In order to more effectively use solar energy, a three-dimensional (3D) photovoltaic module using Fibonacci numbers, hereafter referred to as a Fibonacci numbers photovoltaic module (FPM), has been proposed. In our previous report, it was shown that the power generation of an FPM, which is designed with multiple stages that mimic natural leaf arrangements, exceeds that of a conventional planar PV...
To achieve efficient production of solar energy, a three-dimensional Fibonacci number photovoltaic module (FPM) based on leaf arrangement has been proposed. A power generation woods will comprise a number of such FPMs. In this study, the shadowing effect of adjacent FPMs on power generation is investigated.
Residential fuel cells are expected to become widely used as a measure to decrease the anthropogenic greenhouse effect on global warming. In general, residential fuel cells are individually installed and utilized by a household, and cannot be efficiently used during periods of low power demand. We have examined an adaptive management model, in which the number of operating fuel cells is controlled,...
This paper presents a novel photovoltaic (PV) system that has a one-axis tracking function. This PV system utilizes cheap mirrors, rather than multiple solar cells, to reduce the power generation cost. Based on the principle of mirror reflection that is used to increase illumination on the surface of a solar panel, the system structure is discussed. After analyzing the continuously changing positions...
The economic efficiency of photovoltaic (PV) and battery systems for residential power distribution is evaluated quantitatively for the first time under a rate system using electricity prices that change at hourly intervals (i.e., real-time pricing, RTP). The evaluation model assumes that the option price of a feed-in tariff (FIT) decreases continuously. The proposed operational method focuses on...
