Monocrystalline solar panels contain cells cut from monocrystalline silicon ingots. The components of these cells are purer because each cell is made from a single piece of silicon.

    Therefore, the efficiency of a single panel is slightly higher than that of a multi-panel. They also perform better in high heat and low light environments, which means they will produce an output closer to their rated output in less-than-ideal conditions.

    However, they are more expensive to produce and the higher cost is passed on to the buyer. Mono panels are a bit more expensive than multi-panels of the same wattage.

    The single-panel manufacturing process is also more wasteful than alternatives. The single panel is cut from a square silicon wafer with the corners shaved off to create the unique cell shape shown below. Finally, the single panel has a uniform black appearance because the battery is made from a single piece of silicon. I personally think these look better than poly panels, but obviously, it's just a matter of preference.

    Most solar panels deployed today are made from monocrystalline or polycrystalline solar cells.

    There is also a third type of solar technology, called thin-film panels, typically used in large utility projects and some specialty applications. Thin-film panels are made by depositing a thin layer of conductive material on a backplane made of glass or plastic.

    Thin-film panels are generally not used in residential installations because they are far less efficient than single- or multi-panel panels. Because roof space is at a premium, residential customers opt for more traditional crystalline silicon panels to maximize the available space for production.

    However, thin-film technology is less expensive to manufacture and is a more cost-effective option on a larger scale. For commercial and industrial projects without any space constraints, the inefficiencies of thin-film technology are not critical. In these cases, thin-film panels often end up being the most cost-effective option.

    Also, if you've ever seen flexible solar panels on an RV or boat, thin-film technology is what makes these possible.

    Because they are much thinner than conventional silicon wafers, thin films can be deposited on plastic to make flexible solar panels. These panels are especially good for RVs and mobile equipment when you may not have a flat surface to install the panels on.
