Various mechanical, hydraulic, pneumatic, electrical, and hybrid actuators can alter motion per the requirements of particular applications. However, except for electrical ones, all actuators are restricted due to their size, complex auxiliary equipment, frequent need for maintenance, and sluggish environment in renewable applications. This brief review paper highlights some unique and significant research works on applying electrical actuators to renewable applications. Four renewable energy resources, i.e., solar, wind, bio-energy, and geothermal energy, are considered to review electric actuators applicable to renewable energy systems. This review analyses the types of actuators associated with the mentioned renewable application, their functioning, their motion type, present use, advantages, disadvantages, and operational problems. The information gathered in this paper may open up new ways of optimization opportunities and control challenges in electrical actuators, thereby making more efficient systems. Furthermore, some energy-efficient and cost-effective replacements of convectional actuators with new innovative ones are suggested. This work aims to benefit scientists and new entrants working on actuators in renewable energy systems.

The tracking system that uses for PV solar systems has a vital role to improve the energy performance of the solar panel. In the present study, the performance of both the fixed PV solar system and single -axis tracking PV solar system is investigated experimentally. The power for each PV solar panel is 150 W. The performances of the two systems are compared to display the efficient improvement of a single-axis solar tracking (SAST) system with fixed solar (FS) system under the climate conditions in the Zakho/ Kurdistan region/ Iraq. A mechanical tracking device with a controller and linear actuator was designed, and its performance was comprehensively investigated with a PV system. The findings for a sunny day due to the use of a single axis tracking system with a solar panel as compared with those of a fixed panel, that the enhancement in the overall power generation and electrical efficiency are about 28 % and 29 %, respectively.

The higher efficiency of tracking photovoltaic systems is an indisputable fact and computational methods of the respective energy gains are well known. However the investments in the tracking systems are higher in comparison to the fixed ones due to the needs of additional equipment and automation systems. An options of periodical change of the azimuth of PV modules at single axis solar trackers and the correspondent incident solar energy are studied in this paper. An approach for numerical determination of the daily periods of cyclic rotations of the trackers and the subsequent electricity production is developed. It was applied to estimate the energy gains at such cyclic changes of a PV system in ceramic factory in Bulgaria.
