The use of solar energy is currently one of the most feasible solutions for electricity production, in the context of European and global policies on reducing carbon emissions. The technology based on the organic Rankine Cycle allows the production of electricity using low-temperature heat sources, being suitable for the production of electricity using solar heat, either directly or by storing solar thermal energy. The paper presents an experimental ORC unit, which produces electricity based on stored solar heat. The experimental unit has been designed for the power of 1 kW and uses the refrigerant R134a as working fluid. The functional scheme and the main equipment used for the construction of the experimental stand are shown. The vaporization and superheating of the R134a vapors is done based on the stored solar heat. The pressure of the superheated vapors at the turbine inlet was between 9–11 bar and the temperature in the range of 53–60 °C. A series of data obtained from the experiments and conclusions are presented.
