Just to give figures for a rather different distribution, since Germany's photovoltaics registry is on-line and I put that in a spreadsheet too recently; for Germany's record year of 2009 (when large green-field and industrial rooftop plants had a greater part than in previous years):

1-51 MW: 638 MW
0.1-1 MW: 635 MW
40-100 kW: 600 MW
20-40 kW: 914 MW
10-20 kW: 548 MW
0-10 kW: 472 MW
