Abstract
The mega solar plant consisting of a flat solar cell module requires a large land. And power generation is changed with time as flat solar cell has a high directivity. The purpose of this study is to reduce the directivity (effect on the output of the solar position) and compactification (decrease installation area) of solar cell module. The point of view is ramification structure of plant. The plant is getting the energy by photosynthesis. It means that the plant evolves to receive light efficiently. From this, it is thought that the plant is the form which was excellent in a compact and light density. Therefore, if leaf of the plant is replaced by a solar cell, excellent light density can be obtained. The plant have branch structure to get light. To express branch structure, L-system and GA are used in numerical analysis, The optimal solution of the plant form and light density were obtained. Result of analysis, the solar cell module which simulated a plant form is confirmed that light density increased in comparison with the flat solar cell module.
