The service

What solar panel cleaning is, what a visit covers and where the line is.

The short answer

Solar panel cleaning removes dust, pollen, bird droppings, ash and mineral film from the glass of a rooftop or ground array. Solar Panel Cleaning in Los Altos is booked through pros who cover its 2 ZIP codes, in neighborhoods such as Old Los Altos, Downtown Los Altos Village, and Country Club. In Los Altos, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain. Pros on NorTech set their own price and warranty terms, and you decide who to hire.

What a solar panel cleaning visit includes

What shapes a solar panel cleaning job

These are the things that make one job different from another. Mention them in your notes so each pro can scope your job properly.

Array size and layout
The number of panels, how they are grouped and whether rows are close together decide how much walking and reaching a pro needs.
Roof pitch and mounting type
Flat roofs, shallow pitches, steep tile roofs and ground mounts each carry different access and safety limits.
Type of buildup on the glass
Pollen, dust, bird droppings, sap and hard-water film are removed differently.
Water quality and supply
Mineral-heavy tap water leaves spots as it dries, so pros often bring purified water or ask to connect to an outdoor spigot.
Panel temperature and time of day
Cleaning hot panels causes thermal stress and fast streaking, so pros usually work when the panels are cool.
Where in Los Altos the job is
Los Altos pairs small-town character with serious Silicon Valley wealth. Many homes are original 1950s–60s ranches now being refreshed or rebuilt — owners here want careful, well-documented work that respects the property's value. Tell the pro your neighborhood or ZIP code so they know the age and style of the home.

What is not part of solar panel cleaning

Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.

  • Any job where labor and materials together reach $1,000 or more. Booking notes show when a scope may cross that line, so the right pro takes it on.
  • Electrical work on inverters, wiring, batteries and panel replacement. That is a licensed solar or electrical pro.
  • Roof repair, flashing and resealing roof penetrations. A licensed roofer handles that.
  • Panels the pro cannot reach safely, such as steep roofs without fall protection or arrays near power lines.
  • Coating, sealing or treating panels with products not approved by the manufacturer.
  • Repairing, removing or reinstalling panels. That is solar installation work.

How often to book solar panel cleaning

Panels get dirty on a seasonal rhythm set by dust, pollen, rain and smoke. A routine tuned to your roof keeps output close to what it can be, and each visit is booked with the pro you chose. A plan can be paused or changed.

Every springClear pollen, bird droppings and winter film, and check for branches that now shade the array.
After the dry or dusty seasonWash off dust and mud that rain has not cleared, before the next rainy period bakes it on.
After smoke, ash or stormsBook an extra cleaning if ash, dust or debris coats the glass, and let the pro gently flush instead of wiping.
Every yearCompare production by month and ask the pro to note loose mounts or damaged conduit during a cleaning.

Put solar panel cleaning on a plan

Choose a pro who runs a plan and pick your frequency in the booking card. Before each visit your request goes to the same pro at their price that day, and you are charged only after they accept.

Never book twice
Your standing request goes to your pro before each visit on the schedule you pick, so you do not have to re-book each time.
The same pro each visit
A plan is run by the pro you choose, so your visits stay with them.
Pro-set savings
Many pros take a percent off every visit after the first. You see it before you book.
Charged per visit
No contract and nothing billed for the plan. Each visit is charged like any booking, only after your pro accepts. Pause or cancel anytime.

Before you book solar panel cleaning

Quick things that save a trip. Tick them off as you go; none of it is required to book.

0/7
Let’s get you readyTap a card when you have done it.

Check your monitoring app first

Compare daily output with similar sunny days or the same month last year. A sustained drop can point to dirt, shade or a fault, and a pro can tell you which they see.

Do not climb to look

Roofs are slick and unsafe for non-pros, and panels carry live voltage. Photos from the ground, a window or a zoom lens are enough for the pro to plan.

Find the manufacturer cleaning guidance

Look in your install packet or ask your installer for cleaning rules. Share them with the pro so they follow the same methods and tools.

Note the array layout

Write the number of panels, rows and whether they are on the roof, a carport or the ground. It helps the pro plan time, tools and safety.

Tell the pro about shade and wildlife

Mention branches, nests, or birds that roost near the array, so the pro can bring tools to clear them and flag trimming needs.

Time it for cool glass

Ask for early morning or late afternoon. Cold water on hot panels can stress the glass, and water dries fast and spots in full sun.

Say where in Los Altos you are

Add your neighborhood, for example Old Los Altos, Downtown Los Altos Village, and Country Club, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.

How where you live changes solar panel cleaning

Add your ZIP in the booking card at the top to see weather alerts and the season for your area.

Dust, pollen and ash decide how often panels need washing

Dry, dusty climates and homes near dirt roads, farms or construction collect a fine film on glass that rain only partly clears. Pollen seasons add a sticky layer, and wildfire smoke leaves ash that scratches if wiped dry. Coastal air leaves salt. Tell the pro what lands on your panels and when, so they can flush gently first and then wash with soft tools rather than scrubbing hard.

Fill in the blanks first. The note goes to the pro you choose.

Best time to book solar panel cleaning

Spring Mar to MayFall Sep to Nov

Spring clears pollen and winter film before the sunniest months, when panels matter most. Fall washes off summer dust and bird droppings before storms. Early morning or late afternoon is best, since cold water on hot glass can stress it. In Los Altos, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain.

Often booked together with solar panel cleaning

Book several services with one pro. Pros set their own bundle discounts.

Gutter Cleaning

Debris that gathers at the edge of the roof is cleared along with the panels so water flows off cleanly.

Soft Washing

Roof growth beside the array can be treated gently with low pressure so it does not spread under the panels.

Roofing Inspection

A pro on the roof may spot worn flashing or sealant at attachments, which a licensed roofer can inspect.

Tree Trimming

Branches that shade the array cut output, so trimming them helps cleaning last.
