About this file
This document contains design drawings and technical specifications for a solar-powered submersible pump system to be installed at a watering facility in North Dakota. The drawings provide details on the solar panel array, mounting posts, pump, controller, and other components required for the system. Key specifications include panel size, power output, voltage, and wiring configuration, as well as post diameter, embedment depth, and concrete volume for different array sizes. The installation must meet North Dakota NRCS Specification 614 - Watering Facility.
The related state and local contract opportunity is an Invitation for Bid (IFB) for the reclamation of Abandoned Mine Land (AML) sites in Mercer County, North Dakota. The Dakota Collieries Mine Site, located 3 miles southeast of Zap, contains an abandoned underground lignite coal mine and is the focus of this project. The IFB is issued by the North Dakota government for this AML reclamation work.

AutoCAD SHX Text NOTES: 1. PV panels are to shown to be tested and listed by PV panels are to shown to be tested and listed by Underwriters Laboratories (UL) to meet UL 1703 or tested and certified to withstand the impast of a 25-mm (1-inch) diameter hail at a minimum velocity of 23-m/s (51-mph) without major visual defects by another nationally recognized testing lab in accordance with IEC 61215 or IEC 61646. The panels are to also be certified to withstand winds of 130-km/hr (81-mph) or greater and an ice loading of 25-mm (1-inch) thick minimum over all exposed surfaces. 2. Installation of the storage tank shall meet North Installation of the storage tank shall meet North Dakota NRCS Specification 614 - Watering Facility. 3. Minimum post diameter, post hole diameter and post Minimum post diameter, post hole diameter and post depth values in the Mounting Post Section Table have been designed for a wind speed of 95 mph and a 1 inch thick ice load. Soil properties for the foundation design were presumed to have an allowable bearing pressure of 1,500psf and a lateral pressure per unit depth of 100psf/ft and is representative of all soil types except for organics. For a site whose conditions do exceed these design parameters, the required mounting post size and embedment depth will need to be determined by a qualified engineer. 4. The concrete backfill is to be properly batched above The concrete backfill is to be properly batched above ground prior to placement in the post hole. It is not acceptable to place dry ready mix concrete in the post hole and then fill the hole with water. 5. Care should be taken that all connections associated Care should be taken that all connections associated with the solar power system are made of similar materials to avoid the potential for corrosion. 6. The PV panel mount and all electrical components The PV panel mount and all electrical components shall be properly grounded to provide lightning protection. Lightning rods are recommended for systems installed on high terrain if lightning is a known problem.
