Can you rotate solar panels to follow the sun?
Yes, solar panels can be mounted on a tracking system that rotates the panels to follow the sun as it moves across the sky. This type of system, called a single-axis or dual-axis tracker, increases the amount of energy the panels can produce by ensuring that the panels are always pointed directly at the sun. The increased energy production can offset the added costs and complexity of the tracking system.
Also tend to be more expensive and complex to install and maintain than fixed-tilt systems. It's also worth noting that while tracking systems can increase energy production, they also add mechanical components that can break or malfunction, which can reduce the overall reliability of the system. Additionally, the added costs associated with these systems may not be recouped over the lifetime of the panels, especially if the system is not installed in an area with high levels of sunlight.
Another thing to consider is that while the tracking systems are very effective in increasing the energy production during the peak sun hours, they may not be as effective during the early morning and late afternoon. This is because the sun is at a lower angle in the sky and the panels might not be able to capture as much sunlight.
Additionally, tracking systems require more space compared to fixed-tilt systems, as the panels need room to rotate. This can be a limitation for some installations where space is limited.
Overall, while tracking systems can be a great way to increase energy production from solar panels, they are not always the best option for every installation. Factors such as location, climate, space constraints and budget should be considered before deciding to install a tracking system. It's worth consulting with a solar professional to determine if a tracking system is the right choice for your specific needs.
