What is Diffuse Optimization?

Solar diffuse optimization is a strategy to increase solar energy production on cloudy or overcast days by adjusting solar panels to capture scattered light. Unlike algorithms that prioritize direct solar radiation, this method constantly adjusts the tracker’s position to absorb light reflected from clouds, the ground, or surrounding objects. It is a critical factor for boosting energy production.

This strategy is essential for increasing the total energy output of a solar installation, especially when using bifacial modules or operating in climates with frequent cloud coverage.

How does diffuse optimization work?

Diffuse optimization works by dynamic panel tracking based on real-time atmospheric and ground conditions. Instead of simply following the sun’s direct path, the tracker’s software analyzes light data from multiple sources. It then calculates the optimal tilt and azimuth angle to capture the most diffuse light. This is particularly effective with bifacial panels, as the albedo effect (light reflecting off the ground and onto the rear of the panel) can be significantly harnessed.

What are the main challenges to implementing diffuse optimization?

Implementing this strategy effectively demands more than just a basic tracking algorithm. It requires sophisticated control systems with advanced software and on-site weather sensors. The main challenge is accurately collecting and processing data to make precise adjustments. Without real-time, site-specific data on cloud cover and ground reflectivity, a tracker may miscalculate and actually reduce total energy output, creating a need for more intelligent solutions.

What is the impact of diffuse optimization on solar projects in 2025?

In 2025, advanced diffuse optimization is moving from a niche feature to a standard for high-performance solar assets. As bifacial modules become more common, software that can intelligently manage both direct and diffuse light will be key to increasing a project’s profitability. This is essential for developers and EPCs aiming to maximize yield on sites with complex terrain or those located in regions with frequent cloudy weather.

How does Solargik’s technology apply diffuse optimization?

Solargik’s SOMA Pro SCADA system leverages diffuse optimization as part of its AI-powered control platform. The software analyzes real-time site data to precisely position trackers, maximizing energy capture from all available light sources, including diffuse radiation. This is especially impactful for the VersaTrack and Agri-PV Track systems on challenging terrains, where the ground’s irregular surface creates unique reflective patterns. This ensures every project, regardless of location, achieves its highest possible energy yield.

Key Takeaways

• Diffuse optimization is crucial for maximizing the performance of modern bifacial solar modules by capturing more indirect light.
• It enables developers to increase a project’s energy yield and internal rate of return, especially on projects in non-ideal locations or climates.
• Advanced control software is needed to effectively implement diffuse optimization strategies and unify data from multiple on-site sensors.
