Increased living standards in the developed countries lead to increased energy consumption. By using renewable energy, the fossil fuel consumption and greenhouse gas effect are reduced. The main source of renewable energy is the sun that can be used to produce the thermal energy or electric energy. The concentrating collectors are used to obtain both heat and electricity. The most common and used concentrating collectors are the parabolic trough collectors due to their advantages, such as: lower price, use of mono-axial tracking systems, simple maintenance. Parabolic trough collectors can have orientation around the N-S axis or E-W axis. In the case of N-S orientation, the angular stroke is higher than 120°, and in case of E-W orientation, the angular stroke that the tracking system has to ensure is less than 100°. The mechanisms used to orientate these collectors are using gears, cam or chain transmission. The paper presents a new type of mono-axial tracking system with linear actuators that has the advantages of assuring the required angular stroke, a high orientation accuracy and lower price.
