5 kW Solar ke liye Kitni Chhat Chahiye? — Area, Layout aur Shadow
5 kW ke liye lagbhag 500 sq ft shadow-free chhat, ya elevated structure par 350 sq ft usable. Layout, tilt aur access ki practical baatein.
Seedha jawab
5 kW ke liye aam taur par lagbhag 500 sq ft shadow-free chhat chahiye hoti hai — yaani 10 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 350 sq ft usable roof tak aa jaati hai.
5 kW ke liye terrace ki requirement
5 kW ke liye lagbhag paanch sau square feet shadow-free chhat chahiye hoti hai, ya elevated structure par kareeb saadhe teen sau square feet usable. Is size par terrace ka poora naksha design mein aata hai: das modules ki rows, unke beech spacing, chaaron taraf cleaning walkway, aur cable route. Aksar yeh size uss point par pahunchta hai jahan ghar ki chhat par doosri cheezon — tanki, kapde sukhane ki jagah — ke saath negotiation karni padti hai.
| Structure type | Approx roof area | Kab chunte hain |
|---|---|---|
| Standard (low-height) | ~500 sq ft | Khali terrace, jahan neeche jagah use nahi karni |
| Elevated / raised | ~350 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 5 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.
10 panels ka layout
545 W class ke ek module ka footprint lagbhag 2.3 m × 1.1 m hota hai. 10 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.
5 kW — sabse zyada lagne wala residential size
5 kW is region ka sabse zyada lagne wala residential size hai — 3 BHK ghar, do AC, fridge, geyser, washing machine aur pump. Yeh wahi capacity hai jispar hamara confirmed reference price bana hai, isliye 5 kW ka figure is poori website par sabse bharosemand number hai; baaki sab capacities usi rate se nikali gayi hain. Agar aapka garmi ka bill paanch-saat hazaar ke beech rehta hai, to aapki shortlist 5 kW se shuru hoti 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.
- 5 kW ka price confirmed kyun hai aur baaki ka nahi?
- 5 kW hamara business-confirmed reference configuration hai. Baaki capacities uske per-kW rate se nikali gayi hain, isliye unhe hum indicative kehte hain — final figure survey ke baad quotation mein aata hai.
- 5 kW par single-phase chalega ya three-phase chahiye?
- 5 kW tak aam taur par single-phase chal jaata hai. Yeh aapke existing connection aur CSPDCL ki sanction par depend karta hai — survey mein hum aapka bill dekh kar confirm karte hain.
