Output and roof space
On a clean, unshaded Karachi rooftop a 10 kW array is a serious generator, comfortably covering the daytime load of a large home along with air conditioning through most of the year. Expect to allocate roughly 45 to 60 square metres of usable, shade-free roof once walkways and structure spacing are accounted for.
Match the size to your bill, not your neighbour's
Size follows consumption. If your household runs 700 to 1,200 units a month with meaningful daytime usage, 10 kW is usually well matched. Below that you are paying for export you may not monetise well; far above it, 15 kW or more with a load extension is the honest recommendation.
Hybrid or on-grid?
On-grid maximises savings and shuts down during outages. Hybrid adds a battery and keeps your critical loads alive. Most Karachi families we survey end up hybrid, with a lithium pack sized for fans, lights, fridge, router and one AC rather than the entire house.
- On-grid 10 kW — lowest cost, best payback, no backup
- Hybrid 10 kW + LFP battery — backup for critical loads, still net-metered
- Off-grid 10 kW — only where no reliable K-Electric connection exists

The only way to confirm the right size is a roof visit with twelve months of bills in hand. Our survey is free across Karachi and ends with a written proposal.
Frequently asked questions
- How many units does a 10 kW system produce in Karachi?
- Generation depends on tilt, orientation, shading and cleanliness. A well-installed, well-maintained 10 kW array on a Karachi roof is a strong daytime producer year-round; we provide a site-specific estimate after the survey rather than a generic figure.
- Can a 10 kW system run air conditioners?
- During daylight, comfortably — several inverter ACs alongside normal household load. On battery at night, only what you size the pack for.
