Why photovoltaics?

  • The construction of the Radkovy photovoltaic power plant reference building within the expansion of Amsoft services to include the sphere of photovoltaic system supply
  • Because the general scope of Amsoft is electronics, photovoltaics is a related field falling into the sphere of activity of the company
  • Work with the latest Hi-Tech technology
  • Long-term investment with a relatively high level of security
  • Contribution to the struggle against global warming and improvement of the environment Slunce.jpg, 10kB
  • Preparation of a legacy for future generations
  • Electricity generated using solar systems is the cleanest energy man is able to generate. It doesn't produce noise, like wind power plants do and, last but not least, it doesn't need complicated maintenance like hydroelectric power stations or nuclear energy. During their c. thirty-year working life, photovoltaic systems require minimum maintenance. The power plant produces no dangerous waste during operation
  • The solar power plant constructed using the state-of-the-art technologies represents a highly prestigious matter for the investor, supplier, community and the region. By supporting the project, the involved parties endorse the globally shared values of environmental protection

Brief description of the solution:

  • Electricity is generated using 1,170 Suntech photovoltaic panels, type STP 180S-24/Ad with an output of 180 W, installed to increase the total revenue on 43 adjustable single-axis frames of our own construction (tracks) with an automatic sun movement tracking system. The frames are equipped with a PLC Mitsubishi central controlling system which, along with exposure sensors, ensures optimum alignment towards the sun. The conversion from DC to AC is solved using a corresponding number of type SMC 8000 Tl ESS inverters in decentralized configuration. For comparison of power generation, a fixed frame with 52 panels and one SMC 8000 Tl ESS inverter has been installed in the premises of the power plant.
  • The power plant is connected to a distribution system via the measurement of drawn energy and a substation.
  • The controlling system of the power plant enables remote supervision, visualization, monitoring and archiving of service data and archiving of possible failure states.
  • The whole power plant property is fenced and equipped with a basic alarm and camera system.
  • The power plant is expected to operate all year round, unmanned.
  • Expected service life is 30 years.
