Logging and photovoltaic (pv) monitoring
We continuously and responsibly monitor and supervise all important parameters of your pv facilities online. These pv monitoring parameters can be:
- Total energy produced during a day, and the total energy stored inside battery pack
- Daily power curve for each pv inverter.
- AC & DC voltages and currents.
- Insulation resistance of pv whole plant.
- Solar radiation, wind speed, ambient and pv frame temperature measurements.
- Public grid status data, such as voltage fluctuations and interruptions.
This data is visualized in graphs, stored in databases and continually evaluated on a daily, monthly, yearly basis to draw safe conclusions about the performance of each plant.
By monitoring pv plants we can achieve:
- Detailed information on the status of your investments.
- Early diagnosis of any malfunction.
- Immediate intervention and correction without delay.
- Maximize generated energy.
- Optimum pv maintenance of investments over time.
- Saving time and costs.

Preventive pv maintenance and inspection of photovoltaic plants
We carry out on-site visual, thermographic and electrolluminance inspection tests of photoboltaic panels. In this way, potential failures can be identified and special measures can be taken. More specifically:
- We perform a detailed digital represantation of the current photovoltaic plant location and then carry out a shading study using modern software methods. This way we accurately determine the energy losses generated and apply different solutions depending on each plant.
- Extensive stability testing of structures. This test ensures resistance to strong winds and avoids the detachment and destruction of equipment.
- Optical check and recovery of corrosion that appears at metal surfaces and joints.
- Check and evaluation of all electrical connections in order to avoid the risk of electric arcs, short circuits and current leaks.
- Inspection for possible defective cells or PID phenomenon, using thermal camera, electroluminance tester and other cutting edge equipment.
- Measuring the performance of all photovoltaic (pv) panels by digitally recording the characteristic current-voltage (I-V curve).
Interventional photovoltaic (pv) support of systems
We are committed to responding immediately and diagnosing any malfunction. We guarantee to fix any damage within 48h, provided that our suppliers have all the necessary spare parts at stock.
Repair of photovoltaic inverters, converters
We take over the diagnosis, repair of faulty inverters and converters from all manufacturers and brands installed in solar park systems, but also in domestic-industrial buildings. Inverter out of warranty either due to lapse of time or due to overvoltage or short circuit and other causes, can get life again and you can benefit instead of buying and waiting for a new device. Specialized technicians in microelectronics inspect the defective inverter and then we inform you about the capability of repairing it at the corresponding cost. Replacing or repairing the faulty electronic board can restore your inverter and keep it functional for a long time. You can send us your request mentioning the manufacturer and type of the defective inverter as well as a brief description of the problem in order to give you a proposal and repair process procedure
