As a result of continuous efforts to improve energy efficiency and growing interest in clean energy, our country has been enriched by new solar power plants, thus expanding domestic solar capacity by a few more “green” megawatts. These investments not only reduce dependence on fossil fuels but also lay the foundations for a sustainable future, creating new opportunities for local economic development.
Solar power plants on the roofs of buildings “Pavilion 1”, “Pavilion 2”, “Pavilion 3” (in preparation) and “Pavilion 4” are a good indicator of how changes can occur. These power plants were realized in accordance with the needs of the investor, Student Center Kragujevac, who recognized the importance of renewable energy. With the support of such and similar projects, Kragujevac joins the cities focused on improving the local energy sector, where each project, regardless of its strength, is a bold step towards sustainable development.
The company CEEFOR, which stands out for its rich experience in the sector of renewable energy sources, was responsible for the realization of the entire project and technical documentation of the student complex. Over the years the company has dealt with a wide range of challenging projects, gaining experience and showing adaptability for designing different solar systems, whether it is ground-based projects or, as was the case this time, on the roof.
Pavilions of the future
The solar power plant on the roof of “Pavilion 1” of the Kragujevac Student Center, with a power of 15 kW AC, was installed with the aim of increasing energy efficiency and the greatest possible energy independence of the facility. 32 photovoltaic panels manufactured by “Luxor Solar”, each with a power of 545 Wp, are installed on the roof. Mounted on the “Chiko” aluminum substructure, the panels are designed to withstand various weather conditions, including winds of up to 60 m/s and snow pressure of up to 1.8 kN/m², which guarantees the longevity of the system. Direct current produced in the panels is converted into alternating current through a 15 kW inverter, manufactured by “Fronius”. Estimates have shown that the power plant will annually produce around 20,809.6 kWh of electricity, while it will save 1.3 tons of CO₂ annually.
A 35 kW AC solar power plant has been installed at “Pavilion 2”, so the specifications differ from the previous case. On the roof of “Pavilion 2” 74 photovoltaic panels manufactured by “Luxor Solar”, individual power of 545 Wp, were installed on the north-west and north-east sides of the roof at an angle of 6°, as well as on the south-west side at an angle of 13°. The system uses two inverters manufactured by “Fronius”, one with a power of 20 kW and the other with a power of 15 kW. It is estimated that this pavilion will reduce CO₂ emissions by 1.2 tons every year, which is a concrete step towards cleaner air and a healthier city.
IN FOCUS:
The construction of a solar power plant with the same output power of 35 kW AC is being prepared for “Pavilion 3”. The power plant will be located on the roof of the third pavilion in a total area of about 186.2 m². It is planned to install 72 photovoltaic panels with an individual power of 570 Wp, also manufactured by “Luxor Solar” as with the previous two power plants. The system will use two “Fronius” inverters, one of 20 kW and the other of 15 kW. It is expected that this facility will annually produce 41,149.2 kWh of electricity, with a projected saving of CO₂ emissions of 1.1 tons.
A 25 kW AC solar power plant was designed at “Pavilion 4”. 49 photovoltaic panels manufactured by “Luxor Solar” were installed, each with a power of 545 Wp. The power plant will use two inverters with a power of 15 kW and 10 kW, also manufactured by “Fronius”. Similar to the others, the annual CO₂ emission saving for this pavilion is estimated at 1.25 tons.
All the electricity produced by the solar power plants of all pavilions will be used to power their own consumers within the facilities, while the excess energy will be placed in the electricity distribution network according to the customer-producer principle.
The CEEFOR company, which was in charge of designing these solar power plants, will continue to develop its vision further, through a series of diverse projects in the future, thus confirming its commitment to sustainable solutions, as well as respecting the principles of environmental responsibility and energy efficiency.
