If we maintain our current standard of living, this will have an immediate impact on the global climate and will result in a temperature increase of up to 3.9 ° C by the end of the century. Due to the Paris climate agreement of 2015, 197 parties have already set a common goal to stay below the specified 2 ° C limit. However, this action plan in the fight against global warming is not enough to ensure future generations survive on this planet. Energy production also plays an important role in the areas of our society that need improvement. A necessary step, for instance, the switch from coal-based energy generation to renewable solutions such as photovoltaic systems or wind farms.


Especially regarding PV systems, the individual solar cells and storage units for the energy gained are becoming increasingly powerful. Ohio State University is also currently researching an integrated battery within the cells. As a result, the energy gained from the sun can be transferred directly from the solar cell to an external battery without loss.


People who inspect a solar panel

Complex inspection very easy - a revolution from the air

Not only the storage of energy but also the maintenance of the used system is constantly evolving. Thanks to the use of drone technology, regular and smooth inspection of energy generation systems is no longer a problem. Conventional methods for maintaining and inspecting solar systems, wind farms and bridges are time-consuming moreover there is an increased risk of injury for the specialists involved.

Drones are just as helpful when inspecting photovoltaic systems. The cumbersome inspection by technicians, who only get a view of the system from above with a lifting platform, is made considerably easier with the help of flight thermography. This process enables operators of the solar parks to obtain information about the condition of the individual solar cells in the shortest possible time and to renew them if necessary, to obtain sustainable energy more efficiently.


FairFleet’s approach to fighting against climate change

As a full-service drone solutions provider, we use our know-how to facilitate the generation of green energy. Using drone technology, anomalies in each solar panel can be easily identified from the air.

We inspect photovoltaic systems worldwide. The largest project to date took place in collaboration with Raptor Maps in Mexico. The 7.93 square kilometers photovoltaic system has an output of 400 megawatts and can supply 50,000 households with electricity. For comparison: The entire city of Cottbus could only be supplied with energy from this one solar system if an average two-person household is assumed. Such huge areas with a size of around 1100 soccer fields are almost impossible to inspect from the ground. Thanks to our drone pv inspection, we were able to fly the entire system within just 10 days. These inspection flights like all others are planned by FairFleet in-house so that the flight is carried out completely autonomously and saves resources and only must be interrupted to change the drone's battery.

Based on the recording’s hot cells, for example, can be recognized during the evaluation and rectified as quickly as possible to avoid consequential damage and ultimately to increase the yield. A problem that arises when one cell is defective and acts as a resistor for the current flow of the other cells. In general, various solar cells are combined in modules that are in turn connected in strings in a row and conduct the electricity obtained to the generator. By connecting them, the defective solar cell heats up due to the current of the other cells continuing to flow until it ultimately makes the entire module unusable and can start a fire. For this reason, a regular inspection is necessary to identify defects at an early stage and to prevent possible damage.

We can count companies such as Renerco Plan Consult among our partners. Due to their specialist knowledge in the solar industry complementary cooperation arises from the know-how of drone services and that of the solar industry. Our goal in the future is to be the number one contact person for the needs of a company. In general, we want to be the drone service provider with whom you can enjoy the entire cycle from planning and measuring the upcoming project with documentation of the construction progress to regular inspections of the finished system with possible marketing recordings.
