The photovoltaic panel of the company Aca is polycrystalline, which means it is made up of multiple fragments of silicon, unlike the monocrystalline panel which has only one crystal. Since there are multiple crystals in each cell, there is less freedom for the electrons to move. As a result, polycrystalline solar panels do not have better performance than monocrystalline panels, but they are more economical.

• Maximum Power: 20W
