<p>PROBLEM TO BE SOLVED: To provide solar power generating apparatus of high safety in which the installation place and the installation method of a solar battery are taken into consideration, and a control method of the apparatus. SOLUTION: An output current of each string is measured at intervals of, e.g. one second (S43). Normalized values A1-A6 are calculated by string current comparing calculation (S44). The values A1-A6 are compared with a current comparing reference value A0 (S45). When any among A1-A6 is lower than or equal to A0, an alarm is outputted, and the count of alarm output time is started (S47). Continuously, an output current of each string is measured at intervals of one second, and string current comparing calculation is performed. When any among, the A1-A6 is lower than or equal to A0 after an alarm output reference time T0 has passed (S48), a part between output terminals of the strings is short-circuitted by closing a switch (S49).</p> |
