This estimate is based on average sun hours in your city. However, the final design and price are confirmed after a free site survey by our engineer.
How the solar calculator works
Because every roof and every bill is different, this free solar calculator helps homes and businesses in Pakistan choose the right solar system size. First, pick the bill method if you know your monthly electricity bill. Otherwise, use the appliance method to plan backup for fans, ACs and a fridge.
1. Add your usage
First, type your monthly bill. Alternatively, tap the appliances you run at home or office.
2. Choose your city
Since sun hours differ from Karachi to Islamabad, the estimate matches your location.
3. Pick your backup
Tell us if you need power during load shedding. After that, we pick Hybrid or On-Grid for you.
4. Get your quote
Once the calculation is done, see your inverter, panels and units. Next, send them on WhatsApp for your exact price.
Before you buy any system, it helps to know your real power needs. Also, a right-sized system saves money, because you do not pay for extra panels. For example, a home with two inverter ACs needs a different system than a home with fans only. Moreover, sun hours change by city, so the same bill needs a different system in Quetta than in Lahore. Finally, send your result on WhatsApp, and our team will confirm the best Inverex model for you.
Solar calculator FAQs
How do I know what size solar system I need in Pakistan?
Enter your monthly bill or appliances first. Next, the calculator converts the bill into units. Finally, it divides them by the sun hours of your city to find the inverter size.
Should I choose On-Grid or Hybrid solar?
If you only want to cut your bill, On-Grid works with net metering and needs no battery. Hybrid, however, adds a lithium battery, so you keep power during load shedding.
How many solar panels do I need for a 5 KW system?
Because we use 620W panels, a 5 to 6 KW inverter usually pairs with 9 to 10 panels. As a result, you need about 300 sq ft of roof.
Is the result the final price?
No, it is only an estimate. However, you can send it on WhatsApp, and we confirm the exact quotation after a free site survey.
