KGO-AM switches to solar power

KGO-AM 810 on Thursday became the first major broadcast station in California to use solar power for its transmitter. Here's the transmitter building with solar panels as seen from the eastern approach to the Dumbarton Bridge. On the Ronn Owens show, House Speaker Nancy Pelosi flipped the switch that turned on the studio's new solar panels.

KGO-AM Transmitter Engineer Art Lebermann notes in his blog on the solar project that the concentrated photovoltaic panels "are mounted on dual-axis trackers that allow the panels -- like much of the plant world -- to follow the sun as it moves across the sky during the day. This means that unlike traditional fixed panels, the SolFocus panels are positioned for the best possible energy generation during all daylight hours."
