Apni bijli ki zaroorat likhein — tool batayega kitne kW ka solar system chahiye, kitna kharcha aayega, aur paisay kitne arse me wapas honge.
Built on Pakistan's 2026 net-billing rules: power you use yourself is worth your full per-unit rate; surplus exported to the grid is paid only about Rs 10–11 per unit.
Export rate 2026: Rs 10–11 / unit
Top home slab: ~Rs 47.20 / unit
5 kW system: Rs 6.2–7.6 lakh
5 kW generation: ~540 units / month

Do tareeqay hain — appliances wala tareeqa zyada sahi size deta hai, kyunke wo aap ke asal load par chalta hai.

Watt har appliance ke aam (typical) hain — aap ke model ke hisaab se badal sakte hain. Fridge din bhar on rehta hai lekin compressor ruk ruk kar chalta hai, is liye us ke effective ghantay 12 rakhe hain.
Aam ghar: 3–5 kW · AC zyada ho to 7–10 kW · bara ghar / dukaan: 10–20 kW

Yehi sab se ahem number hai. 2026 net billing me export sirf Rs 10–11/unit milta hai, is liye jo bijli din me khud istemal ho — washing machine, motor, AC din me chalana — wahi asal bachat hai. Din me ghar khaali rehta ho to 40–50% rakhein; din bhar load chalta ho to 75–85%.

حساب کیسے لگتا ہےHow It Works
Daily units = Σ (watts × adad × ghantay) ÷ 1000 · Size (kW) = daily units ÷ (sun hours × (1 − losses))
- Size ka hisaab: aap ke appliances ki rozana zaroorat (units) ko 4.5 peak sun hours aur 20% system losses se taqseem karke size nikalta hai — phir qareebi standard size (0.5 kW steps) par round up hota hai. Inverter ki capacity ke liye total load bhi check hota hai.
- Bachat ka hisaab (2026 net billing): jo units din me khud istemal hon, un ki qeemat aap ka pura effective rate hai. Jo surplus grid ko jaye, wo sirf Rs 10–11/unit par bikti hai (National Average Energy Purchase Price) — is liye self-use jitna zyada, payback utna tez.
- Misaal (source ki): 5 kW system ~Rs 700,000, ~650 units/month, 75% self-use par mahana faida ~Rs 24,735 aur payback ~28 mahine — Pediastan ka 2026 hisaab, net metering fee ke baghair. Hamara tool by default Rs 150,000 fee jorta hai — fee shamil karne par yehi misaal kul ~Rs 850,000 lagat par payback ~34 mahine banta hai. Tool aap ke apne numbers par yehi formula chalata hai; aap ka nateeja is se mukhtalif ho sakta hai.
- Doosri raaye: Life in Pakistan ki guide 5 kW class ke liye payback table 4–5 saal dikhati hai. Farq self-use, asal rate aur qeemat ka hai — koi ek number sab par laagu nahi hota.
عام سوالاتCommon Questions
بیٹری لگانی چاہیے؟Should you add a battery?
Sirf payback ke liye nahi. 5 kW hybrid system lithium battery ke saath Rs 950,000–1,250,000 tak chala jata hai aur payback lamba ho jata hai. Battery sirf load-shedding backup ke liye lein (Pediastan).
دن میں گھر خالی رہتا ہے — پھر؟What if the house is empty during the day?
Self-use slider 40–50% par rakhein. Export par Rs 10–11/unit hi milega, is liye payback slow hoga. Washing machine, motor aur istri din me chalane se self-use barhta hai.
قیمتیں کتنی پکی ہیں؟How reliable are these prices?
Ye market ranges hain, quote nahi. Brand (Longi, Jinko, Canadian), inverter quality, structure aur sheher ke hisaab se Rs 1–1.5 lakh ka farq aam hai. Hamesha 2–3 installers se quote lein aur Step 3 me asal quote daal kar dobara hisaab karein.
گرمیوں اور سردیوں میں جنریشن؟Generation in summer vs winter?
Solwave ke hisaab se output garmiyon (May–Aug) me ~20% zyada aur sardiyon (Dec–Jan) me ~15% kam hota hai. Tool saal bhar ka average leta hai.
