Solar System for 1,000 Units Per Month in Pakistan 2026
If your electricity meter shows 1,000 units consumed per month, here is exactly what size solar system you need, what it costs, and how quickly it pays back. Updated July 2026 with current market prices.
What System Size Covers 1,000 Units/Month?
| Monthly Units | System Size | On-Grid Price (PKR) | Monthly Savings (est.) |
|---|---|---|---|
| 1,000 units | 10kW | Rs 850,000–950,000 | Rs 50,000–65,000 |
How System Size Is Calculated from Monthly Units
Solar system size (kW) = Monthly units ÷ (30 days × peak sun hours × 0.8 efficiency). In Pakistan with 5 peak sun hours:
| Monthly Units | Formula | System Size Needed |
|---|---|---|
| 200 units | 200 ÷ (30 × 5 × 0.8) | 1.67 kW → 2 kW |
| 300 units | 300 ÷ (30 × 5 × 0.8) | 2.5 kW → 3 kW |
| 500 units | 500 ÷ (30 × 5 × 0.8) | 4.17 kW → 5 kW |
| 700 units | 700 ÷ (30 × 5 × 0.8) | 5.83 kW → 6–7 kW |
| 1,000 units | 1000 ÷ (30 × 5 × 0.8) | 8.33 kW → 10 kW |
Add 15–20% extra to account for dust losses, cable losses, and peak summer demand variations. Pakistan’s summer peak can push consumption 30–40% higher than winter months.
What’s Included in a 10kW Solar System?
- Solar panels: sufficient wattage to produce 1,000+ units/month
- On-grid string inverter or hybrid inverter
- Hot-dip galvanised mounting structure
- AC/DC wiring, circuit breakers, SPDs
- DISCO net meter (bidirectional)
- 5-year installation warranty, 25-year panel performance warranty
Net Metering: How Your Bill Works After Solar
With NEPRA net metering, surplus units exported to the grid are credited at the same rate you pay. During winter or low-consumption months, your export credits roll over to the next billing cycle.
