At LUX Solar we only source monocrystalline panels as they offer the highest efficiency. Monocrystalline 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.

Busbars conduct the power generated by solar cells when they are hit by photons. 5BB means there are five busbars in each solar cell. 10BB mean there are 10 busbars in each solar cell. Back in the day, solar panels used to have only 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.
