Photovoltaic system maintenance and professional inspections

Regular maintenance and professional inspections of photovoltaic systems are essential for ensuring safety, maximizing efficiency, and preventing costly repairs. While cleaning panels can be done by owners, professional technical inspections are required to assess cabling, electrical connections, protective elements, and inverters.

Professional inspections help identify hidden defects such as poor insulation or loose contacts, which can reduce system performance by up to 20%. Some services also include thermal imaging to detect overheating joints. Furthermore, regular maintenance may be a prerequisite for maintaining manufacturer warranties or insurance validity.

Initial inspections must be conducted before a system is commissioned to ensure the installation meets safety standards and project documentation. Subsequent periodic checks, such as alternating between general inspections and electrical revisions, help mitigate risks of overheating and fire.
