After-sales support & maintenance
Inspections, cleaning, inverter and battery checks, repairs and warranty support from the engineers who know solar, so your system keeps performing year after year.
Dust, heat and loose connections quietly reduce what your system produces, and in Pakistan's climate dust builds up fast. Regular care keeps your panels, inverter and batteries working the way they were designed to, and catches small issues before they become costly ones.
Visual and electrical checks of panels, mounting, cabling, protection devices and earthing to catch problems early.
Safe cleaning that removes dust and bird droppings so your panels can capture as much sunlight as possible.
We review inverter readings, error logs and settings, and update configuration where needed.
For hybrid systems: connections, charge settings and battery health, so backup is ready when you need it.
