I now know the reason for the panels to hardly stand out at all on the roof - they were installed "flat" on the roof - giving them an elevation of about 12 degrees - they should be at 26 degrees for optimum grid-connect performance across the year given our latitude (36 south) (see here for more details). So the installers will be back on Friday to fix this. I could have a nice rant about how it shouldn't be up to us to find out the panels were not at the optimal angle, and that this surely was the most important part of the whole process....but I'm going to take a deep breath and let it go. OK so maybe a deep breath and a glass or 2 of wine and THEN let it go :-)
However, in spite of the less than optimal angle, today, on their first full day, our system produced 12 kwh. Given the installer estimated 10 for this time of year I'm quite chuffed by that!

Ta-da!
They are hardly noticeable on the roof from the front of the house, but I'm loving watching the meter spin backwards. The great thing is that because we have an old dial style meter, they were able to plug the panels in straight away and we're already feeding power into the grid, and reducing what we will have to pay next bill.
Today in the 4 hours since installation they have generated over 6 kw, and our meter has rolled back about 4kw. Loving it!
