<p><P>PROBLEM TO BE SOLVED: To provide a small-sized and highly-efficient solar power generating apparatus capable of taking out the maximum power under the sunshine condition from the entire solar cell group at all times even under an uneven insolation condition to a solar cell, and obtaining high voltage output without increasing a boosting ratio. <P>SOLUTION: The solar power generating apparatus includes: a solar power generation array 1 for which the output terminals of a plurality of solar cell modules 10 are arbitrarily connected in series/parallel, the solar cell module 10 including the solar cell group 11 composed by the series connection or series/parallel connection of one, two or more solar cells, a DC/DC converter 12 which boosts or lowers and outputs both-end voltage of the solar cell group 11 and is capable of controlling a boosting/step-down ratio, and a maximum power point follow-up control part 13 for variably controlling the boosting/step-down ratio of the DC/DC converter 12 corresponding to the power generation output of the solar cell group 11 so as to obtain the maximum power; and a load device 2 which is supplied with the generated power of the solar power generation array 1 and controls at least one of the output voltage and output current of the solar power generation array. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
