A concentrator photovoltaic is formed by concentrator photovoltaic panels each having solar cells arranged on the back side of concentrating lenses. A plurality of portions of an image are imaged at the periphery of each of the solar cells in each of the panels. When each of the panels tracks the sun to be swung in the right-left direction and in the up-down direction, an image which can be identified through the concentrating lenses by a person who sees the image from a position in front of the concentrator photovoltaic is different according to an angle at which the panel is swung (direction rotation angle and elevation angle) due to the characteristic of the concentrating lenses. Therefore, the image of a letter or the like which appears with movement of the sun can be changed, and a message or the like according to time thereof can be displayed.

Disclosed herein are methods of measuring, adjusting and uniformalizing a sectional area ratio of a metal-covered electric wire, a method of cleaning an electric wire, a method of manufacturing a metal-covered electric wire, an apparatus for measuring a sectional area ratio of a metal-covered electric wire, and an apparatus for electropolishing a metal-covered electric wire. Electric resistance values of first and second materials are previously stored respectively so that a sectional area ratio of a metal-covered electric wire is calculated on the basis of the as-stored values and an actually measured electric resistance value of the metal-covered electric wire. Measurement and uniformalization of a sectional area ratio of a metal-covered electric wire and cleaning of an electric wire are carried out by dissolving surface layer parts of the electric wires by electropolishing.
