The potentiometer is used to apply a variable electrical load to the output of the solar panel under test. The diodes can be connected to the solar panel to serve as either bypass diodes or blocking diodes. Access to the potentiometer and diodes is through jacks mounted on the front panel of the test bench. Four other jacks on the front panel of the test bench provide direct access to the output terminals of the solar panel to facilitate connection. Lab-Volt Monocrystalline Silicon Solar Panel The Monocrystalline Silicon Solar Panel consists of two independent photovoltaic (PV) modules mounted on a common metal chassis, as shown in Figure 27 . Each module consists of eighteen PV cells connected in series (the PV cells are in fact separated into two groups of nine PV cells connected in series). Each PV cell is made of a thin rectangular slice of silicon which measures about 1 cm (0.39 in) × 5 cm (1.97 in). Adjacent PV cells overlap slightly (like dominoes) to allow the bottom side of one cell to be in contact with the top side of the next cell, thereby achieving series connection of the PV cells. The uniform color of each PV cell in the Monocrystalline Silicon Solar Panel indicates that the cells are made of single crystal silicon. Such PV cells are commonly referred to as monocrystalline silicon PV cells.

The Solar Panel (Photovoltaic Panel) Discussion 17 Solar Power Figure 27 . The Lab-Volt Monocrystalline Silicon Solar Panel. The Monocrystalline Silicon Solar Panel is designed to be mounted in the Solar Panel Test Bench as shown in Figure 28 . The solar panel is provided with push-lock fasteners that allow the metal chassis to be positioned at various distances from the halogen lamp. Independent access to the output of each PV module is provided via a pair of jacks mounted on the solar panel chassis to allow either series or parallel connection of the PV modules. A multi-pin connector on the solar panel chassis allows connection of the PV module outputs to four jacks on the front panel of the Solar Panel Test Bench in order to allow PV module connection from the outside of the workstation.

The surface of the metal chassis on which the PV modules lie is provided with perpendicularly mounted metal pin and silk- PV module PV cell Upper PV module terminals Lower PV module terminals

The Solar Panel (Photovoltaic Panel) Procedure Outline Solar Power 18 screened angular markers. When performing exercises outdoors, the metal pin allows the orientation to be adjusted so that the solar panel is perfectly aimed at the Sun. The Monocrystalline Silicon Solar Panel includes a potentiometer and a set of diodes. The potentiometer is used to apply a variable electrical load to the output of the solar panel. The diodes can be connected to the solar panel to serve as either bypass diodes or blocking diodes. These components are used when the solar panel is used to perform experiments outdoors.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
