Claim Text:
1. A rail system for a photovoltaic array, the rail system comprising: a first vehicle comprising at least a first wheel, continuous track, or caterpillar tread and a second wheel, continuous track, or caterpillar tread; and a plurality of modular rails each along a first direction, each of the modular rails including a unitary, elongated piece of extruded concrete disposed on graded ground of an installation site, the graded ground having an uneven surface substantially filled by the unitary, elongated piece of extruded concrete; wherein each of the unitary, elongated pieces of extruded concrete is spaced apart from each other of the unitary, elongated pieces of extruded concrete by a respective gap; wherein each of the unitary, elongated pieces of extruded concrete includes a first substantially flat vehicle support surface along the first direction, the first substantially flat vehicle support surface being substantially parallel to the ground and unobstructedly receiving the first wheel, continuous track, or caterpillar tread of the first vehicle; wherein each of the unitary, elongated pieces of extruded concrete further includes a second substantially flat vehicle support surface along the first direction, the second substantially flat vehicle support surface being substantially parallel to the ground and unobstructedly receiving the second wheel, continuous track, or caterpillar tread of the first vehicle; wherein each of the unitary, elongated pieces of extruded concrete further includes a first raised surface along the first direction, disposed between the first vehicle support surface and the second vehicle support surface and raised relative to the first vehicle support surface and the second vehicle support surface; wherein each of the unitary, elongated pieces of extruded concrete further includes a second raised surface along the first direction, disposed between the first vehicle support surface and the second vehicle support surface and raised relative to the first vehicle support surface and the second vehicle support surface; wherein each of the unitary, elongated pieces of extruded concrete further includes a first substantially flat plenum disposed between the first raised surface and the second raised surface, the first raised surface and the second raised surface being raised relative to the first substantially flat plenum; wherein each of the unitary, elongated pieces of extruded concrete further includes a second substantially flat plenum disposed between the first raised surface and the second raised surface, the first raised surface and the second raised surface being raised relative to the second substantially flat plenum; and wherein each of the unitary, elongated pieces of extruded concrete further includes a third raised surface raised relative to the first vehicle support surface, the second vehicle support surface, the first substantially flat plenum, and the second substantially flat plenum, the third raised surface being disposed between the first substantially flat plenum and the second substantially flat plenum; wherein:
