Understanding Current Classification in Solar Panels: H, M, and L Labels When it comes to solar panels, you may have noticed labels such as "H", "M", and "L" on their packaging. These labels indicate the current classification of the individual solar cells within each panel. However, it’s important to clarify that these classifications (H, M, and L) are not a reflection of the quality of the solar panels themselves. Instead, they are crucial for ensuring that the panels within each box (typically containing 33 or 36 pieces) have cells with matching current levels. In summary, the H, M, and L labels help maintain consistency and efficiency during installation, ensuring that the performance of your solar system is maximized.
