Solar Panel Cleaning in Phoenix, AZ

We recommend cleaning every 3-4 months for most Phoenix Valley homes due to frequent dust storms and high pollen levels. Homes near construction, agriculture, or with heavy bird activity may need cleaning every 2-3 months. We'll assess your specific location and recommend the optimal schedule.

While you can rinse panels with water, professional cleaning is far more effective. Garden hoses use hard water that leaves mineral deposits, and household cleaning products can damage panels. We use deionized water and specialized solutions that won't leave residue or void your warranty.

Absolutely. Dirty panels in Arizona commonly lose 15-25% efficiency, and in extreme cases up to 40%. A typical home solar system losing 20% efficiency could cost you $300-600 annually in lost energy production. Professional cleaning quickly pays for itself.

Solar panels are durable, but improper cleaning can cause expensive damage. Using abrasive materials, harsh chemicals, or cleaning during hot periods can crack panels or damage anti-reflective coatings. Our professionals use proper techniques, timing, and equipment to clean safely.

We typically clean early morning or late afternoon when panels are cooler. Cleaning hot panels can cause thermal shock and cracking, plus cleaning solutions evaporate too quickly on hot surfaces, leaving streaks and residue.

Yes, monsoon season often requires more frequent cleaning. While rain helps rinse panels, it also brings mud, dust, and debris that can bake onto panels once the sun returns. We adjust our cleaning schedule based on weather patterns and panel condition.
