How Many Solar Panels Do You Need for Your Home in Pakistan? A Simple Calculation Guide

Learn how many solar panels you need for your home in Pakistan with this simple calculation guide by IMH Technologies. Discover system sizes, energy formulas, and expert tips to power your home efficiently.

Introduction

Are you planning to install a solar system but not sure how many solar panels you need for your home in Pakistan?
With rising electricity prices and frequent power outages, switching to solar energy has become the smart choice for homeowners across Pakistan. But before you go solar, it’s important to calculate the right number of panels needed for your daily energy consumption.

At IMH Technologies, we help you understand your energy needs and design the perfect solar solution for your home—efficient, reliable, and affordable.

1. Understanding Your Home’s Power Consumption

To determine how many solar panels your home needs, you must first know your average monthly electricity usage. You can easily find this on your WAPDA or LESCO bill under “Total Units Consumed” (kWh).

Here’s a rough idea:

• Small house: 300–500 units/month

• Medium house: 700–1000 units/month

• Large house: 1500+ units/month

Once you know your monthly usage, you can estimate the solar system size required for your home.

2. Simple Formula to Calculate Solar System Size

In Pakistan, 1 kW of solar panels typically generates around 4–5 units per day (depending on sunlight and location).

Formula:

System Size (kW) = Monthly Units ÷ (30 × 4.5)

Example:
If your monthly electricity usage is 900 units,

900 ÷ (30 × 4.5) = 6.6 kW
So, you’ll need approximately a 7 kW solar system.

3. How Many Solar Panels Are Needed?

Most modern solar panels in Pakistan (such as Inverex, Longi, or Canadian Solar) have a capacity of 550W–600W.

Formula:

Number of Panels = (System Size × 1000) ÷ Panel Wattage

Example (for a 7 kW system with 550 W panels):

(7 × 1000) ÷ 550 = 12.7 → 13 panels required

So, for a 7 kW system, you’ll need 12–14 panels, depending on brand and efficiency.

4. Factors Affecting the Number of Solar Panels

The number of panels required can vary depending on:

• Sunlight Availability: Cities like Faisalabad, Multan, and Lahore receive strong sunlight throughout the year.

• Roof Space: Larger rooftops can accommodate higher capacity systems.

• Appliance Load: Heavy use of air conditioners, motors, and refrigerators increases power demand.

• Battery Backup: Off-grid and hybrid systems require extra panels to charge batteries.

• Panel Efficiency: Premium brands like Inverex Mono PERC or Longi HIMO 7 provide higher output per panel.
