About this file
This document contains a voltage drop calculation for a photovoltaic system project and the related federal contract opportunity solicitation. The voltage drop calculation specifies wire sizes and lengths for three PV circuits, with circuit one requiring 3/0 aluminum wire over 151 feet, circuit two requiring 1/0 aluminum wire over 220 feet, and circuit three requiring 1/0 aluminum wire over 574 feet. The related solicitation is for renewable energy systems in the U.S. Virgin Islands and seeks design and installation services. Offerors must submit proposals to the Department of the Army Michigan Army National Guard by September 30, 2020. The solicitation was amended to include additional design specifications and points of contact for site visits on St. Croix.

* - YOU CAN ENTER EITHER AMPS OR VA. IF YOU HAVE VALUES FOR BOTH, THE PROGRAM WILL USE THE (AMPS) VALUE.
NOTE: FOR PARALLEL SETS OF CONDUCTORS, YOU MUST DIVIDE THE TOTAL AMPERAGE BY THE NUMBER OF SETS OF
CONDUCTORS TO GET THE (AMPS) VALUE TO USE IN THE TABLE ABOVE.
