“What size solar system do I need?” is the first question almost every buyer in Pakistan asks — and getting it right saves you from both overspending on capacity you don’t use and under-sizing a system that can’t run your home. This 2026 guide from Abu Bakar Solar Kohat (ABS Kohat) makes it simple.
Step 1: Look at Your Electricity Bill
The fastest way to size a system is your monthly units (kWh) — shown on your electricity bill. As a rough rule of thumb in Pakistan’s sunlight, 1 kW of solar generates around 4 units per day (about 120 units/month). Match your system to what you actually consume, especially during the day.
Step 2: Match a System to Your Needs
| System Size | Runs (typical) | Approx. Monthly Units | Best For |
|---|---|---|---|
| 3 kW | Fans, lights, TV, fridge, small water pump | ~350–400 | Small home |
| 5 kW | Above + 1 AC + washing machine | ~600–650 | Mid-size home |
| 6 kW | Above + 2 ACs (managed) | ~700–800 | Family home / shop |
| 10 kW | Multiple ACs, heavy appliances | ~1,200+ | Large home / commercial |
Step 3: Choose Your System Type
- Day-time / battery-free inverter: Cheapest option. Runs your loads directly from solar during the day, no battery. Great for cutting daytime bills (offices, shops, homes with daytime usage). Starts from around Rs 46,500.
- On-grid (net-metering) inverter: Ties to the grid. Still useful, but the economics now favour self-consumption over export.
- Off-grid inverter: Fully independent with battery, no grid needed — ideal for remote areas.
- Hybrid inverter: The most popular choice in 2026 — runs on solar, charges a battery, and falls back to the grid when needed. Best of all worlds.
Step 4: Add the Right Battery
If you want backup during load-shedding or evening use, pair your inverter with a lithium (LiFePO4) battery. See our guide on choosing the best battery to match capacity to your evening load.

Recommended Setups by Home Type
| Your Situation | Recommended Setup |
|---|---|
| Small home, tight budget, daytime usage | 3 kW day-time inverter + panels |
| Family home with 1–2 ACs | 5–6 kW hybrid inverter + panels + 5 kWh lithium battery |
| Shop / small business | 6 kW hybrid + panels + battery for backup |
| Large house / commercial with multiple ACs | 10 kW+ hybrid + panels + 10 kWh battery |
What Does It Cost?
As a rough guide: a 3 kW system starts from a few hundred thousand rupees, a 5–6 kW hybrid system with lithium storage typically lands around Rs 550,000–950,000+, and 10 kW+ systems scale from there.

Frequently Asked Questions
What size solar system do I need for my home in Pakistan?
It depends on your monthly units. As a guide: 3 kW suits a small home, 5–6 kW suits a family home with 1–2 ACs, and 10 kW+ suits large homes or shops with multiple ACs. Check your bill’s monthly units to match precisely.
How much does a solar system cost in Pakistan in 2026?
A complete 5–6 kW hybrid system with lithium storage generally ranges from about Rs 550,000 to Rs 950,000+, depending on brands and battery size. Day-time (battery-free) setups cost much less.
Should I get a hybrid or a day-time inverter?
A day-time (battery-free) inverter is cheapest and great for cutting daytime bills. A hybrid inverter adds battery backup for evenings and load-shedding — the most popular all-round choice in 2026.
How many units will a solar system generate?
In Pakistan’s sunlight, roughly 4 units per day per kW — so a 6 kW system generates around 700–800 units per month, depending on location, weather and system quality.
