Polycrystalline cells are composed of multiple silicon crystals, which is a cheaper way to manufacture solar modules. Put simply, these cells are easier for a factory to produce, so they are less expensive. Polycrystalline cells are made by several methods, but most commonly with a cast of molten silicon.
POLYCRETE is a seamless urethane concrete overlay system. It's the ideal solution for commercial kitchens and service areas where a durable, seamless, waterproof, non-skid, anti-microbial surface is desirable.he disadvantage of a vinyl composite floor (VCP) is that it is susceptible to staining and denting. Furthermore, it's not a true seamless floor -- the seams in composite sheet vinyl are heat welded together. Sooner or later, in heavy traffic areas, these seams will break, peal, or bust.
