Installing bifacial solar panels presents several challenges compared to traditional monofacial panels. Here are some of the key installation challenges:
Key Installation Challenges
- Higher Initial Cost: Bifacial panels are generally more expensive than monofacial panels due to higher module costs and possibly requiring specialized racking systems.
- Complex Installation: The installation process for bifacial panels is more complex. Factors such as tilt angle, height, and direction must be precisely optimized to capture light from both sides, which can increase labor costs and setup times.
- Shading Impacts: Shading can significantly affect bifacial panels by impacting both front and rear sides. Sources of shading include nearby structures, trees, and even the mounting system itself. Regular assessments are necessary to ensure both sides remain unshaded throughout the day.
- Dependence on Reflective Surfaces: Bifacial panels rely on reflective surfaces (like snow or light-colored ground cover) to maximize the energy generated from the rear side. In areas lacking such reflective surfaces, the performance benefits may be reduced.
- Potential for Soiling: Unlike monofacial panels, bifacial panels can accumulate dirt on both sides, which requires more frequent cleaning to maintain efficiency.
- Limited Data and Standards: Since bifacial technology is relatively new, there are fewer established standards and less long-term performance data, which can increase uncertainty regarding reliability and bankability.
- Electrical System Requirements: Bifacial panels may require upgraded electrical components (e.g., wires, fuses) to handle the increased power output from both sides.
Resolving these challenges requires careful planning, professional expertise, and an understanding of the specific environmental conditions at the installation site.
