Sungold Power 30w Polycrystalline Solar Panel Module Kit - China

we have polycrystalline module , which is made from a block of silicon

that has multiple crystals.

These panels are square in shape, and may

have a surface that looks somewhat like a mosaic.

polycrystalline

modules offer the following advantages: Modern cell 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.
