Features of LONGi Hi-MO 6 Explorer Panels

As a Tier 1 supplier, LONGi has been producing innovative, high-quality panels since 2000. The brand is a global pioneer in new cellular technologies, ensuring an excellent power guarantee.

LONGi solar panels have undergone extensive testing to maximise yields in a variety of environments and weather conditions. Thanks to Low LID (Light-Induced Degradation) Mono PERC technology, annual power degradation is minimised, ensuring maximum yield over an extended period. You can see this in their excellent warranties.

Full black solar panel

This solar panel is available in full black, also known as pure black. In this version, the frame, cells and back sheet are completely black. All-black panels work better in full sun, but may have a slightly lower efficiency due to higher temperatures. Generally, the difference in performance compared to panels of different colours is negligible, and the choice of colour is mainly a matter of personal preference.
