One clear route: start with a Care Check, then choose the monthly cover that fits your system.
A solar installation is not maintenance-free. Over the years, small issues quietly erode your yield, and you only notice on the electricity bill. Regular maintenance improves safety, performance and the lifespan of your system.
Saharan dust, pollen and salt air can cut output by up to 25%.
Outdated inverter firmware silently limits production and features.
Thermal cycling loosens DC connectors, a real fire and yield risk.
Error codes often go unnoticed for months, costing hundreds of euros.
Degrading cells and wrong charge settings shorten battery life.
Without monitoring, a failed string can go undetected all season.
Cleaning solar panels is not the same as hosing down a window. The glass carries an anti-reflective coating and the aluminium frame has seals that pressure, harsh chemicals or thermal shock will damage. Here is the method we use, and the one to follow yourself if your roof is genuinely safe to walk on.
Early morning or late evening, with cold glass. On a panel sitting at 60 °C the water evaporates instantly and leaves limescale rings that cost you more output than the dust did.
A soft brush or telescopic duster lifts loose Saharan dust. Scrubbing with water before the sand is off scratches the glass, calima dust is abrasive.
Demineralised or osmosis water at normal hose pressure. Costa del Sol tap water is hard and leaves calcium deposits that bond to the glass and attract more dirt.
Microfibre brush or a non-abrasive sponge, working along the frame. Never scrapers, scouring pads or metal brushes.
Rinse top to bottom and let the panels dry on their own. With soft water there is no need to towel off.
Compare the next day's production curve in your monitoring app against the days before. No improvement means dirt was never the issue, usually a dropped string, a failed optimiser or an inverter throttling on heat.
On the Costa del Sol the rule of thumb is twice a year, but it depends heavily on where the array sits. After a heavy calima episode, bring the clean forward: dried Saharan mud left by dust-laden rain is what really costs you output.
| Installation setting | Recommended frequency |
|---|---|
| Inland home, no building work nearby | 1–2 times a year |
| Within 2 km of the sea (salt air) | Twice a year |
| Next to fields, construction or a dusty road | Three times a year |
| After a calima followed by rain | One extra clean |
If the roof is pitched, over three metres high, or you would have to stand on the panels, don't. Most domestic solar accidents here are falls during cleaning, not electrical faults.
This coast combines three things almost nowhere else in Europe has at once: Saharan dust, salt air and months without rain. The same installation soils far faster in Málaga than it would in northern Spain.
During a calima episode an easterly wind carries fine Sahara particles onto the glass. Add a light shower and it bakes into a film of dried mud that will not wash off. This is what triggers the sudden 'my panels look filthy' calls we get overnight.
Within two kilometres of the coast, marine aerosol leaves a salt layer that grabs and holds dust. It also accelerates corrosion on mounting rails and bolts, something we inspect on every visit.
Spring pollen, construction dust in developing areas, and up to six months without useful rain. Rain here rarely cleans anything: it arrives loaded with suspended dust and often leaves the glass worse than before.
A single opaque spot on one cell can trigger the bypass diode and switch off an entire section of the panel, and creates hotspots that permanently damage the module.
Real prices, no 'contact us for a quote'. All amounts are for installations up to ten panels with safe roof access; above ten panels the per-panel surcharge shown applies.

This hillside villa had a thick film of dust, pollen and calima sand on all 29 panels. We deep-cleaned every module and carried out a full maintenance check of the Huawei inverter system — so the installation produces at full power again.
290 €— Cleaning of 29 panels + system check, excl. VAT
This customer had no overview at all: the app showed nothing because a damaged communication cable meant consumption and production were no longer reported. We cleaned all 28 panels, repaired the cable, fixed the fault, migrated the system from Huawei to our own customer portal and set up a new login — everything delivered working, with full insight into yields again.
385 €— Cleaning of 28 panels + fault repair and portal migration, excl. VAT
Palms, trees and several roof levels cast moving shade over this installation all day long. Shade on just one panel can drag down a whole string, so after deep-cleaning all 24 panels we added extra optimisers to the shaded modules. Each panel now works independently at its own maximum, so the system makes the most of every hour of sun.
245 € + 95 €— Cleaning of 24 panels 245 €, each extra optimiser fitted 95 €, excl. VAT
On this tiled roof in Vélez-Málaga, dust, pollen and calima sand had built up a visible film over all 12 panels. We rinsed and brushed every module clean with pure water and a soft telescopic brush — no high pressure, no detergents — and checked mounting, cabling and yield while we were on the roof. The panels now face the sun spotless again.
150 €— Cleaning of 12 panels incl. visual check, excl. VAT

At around 1,750 kWh/kWp a year, the Costa del Sol out-produces almost anywhere in Europe, and soils faster too. Every percentage point lost to dirt is money you never recover over the life of the system.

The Care Check is the entry point of Mi Techo Care: one complete on-site health check of your installation, with a digital report you keep. Calculate the exact price for your system in the calculator below. When Care is contracted together with a new Mi Techo installation, no start Care Check fee is charged: the handover inspection serves as the start inspection. Existing installations, including those installed earlier by Mi Techo Solar or by others, retain the one-off start Care Check.
One-off jobs, no contract. Prices per visit across Málaga, Marbella and the Costa del Sol, VAT excluded. Care Plus includes annual cleaning around month 12; Care Premium, every six months. Cleaning is not included in Care Essential.

On the Costa del Sol the biggest production killer is not rain but calima: Saharan dust leaves a fine layer that can cut output by 10% to 25% in summer. That is why we advise a cleaning after every strong calima episode plus one annual inspection. See the solar panel maintenance guide or see our maintenance case studies with real prices.
