Danville Solar is a 2.62 MW-DC ballasted solar field located in Danville, Illinois. It is located atop of an EPA superfund site. Due to the classified nature of the system, no conduit or wire could be run underground. Gaylor was also responsible for the interconnection to the grid using our Utility division.
The general contractor (Inovateus) was awarded this project without a set of owner approved drawings. As a result of this, Gaylor helped to design a code-compliant array that would minimize cost impact. We ran conduit above ground using pre-cast parking bumpers with strut mounted on top of them. The next problem incurred was that the engineer of record couldn’t come up with a way to secure the conduits to the rack while still allowing movement for the expansion and contractions of the conduits due to the weather conditions throughout the year. Expansion joints were implemented every 100’ and Stainless minis had an extra nut put in them so that it could be torqued down and rigidly support the conduit but still allow the material to expand and contract without incident.
