OFF-GRID SOLAR-POWERED WATER WELL IMPROVEMENT

This project was implemented to improve the pumping rate, and total yield, of an off-grid, solar-powered water well. The improvements included the design and installation of a tank farm, secondary solar array, and solar pumping inverter. The daily pumping yield was increased by ~50% as a result.

Pacific Coast Engineering performed a system design and ROI analysis, followed by a detailed Bill of Materials (BOM) and contractor selection. Our project management services then coordinated the scheduling, and scope of work, of the water well, solar and general contractors involved.
