Technologies of solar tracking systems: A review

Abstract

Solar energy is abundantly in nature and sustainable energy resources around the world. The main challenge with the solar field is less amount of sun energy captured by using photovoltaic (PV) systems. The great performance of the PV systems can be achieved if the panel is kept perpendicular to the direction of the radiations of sun. Hence, solar tracker system is the method to keep the optimum position of the PV panel for always perpendicular to the solar radiation. This paper aims to review on various technologies of solar tracking to determine the best PV panel orientation. The various types of technologies of solar tracking system have been discussed which includes passive solar tracker, active solar tracker and chronological tracker system. The movement degrees of solar tracking system also have been addressed which consisting single-axis solar tracking system and dual-axis solar tracking system. This paper is also overviews the tracking techniques performance, construction, performance, advantages, and disadvantages of existing solar tracking system. The limitations of solar tracking systems are also highlighted for future action improvement. Through this research studies, the most favorable solar tracking system was identified as active solar tracker with the dual axis rotation.

Solar Photovoltaic Architecture and Agronomic Management in Agrivoltaic System: A Review

“…At the same time, solar radiation can also be converted to electricity using solar power systems. Solar systems are classified into two types: photovoltaic (PV) systems that convert sunlight directly to electricity using semiconductor materials [36,[76][77][78][79] and concentrated solar power (CSP) systems that convert sunlight to heat before using the heat to produce electricity [30,41,46,51,80]. Despite the fact that both processes need solar radiation to occur, the photosynthesis process is concerned more with the Photosynthesis Active Radiation (PAR) range [47,52,68,[81][82][83] while electrical energy generation is dependent on solar irradiance or light intensity [8,15,35,84,85].…”

“…In contrast, the intensity with which radiation enters the atmosphere is the solar irradiation, R s [28,77]. It is the amount of radiant flux incident on a surface and is expressed in watts per square meter (W•m −2 ).…”

“…This total solar irradiance is referred to as solar irradiation. The amount and intensity of R s that the earth's surface receives depends on a variety of factors such as cloud cover [81,[90][91][92][93], latitude [6,73,80,94], altitude [77,78,90,95], season [73,93,[96][97][98], weather [19,38,40,99,100], and daytime [34,46,48,76,101]. In addition, the distance that radiation has to travel is dependent on the angle of the sun [88,93].…”

Solar Tracker Elektro-Pneumatik Berbasis Kendali Fuzzy

“…Penggunaan motor servo sebagai aktuator untuk menggerakan posisi sudut generator turbin angin atau panel surya memiliki kekurangan. Pasokan energi listrik untuk menggerakan motor servo berasal dari pembangkit internal yang dihasilkan [8] [9]. Dampak dari penggunaan motor servo adalah berkurangnya daya keluaran listrik untuk ke jaringan beban [11] [13].…”

Algılayıcı Türlerinin Güneş Takip Sisteminde Etkinliğinin Araştırılması

“…Mevcut sistemlerin performans analinizi yapılmış, avantaj ve dezavantajlarına değinilmiştir. Araştırma sonucunda en verimli sistemin çift eksenli rotasyon ile aktif güneş takip sistemleri olarak belirlenmiştir (Amelia et al, 2020). Ammach ve Attia, iki eksenli güneş takip sistemi önermişlerdir.…”
