<p><P>PROBLEM TO BE SOLVED: To perform efficiently melting snow by a solar cell, and improving durability of an electric power conversion means. <P>SOLUTION: The solar energy power generation system with melting snow function is equipped with a solar cell array wherein a plurality of strings constituted by connecting a plurality of solar cell modules in series are connected in parallel, a switching means capable of opening and closing which is installed for each of the strings, and a control means for performing individually opening and closing of the switching means. The strings can be connected with an external power source through the switching means. The switching means is closed by the control means, and a current is applied to each string one by one from the external power source. By making the strings become feverish, snow laid on surfaces of the solar cell modules is dissolved. The control means opens and closes the switching means in such a manner that electrified time to the strings this time and electrified time to the strings next time are overlapped with each other. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
