            Solutions for renewable energy

            Renewable energy

            Whether they provide photovoltaic, wind or water power, the number of power generation plants using renewable energy continues to grow. The operators of these plants attach great importance to efficiency and economy. Only by means of proper system solutions for the control and monitoring of power generation can competitive efficiency be achieved. Only a high level of efficiency can create the economic basis for replacing electricity from fossil fuels. In addition, it is important that safety-related issues are considered.
