LOW CONCENTRATION PHOTOVOLTAIC POWER GENERATION SYSTEM

摘要

PURPOSE: A low concentration photovoltaic power generation system is provided to increase generated energy by irradiating the sunlight of which intensity is higher than the intensity of natural sunlight on a solar cell. CONSTITUTION: A concave refraction mirror (2a,2b) concentrates and refracts sunlight. The width of the concave refraction mirror increases decreases according to the shape of a cylindrical surface. A concave refraction mirror (3a,3b) is arranged in the focal point of the sunlight reflected on the concave refraction mirror. A second refraction mirror reflects the light reflected on the concave refraction mirror. The height of a solar cell is changed according to a position that the sunlight reflected from the second refraction mirror is received.
