Fast, Reliable Solar Panel Cleaning Across Woodland
Solar panel cleaning in Woodland typically runs $150-$380 for a standard residential array, and most jobs are finished in under two hours. Our crews know Woodland’s neighborhoods, its fog patterns, and its roof styles. We’ll scrub the soiling off your panels, check for bird activity, and leave your system producing like it should. Call (877) 550-6892 for a free estimate.
We’re Woodland neighbors who understand what PG&E NEM 3.0 billing means for your true-up statement. Dirty panels during fog season are a double hit: production drops from the fog, then drops again from the grime. That’s where we come in.
Why Gus’s Solar Is Woodland’s Preferred Solar Panel Cleaning Company
Gus Petrakis started Gus’s Solar in 2011 and put his name on the truck. That matters in Woodland, where homeowners on College Street and near Beamer Park have dealt with enough fly-by-night contractors. When you call, a live person answers. Not a voicemail tree, not a call center. Gus answers his own phone, and his crew does the work. No subs, no hand-offs.
We’ve cleaned panels on everything from 1900s Victorians near Heritage Plaza to 1970s ranch homes off Cottonwood Street. Our Solar Panel Cleaning team stocks purified water systems and soft-bristle brushes that are safe for all panel brands. We’re licensed, insured, and background-checked. You’ll know who’s on your roof before they climb the ladder.
Response time to Woodland is same-day for most calls, next-day at the latest. If a storm leaves your array coated in dust and debris, call before 2 p.m. and we can usually be there that afternoon. That’s the benefit of a local crew, not a dispatch board three states away.
Our Solar Panel Cleaning Services in Woodland
Residential Panel Cleaning
Most Woodland homes need cleaning twice a year: once after the tule fog lifts in spring, and once after summer harvest dust settles. We use deionized water and soft brushes that won’t scratch panel glass or void your warranty. A typical single-story ranch in the 95695 zip runs $150-$220. Two-story homes with steep pitches run more.

Commercial Array Cleaning
Woodland’s warehouses along Interstate 5 and East Main Street collect dust faster than residential roofs. We clean commercial arrays from 10 kW to over 500 kW, usually on a scheduled quarterly rotation. Pricing is per-panel, typically $2.50-$4.00 per panel depending on array size and roof access. We’ll work around your operating hours.

Bird & Critter Guard Installation
Woodland’s mature oaks and power-line corridors make pigeon and squirrel nesting a real problem. We install mesh critter guard around array edges that keeps birds out without trapping heat or blocking airflow. On a recent job near Gibson Elementary, bird droppings and nesting material had cut a 24-panel Enphase array’s output by nearly 30%. After cleaning and guard installation, that homeowner’s true-up went back to net-positive. Guard installation for an average Woodland home runs $400-$900 installed.

Debris & Soiling Removal
After wind storms, panels get coated in a fine layer of dust, pollen, and sometimes ash. If you see streaking or a dull film across your array, that’s production you’re losing every day. We remove soiling with purified water, not a hose and hard tap water. Woodland’s well water is mineral-heavy, and letting it dry on panel glass leaves spots that permanently etch the surface.

Trusted Brands We Service in Woodland
We clean and service arrays built with Tesla, Enphase, SolarEdge, FranklinWH, and every major panel brand. Our crew knows the microinverter layout on an Enphase array and the string configuration on SolarEdge systems. That matters when we’re working around wiring runs and critter damage. We stock common replacement parts locally, so bird-damaged wires or failed microinverters don’t leave your system down for weeks.
Common Solar Panel Cleaning Problems We See in Woodland Homes
- Tule fog residue. Woodland’s winter fog leaves a sticky film on panels that plain rain doesn’t wash off. That film cuts production by 10-15% on top of the fog’s natural reduction. Spring cleaning is not optional here; it’s the difference between a true-up credit and a surprise bill.
- Hard water spotting. We’ve seen panels near Woodland’s older neighborhoods, especially east of West Street, that look like they were washed with a sprinkler. Mineral spots from untreated water permanently etch the glass and can’t be buffed out. We always use deionized water.
- Bird nesting under arrays. Pigeons love the gap between your panels and the roof deck. Nests block airflow, droppings corrode wiring, and the mess invites squirrels. Mesh guard is the fix, and it costs far less than replacing a chewed-up optimizer.
- Roof access on older homes. Steep Victorian and Craftsman roofs downtown need different ladder setups and more care. We’ve cleaned panels on homes off First Street where the roofline is a 12/12 pitch and the gutters are original. It takes longer, but it’s never a problem.

FAQs - Solar Panel Cleaning in Woodland
Woodland’s tule fog season runs roughly mid-November through February, and it cuts solar production by 50-70% during peak events. That’s already baked into your system’s winter output. When a sticky fog film builds up on top of that, you lose another 10-15% that the fog alone wouldn’t cause. Clean panels before fog season starts in November, then again in March after the fog lifts. That’s the schedule that keeps your NEM 3.0 true-up from going negative. Call (877) 550-6892 to schedule both cleanings now.
Because under NEM 3.0, the power you export back to PG&E is credited at roughly 25% of its retail value. Your solar only pays off when you use it yourself. During winter, fog already limits production, and dirty panels reduce it further, which means you’re pulling more from the grid at full retail price. Clean panels maximize self-consumption, and self-consumption is the only thing that makes NEM 3.0 math work. In Woodland, that means cleaning before and after fog season, not once a year.
Yes. We clean panels on steep Victorian and Craftsman roofs all over downtown Woodland, including homes around Heritage Plaza and the Beamer Park area. Our crews use harnesses and ridge hooks where needed, and we work carefully around aging underlayment and original gutters. It takes longer than a low-slope ranch roof, and pricing reflects that, but we won’t turn down a steep pitch. Call (877) 550-6892 and describe your roof; we’ll give you a straight number.
Yes. We install stainless mesh critter guard that clips to the panel frame without penetrating the roof or the panel itself. That method doesn’t void Tesla, Enphase, or any other manufacturer warranty. We’ve installed guard on hundreds of Enphase microinverter arrays around Woodland, including systems near Gibson Elementary and along County Road 102. If birds are nesting under your panels, the guard is cheaper than replacing chewed wiring.
We bring ladders and purified water tanks right up the alley. Woodland’s older blocks, especially near Dead Cat Alley and the historic commercial core, have plenty of alley-load garages with tight clearances. We’re used to it. If we can park a truck within 100 feet of the roof, we can clean the array. Our crew works around fences, gates, and narrow side yards without a problem. Call (877) 550-6892 and we’ll tell you exactly how we’d access your roof.
