What the panels' technology / manufacturer?

SolarWorld, 175 watt, polycrystalline. I don't recall any model number (paper work is filed away somewhere.) ISTR mine were made in Germany. I think at the time my system was installed, there where some 225 watt panels available, but the 175 ones were a better price point per watt.

[edit - added technology]

  • The SolarWorld company is no more :(

    Which means your experience is irreplicable, other companies' solar panels may be crap.
