T-cantilever solar carport on the top deck of a parking structure at dusk

Solar carports · T-cantilever

TITAN. Two rows of parking nose to nose.

The TITAN carries the array over a double row from a single central column line, so one structure shades four spaces and the drive aisles on both sides stay open. It is the most efficient geometry per square foot of canopy and the usual choice for the interior rows of a large lot.
