The photovoltaic module is formed by combining solar cells or solar cells with different specifications cut by a laser cutting machine or a steel wire cutting machine. Since the current and the voltage of the single solar cell are very small, the single solar cell is firstly connected in series to obtain high voltage, then connected in parallel to obtain high current, and then output through a diode. And the glass and the back plate on the back are installed, filled with nitrogen and sealed, and the whole is called a module, namely a photovoltaic module or a solar cell module.

Ordinary photovoltaic module, all fixed, but the sunlight is different at the angle of illumination in one day, and fixed photovoltaic module is high inadequately to the utilization ratio of solar energy to photovoltaic module exposes for a long time, receives various pollutions easily, for example foul such as bird's droppings, dust, if can not in time clean, has influenced battery efficiency more.
