A photovoltaic panel module is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells that are almost entirely made of semiconductor materials (such as silicon). Since there are no moving parts, it can be operated for a long time without any wear and tear. Simple photovoltaic cells can power watches and computers, while more complex photovoltaic systems can light homes and power the grid. Photovoltaic panel modules can be made into different shapes, and the modules can be connected to generate more electricity. Photovoltaic panel components are used on rooftops and building surfaces, and are even used as part of windows, skylights or screening devices. These photovoltaic facilities are often referred to as building-attached photovoltaic systems.

1. Tempered glass: plays a supporting role and provides sufficient mechanical strength for battery components.
 
2. EVA: EVA film is used for packaging battery components.
 
3. Conductive copper tape: made of oxygen-free copper sheared and straightened, with hot-dip coating on all outer surfaces.
 
4. Battery slices. The core part of the battery component is a semiconductor battery sheet that is doped, diffused and fired.
 
5. TPT backsheet: a composite film made of multiple layers of polymer films that are rolled and bonded together to protect and support the battery cells. It has reliable insulation, water resistance and aging resistance.
 
6. Aluminum alloy frame: The solar frame is made of aluminum alloy, which has very good strength and corrosion resistance. It can support and protect the entire battery panel.
 
7. Junction box: outputs the generated electrical energy to electrical appliances or other equipment.

EOC-800 ultra-depth-of-field microscope can measure roughness, height, depth, and flatness, meeting three-dimensional high-precision real-time measurement; 6000-fold magnification, 100-nanometer grating analysis, ultra-depth of field synthesis, and fine full-frame images; Shooting function, high-quality images are presented in real time; automatically read the contour difference to achieve precise automatic measurement, greatly improving detection efficiency; 1:5 large zoom ratio coaxial light source is used for highly reflective objects, such as photovoltaic panels , chips, steel and aluminum materials, wafers, semiconductors and other samples; using 3D modeling, ultra-depth of field image synthesis is suitable for depth measurement of step surfaces, blind holes, grooves and irregular shapes.

2. The E-GJ310 tool microscope is an essential instrument for inspection, analysis and research of electronics, metal materials, minerals, geology, precision engineering, etc. It is suitable for teaching, scientific research, industry and other fields. The EOC infinity optical system is used to perfectly correct various chromatic aberrations and is used for directional observation of conductive particles in products such as TFT/TP/LCM. Programmable LED cold light source (surface light and contour light) enables programmed batch inspection to adjust the intensity of the light source automatically; automatic measurement software can enhance the measurement performance of the microscope and perform complex measurements; create inspection strokes to achieve three-axis sub-micron precision parts, Measurement of electronic components, LED arc ball thickness, etc.


The E series tool microscope extracts the detection surface based on the fast optical scanning module and signal processing algorithm, and performs batch automatic inspection of the grid lines and texture on the surface of photovoltaic cells. Multiple coordinate points can be preset on the sample to be measured, and OK/NG judgment will be automatically made based on the preset coordinate points to start automated measurement. After specifying the XY coordinate position of the test point, use the automatic positioning and focusing of the tool microscope to automatically measure the length, width, and depth analysis of the photovoltaic panel. After the analysis is completed, the measurement of the next designated test point will be automatically started, and the above operation will be repeated until all preset coordinate points are measured. After the test, a data report is automatically generated, and the specific information of each preset coordinate point of the photovoltaic panel can be clearly understood based on the data report information.
