How are horizontal single-axis solar trackers distributed in photovoltaic plants?

This study presents a methodology for estimating the optimal distribution of horizontal single-axis solar trackers in photovoltaic plants. Specifically, the methodology starts with the design of the inter-row spacing to avoid shading between modules, and the determination of the operating periods for each time of the day.

Which axis tracking system is used in large-scale P V plants?

In practice, the horizontal single-axis tracking system is the most commonly used . Because to the high utilisation of the horizontal single-axis tracking system in large-scale P V plants, the optimisation of its performance is a task of great importance.

Does single-axis solar tracking reduce shadows between P V modules?

In this sense, this paper presents a calculation process to determine the minimum distance between rows of modules of a P V plant with single-axis solar tracking that minimises the effect of shadows between P V modules. These energy losses are more difficult to avoid in the early hours of the day.

How does a single axis tracker work?

In the case of the horizontal single-axis tracking, the minimisation is achieved by matching tracker rotation to the projection of the Sun’s position onto the tracking plane of rotation. It is a solar tracker that at noon passes over its horizontal surface, but with continuous movement during the day to follow the solar altitude α S. 2.3.

Which Axis Tracker configuration produces more energy?

Because the single-axis tracker configuration with horizontal North–South axis and East–West tracking produces more energy than the single-axis tracker configuration with horizontal East–West axis and North–South tracking, the former will be the subject of this study.

How does a PV tracking system work?

The tracking system is driven by a single engine. The P V modules rotate from East to West on a horizontal axis, following the Sun’s daily movement. This configuration has a limited range of motion angle (β max). This range depends on the manufacturer. Typical values are β max = ± 60 (°) .
