Abstract
A non-sun tracking concentrating solar module composed of solar panels and reflectors was proposed in order to improve the generating performance and its characteristics was evaluated. In this solar module, direct sunlight as well as reflected sun-light was irradiated to the solar panel, as the module is equipped with reflector in front of the solar panels. Outside test data showed this module generates output power 1.5 times larger than that of the conventional ordinary solar modules. These experimental data mean the reduction of number of solar panels by approximately 40% in the photovoltaic systems.
