Prevent Errors, Secure
Performance Maintenance & service for residential customers
Your energy system works reliably for you day after day—generating electricity via the solar panels, storing it in the battery, and perhaps also charging your electric vehicle conveniently at the Wallbox. To ensure it stays that way in the future, regular inspections, care, and professional maintenance are essential. Our trained team monitors your system, detects potential issues early on, and ensures that everything runs smoothly.
Even though modern systems are largely low-maintenance, minor faults or performance drops can creep in over time—due to weather, dirt, or software anomalies. These often go unnoticed, but in the long run, they lead to reduced yields or preventable outages.
Our experienced service team ensures that your entire system runs optimally, all components stay perfectly synchronized, and you enjoy full performance and safety over the long term. We inspect your system as a whole—technically, electrically, and on the software side.
Our experts and technicians receive regular training, possess a wealth of experience and the necessary know-how, and use state-of-the-art technical equipment to locate and resolve even the most hidden faults.
Your benefits at a glance:
- All-round worry-free service for solar panels, battery storage, and wallboxes
- Early fault detection through monitoring and annual maintenance
- Maximum yields and longevity thanks to perfectly optimized systems
- Written documentation for transparency and warranty security
- Expert support over the phone or directly on-site
Module performance determination
With a professional module performance measurement, we verify that your installation is delivering the promised results. Our team measures the real-world performance of your modules, identifies discrepancies at an early stage, and provides clear documentation in an inspection log. This ensures your photovoltaic system operates at peak efficiency and avoids any lost revenue. Particularly after several years of operation, this check is highly recommended to confidently exclude losses in performance or installation faults—while maximizing the lifespan of your system.
Module replacement
Whether a module is faulty or showing a drop in performance, we provide a quick and hassle-free solution. Our specialists assess if a replacement is required and source a suitable replacement module—even if the original manufacturer no longer exists on the market. Operating manufacturer-independently allows us to respond flexibly and guarantee technical compatibility.
Our focus remains consistent: ensuring your installation rapidly returns to peak output while remaining economically viable. If desired, we will take care of the entire procurement and handle all documentation for your files.
Inverter replacement
The inverter is the core component of your installation, converting the generated direct current into usable alternating current for your home. As these units have a shorter service life than solar modules—averaging approximately ten years—regular monitoring is vital. We perform operational checks, software updates, and visual inspections of the wiring to identify faults at an early stage.
If a replacement is required, we cooperate with leading manufacturers and are frequently able to procure replacement devices on the same day. We operate as certified service partners for SMA, Fronius, Power-One, Siemens, Platinum, Kaco, Kostal, and Solarmax.
Drone Thermography
When dealing with large or hard-to-reach roofs, we utilize cutting-edge drones fitted with thermal imaging technology. This type of thermography enables a rapid, non-contact aerial analysis of your installation—without requiring scaffolding or roof access.
The scan visualizes so-called "hotspots," indicating locations where modules are overheating or faulty. Such irregularities can result in losses in performance, accelerated wear and tear, or even safety hazards. Based on the high-resolution captures, we provide a detailed analysis, identify potential vulnerabilities, and consult you on appropriate corrective actions.
Particularly for aging installations or in the aftermath of storm damage, this approach represents a highly efficient and safe solution for system testing.
We understand the value of reliability. That is why we treat every installation as if it were our own—ensuring you can rely on your energy supply for the long term.
