The Practical Starting Range
If your monthly electricity bill is around PKR 30,000, many homes land in the rough range of 5kW to 7kW. But the right answer depends on how the bill is created, not just the headline number.
When 5kW May Still Be Enough
5kW can still be enough when:
- your daytime usage is disciplined
- summer peaks are seasonal rather than constant
- your home is in a stronger-sun city
- you are willing to keep some post-solar bill instead of chasing zero
When You May Need 6kW or More
The case for 6kW or more strengthens when:
- multiple ACs run heavily in summer
- family occupancy is high during solar hours
- you want stronger offset of a persistently high unit load
- your winter bill also remains relatively elevated
The Risk at This Bill Level
This is the zone where users can make two opposite mistakes:
- undersizing and then feeling disappointed by the remaining bill
- oversizing and paying too much for export-heavy generation
That is why scenario comparison matters more than generic “bill to kW” rules.
Think in Terms of Usage Pattern, Not Ego Size
Some people want the bigger number because it feels safer. But the better outcome is the system that creates the strongest combination of:
- self-consumption
- practical savings
- reasonable payback
- upfront cost discipline
What About Battery?
At this bill level, battery becomes more relevant if your home faces regular outages or if your larger system would otherwise export a noticeable amount of solar at low value. But it still should be judged separately, not added blindly.
Use Your Real Scenario
The Rafiqy Pakistan Solar Calculator is the right next step if your bill is around PKR 30,000. It compares full-system and smaller-system paths so you can see what actually pays off better.
Check whether your PKR 30,000 bill points to 5kW, 6kW, or a different solar decision entirely.
