Advantages of Using a Sun Tracker for Solar Panel Optimization
Managing the angles of solar panels take time and effort. Manually adjusting the angles of PV panels requires patience, as one must tilt the units based on the movement of the sun.
For optimized tracking, solar panel system owners can use a sun tracker. The device is designed to automate the tilting process, which increases the efficiency of harvesting sunlight throughout the day.
Benefits of Solar Trackers
Solar trackers offer several advantages for individuals. By maximizing sunlight exposure during the day, owners can significantly boost the amount of energy harvested by the unit. Moreover, solar panels with sun trackers provide increased output by up to 30 percent (depending on the type of tracker installed), compared to stationary panels. Such benefits equate to a faster return on investment, as well as faster battery charging times.
It is important to consider that not all locations are suitable for sun tracking. Warm-climate regions and areas that receive minimal snowfall may get more out of their solar tracking device, compared to cold-climate regions.
Types of Sun Trackers for Solar Panels
Single-axis and dual-axis models are the two most common types of sun trackers. Single-axis tracking devices move from east to west and only tilt in one angle. The unit’s efficiency is maximized during spring and summer seasons. High-latitude locations may consider using a vertical-axis sun tracker for optimized performance.
Next, as the name suggests, a dual-axis tracker for PV panels incorporates a wider scope of movement, via two degrees of freedom (primary and secondary axis).
When it comes to driving the trackers, individuals have two options: passive tracking and active tracking. Passive tracking relies on compressed gas fluid and is considered to be less accurate than other tracking alternatives. Active tracking options use motors and gears to adjust the panels, based on a controller.
