1. Why Cleaning Solar Panels in Dubai Is Crucial

Dubai’s desert environment is awash with dust and airborne sand. If panels stay dirty:

• Efficiency drops 5–25%, often more during sandstorms
  
• You lose monthly energy gains, especially in winter when production dips
  
• Long‑term debris leads to permanent micro‑scratches
  

Studies and field data show regular cleaning improves output by up to 15% annually—and that’s serious money on your DEWA bills.

2. Recommended Cleaning Frequency in Dubai

Season	Frequency	Why
Summer (Jun–Aug)	Every 2–3 months	Intense dust; infrequent rain
Winter (Dec–Feb)	Quarterly	Less dust, occasional rain
Sandstorm Months (Mar, Apr, Sep)	After each storm	High debris load
Autumn/Rainy spells	Mid‑season clean	Remove residual dust and pollen

TIP: After any sandstorm, clean within 72 hours to prevent surface abrasion.

4. Cleaning Methods: DIY vs. Professional

A. DIY Cleaning – Quick & Low‑Cost

• Reporting and panel condition checks
  

Expect AED 150–400 per session depending on roof size and system complexity.
