What a solar panel cleaning quote in Cyprus should say
Solar panel cleaning quotes in Cyprus move with panel count, roof access and water source. Here is the scope to insist on in writing before you accept one.

Cleaning quotes are hard to compare because the word "cleaning" covers anything from a hose run over the modules to a service visit that reads the inverter log, checks every clamp and records the output before and after. Get the scope in writing first, then compare prices. What actually moves the figure is the number of modules, how someone gets safely onto the roof, where the water comes from, and whether anything electrical is inspected while they are up there.
Those ranges are read from our records at page load, each with its sample size and the month it was collected, in the same way the price section of this site handles every other job. Treat them as a sanity check on the quotes you receive.
Why written scope matters
Soiling in Cyprus is not the polite grey film that northern European guidance is written for. Spring brings Saharan dust episodes that leave a bonded layer rain does not lift. Coastal roofs collect a salt crust — in Kato Paphos the air is salt-laden enough that fixings are specified marine-grade as a matter of course, and the same air deposits on glass. Inland, across the Nicosia plain and the farmland that surrounds it, it is agricultural dust and pollen. In central Limassol, where high-rise construction has been continuous, it is cement dust, which is the worst of the lot because it sets.
Each of those needs a different method, and a quote that does not name the method is one you cannot hold anyone to. Losses from soiling are also gradual, so nobody can tell after the fact whether a visit was worth paying for — unless the reading was taken.
The eleven items a quote needs
Ask for these as lines on the quote, not as reassurances on the phone.
- Module count and array location. How many panels, which roof planes, and whether a ground mount, carport or pergola array is inside the price or outside it.
- Access method and who supplies it. Ladder, roof anchor, scaffold tower or mobile platform. On the hillside plots above Peyia, where access roads limit vehicle size, a platform may not physically reach the property, and that changes both method and price.
- Water source and water quality. Whose tap, whose tank, and whether the water is deionised or straight off the mains. Cypriot mains water is hard enough that it dries to a mineral film, so a rinse with untreated water can leave the glass worse than a careful dry brush would have.
- Cleaning method. Pole-fed brush, hand wash, what is used on the frames, and what is used on stubborn deposits.
- What is explicitly not touched. Inverter internals, DC isolators, the roof membrane itself. A clear exclusion protects both sides.
- Output reading before and after, with the figures written on the job sheet. This is the single line that turns a clean into something you can evaluate.
- Inverter and monitoring check. Whether the error log is read and dated, and whether you are sent it.
- Fixings and clamp inspection. A visual check of clamps, rails and earth bonding. On any sea-facing roof this matters more than the glass does.
- Debris and vegetation. Bird nesting under the array, palm litter, leaf build-up at the lower edge — whether removal and disposal are included.
- Frequency and repeat pricing. What a second visit costs, and whether a contract rate differs from a one-off call.
- Insurance and who carries the height risk, plus the price basis in plain words: per panel, per visit, or per hour.
Eleven lines sounds like a lot for a small job. It fits on one side of a page, and it is the difference between three quotes you can rank and three numbers you cannot.
Payment stages
Cleaning is a short job with almost no material cost, so the payment pattern should look nothing like a build.
A deposit is not normal for a single visit. Payment on completion, against an invoice showing the VAT number, is the standard. If a deposit is requested, ask what it is securing — on a short job with no ordered parts, the answer is usually nothing.
Annual or quarterly contracts are different. Billing in advance per period is reasonable there, but the contract should say how many visits that period buys, what happens to an unused one, and how you cancel. Get the notice period in writing before the first payment rather than after the third.
If the visit turns into a repair — a corroded clamp, a failed isolator, a module that has to come off — that is separate work at a separate price, agreed before it starts. A cleaning invoice that arrives with parts on it that you never approved is a dispute waiting to happen.
Variations and how they are priced
These are the things that legitimately push a quote up, and knowing them means you can tell a fair variation from an invented one.
Access. Anything above ground-floor height, or any roof that needs an anchor point or a tower, adds time before a single panel is touched. Two identical arrays, one on a bungalow in Aradippou and one on a fourth-floor block in Strovolos, are not the same job.
Distance. Travel time is priced into day rates, and the further a provider is from their base the more of it there is. Around Polis Chrysochous, where most contractors are still based in Paphos, that gap is real and it shows up in the quote.
Bonded deposits. Cement dust from a neighbouring site, hard-water scale from a previous rinse, or a salt crust that has baked on through summer all need a second pass. Ask how that is charged before the second pass happens.
Bird fouling and nesting. Removing a nest is not cleaning. It is a separate task, it sometimes needs mesh fitted afterwards, and it should be priced as its own line.
Array type. A ground mount you can walk around is quicker than a pitched tiled roof, and a flat roof with ballasted frames sits between the two.
Season. In July and August roof surfaces are hot enough that work moves to early morning, which shortens the working window on each visit.
Red flags
A price with no module count. If nobody has asked how many panels you have, nobody has priced your roof.
A pressure washer. High-pressure water at the module frame drives moisture past the seal. It is the fastest way to turn a cleaning bill into a replacement bill, and no reputable provider offers it.
Opening the inverter without registration. If a cleaner offers to "have a look inside" the inverter, ask what they are registered as. The Cyprus Scientific and Technical Chamber maintains the register that answers that question.
A guaranteed percentage gain. Covered above, and a line you will hear often enough to be ready for it.
No invoice, cash only. Beyond the tax question, it leaves you with nothing to point at if the glass is scratched.
"Free inspection" conditional on approving repairs on the spot. Ask for the findings in writing and take a day.
Common questions
How many visits should a quote assume in a year?
There is no single interval that fits the island, so a quote that names one before seeing your roof has assumed it rather than assessed it. What sets it is your surroundings: a sea-facing roof, a site near active construction, farmland upwind, or overhanging trees all shorten it. Monitoring output over a year tells you more than any rule of thumb, which is why the before-and-after reading on the job sheet is worth insisting on.
Is doing it myself cheaper than accepting a quote?
On a low accessible roof, with soft water and a soft brush, the wash itself is within reach. What the quote buys that a bucket does not is the inspection, the before-and-after reading and someone else carrying the height risk. The array also has to be isolated at the DC side before any module or connector is disturbed, which is where a self-clean stops being a saving.
Does cleaning affect the warranty?
It can, in both directions. Some manufacturers require documented maintenance, and some void cover for abrasive or high-pressure cleaning. Read the module warranty before the first visit and keep the job sheets, because a claim years later will ask for them.
Is a maintenance contract better than one-off visits?
Priced per wash alone, a contract is rarely cheaper. Priced as scheduled inspection with cleaning attached, it often earns its keep by catching a failing string early.
Who is qualified to do this work?
Washing glass needs competence at height and the right method. Anything touching the DC or AC side of a grid-connected system needs an appropriately registered electrical professional, and the Electricity Authority of Cyprus treats the connected installation as something only qualified people alter.
