Solar questions, answered

Approximately 6 to 8 modern solar panels are needed to run a 1.5-ton inverter AC during the day.

Around 4 to 6 solar panels are required for a 1-ton AC.

A 5 kW system typically needs 8 to 10 panels, depending on panel wattage. With 580 W panels, 9 panels give about 5.2 kW.

Divide your average monthly units by about 125 to get an approximate size in kW for Punjab. Our solar calculator does this for you, and a site survey confirms the final design.

Plan for roughly 80–100 sq ft of shade-free roof per kW on a flat roof with tilted rows. Elevated structures can make better use of roofs with tanks or obstructions.

An on-grid solar system is connected to both the solar panels and the grid. Solar is used first, the grid covers any shortfall, and surplus units can be exported under your DISCO's arrangement.

Top Tier-1 panels like LONGi, JA Solar, Jinko and Canadian Solar are considered among the best in Pakistan.

Only hybrid and off-grid systems (with batteries) keep running during outages. A pure on-grid system shuts down for safety when the grid fails.

Our projects use inverters from brands including Huawei, Growatt, Solis, Sofar and Voltronic, selected to suit each system's size and type.

Lithium (LiFePO₄) batteries last far longer, allow deeper discharge and need less maintenance. Lead-acid is cheaper upfront but needs replacing much sooner.

Yes. Our portfolio includes a 1 MW hospital installation, 500 kW and 400 kW university systems and multiple factory projects from 61 kW to 300 kW.

Ask our team about flexible payment options when you request your quote. Many banks in Pakistan also offer solar financing products.

Most home systems are installed within one to three days once equipment is on site. Larger systems are scheduled in the proposal.

In dusty months, every two to four weeks is typical for city rooftops in Punjab. Watch your monitoring app: a steady drop in daily units usually means it's time to clean.

Quality panels typically carry 25–30 year linear performance warranties and can keep producing well beyond that. Inverters usually need replacing sooner than panels.

Yes. Our washing service includes before-and-after output readings and a report on any issues found.
