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

    price: contact company for price

    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.
