There is some how to buy when the solar panel is actually bought and the photovoltaic generation is introduced.
The trouble in that is active sales like the door-to-door selling and the telephone solicitation, etc.
Because it doesn’t move from the purchase side, and such a sales system for which it appeals from the sold trader side has the possibility of fraudulent sales, it is necessary to watch it.
However, the solar panel also is a field that exists in the midst of the spread now, and is by these sales systems and has the situation of standard.
Because the door-to-door selling and the telephone are usually solicited now though it is a healthy trader, posture of excluding everything might be a little violent.
Let’s judge the out at that time when the prompt decision is pressed as how to ascertain it.
The company that hurries the contract will not basically trust it.
When the explanation of making it to cheapness only now is done, it is a precaution necessary.
In that case, the trader of whom the engineer who has knowledge concerning the installation goes is safe though the trader comes after taking the appointment at the telephone solicitation.
On the other hand, the place where the estimate is put out without going up to the roof is NG in complete.
How to buy other than this two include the approach directly to the access and the office by the Internet etc.
It is a case where the purchase side becomes active.
The possibility of here is an unscrupulous dealer might be few.
However, it cannot be said that there is actually not a possibility of back though it is an officially usual company either.
Let’s first examine the reputation of the company on the net etc. , and have two or more companies put out the estimate on that.
It is becoming careful too much the solar panel is shopping of high priced just good.
How to choose enforcement company
Becoming importance the construction company of the solar panel is ascertained is whether to have “Sincerity”.
For instance, the point whether explain without concealing it becomes a big judging material though there are some disadvantages in the photovoltaic generation.
It will be able to be said that the place where it dares to do the remark that becomes disadvantageous is sincere.
The point whether to explain cooling off neatly is also important.
Cooling off is a system that should be called a natural enemy for the unscrupulous dealer.
Therefore, the company that firmly explains this can judge that a safe possibility is high.
Moreover, the point whether there is a detailed explanation concerning the photovoltaic generation is an important point.
When man who doesn’t have knowledge comes too much as sales, you may think that the company is considerably dangerous.
When the enforcement company where the quality or more is high is chosen on that, it might be good to value the point “Proposal power”, “Construction power”, and “Support power”.
The photovoltaic generation is not a system that can do the power generation of the same condition in all homes.
Therefore, the shape of each house and it is necessary to propose it according to conditions of location etc.
When it is not done, it will not be able to be said a too high-quality enforcement company.
Similarly, after setting up the solar panel whether electrical work that constructs the technology and the system when the solar panel is installed can be firmly done, I will examine it hearing the opinion in case of being to be near the point of preparing the steady guarantee system the home using the trader.
Of course, the after following is also important.
When the place followed for ten years or more is chosen because chiefly ten years are standards at the guaranteed term, the photovoltaic generation is safe.
Manufacturer and enforcement company of solar panel
There are a lot of matters that should be confirmed when the photovoltaic generation is introduced.
Importance especially especially the is manufacturer of the solar panel and enforcement company of the photovoltaic generation.
Where is chosen from among the company where the number exists will accompany it means big in the future.
First of all, the main manufacturer of the solar panel includes “Sharp”, “[San;yo-]“, “Panasonic”, “Kyocera”, “Mitsubishi”, “Solar frontier”, “[Hondasorutekku]“, “Fuji Electric Co., Ltd. systems”, and “[Kaneka]“, etc.
There might basically not be worry for these manufacturers in the point of reliability on the safety side.
Both Sharp electric equipment manufacturers are only companies of a top class also in the country.
However, because the treated product is different according to each manufacturer, the feature of the solar panel is different.
For instance, [san;yo-] puts a force upon the HIT solar battery, and CIS system thin-film solar cell of the solar frontier is strong, etc.
It is important to choose the manufacturer after it compares it with the condition at each home etc. because there is a field in which each manufacturer is skillful.
And, importance is how more than this to choose the sales construction trader of the solar photovoltaic system.
It is a company that not the manufacturer it, actually sells the photovoltaic generation and the solar panel, and sets it up in the bought home.
The photovoltaic generation had been called unscrupulous dealer’s hotbed before though it came when considerably decreasing compared with before.
It is necessary to note this respect especially because the remaining influences also is now, and has a doubtful entrepreneur in the inside.
Subsidy system of photovoltaic generation
The subsidy system has been installed in the photovoltaic generation though it has comparatively become a famous story in recent years.
It is actually abolished once in 2005 though this subsidy system started originally in 1994.
However, the necessity of the photovoltaic generation is examined again afterwards, and it has revived since 2009.
The point that the photovoltaic generation is an environmentally-sound technology is very high and it seems that it is evaluated because of the viewpoint of this.
“20,000 yen per 1kw. ” before it abolished it though it was a subsidy system of such a photovoltaic generation.
Basically, because the cost that hangs to the solar photovoltaic system including the solar panel is 50?600,000 yen for each 1kw, it becomes about the entire 3?4%.
It can be said a little lonely figure as a subsidy.
This respect is pointed out as a problem, and as for the amount of money of the subsidy, it goes up gradually, and the review is done every year now.
It became 48,000 yen at the stage of 2011, and it became the amount of money first twice or more.
The subsidy system related to the installation of the solar panel will be discontinued when the amount prepared as a budget is lost.
Moreover, the period can be from April through December, and it not apply at any time all the year round of application.
I will apply for the home where the installation of the solar panel is examined ahead of time because the system might be lost if not applying while there are fiscal resources.
Not only the country but also the municipality might gone originally in the subsidy system of the solar panel.
In that case, let’s inquire of the municipality because there is a case that can be used going side by side with the subsidy system in the country, too.
Advantage and disadvantage of solar panel installation
Basically, the solar panel is the one installing it in the roof.
It might be a part of the roof in most houses that can most efficiently collect sunlight though there is no regulations that it should be a roof.
Therefore, when the solar panel is set up, the hanging of a roof and the area, etc. become conditions of the installation as it is.
However, it is thought that it is an extremely sudden slope as long as it is not a unique house where the design was valued or it narrows and there is no [taritoiu] roof.
There is not so much individuality of the roof for one monger, and a similar condition will almost make the installation possible.
Therefore, there are not so many problems of advantageous disadvantage.
On the other hand, a considerably advantageous point and drawback are clear in the point of surrounding climatic condition.
The reason for the temperature is that it greatly influences it in the installation of the solar panel.
The power generation efficiency falls by the temperature high in many cases though there is an exceptional solar battery, too.
Therefore, it becomes disadvantageous in the region where the temperature is high.
However, it alone is hot where, and doesn’t have the difference very much in the temperature in Japan of recent years if it excludes a part of Hokkaido and Tohoku at the summer time.
Therefore, this respect need not become naive, too.
The problem is a snowy region.
When the panel is hidden by the snowfall, the solar panel cannot generate electricity.
However, to the problem that this is actually big seem few.
As for the solar panel, it is slippery and even if the snow piles on the panel, most snow avalanche [shi] because the snow on the surface melts easily.
Capacity and cost of solar panel
An important thing for choosing the solar battery is a point of adjusting the quantity of electricity used in life and the quantity of electricity to which electricity can be generated with the solar panel to a close value as much as possible.
This swings and the life base will swing if the amount of power generation of the solar panel is a little.
As for the respect, there might be a lot of homes that it wants to stabilize life at cost in the early the minimum if possible because the amount of power generation can sell the surplus electricity to the electric power company in an excess case though worry is unnecessary.
The point to have to pay attention most when buying it in such a meaning is capacity of the solar panel.
The capacity of the solar panel is proportional to the amount of power generation.
In a word, largeness can make a lot of electricity.
It is “Relation between the installation capacity of the solar panel and the quantity of electricity necessary for life”, and “Cost for each 1kw. ” becoming important here.
Isn’t there hindrance in daily life if it is installation capacity of how much solar panel?
How much is cost in the unit capacity?
It is likely to come not to lose greatly at initial cost if these two points are suppressed.
In general, it is said that the electricity of the amount in which the obstacle doesn’t exist in daily life can be secured if the installation capacity of the solar photovoltaic system is “4kw” for the home where it lives by four people.
However, this is an average to the last figure.
No so much use of the air conditioner, and the refrigerator is small, and it is “3kw” and there is a safe case if it is a home of not so using the lighting, too.
On the other hand, the market price of cost for each 1kw is assumed to be about 50?600,000 yen.
Therefore, initial cost that hangs to the solar photovoltaic system used by the ordinary family is installed within the range of 150?2,500,000 circle.
How to choose solar panel
Which solar battery should I select when the solar panel is set up though it is a photovoltaic generation where the solar battery of a variegated type exists?
Of course, because each solar battery has the feature, judging it after my favor, environment, and economical situation, etc. are seen is the best.
However, being not able to do it for the person who introduces the photovoltaic generation for the first time easily might be a fact.
Then, it some introduces how to choose the solar panel.
When the solar panel is chosen, the point that should be valued is two (the amount of power generation and cost).
The area of the roof of the house is greatly related to this though it is an amount of power generation first of all.
For instance, there is a possibility where the amount of power generation is insufficient when the thing with so not good power generation efficiency is chosen for the environment that cannot set up a roof narrow, too big solar panel.
Then, the advantage of the photovoltaic generation is ruined.
If it is so, we will recommend buying it after it confirms how much the amount of power generation for each unit area is first of all for not being.
It only has not to be cheap for cost.
Be to choose “Commodity with a good cost performance” can firmly secure the amount of power generation on the cheap that it is important.
“HIT solar battery” etc. that seem to be expensive seemingly are actually a considerably excellent solar panels in the cost performance.
After living conditions are stabilized the important one, cost is suppressed.
Electricity is a thing always used in daily life.
Therefore, put securing the amount that it not only curbs costs but also there is no obstacle in life on the mind and choose.
Share of solar panel
Let’s verify which sells most in these commodities though they are quite a lot of kinds of solar panels that are.
It was at the 1950′s that the solar panel was commercialized for the first time.
It has disappeared from the market with surprising swiftness at that time though only “Single-crystal silicon type solar battery” exists, and this sold naturally.
Afterwards, attention begins to gather in the photovoltaic generation again when becoming the 1980′s.
A new method like the polysilicon type and the thin film silicon type, etc. was born, too and it became a market considerably near the sales form in recent years.
The most popular solar panel was “Single-crystal silicon type solar battery. ” in the 1990′s.
Originally, it seems to have extended the share since each manufacturer made efforts from could do nothing but type this by the photovoltaic generation most.
The solar battery of the CIS system was considerably extended while “Polysilicon type” and “Thin film silicon type” also gradually extended the share on the other hand, and the solar battery of the silicon system extended it considerably, and the share that followed the single-crystal silicon was acquired.
The polysilicon type of a low-priced route obtains a high share than the single-crystal silicon type with an expensive cost when entering the 2000′s.
The thin film silicon type and the HIT solar battery in addition to this two greatly extended the share, and the state for the silicon system to account for 90% of the whole continued.
And, the solar panel such as “Compound system solar battery” that do not use silicon gradually extends the share after 2005, and non-silicon system is popular in recent years.
It will be able to be said that the spread to the ordinary family shows the expansion in the 2000′s, and it becomes a low-cost route as the entire flow.
Solar battery in the future
The representative of the solar panel that doesn’t use silicon is a compound system solar battery , for example, the CIS system.
However, the solar battery of some non-silicon systems exists also excluding this.
It has not arrived at practical use yet there might not be disadvantage even if the possibility to be going to be sold as a commodity in the future is taken in advance enough because it is a certain technology and known though it is a research step.
There is the one “Coloring matter sensitization type solar battery”, “Organic thin film type solar battery”, and “Quantum dot type solar battery”, etc. in non-silicon system solar battery to which the research is advanced now.
The coloring matter sensitization type solar battery is a solar battery using the characteristic of the solar panel.
The plan of doing the photovoltaic generation by using “Coloring matter” with a similar trait to it is developed now though the power generating system of the solar panel is absorbed light, and exists in the place where the electron is discharged.
It is considerably an operative technology in the point of decrease of the cost because there is an advantage that the cost of the manufacturing process can be considerably cut.
The organic thin film type solar battery is a solar battery that used “Electroconductive polymer” and “Fullerene”, etc. that are called an organic semiconductor.
The expectation is had from flexible very high and light by the development of a solar battery that applies more and is high.
However, practical use seems to be quite difficult because there are a lot of problems of the power generation efficiency etc. at the present stage.
The quantum dot type solar battery is a solar battery using a minute semiconductor, and the most theoretical power generation efficiency is paid to attention as a high method.
More electricity will be able to be invented from sunlight if it actually puts it to practical use.
Compound system solar battery
The load rests upon the solar panel of the silicon system by all means on the cost side.
Why even the ordinary family thinks the amount for room for improvement to exist still so that [mo] power generation efficiency is sacrificed in the concept of reached commodity though the solar panel of the thin film silicon type was born by directionality of making up for the fault.
It is a solar battery that doesn’t use silicon that is called, being shown as directionality of in such and one is “Compound system solar battery”.
In a compound system solar battery, it boasts of eminence that “CIS system solar battery” that uses copper, the selenium, and indium, etc. is the highest, and there is the one that “GaAs monocrystalline” and “Cd compound thin film”, etc. were used besides this, too.
These solar batteries are technologies of the start of the research in recent years comparatively, and just starts of practical use.
Therefore, room for the development in the future in addition has been left for a multi amount.
Especially, a big advantage is thinner than the solar battery of not only the cost side but also the silicon system, and enumerated the point of lightness.
There is no weight of the solar panel because there is not a house of unexpectedly caught to weight limits due to the real and substantive problem either.
There is no difference in putting a heavy thing on the roof even if not caught to such a limitation, and the load rests upon the house in no small way.
Therefore, it has not exceeded it lightly.
Moreover, attention has gathered from the viewpoint like energy conservation and the saving resource, etc. as a technology that development can be expected.
It is likely to become an effective route in the photovoltaic generation’s being generalize directionality of solar panel that doesn’t use silicon in the future.
