On the roof of the business building of the sawmill in the Karlovac Business Park, an integrated photovoltaic power plant with a capacity of 112.50 kWp (output power of 70 kW) has been installed. The installation utilizes photovoltaic modules to generate clean energy with an annual capacity of 108,418.51 kWh. Most of the generated energy is used for the needs of the sawmill, while the surplus of 21.764 MWh is fed into the grid. The power plant has been designed with an emphasis on safety and efficiency, including lightning protection systems, surge protection, as well as occupational safety and fire protection measures. This project represents a step towards a sustainable future, promoting renewable energy sources and environmental responsibility, thus reducing CO2 emissions and contributing to a cleaner environment.
