Preventive and corrective maintenance

Professional solar panel maintenance

Regular maintenance can increase your system's output by up to 25%. On the coast, salt and airborne dust dirty panels faster: inspections, cleaning and diagnostics keep them working at their best.

Why maintain your panels?

Without maintenance, you lose money

PV systems are robust, but without inspections they can lose up to 30% of their annual output.

  • Built-up dirt

    Dust, salt, pollution and bird droppings can cut output by up to 25%. Professional cleaning recovers it.

  • Component wear

    Connections, cables and inverter age over time. An annual check spots problems before they become costly faults.

  • Hotspots and micro-cracks

    Hotspots are invisible to the naked eye but reduce output. Only thermography detects them.

  • Structure and fixings

    Frames and roof fixings should be checked every year so they withstand the wind safely.

  • Inverter performance

    A poorly tuned inverter can reduce overall system efficiency by up to 15%.

  • Valid warranties

    Some manufacturers require certified maintenance to keep panel and inverter warranties valid.

FAQ

Questions about maintenance

How often should solar panels be cleaned?

Every 6 to 12 months, depending on the area. On the seafront, near roads or farmland, more often, because salt and dust stick to the glass.

Can I clean the panels myself?

We don't recommend it: climbing on the roof is risky and tap water leaves limescale on the glass. We use osmosis water and tools that won't scratch the surface.

Do you maintain systems installed by others?

Yes. We maintain installations by any installer, brand and model.
