There are several factors to consider when choosing a solar tracker for your solar system. A solar tracker is a mechanical device that orients solar panels to track the sun's movement throughout the day, thereby maximizing its energy production. The following are the main considerations when choosing a solar tracker:

1. Tracking technology: Solar trackers can use different tracking technologies, such as single-axis or dual-axis tracking. Single-axis trackers track the sun's movement from east to west, while dual-axis trackers also adjust based on the sun's altitude. Dual-axis trackers generally have higher energy production potential but can be more expensive. Evaluate which tracking technology is right for your energy goals and budget.

2. Energy production gain: Consider the potential energy production gain compared to a fixed tilt system. Solar trackers can increase energy output by 20 to 40 percent or more, depending on location, site conditions and tracking accuracy. Evaluate the expected benefits of energy production and assess the economic viability of the tracker based on your energy needs and cost constraints.

3. Site Conditions: Evaluate the characteristics of the installation site, including available space, shading, and topography. Solar trackers require unobstructed space to effectively track the sun. If the location is significantly shaded or difficult to access, a solar tracker may not be the most suitable option.

4. Installation and maintenance: Consider installation complexity and ongoing maintenance requirements. Solar trackers involve more mechanical and moving parts than fixed tilt systems, increasing installation complexity and potential maintenance needs. Evaluate the expertise required for installation, the availability and cost of maintenance services, and the impact on system uptime.

5. Cost-benefit analysis: Evaluate the cost of a solar tracking system based on expected energy production gains. Solar trackers are generally more expensive than fixed tilt systems due to additional mechanical components and complexity. Conduct a cost-benefit analysis to determine whether the increased energy production is worth the increased upfront investment and ongoing maintenance costs.

6. Reliability and durability: Consider the reliability and durability of the solar tracking system. Look for a reputable manufacturer with a track record of producing reliable trackers. Consider factors such as material quality, robustness of tracking mechanisms, protection from environmental conditions and warranty terms. Durability is critical to ensuring the long-term performance and longevity of your tracker.

7. Local climate and sunlight conditions: Evaluate local climate and sunlight conditions to determine if a solar tracker would be beneficial. Solar trackers are most effective in areas with large variations in sunlight and seasons. Evaluate the amount of sunlight available throughout the year and the potential for increased energy production provided by solar trackers.

8. Integrate with other system components: Consider how the solar tracker integrates with other components of the solar system, such as inverters, wiring, and monitoring equipment. Ensure compatibility and proper coordination between trackers and other parts of the system to optimize overall performance.

Consulting with a solar professional, installer or manufacturer can provide valuable insight and help you choose the best solar tracker for your specific needs. They can evaluate your site conditions, assess energy production potential, and provide a cost analysis to guide your decision-making process.

In general, horizontal single-axis solar trackers achieve a better balance between radiation reception and cost, so they are the most widely used. For more details, visit Solar Tracker:
