Our Services

Wesii’s Elios Analytics offers a profound and valuable analysis service for the PV plant owners. Our services allows to deliver to the client a series of tools that help to identify defects which may compromise the correct functioning of the panels and classify them, and therefore keep the assets under constant supervision and take action wherever and whenever needed.
Wesii is currently able to automate the procedure of the serial number identification within each module of the PV plant asset and lower down its actual costs. This operation is possible thanks to high definition (0.1mm/px) sensors positioned on drones during each flight. We also extract the requested information and meticulously catalogue it. All the serial numbers are automatically uploaded onto our web portal as an addition to the complete thermographic report.
The high resolution utilised to identify serial numbers is also very useful to perform a precise visual inspection of the PV panels. This kind of analysis had been usually carried out at ground level by using handheld devices to measure each and every module’s performance. Our services offer a faster and more accurate approach: thanks to the drone technology we can collect and analyse data faster and make it all happen remotely from PC.
