In summary, the main difference between monocrystalline and polycrystalline solar panels is the way they are made and the resulting efficiency and lifespan of the panels. Monocrystalline panels are made from a single, continuous crystal of silicon and are more efficient and have a longer lifespan, while polycrystalline panels are made from many small crystals of silicon and are less efficient and have a shorter lifespan.
