Solar DC cable — Kaam, Installation aur Cost
Solar DC cable rooftop solar mein kya karta hai, kaise install hota hai, cost kis par depend karta hai, aur quotation mein ise kaise verify karein.
Seedha jawab
Solar DC cable — Panels se inverter tak jaane wala UV-resistant, DC-rated cable. Patla ya galat cable resistance loss create karta hai — yaani aapki banayi hui bijli cable mein hi garmi ban kar chali jaati hai. Yeh loss har din hota hai, 25 saal tak.
Isse halke mein lene par kya hota hai
Normal house wire ko DC side par use karna sabse common shortcut hai. Woh UV aur DC arc ke liye designed hi nahi hota, aur chhat par dhoop mein uska insulation kuch saalon mein crack karta hai.
Sabse common galti normal house wire ko DC side par use karna hai. Doosri galti cable ko conduit ya tray ke bina khula chhat par chhod dena — UV, garmi aur chuhe, teenon uske dushman hain. Teesri: MC4 connectors ko theek se crimp na karna, jisse resistance badhta hai aur connector garam hota hai.
Standards aur specification
DC cable par do numbers maayne rakhte hain: cross-section (sq mm) aur run length. Lamba run patle cable ke saath voltage drop badhata hai, aur woh drop har dhoop wale din, 25 saal tak, aapki generation se kata jaata hai. Solar-grade cable UV aur DC dono ke liye rated hota hai — normal house wire chhat ki dhoop mein kuch hi saalon mein crack karta hai.
Installation kaise hoti hai
Solar-grade twin-core DC cable, proper conduit ya cable tray mein, MC4 connectors ke saath — aur cable run jitna chhota ho sake, utna behtar.
- 1Survey ke waqt location aur routing decide hoti hai
- 2Design document mein rating aur specification likhi jaati hai
- 3Material delivery par make/model verify kijiye
- 4Solar DC cable install hota hai, baaki system ke saath coordinate karke
- 5Testing aur measured values ke saath handover report
Verify karne layak cheezein
- Cable solar-grade (UV aur DC rated) hai ya normal wire
- Cross-section (sq mm) current aur run length ke hisaab se
- Conduit/tray mein routed hai ya khula chhat par pada hai
- MC4 connectors branded hain aur properly crimped hain
Cost kis cheez par depend karta hai
Solar DC cable ka koi ek fixed rate nahi hota — woh rating, material quality aur installation scope par badalta hai. Isiliye hum yahan ek number nahi chhapte; upar di gayi checklist hi woh drivers hai jinse aapke quote ka figure bana hai. Website par fixed component price chhapna aapko galat expectation deta hai, kyunki yeh pricing batch aur availability ke saath badalti rehti hai.
- 1Component ka naam, make aur rating quotation par likha ho
- 2Quantity aur (jahan lagu ho) length ya size
- 3Included hai ya extra — saaf likha hua
- 4Warranty period alag se

Aksar poochhe jaane waale sawaal
- Kya Solar DC cable optional hai?
- Nahi. Yeh safety aur compliance ka hissa hai. Iske bina lagaya gaya system inspection mein bhi problem karta hai aur lambe samay mein bhi.
- Do quotes ka farak is component se aa raha hai?
- Ho sakta hai. Bada farak aam taur par capacity, structure aur panel model se aata hai — lekin balance-of-system components ko scope se nikal dena bhi ek common tareeka hai quote ko kam dikhane ka.
- Baad mein add karwa sakte hain?
- Technically haan, lekin baad mein karwana hamesha mehenga aur adhoora hota hai. Installation ke waqt karna hi sahi aur sasta raasta hai.
