As the roof had to be clear for fire department access, Baker developed a cantilevered frame for double-sided solar collectors that is elevated a few feet above the rooftop. The frame’s tilted configuration actually allows the panels to collect more energy than traditional flat designs. Seen here before the panels were installed, the frame holds sixteen photovoltaic collectors and is a 3KV system—large enough to generate more energy than the house requires in a single year.
