Do solar tracking systems improve the efficiency of photovoltaic modules?

Solar tracking systems (TS) improve the efficiency of photovoltaic modules by dynamically adjusting their orientation to follow the path of the sun. The target of this paper is, therefore, to give an extensive review of the technical and economic aspects of the solar TS, covering the design aspects, difficulties, and prospects.

What is solar photovoltaic bracket?

Solar photovoltaic bracket is a special bracket designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. The general materials are aluminum alloy, carbon steel and stainless steel. The related products of the solar support system are made of carbon steel and stainless steel.

How to design a photovoltaic system?

This consists of the following steps: (i) Inter-row spacing design; (ii) Determination of operating periods of the P V system; (iii) Optimal number of solar trackers; and (iv) Determination of the effective annual incident energy on photovoltaic modules. A flowchart outlining the proposed methodology is shown in Fig. 2.

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.

What types of solar photovoltaic brackets are used in China?

At present, the solar photovoltaic brackets commonly used in China are divided into three types: concrete brackets, steel brackets and aluminum alloy brackets. Concrete supports are mainly used in large-scale photovoltaic power stations. Because of their self-weight, they can only be placed in the field and in areas with good foundations.

How do solar tracking systems compare?

Consequently, the main metrics available in the literature for the comparison of solar tracking systems relate to aspects such as annual energy gain, which can be evaluated in terms of the power output ratio, local latitude, and solar radiation , .
