the components of the Solar Photovoltaic

The main element of the system is the photovoltaic module , that exposed to the sun produces energy. The module consists of solar cells based on silicon, suitably treated to produce energy.

The monocrystalline is made from an ingot whose atoms are arranged to form a single crystal.

The polysilicon lotus has many crystals joined together, while in amorphous silicon atoms are arranged disorderly.

The various types of silicon are different in appearance and efficiency, the latest is the thin film, which delivers high performance, flexibility and competitive pricing.

The silicon cells are protected by a glass with special strength and transparency.

The power is expressed in the form Wp Watt peak, whose value indicates the amount of energy produced under standard conditions.

L ' inverter is an electronic device, adjusting the energy produced by the panels to the electrical and building the network, transforming direct current into alternating current.

The photovoltaic panels are fixed to a support structure that tilts the modules with the optimal angle of 30 °. The structures can be galvanized steel or aluminum. Are there facilities "trackers" or "tracker", which move during the day just chasing the sun.

last part of ' photovoltaic an electronic control device connected to the inverter, with which it is possible monitor the production of energy through a PC.

The opinion of leading experts in the renewable energy is unanimous about the possibilities of photovoltaics as evidenced, in 2009, as an energy resource that will be used not only in residential but on an industrial scale. Thus, a farmer can install a photovoltaic system on the ground?

Certainly, since the decree of Energy Bill expected between the types of plants you can enjoy the incentives is the "system is not integrated." The ground-mounted panels fall into this category, since they are not coplanar to the surface. The photovoltaic panels must be fixed to a structure that will be anchored to the ground.

The preparation of the fund may be more or less expensive according to the issues that may present a target site. E 'to rule out rather expensive to build a concrete platform and avoid the growth of grasses and shrubs and their maintenance, but it is an impressive work and expensive.

more viable alternative is to build the footings buried where the structure will be fixed and the soil will be compacted.

For the installation of a plant to the ground you need 20 square meters per kWp to avoid that the panels are ombreggino each other if they are too close.

The new decree stipulates that the Energy Bill photovoltaic installed on the ground can be achieved even in farming areas, without need for the change of use of the site.

Agriculture Development Prospects for photovoltaics Photovoltaics Renewable

the analysis of the GSE (Electrical Services Manager) on the prospects for development of renewable energy, shows a growth scenario with interesting opportunities. In Italy the Energy Bill will drive and support for the next year and will record significant growth rates, especially if the state will try to simplify administrative procedures and licensing.

The domestic industry will seize the opportunities arising from increased demand for renewable energy , turning the experience already gained in other sectors, such as mechanical, electronic, electro ... to be able to accomplish here in Italy the plant components, without going abroad only. The application is set to rise and Italy should not miss this opportunity.

E 'therefore act in a competitive and technological challenge with international producers, the Italian companies must show their ability to retain the value of investments in Italy and to promote maximum employment nationally.

The experience of Germany, the European leader in the industry of renewable energy, shows how you can be successful by investing in developing technologies, creating opportunities and jobs, which are still growing!

The global investment in renewable energy more than doubled in the period 2005-2007, to about $ 160 billion in 2007. The breakdown of investments by sector, highlighting the success of renewable technologies for electricity generation, particularly solar energy has increased by more than twelve times the value propprio throughout the three years.

The range of cells and photovoltaic modules is concentrated in the hands of few producers today with the first five (Sharp, Q-Cells, Kyocera, Suntech and Sanyo) that hold over 50% of world market share.

Almost all major manufacturers of solar energy planned to expand production to thin film, which offers great performance and flexibility for building integration.

In Italy there has been an acceleration of growth in photovoltaic solar installations since 2007, due especially to the activation of the new Energy Bill introduced by the DM 02/19/2007.

GSE estimates that the total installed capacity will reach 900 MW in 2009, approximately 70,000 new photovoltaic made within the year. Based on these trends of growth in 2010 will be achieved in Italy about 1,500 MW of power.

for the condo, is it possible? Architectural integration of the photovoltaic

also a building has the ability to install a photovoltaic . You can follow two different paths: either a single tenant decides to build its own equipment for the common parts, or you shall unanimously all the condominiums. In both cases you need permission from the Assembly.

It 'important to note that, in addition to saving on electricity bills, the new system offers considerable opportunities gain. In fact, a planting of about 50KW produces an average gain of 3000/3500 € per month: once this budget passed, the depreciation period of the initial expense, can be used to further reduce operating costs divided between the condominium or condominiums.

To install a photovoltaic condominium there must the space required for installation and exposure sunny. The flat roof in a building of great height is ideal because it avoids the considerable expense to secure the roof to install.

The size of a photovoltaic system condominium is usually of 20 kWh, this is sufficient to meet the energy needs of households shared about 20/60 family.

however, checked the available budget, the size of the plane and consumption, one can determine the right size plant.

However, as an example: an installation of 20 kWh, 160 square meters surface, can produce an average of 28,000 kWh per year, which in 20 years make about € 320,000 incentive from the Energy Account.

To access the energy bill is necessary, within sixty days after the entry into operation, the network operator to send the following documents:

Documentation of compliance of the CEI

Technical plant

Certification Test

Declaration in lieu of notarized affidavit

PARTIAL TOTAL

For partial architectural integration means that photovoltaic modules not going to replace the materials of construction of a building, but will be set to the same.

Specifically, the partially integrated photovoltaic modules are installed on roofs, roofs, facades, balustrades or parapets of buildings and manufactured as flush with the surface support without the replacement of materials constituting the bearing surfaces themselves.

E 'essential that its inclusion in the photovoltaic not undermine the appearance and functionality of the building , in particular for what concerns energy efficiency.

This requires that the thickness of the panel and the supports that attach is minimized and that does not protrude from the sloping roof.

architectural integration of the photovoltaic

The GSE has published a guide on the integration of architectural photovoltaic . With this initiative, the government agency wishes to emphasize that, to get the premium for building integration, the system must have characteristics significantly different from the systems on the ground, paid with a special rate. To that end, deemed it appropriate to characterize certain types and architectural structures, as well as advice on how to integrate the modules necessary to recognize the architectural installation.

To enjoy the incentive rate of a photovoltaic system is fully integrated , it must: Replacing roofing, roofs, facades of buildings and buildings with the same inclination and architectural features of the coated surface.

be admitted to the incentive rate for the total building integration also cases in which:

A) The modules cover a portion of the roof.

B) The modules cover the total surface roof.

C) has been made of the design solutions industrialization for new building components for solar covers civil, industrial or commercial purposes.

Proper architectural integration of a photovoltaic , unable to match the ability of PV to produce electricity with the aesthetic quality of space architecture that houses it.

architecture to fully integrate the photovoltaic means being able to balance the technical and aesthetic components of photovoltaic technology on the structure of the building.

The visual characteristics of the photovoltaic module - shape, size, color, transparency possible - may become elements of characterization of the architectural space. Photovoltaics is interpreted as true and used building materials and becomes a fundamental part of the building. Replaces a conventional building material, becoming an active component of the building structure capable of contributing positively to the energy performance of buildings.
