Sun Gold Power 50w Polycrystalline Solar Panel Module Kit - China

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.
