Polycrystalline Solar Panels

    Polycrystalline panels use a series of cells in place of the single large cell used in monocrystalline panels. Polycrystalline photovoltaics are less expensive than monocrystalline panels but have a slightly lower efficiency. To create same voltage as a mono-crystalline panel, the size of the polycrystalline panel has to be larger.

    Polycrystalline panels perform better in areas of direct sunlight. Similar to monocrystalline panels, they suffer a disproportionate drop in efficiency due to over shading, also high temperatures (50 degrees Celsius) would reduce the efficiency of the panel. When space is not limited, these are the modules to rely on.
