As for what we learnt due to a East Japan great earthquake on March 11, 2011, it cannot know several.
And, the problem of electricity stood out in relief as biggest one in that.
It doesn’t only stay only in the problem of nuclear power generation.
It is necessary to have learnt to have to think about the ideal way of the electricity that was able to be put in a time of disaster.
All lifelines were cut, and the region having been overcome by the earthquake and the tsunami was driven in to the predicament.
The rupture of the lifeline destroys modern daily life into which the hot technology is introduced very easily.
Especially, man’s life has become close too much with electricity.
It came to actually face too fragilely, that all information and the amusement were intercepted, and even heating, air-conditioning, and the lighting be deprived if there was no electricity.
However, the life doesn’t rely on is not realistic in ..monopoly.. electricity now.
The power generation method of being able restoration at once even due to the disaster or no rupture rose and the tendency to need it should have risen in the future.
Even if the power failure happens for the photovoltaic generation, electricity can be supplied with an emergency outlet.
Moreover, even if the rupture of the lifeline happens, even the solar panel can safely use electricity without trouble.
It will be able to be said that it is a very big strong point to be able to use electricity in any emergency even though there is a limitation when the solar panel is safety only in daytime.
The photovoltaic generation is a very reassuring power generation method that can be used when the disaster happens.
Electricity cannot be basically saved.
This is a possible only for a small amount of electricity to the last technology though there is a machine that accumulates electricity from a domestic power supply like the battery.
In the ordinary family of the contemporary society that should always turn on the refrigerator and the lighting, it is not useful securing the electric power of being able to cover them for a long time.
Therefore, the electricity invented by the photovoltaic generation cannot be said that it is turned at another time zone even if remaining and it uses it.
However, it is not necessary to take a pessimistic view of it.
It is because there is use equal with it even if it is not possible to save it.
Because the electricity that collects in the solar panel, and remains can be sold to the electric power company.
When the system of the photovoltaic generation is bought, the one electric power company and “Selling of electricity to a power company contract” is connected.
“Power purchase agreement” is exchanged with the electric power company between the ordinary families, and originally, electricity can be bought, and selling it only no purchase it if the contract that electricity can be additionally sold is exchanged becomes possible.
Surplus electricity is basically sold off by the automatic operation in the solar panel.
Therefore, how much electricity was sold is not understood if details are not seen or is asked and can be understood by the selling of electricity to a power company meter ignorantly do not seem.
There is “[Den] ..affording.. meter” in each home, and, as a result, when “Selling of electricity to a power company contract” is exchanged, the selling of electricity to a power company meter is set up there though the electric power used is understood.
Electricity is bought very much if it is seen, and how much it sold it is understood at once.
Because this meter is switched by the automatic operation, the resident in the house need not operate it.
Power generation is based on the theory of turning the one like the motor that is called “Turbine” by using “Power”.
The turbine is turned by using the flow of water, the power of the wind, and nuclear power, etc. , and electricity is invented.
Then, it is actually different whether the photovoltaic generation is also so.
The photovoltaic generation is one of the power generation methods of not using the turbine.
The method of generating this method has not arrived at the generalization of both parties though are other “Vibration power generation” and “Magneto hydrodynamic power generation”, etc.
In a word, the photovoltaic generation becomes a main current power generation method only as non-turbine power generation.
It is a structure of sunlight’s being irradiated to “Photoabsorption layer” made from the semiconductor material, and becoming electricity because “Electron” that exists in the layer absorbs, and activates sunlight if it easily explains the mechanism of such a photovoltaic generation.
However, only because electricity exists it is possible to hold this, it doesn’t become “Domestic power supply” that can be used by the ordinary family.
It is necessary to invent the flow current of electricity.
The one that the system to here was integrated is a photovoltaic generation, and it becomes a solar heating system.
All systems of such a photovoltaic generation are built into the solar panel.
Sunlight is absorbed with the solar panel, and it converts it into the electricity that can be used at home there.
The solar panel only doesn’t collect sunlight, and be a system that converts sunlight into electricity.
This system has a lot of advantages.
Moreover, there is a disadvantage, too.
It is important only that a lot of people know them in the field of natural energy.
The consideration of the Japanese to the one “Power generation” changed in dramatic form since a East Japan great earthquake.
Especially, various information on each natural energy came to reach the ear of a general person after attention came to have gathered in natural energy.
As for electricity, the chance to obtain knowledge by what kind of raw material in what principle it is born has increased.
Attention has gathered in the photovoltaic generation in that because there are various advantages compared with other natural energy.
Then, after such an advantage is based, it introduces the feature of each power generation.
In the power generation done in Japan, five “Thermal power generation”, “Nuclear power generation”, “Hydro-power”, “Wind power generation”, and “Photovoltaic generation” are main currents.
It is still micro existence in the point of practical use though other various power generation methods exist.
Thermal power generation is a method of a lot of adoptions in Japan.
The fossil fuel such as oil is used, and some problems of the influence of the environmental impact and the oil sudden rise etc. are pointed out.
The explanation might be unnecessary concerning nuclear power generation.
In the power generation method put in question most in Japan now, a big doubt is had in the safety.
Hydro-power is a power generation method using “Flow of water” that is natural energy.
There is a limit in the flow of water, and is a problem that it is difficult to cover many though it is very clean, too.
Wind power generation is also similar.
If these energy is made a main current, the system will be developed, and an enormous cost be needed for maintenance.
And, the photovoltaic generation.
It is a power generation method of installing the solar panel, taking sunlight into the solar panel, and converting it into electricity.
Then, let’s see the feature, the advantage or the disadvantage etc. of such a photovoltaic generation.
If it is Japanese, no one can be forgotten.
Such a disaster occurred on March 11, 2011.
It is a large earthquake of magnitude 9.0 that is called “East Japan great earthquake”.
A lot of lives were lost by the caused tsunami and, as a result, a harsh blow was received with the earthquake of the maximum scale in this history of Japan in economic respect.
And, it is “Nuclear accident the first in Tokyo Electric Power Company Fukushima” in fear in Japan to make them shudder above all.
The attitude into the energy of Japan, consideration, and the policy came to be overturned from foundation due to this accident.
Power generation has been basically called a match with the cost.
Nuclear power that had was promoted to a multi amount as a national policy the advantage in the point under the idea of saying by anyway low-cost though it was possible to say also to the entire energy policy.
It was recognized that it was not then good so now however, and the spot came to hit safety and various elements such as prospects.
Then, it is natural energy to have attracted attention.
The system that generates electricity by using natural energy also advances considerably ahead by development, and has advanced also the technology every year.
However, it is a fact, and to have been burying the chance to steal the limelight quite from not reaching in respect of the cost nuclear power.
However, the number of users has increased remarkably in that only as for “Photovoltaic generation” using “Solar panel”.
And, after the earthquake, quite a lot of solar panels came to be set up than before in the roof at each home.
Let’s learn “Photovoltaic generation” to boast of the highest degree of interest in such power generation by natural energy.
