Maintenance and Cleaning of Solar Panels on the Costa Blanca
Recover 100% of your plant's performance by maximizing production and savings
It’s a technical fact that many people ignore: a dirty or improperly maintained installation can suffer efficiency losses of up to 20%. This means that you are wasting a fifth of the energy you should be generating and saving.
In our Levante area, the challenge is greater. Not only do we face dust; calima (mud rain) and sea saltpeter are silent enemies that adhere to the surface of the glass and corrode the components if not treated in time. Thinking that “rain washes it off” is a myth: it often only fixes the dirt further.
Preventive Maintenance
Comprehensive inspection: Periodic review of panels, inverters and all wiring to ensure safety.
Professional cleaning: Washing of photovoltaic modules with specialized techniques to remove embedded dirt and maximize production.
Structural verification: Review of fastenings and anchorages to ensure wind stability.
Corrective Maintenance
Expert repairs: Replacement and repair of defective components (inverters, optimizers, etc.).
Attention to breakdowns: Agile response to urgent failures that stop your production.
Technical resolution: Accurate diagnosis of electrical faults or unexplained production downtime.
Intelligent Monitoring
Continuous monitoring: Remote monitoring of plant performance in real time.
Alert System: Automatic detection of incidents before you realize it.
Detailed reports: We send you production and energy efficiency reports so you can see your real savings.
Frequently asked questions on cleaning and performance
My installation was not done by Energías Renovables HG, can I contract you?
Of course. We know that many installation companies have disappeared in recent years leaving “orphaned” customers. We perform an initial audit to verify the state of your installation (whoever installed it) and we assume its maintenance and cleaning from that moment on.
Can I clean the panels myself with a hose?
We do not recommend it. The tap water in our area (Alicante/Valencia) has a lot of lime, which dries leaving white spots that create shadows on the photovoltaic cells. In addition, the thermal shock (cold water on hot panel) can micro-crack the glass. We use osmosis water and special rotating brushes that do not scratch the surface, guaranteeing a perfect finish without residues.
It has rained mud (calima), is it urgent to clean them or do I wait until it rains?
Mud or haze rain is very damaging. Unlike normal dust, mud adheres and creates an opaque layer that can lower performance by more than 40%. If left too long, it can cause “hot spots” that irreversibly burn panel cells. We recommend immediate professional cleaning after such episodes.
How much money do I lose if I don't do maintenance?
Industry studies indicate that an installation without maintenance can lose between 15% and 25% of annual production due to dirt and small undetected electrical faults. The cost of maintenance is only paid for by the extra energy that you will recover after the overhaul.
Is maintenance mandatory to maintain the equipment warranty?
In most cases, yes. The manufacturers of panels and inverters usually require in their “small print” that demonstrable periodic revisions are made to cover failures under warranty. Our technical report serves as official proof before the manufacturer.
I have batteries installed, do you also check them?
Yes, batteries are the most expensive and delicate component. In our preventive maintenance we check the state of health (SOH), charge cycles, operating temperature and terminal tightening to avoid false contacts that can shorten their useful life.
What happens if my inverter fails and stops producing?
If you’ve signed up for our remote monitoring, we’ll probably know about it before you do. We’ll receive an automatic alert, diagnose whether it’s a network or equipment failure, and call you to coordinate a quick solution, minimizing the time you’re without power.

Your solar installation is a profitable investment, but only if it works 100%. Every day that passes with dirty panels or a hidden breakdown, you are losing money.
In Energías Renovables HG we offer you a customized maintenance plan so that you only have to worry about enjoying your free energy.
