In terms of performance, mono solar panels are more efficient because monocrystalline silicon cells allow electrons to flow freely through the cell. For example, a 1 square foot monocrystalline solar panel produces more electricity than a 1 square foot polycrystalline solar panel. This is especially useful for rooftop arrays where space is limited to build the system.

More efficient panels also mean you can buy fewer panels to meet your target output, and fewer panels translate to lower installation costs. The fewer panels you install, the less you spend on installation materials and labor.

After manufacturers produce their monocrystalline panels, the remaining silicon waste is melted down and mixed to create polycrystalline solar panels. Concentrated solar panels are less efficient due to the drawbacks of the hybrid nature of solar cells.

Also, polycrystalline solar panels are in limited supply because they are a by-product of monocrystalline panels. A limited number of polycrystalline cells are usually reserved for the production of smaller solar panels better suited for RVs and boats, which makes sense since space efficiency is a huge issue for portable solar applications.

While you can still find full-size polycrystalline solar panels, they are becoming less common as the industry trend moves toward more advanced monocrystalline technology. Even if you can find them, if one of your panels fails down the road, it can be difficult to find a replacement.
