πŸ“Š Energy and Water Budget – Tri-Source Water Node

This page documents the daily energy consumption and water output targets for the integrated Tri-Source Water Node system, based on field-validated benchmarks and real-world solar availability in arid and coastal regions.

β˜€οΈ Solar Input Assumptions

Parameter Value
Solar Array Size 5 kW (PV + Thermal)
Peak Sun Hours 5.5–6.5 hrs/day
Raw Solar Output 25–32.5 kWh/day
Net Usable Energy ~22–27.6 kWh/day (85% efficiency)

πŸ’§ Daily Water Production Targets

Source Target Volume (L/day) Reliability
Atmospheric Water (AWH) 2–5 L/day Weather dependent
Greywater Treatment (MSSC) 40 L/day High
Desalinated Water (SPMD) 20 L/day Very High
Total Output 62–65 L/day Good

⚑ Energy Budget Summary

Subsystem Energy Use (kWh/day)
Atmospheric Water Gen 2.0 (sorption-based)
MSSC Biotreatment 2.0
Desalination (RO/SPMD) 0.04
Auxiliaries (pumps, controls, UV) 3.0
Total Daily Use ~7.0 kWh/day
Solar Headroom ~15–20 kWh/day

Note: Up to 5Γ— energy surplus available during peak sun for buffering, backup, or expanded output.

⏱️ Suggested Daily Operation Cycle

Time Block Task Energy Priority
6–10 AM Desalination (low-load startup) βœ… Baseline
10 AM–2 PM AWG operation (solar peak) βœ… Energy-intensive
2–6 PM MSSC biotreatment + circulation βœ… Intermittent
6–10 PM Final polishing + monitoring ⚑ Battery-supported
Overnight Standby mode (minimal load) ⚑ Battery

πŸ”‹ Storage Guidelines

  • Battery:

    • Size: 15–20 kWh usable (LiFePOβ‚„)
    • Function: Overnight load, cloudy day buffer

  • Thermal Storage:

    • Size: 100–200 L insulated tank
    • Function: Heat buffering for AWG and SPMD

  • Water Tanks:

    • Potable: 100–200 L
    • Non-potable: 200–300 L
    • Brine: 50–100 L with mineral recovery options

βœ… Summary

  • Tri-Source Node can operate with wide energy headroom under 5 kW solar input
  • Water outputs scale reliably to ~60+ L/day
  • Modular scaling or expansion is possible with minimal infrastructure
  • Battery + thermal buffering ensures reliability through seasonal cycles
