Solar panel cleaning and inspection in Valencia — dust taxes every kilowatt.
Sahara dust, pollen and salt film quietly skim 5–15% off your yield. Professional cleaning with thermal inspection from €90 — with production numbers before and after.
Is this you
The panels are due if…
A calima episode painted the sky orange
The coast salts your mornings
No rain has fallen in months
Production sags versus last spring
Birds adopted the array
Nobody has been up there since install
In plain terms
Valencia's sky delivers dust with its sunshine.
Calima dust, coastal salt and months without rain leave a film your production graph notices before you do. Proper cleaning — deionised water, soft tools, no pressure damage — plus a thermal pass that spots failing cells while they're still a warranty claim.

Questions, answered
Asked before hiring us.
How much does panel cleaning cost?
From €90 per residential system including the thermal inspection and before/after production readings. Access and array size set the exact figure — quoted from a photo.
How often should panels be cleaned in Valencia?
Once a year for most roofs; twice near the coast or after heavy calima seasons. Your production graph — or our monitoring — tells you honestly when.
Can't the rain do it?
Rain rinses; it doesn't wash. Valencia's sparse showers leave mineral film and edges of grime that steadily tax output — the before/after numbers make it visible.
Can I clean them myself?
Ground-reachable panels, with deionised water and a soft brush — carefully, yes. Roof arrays are a fall risk and a warranty risk; that's what we're insured for.
What does the thermal inspection find?
Hot cells, failing diodes and loose connectors — problems invisible from below that grow expensive quietly. Caught early, most are warranty claims instead of repairs.
