摘要： 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.

摘要： A semiconductor ceramic contains erbium as a semiconducting agent in primary components of barium titanate, strontium titanate, lead titanate and calcium titanate, with the average grain diameter of the semiconductor ceramic exceeding about 5 &mgr;m but not exceeding about 14 &mgr;m. Further, the semiconductor ceramic contains as additives a compound containing Er with the Er being more than about 0.10 mol but no more than about 0.33 mol, a compound containing Mn with the Mn being about 0.01 mol or more but no more than about 0.03 mol, and a compound containing Si with the Si being about 1.0 mol or more but no more than about 5.0 mol, per 100 mol of the primary component. Thus, a semiconductor ceramic and positive-temperature-coefficient thermistor can be provided with high-flash-breakdown capability, excellent results in ON-OFF application tests and few irregularities in resistance values.

摘要： In order to extract maximum power from a solar cell, maximum power point tracking (MPPT) control is performed under ordinary circumstances. If the output current of the solar cell becomes too small, the operating point of the solar cell is caused to fluctuate over a range wider than that of MPPT control at a period longer than that of MPPT control and the output voltage and current of the solar cell is sampled. In a case where it is indicated by power values obtained from the sample voltage values and current values that a plurality of maximal points of power value exist, a voltage value corresponding to a power value indicative of the largest value is set as the operating point of the solar cell.
