In the solar battery that used silicon, the single-crystal silicon type solar battery and the polysilicon type solar battery were main currents before.
However, the number of cases into which the ordinary family introduced the photovoltaic generation increased considerably in recent years, and the influence existed, too the demand for the single-crystal silicon type solar battery decreased on the cost side, and a cheaper technology came to be requested.
Having given birth in shape to answer it is a thin film silicon type solar battery.
The thin film silicon type solar battery that is called an amorphous silicon type uses very thin “Film of silicon” as its name suggests.
The film of silicon is deposited to the glass substrate etc. , and the amount of silicon is suppressed to about indeed 1/100 compared with two of the crystal types by the method of using it as a base.
It will be able to be said that the thin film silicon type solar battery is a commodity in the silicon type solar battery whose expensive silicon is a problem on the cost side that achieves a very big cost reduction.
However, the electric conversion efficiency is inferior to two of other crystal types, and a figure named 7?10% while the cost side was considerably suppressed.
This conversion efficiency enters a considerably low class in the solar battery.
Therefore, when the solar panel is set up, the possibility that the amount of power generation hits a rough spot cannot be denied according to the environment and the area.
However, there is a merit that the irregularity of the amount of power generation only that the price is not suppressed like it by the temperature change also that is the weak point of the solar panel is suppressed to the minimum in the place where it seems to be a fault, too.
It will be able to be called a solar battery that attracts attention most in recent years.

The one “Polysilicon type solar battery” exists as a solar battery using silicon as well as the single-crystal silicon type solar battery, too.
In the polysilicon type solar battery, the point to use silicon with a small particle of the crystal is a feature compared with the single-crystal silicon type solar battery.
You may actually be different the feature and the cost, and think another solar battery completely though almost look similar on the character side.
The power generation efficiency for each single area is inferior to the single-crystal silicon type solar battery though it is such a polysilicon type solar battery.
However, the cost side of the amount material doesn’t hang from the single-crystal silicon type solar battery, and be cheap.
In addition, when manufacturing it, the cost of manufacturing can be saved because the amount of energy necessary for is also a little.
In a word, the popular edition of a book of the single-crystal silicon type solar battery becomes.
As for importance in the solar panel, the point of using natural energy is enumerated in the first.
It is a point like safety and responsible concern for the environment, etc.
However, these need not already be considered because it is a precondition at the comparison in the same photovoltaic generation and the same solar panel.
Therefore, it is a price, and [attaritoiu] [bu] becomes an object of comparison by the performance.
Especially, the cost possesses great significance very much for the ordinary family.
The demand for the polysilicon type solar battery is high in such a meaning, and it seem to be in the increasing tendency in recent years the amount of manufacturing.
The polysilicon type solar battery is the most excellent in case of say in the point of economic efficiency commodity in the solar battery with the number.

It was the one of the type “Single-crystal silicon type solar battery” that was researched first in that situation though it was a solar panel by which it spread considerably now, and the kind also became abundant.
In the single-crystal silicon type solar battery, the wafer of the silicon monocrystal is made a base, and the point to take pride in a very high though it is the oldest solar battery conversion efficiency is a feature.
Therefore, efficiency of making sunlight electricity is high, and the share is considerably improving.
Moreover, it will be able to be said that reliability is also high because it has an old history.
However, it rises considerably in respect of cost of manufacturing because a very expensive material of silicon crystal is used on the other hand.
Naturally, it enters an expensive by all means class as a commodity because the sales price becomes improving compared with other solar batteries, too.
The point that it costs much somewhat becomes a problem as a solar panel that the individual buys though it is still good for the amount that the corporation uses.
Because the flow of cost reduction is remarkably seen in the field of the photovoltaic generation in recent years, the single-crystal silicon type solar battery is expected that the occupation rate will decrease gradually.
The cost reduction of the solar battery unit might be a reason why the point of difficulty is the maximum because it doesn’t go not to use the silicon crystal.
However, the historical value seems for the existence not to disappear even if being decline high in the future because of the fact that it is a solar battery by which the human race started it first.
All solar batteries with the number started here.
Let’s learn the solar panel.

It is a solar panel if it is said that it is not possible to lack it absolutely in generating electricity by using sunlight.
What many are displayed the solar battery accurately and made like the panel is a solar panel though the solar panel is often called “Solar battery”.
Therefore, there might not be hindrance if it is thought, “Set of solar panel = solar battery”.
The solar panel is a system of the photovoltaic generation, and conversion into electricity is done in this panel.
However, the photovoltaic generation cannot be done in case of being the so much.
The solar battery should connect each other electrically and is indispensable at the same time to connect with other systems.
Therefore, various peripherals are needed.
It is dangerous that the price only of the solar panel is seen, and expenditure necessary for the photovoltaic generation unites the budget by thinking like this.
The feature of the solar panel is that “It is fragile” and the kind are abundant.
It gives birth to interference from all the outside to the cause of the breakdown, the performance, and the decrease in longevity because it is an equipment with a very delicate solar battery.
Therefore, it is necessary to pay close attention to transportation and the installation.
Moreover, when the hard one like hail falls after setting up the solar panel, the possibility of breaking down cannot be denied.
Basically, it is a caution needed in the vigorous stimulation any more though the stimulation such as the rainfalls and the snowfalls is firmly guarded.
The kind is included and abundant reasons include the point that it is a technology on the way for development.
It is a current state not decided of the one “This” yet.
However, there is a difference considerably for diffusion because the solar panel that has started in life now advances considerably, and is trained gradually.
The power generation efficiency is unstable.

“Cannot you generate electricity well in case of the photovoltaic generation on the day of the overcast day and rain?”
Perhaps, it seems that a lot of people think the photovoltaic generation to be uneasy.
This is that’s right if it says from the conclusion.
The amount of power generation decreases by all means when it is cloudy weather and rain compared with fine weather.
Moreover, electricity cannot be generated because the solar panel is hidden at the snowfall.
Naturally, power generation becomes improper at nighttime when sunlight is not irradiated.
These are roads because it makes sunlight energy that cannot pass when avoiding it.
And, there is a matter from which power generation with another point and the solar panel is controlled besides the weather.
It is “Installation environment” and “Temperature. ”
First of all, the point “Angle of incidence degree of sunlight” becomes important though it is an installation environment.
The angle of the ideal might not have a lot of houses that can be set up according to this ideal so for the direction of due south while an angle of the roof or an environmental side of direction being controlled though is a position of 30 degrees in the tilt angle.
In most houses, it will grope for shape near it though it is not an ideal.
On the other hand, there is a characteristic that the power generation efficiency decreases at the high temperature it for the temperature.
Therefore, winter becomes better than that of the south the power generation efficiency of the north than summer.
However, the difference doesn’t actually arise so much in the amount of power generation each day for this respect.
Because the time of summer from which the sun has risen is longer than that of winter.
Therefore, the difference between a hot weather area and a cold region consequentially becomes it with the one minute even in case of being in summer and winter because summer is longer at the exposure time of sunlight though is better the winter of efficiency each unit time.
Initial cost is high.

Up to now, there is a problem of initial cost in the background in which a quite a photovoltaic generation rapid spread was not able to be accomplished.
It is thought that it is still high though it is a photovoltaic generation that can be considerably suppressed for the running cost for initial cost, and there room for improvement.
When the photovoltaic generation is introduced, 150?3,000,000 yen is a market price in the amount of necessary initial cost.
The width of this amount of money is caused by the scale of the solar panel in the range that the ordinary family uses.
However, it is considerably large amount of money, and there might be a place where the installation by small amount is reversely expressed according to the manufacturer because it is not a technology that generalizes still completely, too.
The doubtful one is a credibility of the manufacturer that expresses the price that deviates from the market price.
Such a problem was a lot of the fields in the photovoltaic generation especially especially that were though the shadow of fraudulent sales was seen by may always say by you in a technology on the way for development.
However, it is a past form to the last.
Then, the worry that hangs to unscrupulous dealer’s poison fang is a situation that hardly does and is safe in which a lot of major manufacturers have entered in completely lost of fraudulent sales as long as this , need not be dressed, a high selection of the risk be done, and the range of the market price is suppressed though is not.
However, there might be room for consideration in the point with considerably high initial cost.
It is certain that the cost costs much even if the photovoltaic generation sees compared with other power generation methods for the long term when the electricity fee for each unit is calculated adding initial cost and the running cost.
I will have costing money to set up the solar panel like it in mind.
There is longevity in the solar panel.

Only not that though it is a photovoltaic generation with a lot of advantages is a fact.
If there is an advantage, it is the one where the disadvantage exists, too, and even if it is a photovoltaic generation, it is not exception in what though it is so.
The important one is to hear of the content of the disadvantage, to compare with the advantage on that, and to compare it with other power generation methods.
Moreover, the disadvantage is not necessarily permanent, it will be improved in the future because the photovoltaic generation is still a technology on the way for development, and, according to circumstances, there is a possibility not complete either.
Let’s verify the disadvantage of the photovoltaic generation based on such respect.
First of all, we will strongly recommend the longevity of the solar panel to be known rather than the problem, that is, the feature.
It is not the one that the solar panel moves permanently like being so all equipment, too.
The service life exists.
Then, 20?25 year is a rough standard with very much on earth.
However, this is longevity of the solar panel to the last.
It is necessary to see about ten years for the peripherals.
By the way, peripherals indicate the cable and the power conditioner, etc.
Therefore, there is not necessarily security of having it for 20 years when thinking with the entire solar heating system.
However, the cost necessary for the substitution such as cables is not too high.
The period of ten years becomes a standard to the end in respect of safety.
The state when electricity is generated is steady.

Power generation can think like considerably large scale work.
Actually, a lot of people are witnessing the appearance of the nuclear plant when a East Japan great earthquake is reported, and the appearance of the large scale power generation done in the huge facilities might be established as the image.
However, that is the one only of facilities where that of nuclear power generation also invents a huge amount of electricity to the last.
Power generation need not necessarily be always large scale.
Actually, because the photovoltaic generation generates electricity by a very simple structure, it is done solemnly by the work done in small compass.
Because the element that this respect can become an advantage can generate electricity quietly, it is a point that the trouble doesn’t hang to a surrounding house.
For instance, it is possible not to use easily according to the environment if it is a device that should sound the loud sound when heat is invented like the boiler at the previous state of the person of yore and to exist enough.
However, there is not this in the photovoltaic generation at all.
There are neither a noise nor a vibration at all while power generation is being done with the solar panel, and electricity is being invented by a quiet thing.
Therefore, the solar panel can be set up without trouble even in the place where the house like the residential area has been overcrowded.
Moreover, there are neither waste, drain nor an exhaust that arises when electricity is generated in case of sunlight.
It can be said that this is a favor for which natural energy is used.
Viewpoint..advantage..provide..above all..surroundings..trouble..all..take..respect..home..possess great significance.
