Quick Answer
Bifacial solar panels offer improved efficiency and increased energy output compared to monofacial models by capturing solar radiation from both sides of the panel, resulting in higher yields and reduced installation costs. This technology is particularly effective in areas with high levels of diffuse radiation or reflected light. Overall, bifacial panels provide a more efficient and cost-effective solution.
Understanding Bifacial Technology
Bifacial solar panels are designed to capture solar radiation from both the front and back sides of the panel. This technology is made possible by the use of a transparent substrate on the rear side, which allows sunlight to pass through and be absorbed by the cells. The rear-side reflection can increase the panel’s efficiency by 10-25% depending on the installation environment. This means that a 300-watt monofacial panel could be equivalent to a 330-375-watt bifacial panel.
Installation Considerations
While bifacial panels offer several benefits, proper installation is crucial to maximize their performance. A minimum distance of 1 meter between the panels and the ground is recommended to allow for adequate rear-side light reflection. Additionally, the panels should be installed at an angle that allows for optimal rear-side exposure to sunlight. A south-facing roof with a 15-30 degree angle is ideal for bifacial installations.
