QUOTATION
Size chunein, quotation saamne. Inverter aur battery apni marzi ki, aur har cheez ki tafseel — kya shamil hai aur kya nahi. Koi advance nahi, koi phone call zaroori nahi.
Upar wala total chaar hisson mein hai. Itemised quotation mein har cheez alag likhi hoti hai — panel, structure, cable ka har meter, DB box, installation. Jo cheez nikalwani ho wo nikalwa sakte hain.

Sach ye hai ke bina chhat dekhe koi exact number nahi de sakta — aur jo deta hai, wo baad mein adjust karta hai. Lekin approximate range nikalna mushkil nahi, kyunke system ka kharcha chaar cheezon se banta hai: panels aur structure, wiring, inverter aur battery, aur installation. Upar wala calculator yehi chaar hisse jorta hai, aaj ke rates par.
Apne pichle barah mahine ka sab se bara bill dekhein, average nahi. Solar us sab se bare mahine ke hisab se lagana chahiye, warna garmi mein system kam par jata hai. Karachi ke aam ghar mein jahan do AC chalte hain, 6 kW sab se zyada lagta hai. Bill 90,000 se upar jata ho to 10 kW dekhna chahiye.
Inverter ki qeemat tay hai, lekin battery par kharcha aap ke raat ke load par depend karta hai. Sirf fans, lights aur fridge chalane hain to 5 kWh kaafi hai. Raat bhar AC chalana ho to 10 kWh se upar jana parta hai. Aur nameplate capacity aur usable capacity alag cheezein hain — quotation lete waqt usable poochein, sab se.
Earthing zameen ke hisab se hoti hai — kahin chaar foot par earth mil jati hai, kahin bees foot khodna parta hai. Net metering ki application aur fees, civil work, chhat ki repair aur waterproofing bhi alag line par aate hain. Jo company ye sab “included” likh deti hai, wo ya to ye kaam theek se karti nahi, ya baad mein extra bill bhejti hai.
Nahi. Ye approximate hai. Final price site survey ke baad tay hoti hai — chhat ki halat, cable ki lambai, aur aap ka asal load dekh kar. Survey free hai aur koi advance nahi lagta.
Nahi. Survey bhi free hai aur quotation bhi. Paisa order confirm karne par shuru hota hai — 50% order par, 30% material site par pahunchne par, aur 20% commissioning ke baad.
645W ke LONGi Himo X10 panel ho to 10 panel. Final number chhat ki jagah aur aap ke load par depend karta hai.
Paisa wapas. Cable, structure aur accessories kaam ke baad aap ke saamne naape jate hain. Jo mal bach gaya wo aap ka hai — bill mein se kam ho jata hai.
DC cable chhat par lagti hai aur saal bhar dhoop mein rehti hai. Aam cable ka PVC waqt ke saath bhurbhura ho jata hai, aur kahin short ho to aag cable ke saath phailti hai. Fire-proof cable jalti nahi. Poore system par farq 3% ke qareeb aata hai.
Haan. Survey se commissioning tak aik hi team. Warranty claim bhi hum file karte hain — aap ko supplier ke peeche nahi bhagna parta.
