ABSTRACT

Nor green business, however, designed precisely to reduce the amount of waste that
modern society and its technologies generate, is not entirely trouble-free in relation to
waste. This problem also applies to photovoltaic. The issue of life cycle and the final
disposal of modules and materials is more or less long a major role for industry. Total
amount of photovoltaic waste in Europe is still relatively sm all and moves around 3800
tons in 2020, this number will grow to 35 000 tones. Sooner or later it will be necessary
to address this issue in Slovakia also. Most manufacturers of photovoltaic products in
Europe are in Germany where he is also the largest photovoltaic market. No wonder that
Germany will be the first European country where large volumes of photovoltaic
modules are approaching the end of its operational life and its removal and disposal is
becoming a major problem. Logic suggest that Germany will be one of the first
countries where will be developed specialized equipment for processing secondary
waste of photovoltaic technology. Slovakia in line with renewable energy sources
development strategy prefers the use of photoelectric conversion in particularly in
electricity supply of industrial parks. Since 2010 are being built a large-scale
photovoltaic power plants in various districts of Slovakia.

Factors that determine economic threshold for the use of materials are market share,
price of raw materials, and availability of raw materials during production. Photovoltaic
modules contain various highly valuable materials that can be in many cases
economically exploited. Lack of materials can be a serious problem. Recycling is
therefore one of the options how to limit the supply of necessary materials.
