Bifacial Solar Panels: Maximizing Energy Capture

Installation Optimization

The optimal installation of bifacial solar panels requires careful consideration of several key factors to maximize their unique dual-sided energy generation capabilities. Height positioning plays a crucial role, with panels typically installed 1-2 meters above the ground to ensure adequate light reflection reaches the rear surface. The ground surface beneath the panels should ideally be light-colored or reflective, with white gravel or light-colored concrete offering excellent albedo properties.

Panel tilt angle and spacing deserve special attention in bifacial installations. European installations generally benefit from a tilt angle between 20-35 degrees, depending on geographical location, while row spacing should be increased by 15-20% compared to traditional panels to minimize row-to-row shading and optimize rear-side exposure.

For maximum efficiency, installers should consider the surrounding environment, including potential shade sources and reflective surfaces. Regular maintenance of the ground surface and keeping vegetation controlled beneath the panels ensures consistent rear-side performance. Advanced mounting systems with minimal structural shading can increase rear-side energy yield by up to 5-10%, making them a worthwhile investment for long-term performance optimization.
