production becomes less energy-intensive currently: The running time it
takes to compensate the production energy needed further sinks. In
accordance with an investigation of ETH Zurich / PSI Villingen in 2000
production energy of a PV module is compensated within less than six
operational years by its solar electricity generation. In the whole-
ecological analysis solar electricity proved to be 3 times more
ecological than the normal Swiss electricity mix (with a high number of
hydroelectric power plants), in comparison to the European electricity
mix it is better even more significantly. The production process of
polycrystalline cells is clearly less energy-intensive than it is for
mono-crystalline cells and it is also cheap solar panels, because e.g.
lower temperatures are needed. finally, also the slower degradation. The
performance loss runs clearly slow as compared to mono-crystalline
cells. Hence, about the years calculated, polycrystalline cells offer
better yields. Also the performance temperature coefficient is better
with polycrystalline cells. The cells heat up more slowly than mono-
crystalline. Because every warming leads, however, to lower performance,
polycrystalline modules as a rule reach better yields in Middle- and South-
Europe than mono-crystalline ones. On account of these facts the
ancillary industry has concentrated increasingly upon the manufacture of
polycrystalline cells. This means that today there is a clearly bigger
offer for poly- than for mono-crystalline cells.
