Solar Load Calculator – Easily Calculate Your Home's Solar Power Needs
Thinking of going solar? Not sure how many panels you need or what load your system should handle? Our free Solar Load Calculator makes it easy to estimate how much power your home uses—so you can plan the perfect solar setup without the guesswork.
What Is a Solar Load Calculator?
A solar load calculator is a tool that helps you figure out how much electricity your household appliances consume. It shows the total load in watts and kilowatts, so you know exactly how big your solar system should be.
Whether you live in Pakistan or anywhere else, it’s a must-use tool before buying solar panels, batteries, or an inverter.
Appliances You Can Add in the Calculator
Here’s a list of the appliances you can include in your load calculation:
1 Ton AC
Iron
Fridge
Water Pump
Fan
LED Bulb
LED TV
Washing Machine
You simply enter how many of each appliance you use—and boom! It gives you the total wattage and kilowatt (kW) usage in real-time.
How to Use the Solar Calculator (Step-by-Step)
Select each appliance you use in your home.
Enter the quantity of each item (e.g., 2 fans, 1 fridge).
Click calculate or just view the total power below.
The calculator instantly shows:
Total Power in Watts
Total Load in kW
It’s that easy.
Why This Calculator Matters (My Personal Experience)
When I first considered solar for my home, I had no idea how much power I was using. I bought a smaller system—and guess what? It couldn’t even run the AC and fridge together. After using a tool like this, I realized I needed a 5kW system, not a 3kW.
So trust me, this simple step will save you money, time, and a lot of headaches.
Best Use Cases for the Tool

FAQ,s
A solar load calculator is an online tool that estimates your home’s power usage in watts or kilowatts based on the appliances you use.
If you enter correct appliance data, it gives a close estimate—perfect for initial planning.
Yes, our solar calculator Pakistan is ideal for local conditions, power needs, and common appliances.
You’ll need around 14–16 panels (350W each) to handle a 5kW load, depending on your location and sun exposure.
No, but we also offer a solar panel tilt angle calculator to help you optimize panel direction and efficiency.
On-Grid Systems: Connected to the utility grid, allowing for net metering and reduced electricity bills.
Off-Grid Systems: Operate independently, requiring battery storage to supply power during non-sunny hours.
The choice depends on your location, electricity needs, and budget.
Consider the following when selecting a solar panel:
Energy Requirements: Assess your daily electricity consumption.
Roof Space: Ensure sufficient space for installation.
Budget: Balance between cost and efficiency.
Panel Efficiency: Higher efficiency panels generate more power in limited space.
Warranty and Support: Opt for brands offering robust warranties and customer service.
