The renewable energy sector is entering a phase in which technical maintenance becomes a strategic resource. The rising capacity in the Balkans requires new approaches regarding the reliability of photovoltaic systems. The data shows that close to 70% of malfunctions in PV parks are due to hidden defects – overheated cells, damaged connectors or degradation in the material. These are the aspects that are unnoticeable during standard visuals inspections, and judging by the analysis, are responsible for the loss of between 3 to 8 percent of the yearly yield. This dynamic is also creating a new standard – thermographic analysis. It allows operators to manage systems using real-time data, rather than preventative maintenance schedules. In Europe, thermography is now considered a key tool for preventive diagnostics and yield optimization.

For a company like Filkab Solar, which has over 30 years experience in the energy sector and a focus on solar technology for the last decade, integrating thermography is a logical next step. In addition to being a distributor of components, the company positions itself as an engineering partner – from design and delivery to maintenance and optimization. This model reflects the new philosophy of the sector - energy is now measured in data and reliability.

"Solar system maintenance is increasingly shifting from 'fault response' to continuous analysis of system behavior," Filkab Solar commented. Thermography allows for early detection of anomalies in the operation of modules and more precise planning of service interventions, which is the basis for stable yield and the extension of the service life of the panels.

According to good engineering practice, thermographic monitoring is more economically justified for installations over 200 kW, but it is increasingly being used for corporate rooftop systems. The reason is simple - every hour a panel operates below its optimum temperature is an hour of lost energy - and missed returns.
