This solar panel transparent film is a type of device that is designed to convert light energy into electrical energy (through the photovoltaic effect) and is composed of micron-thick photon-absorbing material layers deposited over a flexible substrate. It can generate electricity even at low light levels using a second generation technology. The product is available in transparencies up to 80% with a maximum output of 90 watt per piece. It can function on ambient light levels and it is very sensitive to light. It is also full waterproof and available in various colors. This solar panel film can be installed on existing windows or installed as a stand-alone structure in a building under construction. The standard size dimensions of each solar panel film are 120 cm X 0.60 cm but the dimensions can be customized according to the needs of each client. The solar panel film can generate power even in dim environment, widely applied for roof and window BIPV system.
