Disadvantages: Solar trackers are slightly more expensive than their stationary counterparts, due to the more complex technology and moving parts necessary for their operation. This is usually around a $0.08 – $0.10/W increase depending on the size and location of the project.
Solar photovoltaic technology is an essential resource for renewable energy. However, current solar photovoltaic systems have significant disadvantages, including high costs compared to other resources, low efficiency, and intermittency. Capturing maximum energy from the sun using these systems can be challenging.
While solar tracking can increase the efficiency of a PV system, it’s not always viable. For instance, if the locale of the PV project is on undulating terrain, specialists need to evaluate the geotechnical conditions and decide if the project would benefit from the trackers or if the fixed-tilt is a better fit.
According to research, the efficiency of such solar trackers ranges from 27.85 % to 43.6 % compared to a fixed photovoltaic system, and the solar tracking accuracy reaches from 0.11° to 1.5°. Controllers and electrical drives include Arduino, Atmega, dSpace, as well as DC motors, stepper motors and servo motors, respectively.
The efficiency of the developed solar trackers based on photoresistors demonstrates a significant increase in performance compared to stationary PV systems: from 11 % to 57.4 % for single-axis solar trackers and within 4–52.78 % for dual-axis solar trackers. In this case, solar tracking errors range from 0.05° to 1.67°.
The advantage of solar trackers with a parallel mechanism is the high accuracy of solar tracking due to their parallel mechanism, and the ability to be installed in different climatic conditions and geographic latitudes.
