Mechanism of photovoltaic generation
The photovoltaic generation makes electricity by using the energy of the sun. However, the day of rain and the day when it became cloudy come to be worried as a simple doubt how it becomes it.
The photovoltaic generation for the house sets up the solar battery in the roof of home, and invents the biography necessary for life. However, electricity is not provided for oneself at home alone. When the sun blazes brilliantly by connecting it with the business electric power that the electric power company supplies electricity, and electricity to which electricity is generated remains, it sells it to the electric power company. This is called selling of electricity to a power company. On the other hand, when the amount of power generation such as the overcast days and the days of rain is insufficient, electricity is bought from the electric power company up to now. This is called a purchased power. Thus, the photovoltaic generation is a reasonable system that can buy securing a steady electric power and an excess amount.
Please supply the requirement from the electric power company when it supplements with the electric power of the electric power company when the light of the sun such as the days of the morning and evening and cloudy weather is weak because it is being supported by such a system, and the amount of power generation of the solar battery such as rain and nighttime is near almost 0. In addition, the work of the electric power company is not disturbed because the system that moves an electric equipment directly is in order while blacking out besides a usual electrical system if there is shooting on the day when blacking out. Therefore, life can be continued regardless of the power failure. This is said, “Self-sustaining function”. However, because the connection to the commercial electric power system is automatically separated once when blacking out, it will switch to the self-sustaining by hand power.
