“…The classification of a solar follower is based on the number of axes, control scheme, freedom of movement, and drivers shown in Figure 6. The driver‐based Sun followers are classified as: Passive trackers 8‐13 Semi‐Passive trackers 14‐17 Chronological trackers 18,19 Manual trackers 20 Active trackers 21‐27 …”

Review transcript presents copious solar tracking methods to investigate their output potential and also outline tracker type, construction, cost, and design parameter. The solar follower systems encompassed five classifications based on the tracking methods are active, passive, semi-passive, manual, and chronological tracking are also reviewed with their application and feasibility. These all method-based research paper are compared on the basis of complexity of circuit, cost, tracking based on (radiation or astronomical equation), degree of freedom, control strategy, accuracy, energy intact, power or energy gain, tracing error, and panel efficiency. Basically, one axis and two axis sun following system review revels compare study against stable system which addressed their suitability and capability of maximum energy generation and MPPT technologies.

“…This type of tracking utilizes a concept known as beam steering [28,29]. Several studies have explored the use of mechanical movements using mirrors, prisms, or even beam-steering lens arrays (BSLA) to achieve this goal [30][31][32][33][34][35]. In the case of the BSLA system, an experimental study was conducted where, despite recording a lower than expected performance, the proof-of-concept demonstrated the feasibility of this type of tracking system.…”

Tracking-Integrated CPV Technology: State-of-the-Art and Classification

et al. 2023

Concentrator photovoltaic (CPV) technology offers an alternative to conventional photovoltaic systems, focusing on the concentration of solar radiation through the optics of the system onto smaller and more efficient solar cells. CPV technology captures direct radiation and requires precise module orientation. Traditional CPV systems use robust and heavy solar trackers to achieve the necessary alignment, but these trackers add to the installation and operating costs. To address this challenge, tracking-integrated CPV systems have been developed, eliminating the need for conventional trackers. These systems incorporate tracking mechanisms into the CPV module itself. This review presents a detailed classification of existing designs in the literature and provides an overview of this type of system with different approaches to integrated tracking including tracking concentrator elements, using external trackers, or employing internal trackers (the most researched). These approaches enable the automatic adjustment of the CPV system components to follow the movement of the Sun. The various tracking-integrated systems have different designs and performance characteristics. Significant progress has been made in developing tracking-integrated CPV systems with the aim to make CPV technology more competitive and expand its applications in markets where traditional CPV has been excluded.

“…The test is done by determining the three values of the slope angle with the aim of getting the value of effectiveness on the Fresnel lens and can reduce the influence of blocking and shading on the receiver, so that the amount of solar energy received can be maximized. In this study the effectiveness of Fresnel lenses can still be improved by taking into account the factor of the distance between Micro-heliostat, the number of Microheliostat and the slope of the array [10].…”

This paper presents the use of sunlight trackers to increase the efficiency of solar panels. The sunlight tracking is done by passive and active tracking method with one or two axis. The active trackers use an electrical motor as a driver and can be controlled by a microcontroller or a programable logic controller (PLC) according to the direction of sunlight. The use of this controller in sunlight tracking system performed in real time or periodically. The position of the sun as a controller input can be obtained based on azimuth angle and solar elevation angle or by direct measurement using sensors. From the discussion is obtained an increase of efficiency of 29.37% in avarage using the active tracker.
