What You Need to Know

Maintenance Requirements:

No maintenance has been required. Knocking snow off is fun, but optional.

Efficiency or Sustainability Improvements:

Residence uses about half the state average, annually. Efficient appliances and lighting, insulation & window retrofits, and occupant behavior all contribute.

My Motivation:

Environmental benefit, primarily. And geek-factor.


Hire a reputable installer. Get multiple quotes. Know who will actually be on your roof.

Experience with Installer:

The outfit I hired oursourced the actual installation to an electrical shop, and the people on the roof were not terribly experienced. When I removed some panels for a later roof modification, there were some installation errors discovered.
