Quick Answer
A tracking system can increase energy production from bifacial solar panels by up to 30%, but it's worth it only if the additional upfront cost can be recouped within the system's lifetime, typically 25 years.
Understanding the Benefits of Bifacial Solar Panels with Tracking Systems
Bifacial solar panels are designed to capture light from both the front and back sides of the panel, increasing energy production. When paired with a tracking system, these panels can adjust to follow the sun’s movement and angle, further boosting energy output. This setup is particularly effective in areas with high sunlight exposure and minimal shading.
Calculating the Cost-Effectiveness of Tracking Systems for Bifacial Panels
To determine if a tracking system is worth it for bifacial solar panels, calculate the additional upfront cost and compare it to the increased energy production. For example, a 10 kW system with bifacial panels and a tracking system might cost $50,000 more than a fixed system. If the system produces 30% more energy, this could translate to an additional $15,000 in annual energy revenue, assuming a 10% return on investment. Over the system’s 25-year lifetime, this could lead to a total revenue increase of $375,000, making the additional upfront cost more than justified.
Practical Considerations and Technical Requirements
Before investing in a tracking system for bifacial solar panels, consider factors like terrain, shading, and local climate. Ensure the tracking system is suitable for the panel’s design and power output. Also, consider the system’s reliability, maintenance requirements, and potential for future upgrades. A well-designed tracking system can significantly enhance the performance of bifacial solar panels, but it’s essential to carefully evaluate the costs and benefits before making a decision.
