Solar panel repairs in Mallorca: what to do when your system underperforms
Your solar system is designed to produce energy consistently, but over time faults can appear that affect performance. Solar panel repairs in Mallorca are the right solution when you notice the system is not working as it should. At Greentech Balear, as an installation company on the island, we carry out this type of technical work to get your equipment back to normal.
It's not just about replacing a part: a proper repair means identifying the root cause, checking the affected components and ensuring the whole system operates safely again.
Signs that indicate the need for a repair
Solar systems don't always give a clear warning with a total shutdown. Often faults show up gradually or through indicators on the inverter. Here are some signs that might make you suspicious:
- The inverter shows an error light or switches off intermittently.
- Energy production is lower than usual without changes in the weather.
- Monitoring records sudden drops or abnormal values.
- You hear strange noises from the equipment or detect burning smells.
- The system disconnects frequently, especially on very sunny days.
If you notice any of these symptoms, it's best not to wait for the problem to get worse. A timely check can prevent major damage and keep the system in optimal condition.
Common solar panel repair tasks
In a solar system, the elements that most often require repair are the inverter, the wiring and the electrical protections. The image accompanying this article shows a technician working inside a wall-mounted unit, probably an inverter, with the casing open and access to the wiring. This type of work is common when faults are detected in connections or internal components.
Some of the most common repairs include:
- Replacement of terminals or connection blocks showing signs of overheating or loosening.
- Repair of damaged wiring caused by rodents, moisture or simply age.
- Check and replacement of electrical protections such as fuses or residual current devices.
- Diagnosis and repair of the inverter, which may require a specialised technician.
- Tightening of loose connections that cause voltage drops and performance losses.
Every system is different, so the first step is always an accurate diagnosis. At Greentech Balear we have experience in solar systems and can assess your specific case.
How we handle a fault in your solar system
When you contact us about a problem with your system, we follow an orderly process to locate the cause and propose the right solution. The goal is for you to understand what's happening and what will be done.
- Initial interview and review of history: we ask about the symptoms and review the system's history if available.
- Visual inspection and electrical checks: we check the inverter, wiring, protections and panels to detect obvious anomalies.
- Diagnosis with measuring instruments: we use tools such as multimeters or clamp meters to verify voltages and currents.
- Repair quote: we explain what's wrong and present a proposal with the necessary actions, with no obligation.
- Carrying out the repair: once approved, we perform the work with suitable materials and following safety regulations.
- Final tests and verification: we check that the system works correctly again and inform you of the result.
This procedure allows us to handle both small repairs and more complex faults affecting the inverter or several components at once.
Prevention: the best ally to avoid costly repairs
Although repairs are sometimes inevitable, regular maintenance reduces the likelihood of faults and extends the system's lifespan. At Greentech Balear we offer maintenance services for solar systems, including checking connections, cleaning panels and verifying electrical parameters.
Also, if your system is old or has been exposed to adverse conditions, a preventive check can detect weak points before they become faults. In Mallorca, with hot summers and heavy rain episodes, it's advisable to check the system at least once a year.
If you suspect your system needs a repair or simply want to make sure everything is working correctly, don't hesitate to contact us. We'll be happy to visit your property and offer a professional diagnosis.
