Solar System Sizing Guide for Karachi Homes
A practical checklist to estimate what information you need before choosing a rooftop or hybrid solar direction — without fake kW packages on this page.
Start with usage, not a random kW number
Online “5 kW package” posts often ignore your actual daytime load, roof shading, and outage pattern. A better approach for Karachi homes is to gather a few facts first, then size the system with an installer.
1. Read your bill pattern
Note monthly units and whether usage is higher in evenings (AC) or daytime (home office, shops). Daytime-heavy loads usually suit solar better for self-consumption.
2. List major appliances
Air conditioners, refrigerators, water pumps, and ironing loads matter. You do not need a perfect audit — a short list helps the conversation.
3. Check roof reality
- Flat or pitched roof?
- Water tanks, dishes, or shade from neighbouring buildings?
- Rough free area you are willing to use?
4. Decide how you feel about backup
If load shedding is your main pain, ask about hybrid options and battery sizing separately from the solar array. Backup is a cost and maintenance decision, not an automatic add-on.
5. Bring documents to the quote call
- Latest electricity bill photo
- Roof photos or a simple sketch
- Preferred contact time on WhatsApp

Frequently asked questions
Can you tell me my exact kW online?
Not accurately from a webpage alone. Exact sizing needs your bill pattern, appliances, roof layout, and backup preference. Use this guide to prepare, then WhatsApp your latest bill.
Should I add batteries in Karachi?
Batteries help during outages but add cost and maintenance. Many homes start with daytime solar and add backup after reviewing usage. Ask our team what fits your situation.
