A Mono (or singular) solar panel is made from a single silicon bar and cut into wafers. A Poly (or numerous) is made from fragments of silicon melted together. Put simply, a Mono Cell is more expensive to make. There’s a misconception that this is better quality. It depends highly on the manufacturer’s quality processes. We focus more on a quality manufacturer, if you have ample roof space, a top quality Poly panel system will just take up more roof space.
