Photovoltaic plant inspection

Why should every PV plant be checked regularly?

According to IEC 62446-3, the regular inspection and maintenance of photovoltaic systems (PV plants) is required for commercial users. We are certified thermographers and licensed commercial drone pilots. After obtaining the required permissions to perform the drone examination we create complete test reports and supply original photo and video data for your further use.

We carry out inspections on PV plants of all sizes, both on land, water and roof tops. We check quickly and safely using a drone with a high-resolution thermal imaging camera (640×512 px). During the examination, various defects (e.g. „hot spots“ or „substring failures“) can be detected at individual connection points, which are not noticeable in other examinations due to their small size, but which have a decisive impact on the entire string connected to the module. Does defects not only will reduce the revenue the PV Systems is generating, but also can eventually cause larger problems that could in the worst case lead to a fire of the PV module.

We are certified thermographers and have up-to-date camera technology as well as evaluation software, combined with many years of experience on many diverse PV Systems with various project scopes.

Regular inspections maintain the safety and performance of the PV system and ensure early detection of warranty damages or damages that covered by insurance.

When should an inspection take place?

A thermographic examination of your PV system should take place at the following times:

• shortly after commissioning of the PV system
• before the warranty on installation expires
• before the manufacturer’s product liability expires (guarantee against mechanical damage, usually 10 years)
• before the manufacturer’s guarantee on the performance of the system expires
• when system yield decreases and a failure is suspected
• after severe weather events in the proximity of the PV System (e.g. lightning strikes, hailstorms, flooding after heavy monsoon storms, heavy thunderstorms, etc.) to detect potential damages and subsequently claim insurance benefits

IEC 62446-3 even recommends routine inspection of PV plants using thermography every 4 years.
