HPBC (Hybrid Passivated Back Contact) solar cells, are the latest solar technology that introduces unobstructed front shading by metal contacts. This pioneering approach optimizes photon collection, resulting in enhanced conversion efficiency. The HPBC cell sets a new industry standard, significantly enhancing light absorption and photovoltaic conversion capability, resulting in substantially improved module power output.

The result is panels capable of generating more energy under higher temperatures and lower light. Some studies have shown that that HPBC cells can produce output up to 10% higher under the same conditions as PERC products.

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.

LONGi is a leading manufacturer of high-performance solar panels, with a strong market position and a global presence in over 30 countries. LONGi Solar is recognized as a top-tier solar panel manufacturer, and is considered a reliable and high-quality supplier of solar panels. The term "Tier 1" is used in the solar industry to refer to solar panel manufacturers that are vertically integrated, meaning they produce the majority of their own solar cells and have control over their supply chain.
