      Explanation of solar terminology:

      Monocrystalline: 

      At LUX Solar we only source mono crystalline panels as they offer the highest efficiency. Mono-crystalline panels are manufactured from a single rod of silicon thus the crystal structure inside the silicon is uniform, with very few impurities. Polycrystalline panels on the other hand are made up of smaller crystal structures that introduce grain boundaries in each solar cell. This causes inefficiencies in the conduction of electrons due to defects associated with the crystal boundary. 

      Half Cut:

      “Half-Cut” also known as “half-cell” technology, means silicon solar cells that have been cut in half using a laser cutter.  This helps reduce power loss from resistance, lowers the operating temperature of the panels, reduces hot spot temperature by 10~20°C, and improves the panels' overall performance in partial shade. 

      PERC:

      Passivated Emitter and Rear Cell (PERC) technology is a solar technology that improves light capture near the rear surface of solar panels and optimizes electron capture.  Although it was first invented in the 1980s by the University of New South Wales, Australia, it has only recently been successfully commercialized at scale.  

      9BB (9 Busbar):

      Busbars conduct the power generated by solar cells when they are hit by photons.  9BB means there are nine busbars in each solar cell.  Back in the day, solar panels used to have 2 busbars, but as technology evolves, the solar industry has been increasing the number of busbars in solar panels, to reduce internal resistance losses and increase cell efficiency.  In short, 9BB solar cells provide greater long-term reliability and performance compared to solar cells with a lower number of busbars.
