Rooftop Solar in Durg & Bhilai — Poora Guide, Shuru se Aakhir tak
Durg-Bhilai mein rooftop solar lagwane ka poora picture — sizing, ₹3,05,000 ka 5 kW reference, ₹1,08,000 tak support, CSPDCL net metering aur timeline.
Seedha jawab
Durg-Bhilai mein rooftop solar ka poora rasta chaar steps ka hai: bill se capacity nikalna, chhat ka shadow-free area check karna, PM Surya Ghar portal par apply karna, aur CSPDCL se net meter lagwana. Ek typical 3–4 BHK ghar ke liye 5 kW system ka indicative cost ₹3,05,000 hai, aur ₹1,08,000 tak support ke baad net lagbhag ₹1,97,000.
Step 1 — Bill se capacity
Hisaab seedha hai: apne bill ko lagbhag ₹8 per unit se divide kijiye (units nikal aayenge), aur phir 150 se divide kijiye — kyunki Durg-Bhilai mein 1 kW se roughly 150 units per month expected hain. ₹5,000 ke bill par yeh lagbhag 4 kW banta hai. Ek mahine ka nahi, saal ka average bill lijiye — yahan garmi aur sardi ke bill mein bada farak hota hai.
| Capacity | Gross cost | Net after support | Roof needed | Units/month |
|---|---|---|---|---|
| 3 kW | ₹1,83,000 | ₹75,000 | ~300 sq ft | ~450 |
| 5 kW | ₹3,05,000 | ₹1,97,000 | ~500 sq ft | ~750 |
| 10 kW | ₹6,10,000 | ₹5,02,000 | ~1000 sq ft | ~1500 |
Step 2 — Chhat ka assessment
Roof area ka number akela kaafi nahi hai — woh area 9 AM se 4 PM ke beech shadow-free hona chahiye. Paani ki tanki, mumty, paros ki deewar aur ped, sab din bhar shadow move karte hain. Survey mein shadow din ke teen alag time par check hona chahiye, ek baar nahi.
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.
Step 3 — Subsidy aur approval
- 1PM Surya Ghar portal par CSPDCL consumer number se registration
- 2CSPDCL ki technical feasibility approval
- 3Sanctioned load system capacity se kam ho to enhancement application
- 4Registered vendor se installation, ALMM-listed DCR panels ke saath
- 5CSPDCL inspection aur bi-directional net meter
- 6Commissioning certificate, phir DBT se subsidy bank account mein
Step 4 — Kitna time lagta hai
Physical installation aam taur par kuch dinon ka kaam hai. Lambi wait approvals ki hoti hai — feasibility shuru mein, aur CSPDCL inspection + net meter aakhir mein. Realistic expectation: poora cycle survey se commissioning tak kuch hafton ka. Net meter lagne tak aapki export ki units ka record nahi banta, isliye us step par follow-up sabse zaroori hai.
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.
Aksar poochhe jaane waale sawaal
- Sabse pehla kaam kya karna chahiye?
- Apna pichhla bill nikaliye aur uspar sanctioned load dekhiye. Yeh do numbers — average bill aur sanctioned load — 90% sizing ka kaam kar dete hain.
- Kya poora bill khatam ho jayega?
- Nahi. CSPDCL ke fixed aur minimum charges solar ke baad bhi lagte hain. Bill bahut kam ho sakta hai, zero nahi — aur jo vendor zero bill bole, us par sawaal kijiye.
- Kiraye ke ghar par lag sakta hai?
- Technically haan, lekin subsidy ke liye roof par ownership ya owner/society ki likhit permission chahiye, aur net metering connection holder ke naam par hota hai.
