Can bifacial solar panels be used in agricultural settings?

Bifacial solar panels can indeed be used in agricultural settings, offering several benefits over traditional solar panels. These panels generate electricity from both the front and rear surfaces, making them more efficient in certain conditions, especially when sunlight reflects off surfaces like grass or soil.

How Bifacial Solar Panels Work in Agriculture

Bifacial solar panels are particularly suited for agricultural settings because they can be mounted in various configurations to maximize energy production. For example, they can be installed vertically, allowing for dual-sided power generation. This setup can be used in practical applications like solar fences, which not only produce energy but also act as a barrier.

Real-World Applications

• Agri-PV Systems: In the UK, companies like Next2Sun are promoting agri-photovoltaic (agri-PV) systems. These systems allow farmers to maintain agricultural activities while generating renewable energy. This approach is becoming more popular as farmers seek to diversify their income streams and reduce reliance on traditional farming alone.

• Solar Fences: A notable example of bifacial solar panel use in agriculture can be seen in installations like solar fences. These can be particularly beneficial on dairy farms, where energy demand peaks during morning and evening milking sessions, aligning with the energy generation patterns of bifacial panels facing east and west.

Pros and Cons of Bifacial Solar Panels in Agriculture

Pros

• Efficiency: Bifacial panels are typically 10 to 30% more efficient than conventional panels, especially in diffuse sunlight conditions found in the UK.
• Dual-Purpose Use: They enable dual use of land for both energy generation and farming, which is crucial in maintaining agricultural productivity.
• Longer Lifespan: Bifacial panels often have longer lifespans, typically over 30 years.

Cons

• Higher Cost: Despite their efficiency advantages, bifacial panels are more expensive upfront compared to traditional solar panels.
• Installation Complexity: Depending on the setup, bifacial panels may require more complex installation to maximize their efficiency.

Practical Advice and Common Mistakes

• Assess Land Suitability: Before installation, assess whether your land is suitable for solar panels, considering factors like sunlight exposure, soil quality, and local agricultural needs.
• Choose the Right Setup: Ensure that the solar panel setup aligns with your agricultural practices and energy needs. For example, vertical installations might be more appropriate for fields where livestock graze.
• Consult Experts: Work with solar panel specialists who have experience with agricultural installations to avoid common mistakes like poor placement or insufficient maintenance.

With clear understanding and thoughtful planning, bifacial solar panels can be a valuable addition to agricultural settings in the UK, providing both economic benefits and supporting sustainable energy goals.
