FAQs

Frequently asked questions

The calculator uses standard engineering rules to size your system, using your monthly units, local sunshine, roof direction, shading and system efficiency. It gives a reliable starting point; the final design and price are confirmed after a site survey.

It depends on your monthly units. As a rough guide, a home using about 600 units a month in Lahore usually needs around a 5 kW system. Enter your bill details in the calculator above for a recommendation based on your own usage.

On-grid systems are the most cost-effective way to cut your bill but switch off during load-shedding. A hybrid system adds batteries so essential loads keep running during outages and at night.

Payback depends on your bill, system size and whether batteries are included. The calculator shows an estimated payback period and 25-year savings for your inputs.

Yes. We provide solar and UPS sales, installation and maintenance across Pakistan.

All panels, inverters, batteries and UPS systems we supply come with the official manufacturer (brand) warranty. Warranty terms vary by brand and model.
