... example, in the physical lab to alter the irradiance hitting the PV sample panel is carried out by moving the panel towards or away from the light source. In addition to an experimental rig that would function as the apparatus in Figure 1, a user control interface would be required as shown in Figure 2. Therefore, the design of the experiment required automation controls that could be operated at a distance without need for human intervention. ...

The proliferation of photovoltaic systems in the last decade demands skilled technologists familiar with the theoretical and practical aspects of solar system technology. Hands-on experiments play a key role in the development of students' creativity and instinctive understanding of concepts. In this paper, we explain the process of developing a lab manual to introduce diploma-level undergraduate students to power-electronics aspects of a solar system. Experimental test setup and different equipment used for data acquisition purposes are detailed first. We then briefly explain theoretical concepts such as solar panel modeling, maximum power point tracking, total harmonic distortion, pulse width modulation, and filter design. MATLAB/SIMULINK is used as the simulation platform for virtual experiments due to its user friendliness and capabilities. Hands-on and simulation-based experiments and the results are explained and analyzed. This steppingstone project serves to solidify students' learning of practical aspects of solar energy harvesting through experimental learning.

Os resultados positivos demonstrados por diversas pesquisas sobre o uso de novas tecnologias da informação na educação evidenciam novas formas de atrair e engajar estudantes no processo educativo. Uma dessas tecnologias, chamada de Jogos Sérios, propõe a utilização de jogos digitais com finalidades para além do entretenimento do jogador, como educação, marketing e política. Esta pesquisa descreve o desenvolvimento de um jogo sério voltado ao processo de ensino-aprendizagem de normas, procedimentos e termos técnicos sobre sistemas fotovoltaicos. O jogo Phototype foi desenvolvido sob o apoio de metodologias voltadas a jogos educacionais, como o Heuristic Framework e o Learning Mechanics – Game Mechanics; e avaliado por intermédio de um questionário e instrumentos técnicos que observaram a percepção dos estudantes de um curso superior em relação às mecânicas de jogo e aprendizado do jogo digital. Os resultados da pesquisa identificaram uma experiência positiva por parte dos estudantes na utilização do jogo Phototype, sugerindo sua importância como ferramenta educacional e de apoio ao ensino-aprendizagem, complementando o resultado de pesquisas anteriores.

There are also various experiments in the photovoltaic domain [10]. Some more specialized laboratories offer chemical experiments [11], experiments on radio communications [12], or include manufacturing methods in a remote laboratory [13]. ...
This work focuses on the requirements analysis of a modular framework to simplify developing and integrating new or existing remote experiments and laboratories. Besides this technical view, this paper also gives an organizational view on developing such a framework and managing the corresponding modules, which can also be developed by a third party. On a technical side, we provide the requirements to ultimately define the interface between different modules, enabling easy integration on different abstraction levels.

An existing lab experience can be made remotely accessible in a relatively easy way. The problem is with the design of a tool which allows any kind of experience to be made remotely accessible. The complexity of this tool is out of discussion. Several universities have been working on it for years. In fact, the Huelva University presented the work “A Complete Solution for Developing Remote Labs” in the 10th IFAC Symposium on Advances in Control Education (2013). Such complete solution was the result of those universities working together. Since then, the joint-work has continued and improvements have also been achieved. Hereafter, a fully open integrated system is presented whose scope is greater than that of 2013. It offers a way to easily implement cloud services for managing the configuration and access to all type of sensors, actuators and controllers (the devices base of the any remote lab). The access proposed is secure, controlled, organized and collaborative.

Electricity access is a key driver for developing a modern society. The use of locally generated renewable energy can overcome limitations of expensive grid infrastructure. However, there are still barriers to access particularly for the rural poor in the global south. When individuals or communities invest in electricity provision it is important to know how well the system is performing. Commercial monitoring systems have been developed for large scale renewable energy systems. The cost of these can outweigh the cost of a small decentralised renewable energy system. This paper describes the development of a low cost data logger that is going to be used to monitor the system performance of small photovoltaic nano-grids in Kenya and Bangladesh. The device performs within the expected range for the current, voltage, temperature and irradiance sensors. Data from the data logger device is sent via GPRS to a website where it can be accessed as real time graphical displays and data files.
The project Open Digital Lab for You (DigiLab4U) focuses on the creation of a net-worked laboratory-based learning environment where students, teachers and researchers can access industry related laboratory equipment focusing on the Internet of Things (IoT) and Industry 4.0 (I4.0). This paper describes the alignment of the didactical requirements with the technical design and architecture to build up a sustainable remote laboratory system for study, teaching and research. The focus is on the development of a dashboard and corresponding technical integration for remote access of an RFID measuring chamber. The remote chamber will be used in the Information Logistics study program at the Hochschule für Technik Stuttgart (HFT Stuttgart) as part of laboratory exercises and will be available to other users across universities in the future. Subsequently the initial project idea is briefly described (1), technical design according to the didactical demands are outlined (2, 3) and first evaluation results will be presented (4).
Nowadays remote access to systems in the instrumentation and measurement fields is both a reality and a challenge. There is a growing interest in replacing manual actions performed on site by remote actions carried out from anywhere around the world. To do that, besides the availability of suitable communication networks, it is necessary for the elements involved in the network to recognize each other, this latter task perhaps being the most complex one of the two. Integrating different hardware/software from different manufacturers into a single system with controlled remote access is not a trivial task. This paper presents a fully integrated open solution for the operation of pilot plants (scaled down, laboratory level industrial plants operated in university and other environments) using open access hardware/software on public networks. The proposed solution is independent of the nature of the pilot plant and its elements and can therefore be considered standard. In order to illustrate the capabilities of the proposed solution, two different types of pilot plant are presented.
