I used Luminalt [1] and they did a great job throughout the whole process. The installation job was at the highest degree of quality and professionalism that I've experienced.

Though it hasn't been inspected or turned on yet (happens later this week), so I'll see how close their projections were to reality over the coming months as the juice is generated. I did my own projections independently and found that their projections seemed to be on the conservative side, so I'm optimistic.
