Solar Load Calculator Pakistan
Estimate your electrical load, solar system size, inverter capacity, solar panel quantity and battery backup requirement using the appliances you want to run.
This calculator is designed as a practical first-step planning tool for residential and small commercial solar systems in Pakistan.
How the Solar Load Calculator Works
Add the quantity of appliances you want to operate, such as lights, fans, refrigerators, TVs, air conditioners, washing machines and water pumps.
The calculator estimates the combined electrical load and provides a suggested solar system size, inverter capacity, number of 585W solar panels and an estimated battery backup option.

Important: Calculator Results Are Planning Estimates
Actual solar system requirements can vary because appliance power consumption, motor starting current, inverter efficiency, solar panel performance, battery condition, usage hours and future load expansion are different for every site.
Before purchasing equipment, we recommend confirming the final system design according to your actual load and site conditions.
What Determines the Right Solar System Size?
Correct solar sizing depends on more than total appliance wattage. These factors should also be considered.
Starting Current
Motors, pumps, refrigerators and some air conditioners can require higher power while starting.
Backup Requirement
Battery capacity depends on the load you want to run and the required backup duration.
Solar Charging
Solar panel capacity must support daytime load as well as battery charging where backup is required.
