AIDI SOLAR, using analytical software developed by prominent Ukrainian mathematicians and IT specialists, has already checked 360 MW of the installation since 2019, which brought 5,254,203 kWh energy savings annually and allowed to replace 15,429 damaged photovoltaic panels in UKRAINE with new ones.
We are currently at the stage of introducing our software in Poland as AIDI SOLAR POLSKA with the use of financial support from the Lublin Science and Technology Park as part of the "Connect Poland Prize" project.
In our opinion, it is one of the best tools of this type on the European market. It allows for a very high accuracy of detection of 8 different errors, after elimination of which the efficiency of the PV installation increases to nominal values and allows for additional power yields.
AIDI SOLAR POLSKA offers a modern service of inspection and thermal imaging of panels and photovoltaic installation using drones, i.e. a thermal imaging study using unique software based on an advanced mathematical algorithm of artificial intelligence AI.
It is worth emphasizing that the offered thermovision inspection with the use of drones is also an element of risk management used by investment funds, banks and insurance companies. On the other hand, it can also be useful for owners of a photovoltaic installation to submit complaints about modules or other components.
Photovoltaic panels, although practically maintenance-free, require periodic inspection – once a year in order to eliminate faults and defects.
Module defects, if not detected, can result in loss of revenue of up to 20% - that is why it is so important to regularly check the condition of the photovoltaic installation.
Diagnostics with "self-learning", AI-based analytical software - this is the only effective way to systematically and precisely review, monitor, necessary to maintain modules and installations in the highest efficiency for many years.
Thermal inspection of photovoltaic panels with drones is more effective than traditional thermal inspection from the ground, unlike regular inspection where engineers analyze thermal images for several days, drone inspection is done in a single flight, using analytical software enabling almost instant, highly - precise algorithmic diagnostics, saving costs. Not only is the time shortened from a few hours to several dozen minutes, but everything is fully automated. Once the faults are removed, the efficiency and energy yield will return to nominal values and will increase revenues and faster return on investment.
Due to the constantly growing number of PV installations in Poland, it is extremely important to get it right and professional approach to their reviews.
THERMAL INSPECTION REPORTS WITH DRONE
In our report, each defect is identified to the row, module and has an assigned detection history, and an individualized report, created for the purposes of efficient installation management, accelerates diagnostics and enables precise maintenance reducing losses related to incorrect operation of the installation, lost production, and thus goes on earnings.
The report includes the most frequently detected defects in eight categories at the level of:
• diodes - refers to the detection of failure of the diodes themselves;
• string - for localization of a chain of disabled modules, as well as damage to fuses;
• hotspots - detection of hot spots with increased resistance in which too high temperatures are generated, which can lead to burning holes in the back layer of the foil, and in consequence, even to a fire. Hotspots are often caused by microcracks and partial shading;
• reverse polarity - finding reverse currents, such as current flows from the good strings to the damaged ones, instead of flowing into the PV converter and supplying power to the AC mains;
• PID - locating the degradation with induced voltage, i.e. losses arising in the power generated by the photovoltaic installation as a result of the potential difference between the semiconductors contained in the cells and the aluminum, grounded frame of the modules with zero voltage;
• dirt - detection of dirt, such as: mud, dust, bird droppings that are the cause of shadows;
• shading - location of permanent or periodic shading spots and hotspots, causing a decrease in energy yield from the photovoltaic installation;
• vegetation - determining the greatest potential of solar energy in the operation of panels, taking into account the influence of plants (including needles and leaves);
All the collected and processed information is immediately displayed in the report interface, also as a thermal map, so that you can easily comprehensively review and read all the key parameters of the status of the monitored installation. The analysis of the collected data from the report has a significant impact on the efficient operation of the entire installation and directly on the level of revenues from investments.
