Solar Panel Maintenance in Marbella

Preventive maintenance

A photovoltaic system does not need much, but it does need checking. We inspect connections, mounting structure, protections, inverter condition and production data against the original design.

Most performance losses we find do not come from the panels but from silent faults: a disconnected string, a failed optimiser or an inverter setting nobody has reviewed in years.

• Full electrical and structural inspection
• Inverter and protection checks
• Actual versus expected production comparison
• Clear written report with recommendations

Solar panel cleaning

On the Costa del Sol dirt is not a minor detail: airborne dust, salt from the nearby sea and calima episodes leave a layer that measurably reduces output.

We clean with demineralised water and specific equipment, with no abrasive products or pressure that could damage the glass or the panel seals.

• Cleaning with demineralised water
• No products that damage glass or seals
• Recommended 1-2 times a year in coastal areas

Repairs and diagnosis

If your system produces less than it should, shows inverter errors or has simply stopped working, we diagnose and repair it.

We locate the exact fault, explain what happened and quote the repair before touching anything. We also handle manufacturer warranties when the equipment is still covered.

• Diagnosis of production drops
• Replacement of inverters, optimisers and protections
• Manufacturer warranty management
• Repairs on third-party installations

Monitoring and follow-up

We leave your system monitored so you can see production from your phone and so any performance drop is spotted within weeks, not when a strange bill arrives.

For second-home owners this matters even more: the property can be empty for months while the system stays under watch.
