After the solar cell is fabricated, the single solar cell cannot be used directly as a power source. For the power source, several single cells must be connected in series and parallel and tightly packaged into modules. Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. The role of photovoltaic modules is to convert solar energy into electrical energy and send it to the battery for storage, or to drive the load to work.

PV modules include laminates and PV module frames. The laminate includes a string of battery sheets, and a front plate and a back plate laid on the front and rear sides of the string of battery sheets. The cell string is composed of multiple cells. Multiple cells are connected in series to obtain high voltage, and then connected in parallel to obtain high current. After that, a diode (to prevent current return) is used to achieve power output. Both the front and back plates can be made of glass to protect the string of cells. In order to facilitate the fixing of the front plate and the rear plate to the battery string, respectively, the front plate and the rear plate can be fixed to the battery string through an adhesive layer. The front sheet, cell string and back sheet are laminated by a laminator to form a laminate.

The frame of the photovoltaic module is sleeved around the periphery of the laminate to encapsulate and protect the laminate, thereby increasing the compression resistance of the photovoltaic module and prolonging the service life of the photovoltaic module.

The photovoltaic module frame is installed on the photovoltaic bracket, and the photovoltaic bracket stably fixes the photovoltaic module in a certain position, so that the photovoltaic module can smoothly convert the solar energy into electrical energy.
