Photovoltaic panels on city buildings in Trnava

Today, primary schools in Trnava are largely self-sufficient in the production of electricity. There are photovoltaic panels on the buildings of nine primary schools under the authority of the city, which significantly contributed to the reduction of electricity bills. Trnava was the first city in Slovakia to take such a step. The installation of photovoltaic panels on the roofs of elementary schools began in the fall of 2022. In February, all of them were already producing their own energy, while two of them were able to produce a surplus. More were added gradually. In addition to elementary schools, there are two other buildings equipped with photovoltaics, namely the Social Care Center on Vladimíra Clementis Street and the city polyclinic on Starohájska. The price of photovoltaic panels was 862,918.80 euros including VAT. The expected payback is in the range of three to four years, but depends on several circumstances, especially energy prices. The municipality received a non-refundable financial contribution of 91,913 euros for the construction of a photovoltaic power plant in the Social Care Center in Trnava, at 51 Vladimíra Clementis Street. However, after more than half a year of operation, the numbers show that photovoltaics has its justification. From a long-term perspective, the estimated average saving of electricity per school is 67 percent. In the spirit of the motto "Energy for free and forever", the city wants to continue with the introduction of photovoltaic systems on other of its buildings. Such a system would significantly help, for example, the winter stadium, which already indirectly benefits from the aforementioned photovoltaic panels at elementary schools. They were able to produce more electricity than they consume. The surplus of electricity therefore went to the distribution network, and thanks to this, the winter stadium's payment for electricity was reduced in April. The new program period will also be devoted to energy, which is why we want to prepare projects for a large number of buildings owned by the city by then. In addition to the winter stadium, in the near future, the establishment of photovoltaics is also being prepared at the building of the Seniors' Facility in Trnava on T. Vansová and at the renewed construction of the municipal waste dump on Zavarská cesta. At the same time, the capacities of photovoltaic panels will be increased to the maximum allowed in all primary schools.
