Temperature, electrical load, and illumination are the main factors influencing photovoltaic solar cells. With the aid of this equipment, you can carry out focused studies to comprehend the fundamental ideas and effects on cells and modules that are genuinely significant. An adjustable lamp field provides light for four solar cells. With the help of a controlled Peltier module, they may be precisely maintained at a chosen set temperature. The cells can be connected in a variety of ways via a patch panel by using the set of cables that are included. For instance, bypass diodes can be used to bridge individual cells so that variations in power loss, such as those brought on by shaded cells, can be examined. The patch panel has a built-in rheostat for manually recording current-voltage curves. The integrated measuring unit is used to detect voltage and current readings. Software can take automated measurements by defining patterns of electrical load. Corresponding sensors detect temperature, voltage, current, and illumination. The software, which is optional, can show and log this data.
