This method for detecting a poor module-mounting-state in a concentrator photovoltaic apparatus includes: photographing a surface of an array by an imaging device; obtaining an image in which a virtual image, magnified through a condenser lens, of a light receiving portion including a cell and a vicinity thereof is formed, and a collection of pixels of the virtual image forms a composite virtual image of an entirety of the light receiving portion, the composite virtual image being projected over a plurality of modules; and detecting a poor module-mounting-state based on a form of the composite virtual image.

Method for detecting poor mounting state of module, and array

A concentrator photovoltaic module includes: a concentrating portion configured by arranging a plurality of Fresnel lenses that concentrate sunlight; a plurality of power generating elements arranged at positions corresponding respectively to the plurality of Fresnel lenses; a plurality of ball lenses corresponding respectively to the plurality of power generating elements and guide the sunlight concentrated by the plurality of Fresnel lenses to the plurality of power generating elements; and a housing that contains the plurality of ball lenses and the plurality of power generating elements. The housing includes a resin frame body, and a metal bottom plate that is fixed to the frame body, and on the inner surface of which the plurality of ball lenses and the plurality of power generating elements are arranged. The groove portion for reducing thermal expansion of the inner surface side of the bottom plate is on the inner surface of the bottom plate.

L-shaped positive electrode bus barand negative electrode bus barare provided along a vertical sideand a horizontal sideof the solar battery module, positive electrode output terminalsand, and negative electrode output terminalsandare led out from the long horizontal side, and a positive electrode box, a negative electrode box, and the like are provided to the long horizontal side. In addition, all solar battery cellsof first and second rows Rand Lare connected in series by using only one connection bus bar. Accordingly, even when the positive electrode box, the negative electrode box, and the like are provided to the long horizontal sideof the solar battery module, the number of bus bars is small and the number of connection processes such as soldering is also small.
