Quick Answer
Different mounting heights can impact bifacial solar output. Bifacial solar panels generate electricity from both the front and rear sides, and the rear side output is affected by the surrounding environment and the distance of the panel from the ground.
Bifacial Solar Panel Orientation and Distance to Ground
Bifacial solar panels require some distance between the panel and the ground to maximize rear-side light absorption and energy production. Research suggests that for optimal energy production, panels should be mounted at a height of 1-2 meters (3-6 feet) above the ground. This distance allows for efficient rear-side light absorption and minimizes shading from nearby obstacles.
Impact of Mounting Height on Bifacial Solar Output
Studies have shown that bifacial solar panels mounted at a height of 1.5 meters (4.9 feet) above the ground can increase energy production by 10-20% compared to panels mounted at 0.5 meters (1.6 feet). This increase in energy production is due to the improved rear-side light absorption and reduced shading. The optimal mounting height may vary depending on the specific installation environment and panel type.
Considerations for Maximizing Bifacial Solar Output
To maximize bifacial solar output, it’s essential to consider the installation environment, panel type, and mounting height. Installers should ensure that panels are mounted at a height that minimizes shading and maximizes rear-side light absorption. Additionally, using a bifacial-specific mounting system can help optimize energy production and ensure a reliable installation.
