Mobile WebSiteWhy is there a deviation of the color of solar panels? This problem not only once confused photovoltaic people, but also many users of the installation of photovoltaic power system doubts, do not know whether it will affect the use of photovoltaic cells why there will be color differences.
In fact, the color of solar cells are mainly affected by cashmere flake, red film and part of the film.
The overall appearance of the component
1. As a whole, the surface color of the battery inside the same batch of components should be uniform, with no obvious color difference, broken gate, defect damage, spot oxidation spots and so on.
2, Each component in the string of cells and interconnects welded together neatly, welding without deviation, the spacing between the battery strings evenly, no significant deviation, the surface without solder tin, oxidation phenomenon.
3, There is no bubble or delamination phenomenon in the sealing layer of the component, the level is clear and transparent, the interior is free from dirt and no noise.
4, the aluminum frame components should be clean and no corrosive spots, compact interface no obvious cracks, sharp, burr.
5, the edge of the silicone seal should be evenly without local plastic phenomenon.
6, junction box logo clear, strong adhesion, tie buckle well intact.
Photovoltaic backplane
Backplane surface is clean, smooth, clean, colorless and variable. No foreign body surface, dirty, water marks, folds, bumps, bulging, scratches; no obvious gap between the back and the glass edge.
PV junction box
Junction box with a non-erasable logo: product type, manufacturing materials, voltage levels, waterproof level, the polarity of the output, warning signs;
Appearance: the surface of the frame is neat and smooth, no damage, no chromatic aberration, no scratches, no obvious dirt, residues of silica gel, etc .; with complete wiring holes and mounting holes, the length and the position are correct;
Scratches, scratches (including corners), mechanical marks, crater, pitting, peeling, corrosion, bubbles, watermarks, oil marks, and dirt and other phenomena;
