Solar panel inspection, keep your panels in top shape

Solar panel inspection

Want to be sure your solar panels are performing optimally and are free of hidden defects? With a solar panel inspection not only gives you insight into the current state of your installation, but also prevents unexpected breakdowns and loss of efficiency. At Solarco, we scrutinise every aspect of your system, so you can have peace of mind that your energy production is efficient and safe.

Why is a solar panel inspection so important?

Solar modules are exposed to all kinds of influences throughout the year: from strong sunlight and high temperatures to storms, rain and temperature changes. Over time, these conditions can lead to wear and tear or minor defects that you don't always see with the naked eye. Think of microcracks in the panels, loose wiring or heat damage (hotspots).

A thorough inspection helps you detect and address these problems early on. As a result, you will continuously benefit from high yields and extend the life of your panels. Moreover, properly functioning solar panels contribute to the safety of your home or business premises, as the risk of short circuits or fire hazards is minimised.

How often is a solar panel inspection needed?

Most experts recommend having your solar system checked at least once every two years. In certain cases, for example if you live in an area with a lot of dust, salt (near the sea) or heavy industry, an annual check may be desirable. It is also wise to have an extra inspection of your panels after extreme weather conditions, such as heavy hailstorms or storms.

At Solarco, we work with tailor-made inspection plans. Together with you, we determine the ideal frequency, based on factors such as the age of the installation, its location and any local risks. This way, you always maintain an optimal return and reduce the risk of unexpected problems.

How do we proceed at Solarco?

Visual inspection

We start every solar panel inspection with a careful visual check. Here, we pay attention to cracks in the glass, the condition of the frames and any discolouration or distortion. We also look at the fixings, clamps and cable entries, to make sure everything is still firmly in place.

Measurements and tests

Besides the visual check, we perform several measurements to make sure your system is functioning properly. These include measuring the DC voltage, checking the inverter and reading fault codes. This way, we detect possible anomalies at an early stage and can provide targeted advice.

Thermographic inspection (optional)

For an even deeper investigation, we deploy thermographic cameras. With this technology, we detect so-called hotspots on parts of a panel that become hotter than the rest. This can indicate damage, contamination or faulty cells. Thanks to the thermal images, you can immediately see if there are any spots where yield losses are occurring or where there could even be a fire hazard over time.

Thermographic Inspection

Using drones or handheld thermographic cameras, we detect hotspots, defective cells and other irregularities early. This prevents dangerous situations and helps you maintain the efficiency of your solar panels.

General inspection

During a general inspection, we check the entire installation, from panel to cable. You receive a clear report with recommendations, so you know exactly what steps are needed to keep your system 100% operational.

Benefits of a professional solar panel inspection

Optimal performance: A thorough check prevents loss of efficiency and allows timely intervention.
Longer lifespan: By spotting small defects early, you prevent bigger damage and extend the life of your panels.
Security: An inspection reduces the risk of short circuits or fire hazards, giving extra peace of mind.
Warranty retention: Many manufacturers and insurers make periodic checks mandatory to claim warranty or coverage.
Sustainable investment: With a well-functioning system, you get the most out of your investment and contribute to a green future.

Frequently asked questions about solar panel inspection

A superficial check is of course possible, but an in-depth check of cables, inverters and panels requires professional knowledge and equipment. That way, you can be sure you won't overlook any essential issues.

It depends on the size and accessibility of the installation. An inspection can often be completed within a few hours, including a report.

Thermographic inspection is an additional tool to detect invisible hotspots or faulty cells. We recommend it especially for larger installations or when a malfunction is suspected.

If possible, we carry out minor repairs immediately. For larger problems, we make clear agreements on the parts needed and schedule, so that you can quickly benefit from an optimally functioning system again.
