"Fit and forget" is a myth. Like a car, your solar system needs basic care to perform at its peak.

The "Rain Will Wash It" Fallacy

While Malaysia's heavy rain helps, it doesn't remove stuck-on grime or bird droppings. Over 6 months, this build-up creates "hotspots" that can damage cells.

Trexon's Recommended Schedule

  • Every 6 Months: Professional gentle cleaning with de-ionized water.
  • Monthly: Check your app. A sudden drop in one string usually indicates debris (leaves) or shading.

What NOT To Do

  • NO Pressure Washers: High pressure can shatter the glass micro-coating.
  • NO Detergents: Soaps leave a film that attracts more dust.
  • NO Walking on Panels: It causes micro-cracks invisible to the naked eye.
