Preventive Maintenance in Solar Parks: Why It Matters More Than You Think

April 15, 2025

Preventive Maintenance isn’t just a box to tick—it’s a strategy that saves real kWh and prevents costly surprises.


Every time we carry out preventive maintenance, we always find something that could have become a problem:


Modules with cracked glass—they might seem harmless now, but over time they lead to Riso faults and energy losses.

Rodent activity—small spaces that look innocent today can be entry points tomorrow, damaging cables and components.

Worn-out sealings—humidity finds its way in, leading to corrosion, insulation faults, and long-term damage.


These issues don’t appear on your monitoring dashboard—until it’s too late.


With a solid Preventive Maintenance program, we find and fix these early.

That means higher uptime, fewer faults, and more energy generated—consistently.


🛠️ Preventive Maintenance Prevents Losses.

And that’s not just a saying—it’s proven in every field visit we make.
