Why South Bay solar panels need professional cleaning
The South Bay is one of the hardest climates in California for solar panels. Coastal cities like Redondo Beach, Manhattan Beach and Hermosa Beach get a daily layer of marine-layer film and salt deposits. Inland communities — Hawthorne, Torrance, Lawndale, Gardena and Inglewood — sit next to the 105, 405 and 110, picking up freeway dust and brake-pad particles year-round. Add long stretches with no rain and you get panels that quietly lose 10–25% of their output between cleanings.
We restore that lost production. Our team uses deionized (purified) water, soft panel-safe brushes and no harsh chemicals — methods that meet the cleaning guidelines of every major panel manufacturer including LG, REC, Q CELLS, SunPower and Panasonic.

Solar panel cleaning FAQs
How much does solar panel cleaning cost in the South Bay?
Most South Bay residential systems fall between $150 and $400 per visit depending on system size, roof pitch and access. Every quote is free — call 323-372-6020.
How often should South Bay solar panels be cleaned?
Every 6–12 months for most homes. Coastal Redondo/Manhattan/Hermosa systems collect marine-layer film faster and often benefit from twice-a-year service.
Do you use deionized water?
Yes. We feed water through a multi-stage carbon + resin filter so it leaves our brush at 0 TDS — spot-free drying with no mineral residue blocking sunlight.
Will cleaning void my panel warranty?
No. We follow manufacturer guidance: soft brushes, purified water, no harsh chemicals and no high pressure. That keeps you inside warranty terms for LG, REC, Q CELLS, SunPower, Panasonic and more.
Can I just clean them with a garden hose?
We don't recommend it. South Bay tap water is hard, and the minerals it leaves behind become white spots that block sunlight — the opposite of what you want.
Will I actually see a production increase?
Most South Bay homeowners see a measurable 10–20% jump in daily kWh on their monitoring app within the week after a professional clean — especially after the first cleaning.
