Solar power generation is a method of generating electricity that takes advantage of a phenomenon of electricity being generated when light strikes silicon semiconductors and other materials. Since we will never run out of sunlight no matter how much we use, it is widely accepted all over the world, and is the most installed renewable energy in Japan. Renewable Japan is dedicated to development, power generation, operation and management of solar power plants.
Silicon solar cells, which are the mainstream today, have a structure with two types of semiconductors having different electrical properties, known as “n-type” and “p-type” semiconductors, in layers. When these cells are exposed to sunlight, electrons (-) and holes (+) are generated. The electrons are attracted to the “n-type” semiconductor side (front side) and the holes to the “p-type” semiconductor side (back side), which causes electric current to flow when a load, such as a bulb or motor, is connected to the electrodes on the front and back sides.
From searching for potential sites, to the management after commercial operation, we conduct all the phases for a project.
