SOLAR POWER GENERATION MANAGEMENT APPARATUS

摘要

A solar power generation management apparatus which manages a solar power generation system includes: an output sensor that senses respective output current values or output voltage values of a plurality of unit power generation modules; and a calculator that receives sensing information from the output sensor and displays it on a display (50). The calculator acquires the sensing information of the output sensor and simultaneously displays a plurality of display frames (212) corresponding to the plurality of unit power generation modules on the display. Furthermore, it sets a color level of information displayed in the display frame (212) correspondingly to a level of the sensing information. As a result, operating situations of the plurality of unit power generation modules can be visually monitored based on the color levels in the display frames on the display, which enables maintenance timing of solar panels to be visually recognized.

1. A solar power generation management apparatus which manages a solar power generation system using a plurality of solar panels, comprising:
an output sensor that senses respective output current values or output voltage values of a plurality of unit power generation modules, taking any of a single solar panel and a panel group composed of a predetermined number of solar panels as a unit power generation module; a switching device that switches output lines of the unit power generation modules so as to connect them to any of a power selling-side line and a power storage-side line; and a calculator that is connected to the output sensor and receives sensing information from the output sensor to display an operating situation of the solar power generation system on a display, wherein the calculator
has sensing information acquisition means that acquires the sensing information of the output sensor,has switching control means that controls the switching device using the sensing information,has display management means that simultaneously displays a plurality of display frames corresponding to the plurality of unit power generation modules on the display,has display color setting means that sets a color level of information displayed in the display frame correspondingly to a level of the sensing information acquired by the sensing information acquisition means, andenables operating situations of the plurality of unit power generation modules to be visually monitored based on the color levels in the plurality of display frames on the display, and the switching control means refers to a power selling upper limit value of the power selling-side line and selects a part of the unit power generation modules out of the plurality of unit power generation modules to connect them to the power selling-side line such that a total output of the plurality of unit power generation modules is approximated to the power selling upper limit value, and meanwhile, controls the switching device so as to perform switching such that a remaining part of the unit power generation modules is connected to the power storage-side line.
