layout adjust ho jaye, ya structure uthaya jaye.
- Kya panels ke neeche ki jagah use kar sakte hain?
- Elevated structure ke saath haan — log uske neeche kapde sukhate hain, chhota storage rakhte hain, ya bas chalne ki jagah rakhte hain. Standard low structure ke neeche sirf maintenance crawl space hoti hai.
- Kiraye ke ghar par lag sakta hai?
- Technically haan, lekin subsidy ke liye roof par ownership ya society/owner ki likhit permission chahiye hoti hai, aur net metering CSPDCL connection holder ke naam par hi hota hai.
- 6 kW ke liye three-phase zaroori hai?
- Aam taur par haan. 5 kW se upar CSPDCL three-phase sanction maangta hai. Agar aapka ghar single-phase par hai, to conversion ki application project ka hissa ban jaati hai.
- 6 kW par subsidy 5 kW se zyada milegi?
- Nahi. Support 3 kW ke slab par cap ho chuka hota hai — 5 kW aur 6 kW dono par wahi amount milta hai.
