Technological Drivers of Output
Achieving this level of consistent energy output requires sophisticated hardware configuration. The plant utilizes dual-axis trackers, a technology choice that significantly enhances energy yield compared to fixed-tilt systems. By adjusting the orientation of the photovoltaic panels both horizontally and vertically throughout the day, the trackers maximize the angle of incidence of solar radiation. This is particularly advantageous in the Extremadura climate, where solar irradiance can vary with seasonal shifts and daily cloud cover. The use of dual-axis tracking ensures that the panels capture sunlight more efficiently during the early morning and late afternoon hours, effectively extending the peak production window.

What distinguishes dual-axis trackers from fixed-tilt systems?
Dual-axis tracking systems represent a significant technological divergence from standard fixed-tilt photovoltaic arrays, particularly in regions with high direct normal irradiance like Extremadura. Unlike fixed-tilt systems, where panels are mounted at a static angle optimized for the sun’s average position, dual-axis trackers adjust their orientation continuously along two degrees of freedom: azimuth and elevation. This allows the solar modules to follow the sun’s path across the sky from sunrise to sunset, minimizing the angle of incidence between the sunlight and the panel surface.
Mechanisms of Efficiency Gains
The primary advantage of dual-axis tracking is the maximization of direct beam radiation capture. In a fixed-tilt configuration, the angle of incidence changes throughout the day and season, causing cosine losses—where the effective area of the panel exposed to perpendicular sunlight decreases. Dual-axis trackers mitigate this by keeping the panel surface nearly perpendicular to the sun’s rays for a larger portion of the day. This is particularly effective for the 30 MW Spex solar park, where each panel has an area of 130 m2. By optimizing the exposure of this substantial surface area, the system can generate more energy per kilowatt-peak installed compared to a fixed array of the same size.
Additionally, dual-axis tracking can enhance performance during the spring and autumn equinoxes, when the sun’s path is most variable in elevation. Fixed-tilt systems are often optimized for winter or summer solstices, sacrificing efficiency in the intermediate seasons. Dual-axis systems adapt to these seasonal shifts automatically, reducing the need for complex manual adjustments or hybrid mounting structures. This dynamic adaptation contributes to a more consistent energy output profile, which can be valuable for grid integration and revenue optimization for operators like ecoEnergías.
Trade-offs and Implementation
While dual-axis trackers offer higher energy yields, they introduce greater mechanical complexity and maintenance requirements compared to fixed-tilt systems. The moving parts—motors, gears, and sensors—are subject to wear and weather exposure, potentially increasing operational expenditures. Furthermore, the spacing between rows of panels must be wider to prevent shading, which can affect land-use efficiency. For the Spex project, which occupies a 195-hectare site, the land area was sufficient to accommodate the necessary spacing for dual-axis movement without significant land-cost penalties. The investment in tracking technology was part of the €250 million development cost, reflecting a strategic choice to prioritize energy yield per module over minimal land usage or mechanical simplicity. This technology choice aligns with the goal of supplying power to 16,000 households, maximizing the output from the installed capacity.
