SOLAR - WHO'S INSTALLING IT?

I was just in a conversation about solar and I was under the assumption that most roofing companies are not installing much. My friend said that a lot of contractors are sub-contracting from the big solar companies.

Are you selling and installing?

Are you the sub-contractoring?

Is sub-contractoring a real word?

I also wonder if any commercial contractors are installing or just residential.

He did a solar shingle on his shop.

I inquired at Certainteed and DOW about getting solar shingles and neither are pushing them in this area.

I take it that no-one is doing any solar? Wasn't Lefty?
