Solar Panel ROI Pakistan 2026 - 5kW System 3.2 Years Me Free?
Last Updated: 23 Oct 2026 | By PakTools Solar Team | LESCO, K-Electric, AEDB Data
Pakistan me bijli Rs. 32/unit se Rs. 65/unit tak chali gayi hai peak hours me. Is liye 2026 me solar lagana kharcha nahi, investment hai. Is guide me hum NEPRA ke real formula se samjhayenge ke 5kW system kitna banata hai, payback kitna hai, aur 25 saal me kitna profit deta hai.
1. Solar System Cost Pakistan Oct 2026 - Real Market Rate
China panels saste hone ki wajah se rate gir gaye hain. October 2026 Lahore market:
• 3kW System (Small Home - 1 AC): Rs. 480,000 - 550,000 - Production 390 units/month
• 5kW System (Most Popular): Rs. 750,000 - 850,000 - Production 650 units/month
• 10kW System (Large Home): Rs. 1,450,000 - Production 1300 units/month
• 15kW Commercial: Rs. 2,100,000
Includes: Longi / Jinko N-Type Panels, Inverex / Growatt Inverter, Structure, Net Metering Green Meter.
2. Kitni Bijli Banegi? - Professional Formula
99% websites jhooth bolti hain. Real formula jo NEPRA aur AEDB use karte hain:
Daily Units = kW × Sun Hours × 0.78 Efficiency Loss
Pakistan me average sun hours 5.2 hain (Punjab 5.5, Karachi 5.3, Islamabad 4.9). 0.78 is liye kyunki dust, heat 45°C, wire loss, inverter loss 22% hota hai.
Example 5kW: 5 × 5.2 × 0.78 = 20.28 units/day × 30 = 608 units/month. Hamare calculator me yehi formula hai.
3. Net Metering Se Paise Kaise Bante Hain? - LESCO Buyback 2026
Net metering ka matlab hai aapki extra bijli WAPDA kharidta hai. 2026 me NEPRA ne export rate Rs. 22/unit fix kiya hai.
Case 1: Aap 600 units use karte hain, Solar 608 banata hai:
Self use 600 × Rs. 32 = Rs. 19,200 bachat + Export 8 × Rs. 22 = Rs. 176. Total Rs. 19,376/month saving.
Case 2: Aap 400 units use karte hain:
Self use 400 × 32 = 12,800 + Export 208 × 22 = 4,576 = Total Rs. 17,376/month.
Isi liye 5kW wala banda jis ka bill pehle Rs. 19,200 tha, ab Rs. 0 ho jata hai, ulta Rs. 176 credit.
4. Payback Period Kitna? - Asal Hisaab
Payback = Total Cost / Annual Saving
5kW Cost Rs. 750,000 / Annual Saving Rs. 232,512 (19,376×12) = 3.22 Years.
Matlab 3 saal 3 mahine ke baad system free. Uske baad 22 saal tak muft bijli. Inverter 10 saal baad change hoga Rs. 150k ka, wo bhi hisaab me hai.
5. 25 Saal Ka Profit - 62 Lac?
2 cheezein hoti hain: 1) Panel har saal 0.7% kam banta hai (degradation), 2) Bijli har saal 8% mehngi hoti hai (last 10 year average).
Year 1 saving Rs. 2.32 lac, Year 10 saving Rs. 4.6 lac, Year 20 saving Rs. 9.9 lac.
Total 25 saal production = Rs. 69.5 lac - Cost 7.5 lac = Net Profit Rs. 62 lac. ROI 826%.
6. FAQs
5kW ke liye kitni jagah chahiye?
550 sq ft shadow-free roof. 10 panels × 580W.
Net metering green meter ka kharcha?
LESCO Rs. 35,000 - 50,000 + application. K-Electric me Rs. 60,000. Time 45-60 din.
Solar pe loan milta hai?
Haan, Meezan Bank, HBL, Bank Alfalah 6% markup pe 5 year loan dete hain. Monthly EMI Rs. 14,500 for 5kW.
CO2 saving?
5kW system saal me 4.38 tons CO2 bachata hai = 200 trees lagane ke barabar.
