Photovoltaic Panels' disposing


How long do solar panels? How much is the disposal of the panels?
What kind of photovoltaic systems exist and how long they last?

There are two major types of systems: stand-alone (with storage tank or stand alone, ie not connected to the network) and the network (or grid connected).

The autonomous systems use the energy produced by sun exposure during the day to charge a battery and release, then, the energy stored during the night or when the sun is covered, for food items of small and medium-sized (emergency tools , streetlights, repeaters, etc..) that do not naturally have a great assorvimento .... in case questoo fact necessitates the presence of auxiliary batteries intervening where the energy produced by the plant was no longer enough we ... For example, a beacon of a harbor difficult to think may stop working!

The grid-connected systems are normally used to supply power to an electricity grid already 'powered by conventional generators and surrender to the Distributing surplus, using a special meter that records the flows of entry and exit. Unique feature of these systems is the inverter, which converts direct current into alternating current. There is also a special counter that "counts" the energy produced and consumed, and that instead the grid.


Solar modules have an expected life ranging from 50 to 100 years or so, even if it is PROBABLE THAT AFTER THE FIRST 20/25 YEARS OF THE OPERATION OF YOUR CELLS PANELS AND DROPS IN TERMS OF YIELD IN A RATHER SUDDEN ... but with This does not mean that they stop working!

The modules to access grants for energy must be guaranteed by the manufacturer for at least 20 years, so we can safely say that a photovoltaic system has a guaranteed life of at least 20 years ... but AFTER?


In reality, the problem is rather bogus .... first of all the silicon, which is the primary part of the panels, it is virtually "sand" disposed of, as to the forms of the computer or printed circuit boards. Material is not toxic, it is not against material nature. The panel is covered by a sheet of tempered glass, which is to be disposed like the crystal, and is finished by metal profiles. There is then a layer of EVA (ethyl vinyl acetate) which is to be disposed as it does with waterproof tablecloths. Cables and junction boxes are normally used in construction. Without consideration that these considerations do relying on what is today's technology ... maybe in 15 or 20 years and more, we have refined the technology of recovery and Recycled materials so as not to doversene not even worry ..... . maybe your photovoltaic panel become part of the frame of your future motorcycle!

Photovoltaic systems do not require complex or expensive disposal procedures. TODAY MANY ASSOCIATIONS are springing WITHDRAW FREE SOLAR PANELS at the end of their useful life (25 years) to be able to then launder.

They are classified under the following EWC codes:
codes that identify materials elettrci.
There is a code that identifies only the PV module
A different needs to be done in the case of panels containing cadmium telluride is a toxic material and in fact many of the leading manufacturers of photovoltaic panels is abandoning this type of product to do just that in silicon.


The new legislation relating to the fourth Conto Energia de facto obliges manufacturers of photovoltaic panels to join a consortium for the disposal of solar panels by 30 June 2012.

This is also required by the legislation of the European Waste Electrical and Electronic Equipment, the WEEE that has so classified photovoltaic panels: for those who have access to incentives installs panels must be used in conformity with these guidelines and then manufactured by companies that ensure the recycling and disposal.

Hence that is already being born the business linked to the next recycling of the panels because, as seen above, by the panels discontinued are obtained, in addition to glass and aluminum, even indium, gallium, selenide, precious metals become because of the enormous usage.
