Off-Grid Water Solutions: Installing an RPS Solar Well Pump System

Welcome back to Base Camp WNC! Today, we're tackling an exciting off-grid project: installing an RPS solar well pump system designed to provide reliable water access for livestock and potential household use.

Overview of the Project
The landowner has chosen an RPS solar pump to draw water from a deep well, filling a 2,500 or 3,000-gallon storage tank. This tank is strategically placed to gravity-feed water downhill to livestock pastures and possibly supply future household needs.

Solar Power Setup
The system is driven by 1,200 watts of solar energy using RPS solar panels, complete with racking and adjustable angle brackets for optimal seasonal performance. However, additional components like piping and well wiring were sourced separately. The solar panels are mounted on sturdy 4-inch galvanized pipes, buried 5 feet into the ground for stability.

Electrical and Grounding System
The system includes two ground rods for electrical safety. A wire from the solar panels connects to three additional ground rods, spaced 6 feet apart, ensuring compliance with local codes. The RPS Universal Pump Drive powers the pump, positioned at a depth of 300 feet in a 500-foot well. One notable feature of this setup is its ability to switch power sources, running directly off a generator if needed.

Pump Capacity and Flow Control
The RPS pump delivers up to 18 gallons per minute, adjustable down to 10 gallons per minute. Multiple valves control water flow: one for the well, one for the pastures, another reserved for future household use, and an overflow valve that directs excess water to a pond. The system also features an electric float switch for automatic on/off functionality.

Tank and Valve Protection
The water storage tank sits on a base made from rough-cut treated lumber, buried a couple of feet underground to prevent freezing. Flexible hoses connect the tank to various outlets, allowing for expansion and contraction without damaging the pipes. A modified 55-gallon drum serves as a protective cover for the valves, ensuring stability and shielding the system from potential damage.

The tank area is backfilled with gravel, following recommendations from the manufacturer's representative, to accommodate any movement from tank expansion.

Overflow and Expansion Features
The overflow system directs excess water to a pond, providing a secondary source of water for local wildlife. The landowner has planned for future upgrades, including the addition of more solar panels or a battery backup for nighttime operation.

Assembling the RPS System
The landowner assembled the entire RPS variable speed pump system using detailed instructions provided by the manufacturer. Although technical support response times may vary, the project is manageable for a dedicated homeowner willing to put in the effort. Future plans include installing a deep well pump for grid power once the house is built.
