Frequently Asked Questions

What is included in Northern Solar's Operation & Maintenance (O&M) services?

Our comprehensive O&M services include professional surface cleaning of solar PV panels, thermal and visual inspections, wiring management, real-time performance monitoring, diagnostic reporting, inverter/panel repairs or replacements, and full warranty claim administration.

How often should solar panels be cleaned and inspected in Malaysia?

In Malaysia’s tropical climate, ambient dust, haze, atmospheric pollution, and bird droppings can reduce energy yield by 10% to 25%. We recommend conducting routine solar panel cleaning and structural/electrical inspections 1 to 2 times per year to keep generation at peak capacity and safeguard component warranties.

Can Northern Solar maintain or repair my system if it was installed by another company?

Yes. Our SEDA GCPV-certified in-house engineers and technicians provide full O&M services for both existing Northern Solar clients and third-party installed systems across residential, commercial, and industrial properties in Malaysia.

Why shouldn't I clean or inspect my rooftop solar panels myself?

Rooftop solar maintenance carries significant electrical shock hazards and fall risks. Additionally, using tap water with high mineral content or abrasive tools can scratch anti-reflective panel glass and void manufacturer warranties. Our team utilizes specialized, non-abrasive cleaning equipment and certified safety gear.

How can I tell if my solar panel system requires troubleshooting or repair?

Common indicators that your system needs attention include:

  • A sudden drop in output on your mobile monitoring app
  • An unexpected spike in your monthly TNB electricity bill
  • Red fault indicators or error codes displaying on your solar inverter
  • Visible debris, discolored cell hotspots, or physical roof damage around mounts
