How Much Electricity Can You Save with a 5kW–20kW Solar System in Peak Summer
Thinking of going solar this summer? Great choice! But the big question remains:
“How much electricity can I actually save with solar in Pakistan?”
If you’re living in Lahore, Islamabad, Sialkot, Faisalabad, or any city in Punjab, chances are you’re already facing brutal electricity bills from using air conditioners, fans, water motors, and other summer appliances. Installing a solar energy system — especially during the April to August peak sunlight months — can cut your bill by up to 95%.
In this blog, we break down the electricity savings, bill reduction, and ROI you can expect from the most popular solar system sizes in Pakistan: 5kW, 10kW, 15kW, and 20kW.
Why Summer Is the Best Time for Solar Savings
- Sunlight is strongest from April to August
- Air conditioners run more, so your solar offset is higher
- Net metering credits stack up faster
- More savings = faster payback period
Savings Comparison Table (Summer 2025)
| System Size | Avg Units Produced (Monthly) | Approx Monthly Bill Offset | Estimated Monthly Savings (Rs.) | ROI (Years) |
| 5kW | 600–700 units | 100% offset (small homes) | Rs. 15,000–18,000 | 3.5–4 |
