2 kW Solar ke liye Kitne Panels? — Module Selection Guide
2 kW ke liye lagbhag 4 modules (545 W class). DCR vs non-DCR, ALMM listing, warranty aur Durg-Bhilai mein availability.
Seedha jawab
2 kW ke liye 545 W class ke lagbhag 4 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.
Char modules, ek string
Chaar modules ek hi string par aate hain aur ek MPPT kaafi hota hai, badi ki chhat single direction mein ho. Agar aapki chhat do hisson mein bat gayi hai — thoda east, thoda south — to do chhoti strings aur do MPPT behtar rehte hain. Yeh decision survey mein hi hota hai; baad mein inverter badalna padta hai.
| Module rating | Approx panels | Note |
|---|---|---|
| 450 W | 5 | Purani generation, ab kam quote hoti hai |
| 545 W | 4 | Aaj ka common residential choice |
| 585 W | 4 | 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.
2 kW ka slab — support dogunaa ho jaata hai
2 kW woh jagah hai jahan scheme ka structure aapke haq mein kaam karta hai: central support 60,000 aur state 30,000 — 1 kW ke muqable support theek dogunaa, jabki system cost bhi lagbhag dogunaa hi hai. Iska matlab hai ki support ka percentage 1 kW jaisa hi strong rehta hai, lekin aapko dugni generation milti hai. Agar aap 1 kW aur 2 kW ke beech soch rahe hain, to yeh comparison decisive hota 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. 2 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.
- 2 kW se AC chalega?
- Din ke waqt ek chhota AC kuch der chal sakta hai, lekin baaki load ke saath nahi. Agar AC regular chalana hai to sizing us load ko maan kar honi chahiye — warna aap grid se hi kheenchte rahenge.
- 1 kW aur 2 kW mein kaun sa behtar hai?
- Support 1 kW se 2 kW par theek dogunaa ho jaata hai jabki cost bhi lagbhag dugni hi hoti hai. Isliye agar chhat aur bill dono allow karte hain, to 2 kW aam taur par behtar sauda nikalta hai.
