Photovoltaic Modules: Mono/Polycrystalline silicon
The cells of monocrystalline silicon modules consist of a single crystal silicon. In pure silicon atoms are perfectly aligned thereby guaranteeing the highest conductivity. The increased purity of the material ensures a higher return (equal to 15%).
PV cells are very dark blue uniform in color and usually have an octagonal shape with a thickness of about 0.2 to 0.3 mm.
Monocrystalline solar modules are ideal for those who have access to a limited area of installation.
The cells of polycrystalline silicon modules (also called multicrystalline) consist of a complex of silicon crystals, therefore they have a to lower performance, which is between 11% and 14% against 15% obtained using monocrystalline silicon cells.
They are still aggregated together (polycrystalline structure) and have different shapes and orientations. They are characterized by intense blue iridescent colour.
Thanks to new manufacturing technologies and high investment in research and development, production costs have been lowered further and managed to achieve good levels of efficiency.
