A solar cell assembly including a plurality of solar cells is formed on a common substrate, and a DC/DC converter which converts the output from the solar cell is connected to each solar cell to constitute a solar power generation apparatus. The output from the solar power generation apparatus is converted into an AC power by an inverter and supplied to a load or commercial AC power system. Since the arrangement is simplified, the manufacturing cost can be reduced, and the influence of partial shade or a variation in characteristic decreases.

A solar battery module and its installation method are provided which are good in installation workability, which can shorten a cable, and can match various roof shapes. A distance between an output terminal and the end face of a solar battery module along a line between output terminals of adjacent solar modules is longer upon installation completion of the adjacent solar battery modules than during electrical connection of the adjacent solar battery modules.

AC module makers must prepare two types of AC modules for the 100-V and 200-V outputs only for domestic supply. For foreign countries, the makers must manufacture AC modules compatible with more system voltages. To solve these problems, the control circuit of an AC module controls the operation of an inverter circuit and/or the transformation ratio of a transforming circuit, and ON/OFF-controls a switch on the basis of the system voltage and connection state of an electric power system.

In an inductor having a core and first and second coils wound upon the core, the wire of the first coil and the wire of the second coil lie are wound so as to lie parallel to each other and contact the core. The winding starting position of the first coil is made to coincide with the winding starting position of the second coil along the axial direction of the core and is offset from the winding starting position of the second coil along the winding direction of the core. As a result, the area factor of the coils in the winding area of the inductor can be improved and the size of the inductor reduced.

In the adhesion structure of a box member according to the present invention, the box member adheres to a adhesion surface with an adhesive member, a corner between a bottom surface and a side surface of the box member has a curved portion of a curved shape such that the adhesive member remains between the adhesion surface and the curved portion, thereby providing an adhesion structure of the box member that can readily achieve a larger adhesive strength in a smaller space.

In a transformer assembly formed by using a plurality of transformers each formed by winding a primary coil and a secondary coil around a winding core, one terminal and the other terminal of the primary coil are arranged on opposite sides of the winding core, one terminal and the other terminal of the secondary coil are arranged on opposite sides of the winding core, and N transformers in which the coils and the terminals are laid out are arrayed in the lead-out direction of the terminals of the primary coil while M transformers in which the coils and the terminals are laid out are arrayed in the lead-out direction of the terminals of the secondary coil so as to make a line which connects one terminal and the other terminal of the primary coil cross a line which connects one terminal and the other terminal of the secondary coil.

摘要:
To improve the conversion efficiency of a power converter in a solar cell module in which a solar cell module main body containing a solar cell is integrated with a power converter for converting the output power from the solar cell module main body, a material having small thermal conductivity is used as a member (205) of a protective case for protecting the power converter to be fixed to the solar cell module main body containing the solar cell, thereby preventing easy conduction of heat from the solar cell module main body heated to high temperatures to a power conversion circuit (201). A material having large thermal conductivity is used as a member (206) of a protective case for fixing the power conversion circuit (201), thereby allowing easy radiation of heat generated in the power conversion circuit (201).
