TL;DR: The presented IoT network aims for enhancing the capabilities of the solar tree beyond just a power generation device to an application such as security, surveillance, pollution monitoring and many more.
Abstract: The presented work describes an interconnected multi-server IoT network for monitoring and control of smart solar tree. The IoT enabled solar tree is introduced as a smart street light with air quality monitoring capability and has been implemented in the Central Electronics Engineering Research Institute, Pilani. The presented network is a three-layer architecture with a sensor node at the lowermost layer for collecting the sensor data. The solar tree server above it performs the sampling of the data by triggering the software for sensor node. Upon successful data collection, the tree server communicates the same to the central server which is responsible for aggregation, visualization, storage, analysis and control of all the connected solar trees. The paper also discusses the implementation aspect of the network and presents the collected data from the solar tree. The presented IoT network aims for enhancing the capabilities of the solar tree beyond just a power generation device to an application such as security, surveillance, pollution monitoring and many more. At present, the work discussed is towards self-sustained street light with ambient monitoring capability.

TL;DR: In this article , the photovoltaic solar tree is used to increase the efficiency of PV systems by reducing the occupied area and optimizing the orientation angles of the panels, which can be used for other purposes such as crop production and parking.
Abstract: The generation of photovoltaic solar energy worldwide has increased significantly in recent years. This is mainly due to the growing demand of society for electricity, the need to reduce environmental impacts, and costs of such technology. The installation of a photovoltaic system with horizontally fixed panels requires a significant unshaded area, which has become increasingly scarce, especially in urban centers. The photovoltaic solar tree is a strategy used to increase the efficiency of photovoltaic systems by reducing the occupied area and optimizing the orientation angles of the panels. The originality of this work was that, through a literature review in different researches, seven relevant parameters related to solar photovoltaic trees were analyzed: (i) modeling and simulation, (ii) tree topology, (iii) orientation of the panels, (iv) constructive characteristics, (v) solar tracking, (vi) occupied area and (vii) site multiple uses. It was found that the photovoltaic solar tree is an interesting alternative to generate renewable energy for places without large enough areas, which can be used for other purposes, such as crop production and parking. Finally, it was concluded that, to date, there are no studies available in the literature on the optimization of photovoltaic generation per area for different topologies of known solar trees.
TL;DR: In this article , different renewable energy sources (PV, wind generators) have been discussed to be installed around the RTU campus and the profiles of electric power consumption are analyzed for one faculty and sport centre.
Abstract: Race to Zero challenge is a world-wide activity for the universities and colleges to foster the climate goals. This paper analyses the potential of Riga Technical University (RTU) for this action. Different renewable energy sources (PV, wind generators) have been discussed to be installed around the RTU campus. The profiles of electric power consumption are analysed for one faculty and sport centre. The consumption profiles show the amount of power demanded during the working hours, weekends and at night. Energy yield assessment on the roofs is made for two buildings where the configuration of PV panel placement and orientation are analysed that in turn is reflected in the energy generation profile. SCADA system is considered as a monitoring and control tool to visualize power generation and control of the power flow within the system elements.

TL;DR: A dependable control system based on the Internet of Things (IoT) to control and manage the energy flow of renewable energy collected by solar panels within a microgrid and maintain system resilience and reliability in real time despite failures of one or more redundant controllers.
Abstract: Solar energy generation requires efficient monitoring and management in moving towards technologies for net-zero energy buildings. This paper presents a dependable control system based on the Internet of Things (IoT) to control and manage the energy flow of renewable energy collected by solar panels within a microgrid. Data for optimal control include not only measurements from local sensors but also meteorological information retrieved in real-time from online sources. For system fault tolerance across the whole distributed control system featuring multiple controllers, dependable controllers are developed to control and optimise the tracking performance of photovoltaic arrays to maximally capture solar radiation and maintain system resilience and reliability in real time despite failures of one or more redundant controllers due to a problem with communication, hardware or cybersecurity. Experimental results have been obtained to evaluate the validity of the proposed approach.

TL;DR: This work presents a smart system for managing public lighting networks based on wireless communication and the DALI protocol, which reduces the need to install new wiring and visual impacts and damage to the facades of historical buildings in city centers are avoided.
Abstract: Public lighting represents a large part of the energy consumption of towns and cities. Efficient management of public lighting can entail significant energy savings. This work presents a smart system for managing public lighting networks based on wireless communication and the DALI protocol. Wireless communication entails significant economic savings, as there is no need to install new wiring and visual impacts and damage to the facades of historical buildings in city centers are avoided. The DALI protocol uses bidirectional communication with the ballast, which allows its status to be controlled and monitored at all times. The novelty of this work is that it tackles all aspects related to the management of public lighting: a standard protocol, DALI, was selected to control the ballast, a wireless node based on the IEEE 802.15.4 standard with a DALI interface was designed, a network layer that considers the topology of the lighting network has been developed, and lastly, some user-friendly applications for the control and maintenance of the system by the technical crews of the different towns and cities have been developed.

Abstract: The following paper proposes a solar metering system which can be accessed from anywhere for monitoring and analysis of solar setups. It monitors the solar output in real time with ease and therefore any interruption in the system can be immediately monitored. This IOT (Internet of Things) based system is best suited for remote areas where solar systems are setup due to ample availability of solar energy but regular access to the areas is difficult and is not cost efficient. With the demands of renewable and solar energy escalating, this system's demand and usefulness will blatantly increase. The system comprises of Raspberry PI (a Microcontroller based Computer), MCP3008 (Analog to Digital Convertor), DC Voltage Transducer and current shunt. The system has been developed using Virtual Instrument Programming Language LabVIEW.
