Photovoltaic modules (solar panels) are composed of glass,EVA,solar cells,frame,junction box with MC4 connector and so on.

The current and voltage of a single solar cell are very small, we connect them in series to get a high voltage, then parallel to get a high current, then through a diode (to prevent current from being transported back) and output them.
