Nik I just bought a new mono solarworld 250 and it also has a new stle frame with no feet, I believe they have switched to the new frame for all their models now. Limits options for mounting to only using top clips, not good in my opinion. I believe they are working on their own clip system, last I saw it looked a bit "German" and a liitle too fancy for my tastes. I have not compared glass surfaces between the two models, but I would suspect that they are switchign to the " cheaper reflective glass on all their new models. Cutting cost in one place and adding in another! Over all thouh a good solid module.
