DERIVING METHOD FOR HEIGHT POSITION FOR MOUNTING PHOTOVOLTAIC POWER GENERATION MODULE, MOUNTING METHOD FOR PHOTOVOLTAIC POWER GENERATION MODULE, AND PROGRAM FOR CALCULATING HEIGHT POSITION FOR MOUNTING PHOTOVOLTAIC POWER GENERATION MODULE

摘要

PROBLEM TO BE SOLVED: To provide a deriving method for height position for mounting a photovoltaic power generation module that makes it possible to mount the photovoltaic power generation module at a position the module is less affected by a shade of a lateral member in a case where the photovoltaic power generation module is provided on the inside of a translucent wall, and also to provide a method for mounting a photovoltaic power generation module, and a program for calculating a height position for mounting the photovoltaic power generation module.SOLUTION: A deriving method for a height position for mounting a photovoltaic power generation module comprises: an annual solar insolation reception amount deriving step in which a solar light receiving surface is assumed on the internal surface of a translucent wall H according to the height position of the translucent wall H, and an amount of solar insolation annually received is calculated for each position in the direction of height of the solar light receiving surface, taking account of shade formed by a lateral member 3; and an appropriate height position deriving step in which the position Pm at which a rate of change in an amount of solar insolation annually received at a position in each height direction, which is derived by the annual solar insolation reception amount deriving step, is maximum in the height direction is derived. The maximum position derived by the appropriate height position deriving step is the receiving-surface upper end position Y of the photovoltaic power generation module 5.
