FOR SOLAR PANELS: make it clear

a bit 'of clarity about the type of photovoltaic modules:


cells of the monocrystalline silicon modules consist of a single crystal silicon. In pure silicon atoms are perfectly aligned thereby guaranteeing the highest conductivity. The increased purity of the material ensures a higher return (equal to 15%). Photovoltaic cells are presented in color and very dark blue uniform, usually, have an octagonal shape with a thickness of about 0.2 to 0.3 mm. The monocrystalline silicon photovoltaic modules are ideal for those who have access to a limited area of \u200b\u200binstallation

polycrystalline silicon:
cells of polycrystalline silicon modules (also called multicrystalline) consist of a set more silicon crystals, this lower purity is the cause of lower returns, which is between 11% and 14% against 15% obtained by using silicon cells monocristallino.Esse they remain aggregated together (polycrystalline structure ) and have different shapes and orientations. They are characterized by blue intense iridescent. Thanks to new manufacturing technologies and high investment in research and development, production costs have been lowered further and managed to achieve good levels of efficiency

THIN FILM
thin film modules are made a thin layer of crystalline silicon (1 - 2 microns) applied on a glass plate by cathodic deposition. In this case we are talking about cells in that, thanks to this technology, large areas can be covered continuously. Advantages of thin film: low impact, return period less than ideal conditions of low irradiance and high temperatures.
What is a CIS solar cell?
The acronym stands for Copper CIS (= copper), Indium (= India), Selenium (Selenium =).
It is therefore not using photovoltaic panels silicon as the sensitive material
sunlight, but the "Copper and copper indium diselenide (CuInSe2)
What are the advantages of a CIS panel?
There are practical advantages of considerable importance:
Lower cost

The lower cost of producing a panel
CIS is due to the use of materials less
expensive than silicon, is a technology
more economic production, and this generates
advantage of a lower cost product
finished.
The material is deposited in accordance with the
technology Thin Film (Thin Film = ), ie a
layer a few microns of material
photovoltaic against the 250-350 microns of
crystalline silicon cells
Best yield partial lighting.
In the case of crystalline silicon solar radiation is the best among the panels in production today
industrial, materials with higher yield photovoltaic specific (ie the material that
produces the greatest number of watts x m2
. (However, when irradiation is not optimal,
eg. in case of partial shading ,
a crystalline silicon panel has a sharp
drop in production in as little as
efficiency of a cell affects all
cells connected to it
The "amorphous" in part addresses this aspect, but has much lower efficiency of silicon
lens ( 7-8% against 14-18% for crystalline silicon panels) and therefore requires a
surface panels is much higher (about twice)
CIS photovoltaic modules last
generation have a rather 'efficiency
may reach 12-13%, comparable to
that of polycrystalline silicon (14%), and
suffer less loss of productivity in
case of partial shading: in the last
analysis therefore gives a greater
average amount of energy produced, with the same
power.
Also, thanks to the particular configuration
material, technology Thin Film
allows for panels CIS flexible.
As for its performance,
the decrease in production over the years a
CIS module is similar to to form a
crystalline, ie after 20 years produces 80%
of rated power. There are negative aspects?
One thing to consider when choosing a
CIS module is the biggest size
panel compared to a silicon modules
crystal with the same power.

amorphous silicon is a good product when the display panel is not in a perfectly sunny, as these panels have made a discreet also working in areas with frequent problems of shadow. This is not ideal for campers because the output voltage is too high for normal batteries.

PHOTOVOLTAIC MODULES FOR CAMP, CAMPER AND BOAT ®

Enecom produces flexible modules different sizes and power using crystalline silicon cells with high efficiency.

The technical panel Enecom make this product particularly suitable for the marine industry and the camperistico that require bending for the use of materials, shatterproof, durable, waterproof and lightweight.
The unique construction of this product makes it suitable for direct installation on the deck of the boats and the roofs of mobile homes, without fear of damage caused by vibration, high temperatures or by contact with seawater. The installation can be completed either by gluing or by using an innovative method, called dual lock, which allows the panel to be attached to the surface through a system similar to Velcro.
Enecom panels can be curved arrow with a maximum of 30% of their length and are installed on a hard surface, can be walked on.
Enecom forms of the junction box and connecting cables are resistant to UV and salt water. The special plastic material that incorporates photovoltaic cells can be transparent, white or black.
are also available, on request, modules with different power and voltage than standard.
