Quick Answer
To achieve the most effective setup for bifacial panels, ensure optimal spacing between panels, typically 20-30 cm, to allow for maximum light absorption on both sides, and orient panels at a 5-10 degree angle to reduce shading and increase energy output.
Bifacial Panel Orientation and Spacing
When installing bifacial panels, consider the optimal orientation to maximize energy production. Panels should face south to receive direct sunlight, but also consider a slight angle to reduce shading and increase light absorption on both sides. The ideal angle is between 5-10 degrees, as it allows for optimal light absorption while minimizing losses.
Tracking and Shading Mitigation
To maximize energy output from bifacial panels, consider using tracking systems or adjustable mounts that allow for slight adjustments in panel orientation to compensate for seasonal changes or obstructions. This can help mitigate shading effects from nearby structures or trees, ensuring consistent energy production throughout the year. For fixed systems, maintain a minimum spacing of 20-30 cm between panels to prevent shading and allow for maximum light absorption.
Installation and Maintenance Considerations
During installation, ensure that ground-mounted systems are designed to accommodate both the weight and wind load of bifacial panels. Regular maintenance is crucial to prevent dirt and debris accumulation on panels, which can decrease energy output. Consider installing panels at a slightly higher elevation to facilitate easier cleaning and maintenance.
