The laboratory stand for measurements and analysis of photovoltaic modules

Abstract

The Eco-Energy Engineering course for students of Mechanical Engineering at Master level at AGH University of Science and Technology in Cracow is predominantly theoretical, with the additional computer-aided projects. In order to improve the quality of the course and make the learning process easier for students, some practical elements were introduced. One of them is the presented laboratory stand for the measurement and analysis of photovoltaic modules. The proposed platform consists of a photovoltaic module, rechargeable battery, variable load, charge controller, digital thermometer, solar radiation sensor, and measuring circuit. All the measured variables are stored on the SD card. Also, PC can be connected via the USB port. In order to make the teaching more dynamical, this stand was designed as mobile and it does not need an external power supply. A prototype of the stand was built and tested in real conditions during laboratory classes. A positive feedback from students showed the correctness of the proposed learning schedule and the didactic potential of the laboratory stand.

Pengembangan Database Sistem Pemantauan Daya Panel Surya Berbasis Borland Delphi dan Komunikasi Nirkabel LoRa

“…Meningkatnya popularitas pembangkit listrik energi matahari terlihat dari banyaknya pengembangan pemanfaatan sel surya dalam banyak kegunaan. Dalam bidang pendidikan dan riset terkait pemanfaatan sel surya di fakultas teknik elektro, ini terkait dengan isu tentang teori yang berkaitan dengan mata pelajaran selama perkuliahan [3]. Dengan demikian, teknologi PV merupakan topik perkuliahan dan riset yang ideal untuk mengajarkan konsep dasar kelistrikan dan pembangkit energi listrik sambil memberi informasi kepada mahasiswa, tentang tren teknik saat ini serta mempromosikan teknologi energi terbarukan.…”

Long distance wireless fault diagnosis for photovoltaic modules based on back propagation neural network

“…Back propagation (BP) neural network is one of the most maturely studied neural network algorithms; it has good self-learning, self-adapting, robustness and generalization ability. [12][13][14] As a consequence, taking the actual experimental data into the trained BP neural network, the corresponding fault types of PV modules can be accurately judged. However, the BP algorithm has some disadvantages, such as poor rate of convergence and easily getting stuck in local minimum.…”
