A new 550 kW solar power plant has been installed on the rooftops of six buildings at the Pančevo Oil Refinery, representing another in a series of projects delivered by MT-KOMEX for NIS a.d. Novi Sad. MT-KOMEX is a leading domestic contractor in the field of solar energy and a pioneer of industrial energy transition in Serbia.
The solar power plant is distributed across approximately 2,720 m² and is installed on six non-production facilities. A total of 1,053 Luxor Solar photovoltaic panels, each with a nominal output of 580 Wp, generate electricity primarily for the refinery’s own consumption, while surplus energy is fed into NIS’s closed distribution system under the prosumer (buyer–producer) model.
Special attention was given to ensuring system reliability under demanding industrial conditions. The installation of 13 Huawei inverters with a total nominal capacity of 300 kW, along with 527 optimizers, ensures high efficiency of each solar string, even in conditions of partial shading. The system includes DC and AC distribution cabinets, cable junction boxes, and a SMART Logger system, enabling advanced real-time management and monitoring.

As the project contractor, MT-KOMEX once again applied its proven technical solutions—from precise planning of panel layouts on both flat and pitched rooftops to the integration of the solar power plant with the medium-voltage network of the closed distribution system at the 6 kV level, which supplies the entire refinery.
With the construction of this new solar power plant in Pančevo, NIS further strengthens the use of renewable energy sources within its facilities, while MT-KOMEX confirms its position as a company that continuously raises standards in the solar energy sector and delivers new benchmark projects in industrial environments. Once again, it is demonstrated that the transition to cleaner and more secure energy is built—panel by panel.
