Solar Panel Inspection and Maintenance

Following the preventative inspection, you will receive a clear report setting out our findings and recommendations. It will detail exactly what steps are required to keep your system running optimally and securely, and whether corrective maintenance is advisable.

Yes. If any faults are identified during the inspection or thermographic survey, we don’t just stop at a report. We tackle the identified problems head-on – from loose cabling to damaged parts – so that you don’t have to look for another provider yourself.

Using thermographic cameras – either drone-mounted or handheld – we visualise temperature differences in your panels. This enables us to detect hotspots, faulty cells and dirt that are invisible to the naked eye. This prevents a loss of efficiency and dangerous situations in the long term.

Most experts recommend at least one inspection every two years. In areas with high levels of dust, salt or heavy industry, or following extreme weather conditions such as storms and hail, an annual inspection may be advisable. Together, we’ll draw up a bespoke plan based on the age, location and risks associated with your installation.

Preventative maintenance involves inspections and thermographic surveys, which we use to assess the condition of your system and identify problems at an early stage. Corrective maintenance is only carried out if defects are found; in that case, we carry out the necessary repairs. This way, we only intervene where it is really necessary.

Contamination disturbs thermographic and electrical measurements and can mask real defects, which is why: clean first, then measure, then decide. Clean panels are thus a prerequisite for a reliable inspection. This way, you avoid wrong conclusions about the true condition of the installation.

Yes, Solarco provides professional maintenance and cleaning for commercial roofs, farms, industrial plants and solar parks, with cleaning robots for large areas. We combine cleaning with thermographic inspection and green management, and work VCA-certified. For recurrent maintenance, we draw up a tailor-made contract.

After 5 to 10 years, outdated cabling and connectors often turn up, loose terminals and profiles, and microcracks, delamination and hotspots in the modules. Untreated, these lead to structural efficiency losses, recurrent inverter failures and increased fire and safety risks. A combination of visual, thermographic and electrical checks detects them in time.

Maintenance includes a visual inspection for damage, loose wiring, broken terminals and hotspots, complemented by measurements and tests of the inverter and yield data, among others. In addition, green maintenance, such as mowing between panel rows, is included in the service. Regular maintenance extends lifespan, increases safety and helps maintain the manufacturer's warranty.

Even a small shadow can noticeably reduce efficiency, with overgrowth around and between the panels affecting yields. Overgrowth also hinders access for maintenance and can increase fire and damage risks. That's why Solarco keeps grass and weeds short, ecologically responsible and with a report after each visit.
