  • Sungold Power 30w Polycrystalline Solar Panel Module Kit - China

    price: contact company for price

    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.
