Yes, there are solar panels that track with the sun. These solar panels are called tracking solar systems, and they are designed to move and adjust to capture the most sunlight throughout the day. This type of system requires motors to adjust the angle of the panels, and the most common type is Dual-Axis tracking.
By following the sun as it moves across the sky, tracking solar systems are able to capture about 25% more energy than traditional, fixed-tilt solar systems. The higher efficiency is particularly beneficial for owners who want the most out of their system or need to maximize their solar harvest due to space restrictions.
In addition to capturing more energy, tracking solar systems also benefit from cooler panel temperatures than their fixed counterparts. Cooler panel temps translate to higher efficiency and better performance over the system’s lifespan.
Can you get solar panels that follow the sun?
Yes, you can get solar panels that follow the sun and maximize their efficiency. These types of solar panels are known as “tracking solar panels,” and they use specialized tracking systems to track and follow the sun throughout the day, usually in both the horizontal and vertical direction.
Tracking solar panels are beneficial compared to traditional stationary solar panels, as they are able to capture up to 25 percent more energy than stationary panels on an annual basis, depending on the climate and location.
In order to track the sun, these solar panels are outfitted with sophisticated motorized mounts which enable them to adjust the angle of the panel in both the horizontal and vertical directions throughout the day.
Some tracking devices can measure the position of the sun accurately, while others may need to be manually adjusted if the system is moved or if the climate changes.
Although they are more expensive compared to stationary solar panels, tracking solar panels are worth the investment due to their greater efficiency at capturing energy throughout the day.
Are sun tracking solar panels worth it?
Sun tracking solar panels are worth it because they can significantly increase the energy production from photovoltaic (PV) panels. Sun tracking systems track the sun’s position in the sky throughout the day and adjust the orientation of the solar panels accordingly to optimize its angle relative to the sun.
This adjustment allows for greater exposure to solar rays, meaning that sun tracking panels can capture more of the available energy and increase PV panel efficiency by an average of 10-30% above that of traditional fixed systems.
Additionally, sun tracking systems may also use a light sensor to optimize performance by automatically adjusting the orientation of the panel rather than manually adjusting it. This can be very beneficial in places with frequent or unpredictable weather changes.
Sun tracking systems also require less space than traditional PV systems due to their higher efficiency, allowing PV panels to be installed in a more targeted, space-efficient way. In conclusion, sun tracking solar panels are worth it due to the potential boost in efficiency, ability to adjust to changing weather, and greater space efficiency.
What is the most efficient solar tracker?
The most efficient solar tracker is the dual-axis tracker, which uses two axis of rotation to act as a single unit. The dual-axis system allows it to rotate in both the horizontal and vertical planes to always stay pointed directly towards the sun.
This ensures maximum exposure to the sun’s rays throughout the day, maximizing the efficiency of the solar cell module. Dual-axis trackers can improve solar energy generation efficiency by up to 45% over a fixed installation.
Other solar trackers are single- and dual-axis swing arm that are manually adjusted as the sun moves. These are less efficient and must be adjusted more frequently than dual-axis trackers, so they are not recommended for maximizing efficiency.
Are solar trackers worth it?
It depends on your specific needs and situation. Solar trackers are a valuable asset for those who want to maximize their solar energy production, as they are designed to keep the panels in optimal alignment with the sun throughout the day.
This can result in up to 45% more solar energy production when compared to traditional, fixed-mount systems. Additionally, because they track the sun they can produce more energy in the morning and late afternoon, when traditional systems are typically producing much less.
Not everyone will benefit from having a solar tracking system, however. For those in regions with heavily obstructed sun—such as trees and buildings—the extra gain from using a solar tracker will be minimal.
Additionally, they can be more expensive to install than traditional systems and require more maintenance. Homeowners should also be aware that solar trackers are generally considered to be more of an add-on feature than a standard installation.
Ultimately, the decision whether or not to use a solar tracker should be based on the specifics of your project. A certified solar installer will be able to help you determine if it is worth it for you.
What is a disadvantage of using a tracking solar panel?
A disadvantage of using a tracking solar panel is that they usually require more maintenance and are more expensive than static solar panels. They tend to be bigger and heavier, so they require more space, which can be hard to find in an urban environment.
Additionally, they must be manually adjusted periodically due to changes in the sun’s angle, which can also be a hassle to do. Finally, tracking solar panels require more energy to move, which can detract from the energy production efficiency and collectively contribute to higher installation and operating costs.
How much difference does a solar tracker make?
A solar tracker can make quite a difference in the amount of energy produced through solar energy. A solar tracker is a device that follows the path of the sun and adjusts the solar panels throughout the day to maximize the energy output.
This can be especially useful in locations with long-term cloud coverage since the trackers can better adapt to the changing weather conditions. Solar trackers can also benefit locations with limited space by allowing the system to have more exposure to the sun while taking up fewer ground surface area.
The output increase from solar trackers is often from 10-30% depending on the location and system. In addition, trackers can also reduce system cost in some areas by allowing smaller, higher output systems to be installed, as opposed to larger less efficient systems.
In conclusion, depending on the conditions, installing a solar tracker can make a substantial difference to the output from a solar system. The potential increase in output, cost savings, and practicality may make the cost of the tracker worth it for residential or commercial systems.
