3 kW Solar ke liye Kitne Panels? — Module Selection Guide
3 kW ke liye lagbhag 6 modules (545 W class). DCR vs non-DCR, ALMM listing, warranty aur Durg-Bhilai mein availability.
Seedha jawab
3 kW ke liye 545 W class ke lagbhag 6 modules lagte hain. Agar higher-wattage module (jaise 575–600 W) use ho, to count thoda kam ho jaata hai lekin kW same rehta hai — aur kW hi woh number hai jispar subsidy, net metering aur generation depend karte hain.
Chhah modules aur DCR ka sawaal
Chhah modules, ek string, ek MPPT — design simple rehta hai. Is size par DCR ka sawaal sabse important ho jaata hai, kyunki support ka amount ab bada hai aur non-DCR panel lagne par poora 1,08,000 haath se nikal jaata hai. Delivery ke din module ka model number aur serial invoice se match karna is size par sabse zyada paisa bachata hai.
| Module rating | Approx panels | Note |
|---|---|---|
| 450 W | 7 | Purani generation, ab kam quote hoti hai |
| 545 W | 6 | Aaj ka common residential choice |
| 585 W | 6 | Kam jagah mein zyada kW — thoda premium |
DCR ya non-DCR — yeh decision subsidy tay karta hai
DCR (Domestic Content Requirement) module ka matlab hai cell aur module dono India mein bane hain. PM Surya Ghar ki subsidy claim karne ke liye DCR panel compulsory hai. Non-DCR panel aksar sasta milta hai, aur kuch vendors bina bataye wahi laga dete hain — aur subsidy application reject ho jaati hai. Delivery ke waqt module ka serial number aur ALMM listing khud check kijiye.
Module technology — mono PERC aur TOPCon
Aaj residential rooftop par mono PERC aur TOPCon dono aate hain. TOPCon ka temperature coefficient behtar hota hai, jo Durg-Bhilai ki 45°C wali garmi mein practical farak deta hai. Bifacial modules elevated structure par thoda extra dete hain, lekin low-height structure par unka rear-side gain minimal rehta hai — isliye har chhat par bifacial ka premium justify nahi hota.
- ALMM list par module ka model number verify kijiye
- Product warranty (manufacturing defects) aur performance warranty (output) alag-alag hoti hain
- Standard performance warranty lagbhag 25 saal, ek declared annual degradation ke saath
- Warranty manufacturer ki hoti hai — installer ki nahi. Delivery challan aur invoice sambhal kar rakhiye
Durg-Bhilai mein availability
Hum ALMM-listed modules quote karte hain aur aapko delivery se pehle exact make aur model likhit mein dete hain. Kaunsa brand available hoga, yeh us waqt ke stock aur aapki DCR requirement par depend karta hai — isliye hum pehle se kisi ek brand ka vaada nahi karte, balki specification aur listing status par commit karte hain.
3 kW par support apne peak par pahunch jaata hai
3 kW aur usse upar, central support 78,000 par cap ho jaata hai aur Chhattisgarh ka hissa 30,000 — kul 1,08,000. 4 kW, 6 kW ya 10 kW, teenon par yahi figure rehta hai. Isliye percentage ke hisaab se 3 kW sabse aage nikalta hai. Faisla karte waqt yeh dekhna chahiye ki aapko zyada generation chahiye ya zyada support-percentage — dono ek saath nahi milte, aur yahi is size ka core trade-off hai.
Aksar poochhe jaane waale sawaal
- Kam panel lagwa kar paisa bacha sakte hain?
- Kam panel ka matlab kam kW, aur kam kW ka matlab kam generation. 3 kW ka case aapke load par bana hai — usse ghatane par bill utna kam nahi hoga jitna aap expect kar rahe hain.
- Alag-alag brand ke panel mix kar sakte hain?
- Ek hi string mein mix karna galat practice hai — electrical mismatch se poore string ka output girta hai. Agar zaroori ho to alag MPPT par alag string rakhi jaati hai, aur yeh design mein pehle se likha hona chahiye.
- Panel kitne saal chalta hai?
- Performance warranty aam taur par 25 saal ki hoti hai, jismein har saal ek declared degradation allowed hota hai. Panel achanak band nahi hota — uska output dheere-dheere ghatta hai.
- 3 kW ke baad subsidy kyun nahi badhti?
- PM Surya Ghar ka central support 3 kW slab par cap hai — yeh scheme ka design hai. Isliye bade system par support ka percentage ghatta jaata hai, absolute figure wahi rehta hai.
- Mera sanctioned load 2 kW hai, 3 kW lag sakta hai?
- Pehle sanctioned load enhancement ki application deni hogi. Yeh step shuru mein karna chahiye — baad mein pata chalne par poora process peeche khisak jaata hai.
