DIFFUSE BOOSTER
DIFFUSE BOOSTER
Installation Options for Cell Placement
The document outlines two primary methods for cell installation related to solar tracking systems:
- Default Installation: Cells are installed on the slewing drive gap.
- Alternative Installation: Cells are installed on the torque tube end when the gap is unsuitable or nonexistent.
Diffuse Booster System Overview
The Diffuse Booster is designed to optimize solar energy capture under diffuse irradiance conditions, particularly during cloudy weather. Key objectives include:
- Accurate identification of stable diffuse light conditions to avoid false detection of broken clouds.
- Maximizing diffuse irradiance capture during cloudy periods to enhance energy yield when direct sunlight is limited.
- Preventing unnecessary tracker movements that could cause production losses.
- Reducing mechanical actuation to minimize wear and operational stress on the system.
- Preserving battery autonomy during extended periods of low irradiance.
By maintaining stable tracker positioning under diffuse-dominated conditions, the system improves energy capture efficiency on cloudy days while ensuring smooth and reliable plant operation.

Catalog excerpts
On very cloudy weather, direct irradiance from the sun could be so minimal that normal monitoring methods are no longer the best way to optimize production. The Algorithm detect those periods displaying a greater irradiance on the horizontal plane (from diffuse irradiance) than on the tracking plane (from direct irradiance) and move trackers to 0°(Diffuse Booster mode). Sensors will be used to read the irradiance in both the tracking and horizontal planes. Diffuse Mode is automatically triggered when the horizontal irradiance exceeds the tracker-plane irradiance for a configurable period. This intelligent logic avoids unnecessary movements, extends battery life, and maximizes energy capture under diffuse conditions. Calibrated cells will be used as irradiance sensors due to their similar spectral response to modules. A centralized set of irradiance sensors will be installed across the plant to enable a coordinated, plant-wide activation of Diffuse Mode. This approach avoids false triggers caused by short-duration cloud transients and ensures stable operation under variable atmospheric conditions. Trackers with calibrated cells installed will always perform normal operation, even if Diffuse Booster mode conditions are met. If they go to 0°, the radiation measurements on the tracking plane will be lost. Diffuse Booster Contents subject to change without prior notice © Sdtec Eneigias Removables * D6.2026/04/22.verQ2
