Thanks to ongoing efforts to enhance energy efficiency and the growing interest in clean energy, new solar power plants have enriched Serbia, further expanding its solar capacity with additional green megawatts. These investments reduce dependence on fossil fuels and lay the foundation for a sustainable future, creating new opportunities for local economic development.
Solar power plants on the rooftops of Pavilion 1, Pavilion 2, Pavilion 3 (in preparation), and Pavilion 4 serve as an excellent example of how change can be initiated. These plants were implemented based on the investor’s needs, the Student Center Kragujevac, which recognized the importance of renewable energy. With the support of these and similar projects, Kragujevac is joining cities focused on improving the local energy sector, where every project, regardless of its scale, is a bold step toward sustainable development.
The comprehensive technical and project documentation for the student complex was handled by CEEFOR, a company renowned for its extensive experience in the renewable energy sector. Over the years, CEEFOR has tackled a wide range of challenging projects, demonstrating adaptability in designing various solar systems, whether for ground-mounted installations or, as in this case, rooftop projects.
Pavilions of the Future
The solar power plant on the rooftop of Pavilion 1 at the Student Center Kragujevac, with a capacity of 15 kW AC, was installed to increase energy efficiency and the energy independence of the building. The roof houses 32 photovoltaic panels from Luxor Solar, each with a power output of 545 Wp. Mounted on an aluminum substructure by Chiko, the panels are designed to withstand diverse weather conditions, including winds up to 60 m/s and snow loads of up to 1.8 kN/m², ensuring system durability. The DC electricity generated by the panels is converted into AC by a 15 kW Fronius inverter. The plant is expected to produce approximately 20,809.6 kWh of electricity annually and save 1.3 tons of CO2 annually.
On Pavilion 2, a solar power plant with a capacity of 35 kW AC has been installed, resulting in different specifications compared to the first pavilion. The roof of Pavilion 2 features 74 photovoltaic panels from Luxor Solar, each with a power output of 545 Wp, arranged on the northwest and northeast sides of the roof at a 6° angle and on the southwest side at a 13° angle. The system utilizes two Fronius inverters, one with a capacity of 20 kW and the other with 15 kW. It is estimated that this pavilion will annually reduce CO2 emissions by 1.2 tons, a tangible step toward cleaner air and a healthier city.
IN FOCUS:
- Green Projects – TENT A Gets A Solar Power Plant
- Alternative Fuels – the EU’s Path to Climate Neutrality
- Ecological Vision – Good Health of People and Nature
For Pavilion 3, a solar power plant with the same output capacity of 35 kW AC is in preparation. The plant will cover a total area of approximately 186.2 m² on the roof of the third pavilion. It is planned to install 72 photovoltaic panels, each with a power output of 570 Wp, again from Luxor Solar, as in the previous cases. The system will use two Fronius inverters, one with a capacity of 20 kW and the other with 15 kW. The facility is expected to produce 41,149.2 kWh of electricity annually, with a projected CO2 savings of 1.1 tons.
On Pavilion 4, a solar power plant with a capacity of 25 kW AC has been designed. The roof has 49 photovoltaic panels from Luxor Solar, each with a power output of 545 Wp. The plant will use two inverters: a 15 kW and a 10 kW model, both manufactured by Fronius. Similar to the other pavilions, the estimated annual CO2 savings for this pavilion are 1.25 tons.
All electricity generated by the solar power plants on these pavilions will power their internal systems, with any excess energy supplied to the distribution grid following the prosumer model.
CEEFOR, responsible for designing these solar power plants, will continue to advance its vision through a series of diverse projects in the future, reaffirming its commitment to sustainable solutions and adherence to the principles of environmental responsibility and energy efficiency.
