<p><P>PROBLEM TO BE SOLVED: To easily diagnose a power generation state of a photovoltaic power generation panel. <P>SOLUTION: A pair of LED lamps 202 are powered by two adjacent photovoltaic power generation panels 104 and made to emit light equally to each other when equally powered. Thus, the pair of LED lamps 202 are adjacently arranged to compare their illumination states, and correspondence relations between the pair of LED lamps 202 and the two photovoltaic power generation panels 104 are symbolized (by making colors of the pair of LED lamps 202 different to give meanings to the colors, by literation, or by giving meanings to arrangement positions and so on), thereby visually determining a photovoltaic power generation panel 104 having decreased in power generation amount. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
