During the first half of 2023, photovoltaic panels
were also installed on the roofs of the heat exchanger stations by Prvá
teplárenská in Holíč. The company uses them in the process of heat and hot
water supply. Preparations are already underway at Slovarm for photovoltaic
installations on the roofs of buildings. They should provide electricity for
the plant’s own consumption and mitigate the impact of high electricity prices.
Work is also underway to prepare for further
installations on the buildings of other companies in the Group, taking into
account a number of factors such as the technical options of placement, the
load-bearing capacity of the roofs, the placement of downstream technologies,
the impact of the environment and various obstacles, the usability of the
energy generated, the immediate consumption, the possibility of storing it, and
the return on investment.
Solar energy is one of the cleanest and
most affordable forms of renewable energy. The Earth receives a large amount of
solar radiation which can be used to generate electricity or heat. In our latitudes, the annual average of solar
radiation is about 1,100 kWh/m2, which means that an area of
1 m2 receives as much energy per year as an average Slovak
household would consume in 3 months.
The potential of solar energy is currently untapped.
According to the studies carried out, it would be possible to cover a
significant part of the total electricity consumption with photovoltaics.
However, in the current situation in Slovakia, the process of updating the
legislation for supporting the expansion of renewable energy sources,
especially in the field of energy communities, is somewhat delayed. It would facilitate
the use and sharing of the produced energy, therefore it is important to take
into account all the input factors in order to make the operation of such a
source really efficient.
