“…It is the amount of radiant flux incident on a surface and is expressed in watts per square meter (W•m −2 ). The R s parameter is frequently integrated over time to determine the radiant energy emitted into the surrounding environment (joules per square meter, J•m −2 ) during that period [88,89]. 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]. The greater the angle, the lower the solar intensity, which is why the R s parameter is less intense in the morning and evening than at noon [89,101].…”

“…To the best of the understanding of the authors, there is a potential to integrate the solar tracking system into the agrivoltaic system [4,5,30,53]. According to [77,88,130], a solar tracker system can be classified based on the techniques used to control the movement of the PV panels. The tracker system can be a passive, active [78,89], or chronological tracker system [77].…”

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

Agrivoltaic systems (AVS) offer a symbiotic strategy for co-location sustainable renewable energy and agricultural production. This is particularly important in densely populated developing and developed countries, where renewable energy development is becoming more important; however, profitable farmland must be preserved. As emphasized in the Food-Energy-Water (FEW) nexus, AVS advancements should not only focus on energy management, but also agronomic management (crop and water management). Thus, we critically review the important factors that influence the decision of energy management (solar PV architecture) and agronomic management in AV systems. The outcomes show that solar PV architecture and agronomic management advancements are reliant on (1) solar radiation qualities in term of light intensity and photosynthetically activate radiation (PAR), (2) AVS categories such as energy-centric, agricultural-centric, and agricultural-energy-centric, and (3) shareholder perspective (especially farmers). Next, several adjustments for crop selection and management are needed due to light limitation, microclimate condition beneath the solar structure, and solar structure constraints. More importantly, a systematic irrigation system is required to prevent damage to the solar panel structure. To summarize, AVS advancements should be carefully planned to ensure the goals of reducing reliance on non-renewable sources, mitigating global warming effects, and meeting the FEW initiatives.

The work is devoted to the development of an efficient photovoltaic installation with automated wireless monitoring based on the LabView software. Long-distance communication technology - LoRa was used to wirelessly transmit data on the output characteristic states of the photovoltaic installation, storage battery and built-in sensors. This module operates at 433 MHz and transmits small data packets with low power consumption. This makes the stand-alone system energy efficient compared to similar wireless installations. The graphical software LabView was chosen to monitor the state of the developed system. The paper shows a block diagram of an automated wireless system, an operational algorithm of the external transmitting part of the installation, as well as electrical circuits of the transmitting and receiving control units. As a result of the work, a photovoltaic system with an automated wireless monitoring system and graphical data display was developed. The developed automated complex is more efficient and easy to use in comparison with other systems.

“…In the article of Ponniran [3], by instance, that barrier scheme to adjust the position of the tracker was used with light dependent resistors, or LDRs, a kind of photosensor. In a more recent paper, Kuttybay compared the use of a LDR photosensor with a scheduled scheme by using an encoder sensor to measure the angle shift and the displacement needed to track the azimuth angle of the sun [4]. That study concluded that such an approach was 4.2% more efficient than using a LDR solar tracker in different weather conditions.…”

The single axis solar tracker based on flat panels is used in large solar plants and in distribution-level photovoltaic systems. In order to achieve this, the solar tracking systems generally need to work by tracking the sun’s position with dozens, maybe hundreds of movements along the day with a maximal known tracking error within the specifications. A novel model is proposed along this work based on the control of the angle deviation within a (polar) single axis configuration. This way an optimization of the harnessing of solar energy can be achieved with as few panel displacements as possible in order to decrease the wear in the mechanical parts of the equipment and the energy consumed by it. This tracking approach was implemented with as few as seven positions along the day and got an estimated theoretical value of 99.27% of the total collected energy in a continuous tracking system. Regarding an annual average basis, it would be about 96.5% of a dual axis system according to the proposed model. The novelty of the model is related to a tradeoff between the gain with the simplicity of a single axis n-position tracking and the solar energy loss associated.
