Photovoltaic farms are covering an increasing area of our country and are therefore much more often located in areas that are difficult to access. The delivery of lightweight components does not cause problems for contractors, while heavy transformer stations can become a challenge. Components weighing several tonnes have to arrive on site and then be unloaded and installed. As an example of our contribution to the development of clean energy, another successful implementation. Within 72 hours of our first contact with the customer, we arrived at the site of the work in Lubuskie. We started the installation of an access road of almost 400mb for the delivery of 4 transformer stations, which took 2 working days in adverse conditions. On site, we found a partly constructed road made of reinforced concrete slabs, which our client had finally abandoned, relying on our experience. This solution enabled a safe access to be made quickly and efficiently and, importantly, the transformer stations arrived on schedule.
