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

    price: contact company for price

    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.
