What is a Solar Tracker?
A solar tracker is a device that automatically orients solar panels to follow the sun's path as it moves across the sky. This allows the panels to capture the maximum amount of sunlight throughout the day, significantly increasing their energy output. There are two main types of solar trackers: single-axis and dual-axis.
A single-axis tracker moves the solar panels on one axis, typically from east to west, allowing them to track the sun's movement throughout the day. While single-axis trackers are more common and less expensive, they are not as efficient as dual-axis trackers.
A dual-axis tracker, on the other hand, moves the solar panels on two axes: azimuth (east to west) and elevation (up and down). This allows the panels to track the sun both horizontally and vertically, maximizing their exposure to sunlight and increasing energy production even further.
Benefits of a Dual Axis Solar Tracker
There are several benefits to using a dual-axis solar tracker for your solar panel system:
- Increased Energy Production: By tracking the sun's movement in two directions, dual-axis trackers can capture up to 45% more sunlight than fixed panels, leading to a significant increase in energy production.
- Improved Efficiency: Dual-axis trackers ensure that solar panels are always operating at their maximum efficiency, regardless of the time of day or year. This can result in higher energy yields and lower energy costs.
- Better Return on Investment: While dual-axis trackers may have a higher upfront cost than fixed panels or single-axis trackers, the increased energy production can lead to a quicker payback period and a higher return on investment in the long run.
DIY Installation of a Dual Axis Solar Tracker
One of the main advantages of a dual-axis solar tracker is that it can be easily installed by DIY enthusiasts without the need for heavy equipment. Many manufacturers offer DIY solar tracker kits that come with all the necessary components and detailed instructions for installation.
To install a dual-axis solar tracker, you will need to follow these steps:
- Site Evaluation: Before installing the tracker, you should conduct a site evaluation to determine the best location for maximum sunlight exposure. Factors to consider include shading, terrain, and the angle of the sun throughout the day.
- Foundation Installation: Once you have chosen the optimal location, you will need to install a foundation for the tracker. This may involve digging holes, setting concrete footings, and securing the tracker in place.
- Mounting the Panels: After the foundation is in place, you can mount the solar panels on the tracker using the provided mounting hardware. Make sure to follow the manufacturer's instructions carefully to ensure proper alignment and operation.
- Wiring and Calibration: Finally, you will need to wire the tracker to your solar panel system and calibrate it to track the sun's movement accurately. This may involve adjusting the angle and orientation of the panels to optimize sunlight capture.
In conclusion, a dual-axis solar tracker is an excellent investment for DIY enthusiasts looking to maximize the efficiency of their solar panel system. With increased energy production, improved efficiency, and easy DIY installation, a dual-axis tracker can help you save money on energy costs and reduce your carbon footprint.
