The SUN offers much more energy than what we could consume!
History of Photovoltaics
Photovoltaics (PV) or solar cells as they are often referred to, are semiconductor devices that convert sunlight into direct current (DC) electricity. Groups of PV cells are electrically configured into modules and arrays, which can be used to charge batteries, operate motors, and to power any number of electrical loads. With the appropriate power conversion equipment, PV systems can produce alternating current (AC) compatible with any conventional appliances, and operate in parallel with and interconnected to the utility grid.
Solar panels used to produce electricity
The solar panels used to produce electricity, are really
interesting, because generating electricity free. On the basis of this
process is photovoltaic cell. In short, in contact with the sun, it
produces electricity. Fotons of sunlight (such small particles produced
especially by the Stars, moving with light speed) "bombe" atoms in the
material which is made photovoltaic cell. Under this, they undergo
transformation releasing electrons (thus forming electricity).
Photovoltaic cells are grouped into matrices, which in turn make up the solar panels.
The advantages and disadvantages of solar panels
The advantages of using these systems are obvious: renewable energy
and free, which can be used to supply permanent dwelling citizens. It
is true that the cost of an WATT through solar panels is 6-7 times
higher than the cost of producing its thermal, but the investment
depreciated over time. In addition, do not forget: solar panels are
organic. And how natural resources are already in danger of exhaustion
would be little time to think about our future and our children right
now. May be clearly said that the purchase price of the entire equipment
is still high (but the price is constantly declining, and in addition
it is paid only once in principle, following the much to pay in a
number of years a maintenance fee installations and equipment are
depreciated in a number of years, even after they become profitable,
while cleaner technologies of the future come down, they might drop
their price even if now would be produced in industrial quantities much
higher, produced by modern technology (resulting from advanced
scientific research, which must attend mandatory collective
multidisciplinary), for these reasons the production and their use
should be compulsory controlled by governments through agencies and
government departments of energy, environment, creation of new
technologies, industrial and scientific, all governments are called
upon to subsidized the purchase price of equipment
at least for a period of 20-40 years, that is, as long as the equipment
is still in an experimental stage and technology manufacturing cost
which is reflected even in their purchase price.
The efficiency of solar panel very much depends on the angle under
which falls on the solar radius, which implies the need for mounting
such a system of energy production by specialists. To cover energy
needs of the whole case will be a need for solar panels many tens of
square meters because the equipment needed to cover the entire home and
family concerned and the old contracts for the supply of electricity to
end total in this way is truly unloaded the national energeticaly
system, is an economy of electricity produced classic, and an decrease
of indirect losses of transport networks. Because yes, it is possible
that a dwelling to work exclusively with solar energy in ideal
conditions.
The production of electricity with solar panels are reliable, can
hold up to 25 years. Their performances have raised increasingly in
recent years, and the price of assembly and made decreased. It is
estimated that the price of electricity generation by panels with
photovoltaic cells will equal that of polluting energy (produced by
thermal power). To top solar panels are ideal for the supply of
electricity to isolated housing, the research points or satellites
(they used for the first time this type of energy).
Solar panels with tubes vidate have a higher efficiency, they
absorbed very well and diffuse radiation, solar radiation that is
existing and long cloudy. Heating transported by panels
is a kind of antifreeze generally resistant to -28 degrees C. So do not
freeze in winter (but have lower performance due time sunny relatively
small, a few hours/days). Low temperature outside influence only to a
small extent the operation of the system, respectively, if the loss of
heat pipe routes by moving the heat are isolated properly (have shown
that fotons always have the speed of light and works as if the sky is
not Cloudy, but plant yield is lower because of fewer hours of light, a
fact that the equipment should be over, so as to generate enough energy
during the winter, following the excess of long sunny days of summer
are accumulated, consumed additional transmitted through a network,
used for various other tasks, such as public lighting additional
summer, or simply dissipated (something undesirable).
