The Energy Hat-Trick


How to introduce energy efficiency, mitigate carbon footprint and reduce electricity bills? And can it be achieved at a single blow? This triple benefit is possible to attain by building the solar power plant. Since Serbia has excellent potential for electricity production from solar radiation and thanks to recently adopted laws in the energy sector, people frequently consider how to use this solar capital.

The idea of solar power plant construction is entertained by big companies and citizens, who have now gotten a chance to become prosumers. That means they will leave their usual role as electricity buyers and take on the new part of energy producers. There are many benefits of using renewable energy resources. The following might be the shortest and simplest explanation that Miloš Kostić offered. He is the manager of the MT-KOMEX company, which has been building solar power plants in Serbia for ten years.

“When we install a solar power plant on a roof, we have an opportunity to consume the energy we produce and to reduce the amount of energy we take directly from the grid. That way, the savings are made because all expenses incurred by energy transport are eliminated. In addition, the users gain independence from their suppliers. At the same time, the carbon emissions are reduced as well as the amount on electricity bills. Finally, the awareness on environmental protection is being raised”, notes Kostić.

Guided by these principles, the heads of the Stojanov and Stojanov Auto companies from Novi Sad decided to install solar power plants on the roof of their facilities. They wanted to provide for electricity supply in an ecological, efficient, and cheap way. Thus, in April this year, three solar power plants were commissioned, whose total capacity is 225.3 kW. To implement this project, they relied on the MT-KOMEX company. This enterprise has been in this business for more than 25 years. In its portfolio, it has more than 40 solar power plants constructed in Serbia, among other projects. The construction on the Renault-Nissan facility took four days. Some 168 photovoltaic panels were installed, with 330 W of individual capacity, all coming from the German company Luxor Solar. The installed capacity is 55.44 kW, while the active power is 50 kW. In addition, the inverters with 20 and 10 kW capacities were installed. The company that made them is the Austrian manufacturer Fronius. For the substructure for all three facilities, the German company K2 was selected, and their special substructure type Multi Rail. This power plant will generate approximately 64,472 kWh a year, making around 30,267 kg of CO2 savings a year.

One hundred fifty-six photovoltaic panels were installed on the JEEP facility, with 30 W of individual capacity, coming from the same supplier Luxor Solar. The installed capacity is 51.48 kW, while the active power is 45 kW. Forthis power plant, the Fronius inverters were chosen with 20, 15, and 10 kW capacity. According to the plan, the solar power plant was built in four days. The annual production of this power plant will be around 61,366 kW, and CO2 yearly savings will reach 28,823 kg.

On the third FIAT facility, 320 photovoltaic panels were installed with a singular capacity of 370 W, produced by the Canadian Solar company. The installed capacity is 117.40kW, while the active power is 100kW. The engineers here decided to stick with checked inverters from the Austrian producer Fronius, whose capacity is 20 kW. The solar power plant on the FIAT facility will generate approximately 139,106 kWh a year. It will also make annual savings up to 111,235 kg CO2. It took seven days to build this power plant.

The MT-KOMEX company team isn’t only engaged in solar power plant construction. They have expanded their business to the development of e-mobility. Their experts have installed more than 200 EV chargers around the country so far. In addition to that, they constructed several solar canopies so that energy for EV charging could partially come from renewable energy resources. As leaders of e-mobility in our country, it doesn’t seem unusual that they launched the first regional platform charge&GO for billing the use of parking lots for EV charging. Thanks to this platform and mobile application, the owners of electric vehicles can find chargers fast and easily in Serbia and more than 30 countries worldwide. Furthermore, it is essential to say that there is no additional roaming expense for using the chargers in our partner’s network. At the very end, let’s get back to the beginning of this story. The electricity bills are higher year after year, and solar energy isn’t something we lack across this land.

Do you find it is about time you took advantage so that the solar power plant on your roof could work for you?
