Our Barn Roof Gets an 18-kW Solar Array

We’re installing 72 photovoltaic modules on the standing-seam roof of our Vermont barn

Posted on Jun 13 2013 by Alex Wilson

When we started planning the rebuild of our house and the rest of the farm in West Dummerston, Vermont, my wife and I knew that we wanted to produce all of our energy on-site. That meant a solar-electric or photovoltaic(PV) Generation of electricity directly from sunlight. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow. (PVPhotovoltaics. Generation of electricity directly from sunlight. A photovoltaic (PV) cell has no moving parts; electrons are energized by sunlight and result in current flow.) system that would generate as much electricity as the house and barn are consuming — net-zero energyProducing as much energy on an annual basis as one consumes on site, usually with renewable energy sources such as photovoltaics or small-scale wind turbines..

Staying Cool with a Metal Roof

Metal roofs are durable and recyclable — but do they really save energy?

Posted on May 21 2012 by Scott Gibson

David Martin is intrigued with the idea of replacing his existing roof with a standing-seam metal roof. It should last longer than the alternatives, he says, and it would be compatible with photovoltaic(PV) Generation of electricity directly from sunlight. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow. panels should he decide to add them in the future.

So what’s the issue?

David Martin is troubled by some of the advertising claims he’s seen about metal roofing, specifically a statement from the Metal Roofing Alliance that a “cool metal roof can save 25% in energy costs compared to a dark grey asphalt shingle.”
