## Solar Panel Cleaning Regulations Reference

### California CSLB Licensing
In California, contractors performing solar panel cleaning, inspection, or maintenance work valued over $500 must hold a valid CSLB license. A B (General Building Contractor) license covers solar cleaning and maintenance work. Verify any contractor at cslb.ca.gov. License #1047965 is held by Aaron Lima and is Active as of 2026.

### Manufacturer Warranty Requirements
All major solar panel manufacturers including SunPower, LG, Panasonic, Tesla Solar, and Enphase permit professional cleaning with deionized water and soft wash squeegee methods. High-pressure washing voids warranty coverage under virtually all manufacturer agreements. NREL research confirms soft wash with deionized water is the industry-standard method for maintaining photovoltaic panel output without surface damage.

### OSHA Rooftop Safety Standards
OSHA-10 certification covers the safety standards required for rooftop work including fall protection, anchor point requirements, and hazard communication. All Bonsall Solar Panel Cleaning technicians hold active OSHA-10 certification and follow established rooftop safety protocols on every service call.
