RenewableENERGY VarioLAB VarioLAB tables and workstations Teaching and experimental workstation for PHOTOVOLTAIC PHENOMENA Stand with photovoltaic panels and basic equipment The VarioLab teaching station for experiments and teaching photovoltaic phenomena consists of a mobile stand based on the proven VarioLAB+ design. It features a robust construction with sturdy legs, shelves, and a work surface. The entire structure is mounted on a chassis consisting of two pairs of sturdy wheels with brakes for easy handling. The workstation is available in two versions. It is equipped with either a pair of photovoltaic panels or a single panel and a perforated worktop. The panels are suspended on swivel arms, allowing them to be adjusted horizontally at an angle of 270°. This makes it possible to adjust the angle of each panel within a wide range for experimental purposes, thereby regulating the amount of sunlight that falls on them. In the case of the variant with one panel and a perforated board, the perforated board is designed for the installation of additional elements, such as an off-grid charge controller, a battery, a panel with appliances (lamps), an inverter for off-grid power supply of appliances from the battery, or other elements. The entire structure is complemented by a worktop with built-in power resistors with coolers in a box with integrated ventilation. The set is complemented by a sliding rheostat, also installed on the worktop under the photovoltaic panels. The set is complemented by measuring instruments and a light sensor as part of the basic equipment. Parameters and equipment: Workstation width/depth/height: Photovoltaic panel dimensions: Output power of one panel: Power resistor parameters: Sliding rheostat parameters: Photovoltaic system tester that enables category 1 measurements according to IEC 62446-1 and communicates with a PC via Bluetooth. Solar radiation and temperature meter that enables the conversion of measured parameters to STC conditions according to IEC 60891 R

PHOTOVOLTAICSFunction description The VarioLab "Photovoltaics" workstations are primarily intended for practical teaching and experiments in the field of real solar panel installations. The basic characteristic feature of these workstations is powerful solar panels that can be freely rotated horizontally, thereby influencing the amount of sunlight that falls on them. A box with power load resistors (22 Ohm / 50 W) is located on the worktop under the panels. These resistors allow sufficient load to be created on both panels. The resistor set is complemented by a sliding rheostat (100 Ohm / 1.25...
