Increasing Energy Efficiency Of The Solar Thermal Panels Through The Use Of Hydraulic Tracking Systems

The paper presents some new results obtained by the institute INOE 2000-IHP Bucharest, Romania, in promoting advanced technologies and equipment for solar thermal panel technologies, in order to use the renewable energy resources for individual users. The article presents some results regarding the solar thermal panels, obtained in ROMANIA in the last period, especially in developing of systems used for actuation/guidance automation devices, named solar tracking hydraulic systems, used in the construction of equipment for the conversion of solar energy directly into thermal energy. Also, there are presented some practical hydraulic systems developed in ROMANIA to achieve guidance devices, based on their hydraulic actuation. Finally, the paper presents a new technical solution for a solar tracking system with hydraulic actuation, designed in the institute, which allows optimizing the working regimes, in order to increase the efficiency of collecting the solar energy and its adaptation to the variations of thermal loads during the day. The obtained results can be transferred to industry.
