In June, the repowering project in the city of Gotha, Germany, reached its successful conclusion. This project, originally installed in 2012, involved a photovoltaic system with the capacity of 11.7 MWp, comprising of more than 50,000 panels of various capacities. The primary challenge we faced was finding a solution for dismantling the old glass panels, which weighed tens of kilograms each and could not be handled manually like today's conventional panels.

Ultimately, we devised an efficient method using a suction cup attached to a robotic arm. This device securely clamped and disconnected the panel, transferring it to a specially prepared structure mounted on the forks of a wheel loader. The wheel loader then transported the panels to the designated container. This solution proved to be the most effective for the safe dismantling of the old glass panels.

With this obstacle overcome, we could focus on optimizing the synchronization of various activities to achieve maximum efficiency. As part of our planned repowering efforts, following the successful dismantling of the older panels, our Greenbuddies installation teams installed nearly 22,000 new panels, each with a capacity of 545 Wp to approximately two-thirds of the existing mounting structure. The whole power plant also needed a complete restringing to accommodate the new panels.

The completion of the project in Gotha marks an important milestone in the repowering and revamping activities of our Greenbuddies team. By replacing outdated panels with modern, high-capacity ones, the efficiency and performance of this photovoltaic system were significantly enhanced and the longetivity of this infractructure was ensured.
