Czech utility group ČEZ is using the new photovoltaic power plant in Ledvice to test the properties and suitability of various types of panels that it wants to deploy, following the assessment, in large solar parks that the company is planning.
It is the most modern traditional power plant in Central Europe the solar panels’ capacity is a mere 56.6 kilowatts (kW) but they clearly differ from one another at first sight in terms of type, cardinal direction orientation, or degree of incline. New technologies are represented, such as double glass and double facial, enabling the use of light coming from both sides, but also high-efficiency types such as Half cut and PERC, which generate power even if partially shaded or in the case of pollution. And also the increasingly popular agrivoltaic is represented – unusual vertical panels suitable for combining power generation with agriculture and pasturage.
The aggregate capacity of these sources, which will contribute to the achievement of the Czech Republic’s climate goals and commitments, should reach tens of thousands of megawatts (MW) in the next 10 years.
“The efficiency of panels has shot up from 13 to 20 per cent in the last decade; so, photovoltaic certainly has a great potential,” said Jan Kalina, CEO OF ČEZ Obnovitelné zdroje. “But we want to be 100 per cent sure that our large power plants for the next decade, with aggregate capacity in the order of thousands of megawatts, will be composed optimally and will have the ideal price/performance ratio. That is why we are testing various types of technologies and load-bearing structures in one locale and are conducting comprehensive monitoring of their operation. We analyse them down to the level of manufacture of individual panels, in combination with values of sun exposure, the temperature of the panels and their surroundings, or wind speed. The outcome will be a specific recommendation for the construction of large solar parks.”
This spring, the first large power plant using solar power, located on the roof of the Dukovany Nuclear Power Plant parking lot, will start supplying emissions-free power to the grid. Also, the largest solar installation in the last ten years, with a capacity of 2.3 megawatts-peak (MWp), will be built on the roofs of the automobile manufacturer Škoda Auto by ČEZ ESCO.
In the Czech Republic, the ČEZ Group currently operates photovoltaic power plants with an aggregate capacity of 125 MW, which produce power for approximately 40,000 Czech households every year, depending on the natural conditions.
