The solar cell module disclosed herein comprises: a laminate including solar cells; a module frame including a side wall portion disposed to face an outer circumferential side surface of the laminate, a rear wall portion bent and extending from the side wall portion to face the rear surface of the laminate, a front wall portion bent and extending from the side wall portion to face the front surface of the laminate, and a front contact portion extending from the front wall portion so as to be in contact with the front surface of the laminate and having a thickness thicker than that of the front wall portion; and an adhesive interposed between the side wall portion, rear wall portion, and front wall portion, and the laminate.
The present invention relates to a solar power generation system and an operating method thereof. The solar power generation system according to the present embodiment may comprise a module level power electronics (MLPE) device connected to a solar module so as to optimize the output power source of the solar module, wherein the MLPE device includes: an RSD module for rapidly shutting down the output power source of the solar module from being output to a power conversion unit which converts the power source optimized by the MLPE device into a power source that can be supplied to a load and a system or converts a power source supplied from the system into a power source that can be stored in a battery; and a processor which monitors the state of the solar module so as to control that the output power source of the solar module is optimized, and which dynamically controls an RSD function of the RSD module in correspondence to an initial driving time of the MLPE device and a control signal of the power conversion unit.
The present invention relates to a multiple-loop power generation system and method using cold energy of liquefied gas whereby waste cold energy of liquefied gas is recovered and power is generated by using multiple loops. A multiple-loop power generation system using cold energy of liquefied gas, according to the present invention, comprises: a main refrigerant turbine-generator which drives a turbine using a main refrigerant stream and generates power; a main refrigerant branching portion which branches the main refrigerant stream expanded while driving the turbine into two or more main refrigerant streams including a first main refrigerant stream and a second main refrigerant stream; two or more main refrigerant economizers which respectively cool-down the two or more main refrigerant streams, comprising a first main refrigerant economizer which recovers cold energy of the liquefied gas by exchanging heat between the first main refrigerant stream and the liquefied gas; a main refrigerant compressor which supplies a main refrigerant stream that is cooled by any one of the two or more main refrigerant economizers as a refrigerant for another main refrigerant economizer; an auxiliary refrigerant turbine-generator which drives the turbine using an auxiliary refrigerant stream and generates power; and an auxiliary refrigerant economizer which exchanges heat between the auxiliary refrigerant stream that is expanded while driving the turbine and one or more main refrigerant streams discharged after the heat exchange in the two or more main refrigerant economizers, so that the auxiliary refrigerant stream is cooled by the remaining cold energy of the main refrigerant stream.
