Sun Gold Power 30w Polycrystalline Solar Panel Module Kit - China

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.
