A solar cell module has an outermost surface comprising a surface member on the light receiving face side of the solar cell module, a back face comprising a back face member on the non-light receiving face side of the solar cell module, and a photovoltaic element between the surface member and the back face member. The solar cell module is characterized in that it has a porous incombustible member having a structural strength between the photovoltaic element and the back face member. A solar cell-bearing roof and a solar cell power generation system in which the solar cell module is used are also disclosed.

An installation structure of a solar cell module array in which a plurality of solar cell module strings are arranged on a desired installation face is provided. The plurality of solar cell module strings have a plurality of solar cell modules. There is an inter solar cell module connection cable to electrically connect the plurality of solar cell modules, as well as a positive string cable and a negative string cable. A non-contacting means is provided such that no contact occurs between the positive string cable and the negative string cable or between the inter solar cell module connection cable and the positive string cable or/and the negative string cable. This solar cell module array installation structure excels in safety. That is, in the array installation structure, the positive and negative string cables are wired in a desirable state so that no electric short occurs between these two cables, even when a fire occurs in the vicinity of the installation face.

When a plurality of solar battery modules are to be connected, terminals formed on the rear surfaces of these solar battery modules are connected by electric wires. This wiring is very cumbersome work, so power output wires from a plurality of solar battery modules get tangled together to cause connection errors. In a solar battery module including a cover member for supporting a photovoltaic element, and a structure support member having a portion which forms an angle or a curved surface with respect to the cover member, an electric connecting terminal is formed at an opening of the structure support member, and a locking member at least partially formed by a continuous body is inserted into the structure support member. In this way, the solar battery module is fixed and/or electrically connected.

Provided are a plug that makes it possible to readily connect a power supply such as a solar battery or fuel cell to an external load or system power and to enhance safety, as well as a power converter and power generating apparatus having the plug. The plug has a movable insulating member for covering the plug electrodes when the plug is connected to an outlet and for exposing the electrodes when the plug is not connected to the outlet. In another example of the plug, the plug has at least two electrodes and switches corresponding to respective ones of the electrodes, wherein the switches are opened (turned off) when the plug is pulled out of the outlet. In still another example of the plug, the plug has at least two electrodes and a switch that is opened/closed in dependence upon the state of the connection between the electrodes and the outlet. When the plug is connected to the outlet, the switch is closed (turned on) to thereby sense the fact that the plug has been connected to the outlet.

A thermistor element with positive temperature characteristic (PTC) has a planar ceramic member with a positive temperature characteristic of which the thickness is greater at its peripheral part than at the center part, decreasing either gradually or in a stepwise manner. Protrusions may be formed along its periphery. A PTC thermistor is formed with electrodes formed on both main surfaces of such a PTC thermistor, each electrode having a lower-layer electrode all over a main surface and an upper-layer electrode on the lower-layer electrode. The upper-layer electrode has a smaller surface area than the lower-layer electrode such that a portion of the lower-surface electrode is exposed at the periphery. The upper-layer electrodes may be formed at the center parts of the main surfaces, exclusive of the peripheral parts or where the protrusions are formed. The lower-layer electrodes may be mostly of Ni and the upper-layer electrodes mainly of Ag.
摘要:
In a method for sorting PTC elements having different resistance-temperature characteristics, a predetermined voltage that allows a current to sufficiently decay is applied to each of PTC elements A and B, and the PTC elements are sorted on the basis of the difference between the times required for the currents passing through the PTC elements B to reach a predetermined value (e.g., 52 mA).
