Solar Panel Cleaning Service, Visalia, CA

The materials used to make solar panels may most resemble windows, but our natural tendency is to think of them as some nobler sort of roofing tile. They're up on top of the house, quietly and reliably doing their small part to save the Earth while saving homeowners money. The very last thing most of us ever think of doing with roofing tiles is washing them. Isn't that what rain is for?

In fact, solar power panels do need to be cleaned from time to time. For several reasons, one of them being that the work is typically done up on the roof, it is usually recommended that solar power customers consult a specialist. That recommendation aside, it's still best to provide a guide to cleaning solar panels whether it be to inform customers or to direct homeowners, should one feel adventurous enough to do the work on their own.

Considerations

The master source when it comes to whether, when, and how one should wash their solar panels has got to be the panels' manufacturer. Check their instruction manual before anything else, because that's how to move from "solar panels, generally" to "your particular solar panel."

Beyond this, there is a general procedure for this product. First, inspect the panels. At this point, the search is for damage, not dirtiness, particularly exposed wires and cracks or chips in the glass. If there's no damage and the solar panels were cleaned within the past three to six months, it's usually safe enough to rinse the surfaces using de-ionized water. In most of the country, periodic rainfall may have kept the panels fairly clean, especially if they're slanted at an angle rather than laying flat on the roof.

​Where customers in most of the country might not need to hire a pressure washing service, Visalia customers have to overcome the Southwest's unique weather patterns. Yes, there's plenty of sunshine. But there's also the reality that in the southwest, rainfall is scarce to nonexistent for great portions of the year. Dirt and soot can really accumulate, especially near roads and highways. So can tree sap, dust, bird droppings, ashes, oily grime and bugs.
A mere rinse very well might not get the job done, and using soapy water on a solar panel can be a dicey proposition. Some panel surfaces are delicate enough to chip under the roughness of a mere wet rag. No one wants to smear three months of scum all over the glass. Finally, there is the small problem of possibly falling off the roof. There are reasons this work is typically left to a solar panel cleaning service.

Using detergents improperly, or even just the minerals in Western tap water can leave behind residue and a build-up of mineral grit. Alcoholic solutions might be needed to dissolve months'-old stains. Any chip, smear, or deposit negatively impacts the performance of the system as a whole. Choosing a professional solar panel washing service in Visalia is the safest option both for the customer's health and the customer's wallet.

How the Experts Do the Job

After inspecting both the panels and - in Western cities like Visalia - the watertight integrity of the roof itself, the pro will soap up the panels using a strip washer on an extension pole. After this, he or she will rinse the panels using a de-ionized water-fed pole such as a Tucker pole.

Solar panels will heat up considerably in the California summer sun. They can and will actually crack if washed when too hot, especially once they've reached 140–150 degrees Fahrenheit. Accordingly, our workers will invariably bring along a temperature gun.

Cleaner Panels, More Clean Power

The power gains from using a solar panel cleaning service are significant. In an experiment conducted at Google's 1.6 Megawatt Mountain View CA solar farm it was found that washing solar panels that'd been used for 15 months doubled their electricity output. Further, professional cleaning yielded a 12% higher output than cleaning by rain.

The evidence keeps mounting. Solar panels cleaned once annually have been found to produce 3.5% more electricity, and those cleaned twice a year yield 5.1% more than panels left to the elements without being cleaned. Uncleaned solar panels can be expected to generate 15% to 25% less electricity.

This in turn suggests how a homeowner can discern when to call an expert for pressure washing assistance. Monitor any reductions in power output from your solar panels. Let those reductions tell you when to call for professional assistance, and keep your system working at its optimal level.
