Installing solar panels is one of the smartest decisions to reduce energy consumption and commit to a more sustainable model. However, for a photovoltaic system to operate at maximum performance for years, there is a key aspect that is often overlooked: solar panel maintenance.
Although solar systems are designed to be robust and durable, they are not completely maintenance-free. Proper maintenance ensures that the panels generate the expected amount of energy, prevents costly breakdowns and extends the lifespan of the entire installation.
Why is solar panel maintenance important?
Solar panels are continuously exposed to external factors such as dust, rain, salinity, leaves, bird droppings and sudden temperature changes. Over time, these elements can reduce their efficiency if they are not properly managed.
Good solar panel maintenance makes it possible to detect small issues before they become major problems. In addition, it ensures that the installation is operating safely and efficiently, maximizing the return on investment from the very first year.
In areas such as Mallorca, where sunshine is abundant but humidity, wind and salt air are also present—especially near the coast—maintenance becomes even more important.
How often should solar panels be maintained?
The frequency of maintenance depends on several factors: location, type of installation, panel inclination and surrounding environment. As a general rule, at least one complete annual inspection is recommended.
For installations located in rural areas, near the sea or in environments with higher dirt accumulation, a cleaning and inspection every six months may be advisable. This periodic monitoring helps maintain optimal performance and prevents energy production losses.
Solar panel cleaning
One of the key aspects of solar panel maintenance is cleaning. Although rain helps wash away some dirt, it is not enough to remove more persistent residue.
A dirty panel can lose between 5% and 20% of its performance, depending on the level of accumulation. Professional cleaning is carried out using demineralised water and specific tools that do not damage the panel surface, avoiding micro-scratches or deterioration.
It is important not to use abrasive products or carry out improvised cleaning methods that could affect the manufacturer’s warranty or damage the installation.
Technical inspection
Solar panel maintenance is not limited to cleaning the panels. A complete technical inspection includes checking the condition of the inverter, wiring, electrical connections and mounting systems.
Production data is also analysed to detect potential drops in performance that may indicate a hidden issue. This type of analysis allows problems to be anticipated and ensures the system operates within expected parameters.
In addition, periodic inspections ensure that the installation complies with safety regulations and operates without risk.
Preventive maintenance vs. corrective maintenance
Investing in preventive maintenance is always more cost-effective than waiting for a breakdown to occur. A failure in the inverter or a faulty connection can lead to significant production losses and even major system damage.
Preventive solar panel maintenance reduces the likelihood of unexpected shutdowns, optimises energy production and avoids costly repairs. In the long term, this approach translates into greater savings and peace of mind for the owner.
Who should carry out solar panel maintenance?
Although some basic tasks may seem simple, solar panel maintenance should be carried out by qualified professionals. A specialised technician knows the correct procedures, necessary safety measures and critical points of each installation.
In addition, having a professional service ensures that all interventions are properly documented, which is especially important for commercial installations or systems still under warranty.
