Solar-Powered AWG Concept and Technical Design
Budget: $250 – $750 USD
Freelancer Project Request – Atmospheric Water Generator Using PV Solar Power
Project Title:
Design and Development of a Solar-Powered Atmospheric Water Generator (AWG)
Project Description:
I am looking for an experienced engineer or designer to help me develop a complete concept and technical design for an Atmospheric Water Generator (AWG) powered by photovoltaic (PV) solar panels.
The goal is to produce clean drinking water from air humidity using an energy-efficient and cost-effective system suitable for hot and dry environments.
⸻
Problem Statement:
Many regions suffer from water scarcity and limited access to clean drinking water. Traditional filtration systems require an existing water source, and desalination systems are expensive and not suitable for small-scale use.
An AWG powered by solar energy offers an independent, sustainable, and off-grid solution for areas with limited water infrastructure.
⸻
Project Scope & Requirements:
1. Methodology:
The freelancer will be expected to follow a structured engineering workflow, including:
• Identifying environmental conditions (temperature, humidity, airflow) required for water extraction.
• Selecting suitable AWG technologies (condensation cooling, desiccant-based, MOF-based, or hybrid).
• Developing an energy model for solar PV input, battery storage, and system consumption.
• Creating a detailed process flow (air intake → filtration → cooling/adsorption → condensation → storage).
• Providing calculations for estimated water output per day.
⸻
2. Technical Analysis:
The deliverables should include:
• Heat transfer and thermodynamic analysis (cooling load, condensation rate, CoP if using refrigeration cycle).
• Electrical load estimation for compressors, fans, sensors, and control system.
• PV solar sizing based on local climate data (panel wattage, battery capacity, inverter requirements).
• Efficiency analysis and potential performance under different humidity conditions.
• Feasibility and optimization suggestions.
⸻
3. Material & Component Evaluation:
Provide a comparison and recommendation for key components:
• Cooling Components:
• Compressor types (DC compressor vs. traditional AC)
• Heat exchanger materials (aluminum vs. copper)
• Structure & Frame:
• Stainless steel vs. aluminum vs. polymer composites
• Adsorbent Materials (if used):
• Silica gel, zeolite, or MOF-based materials
• Electrical Components:
• Solar panels (monocrystalline vs. polycrystalline)
• Battery types (Li-ion vs. AGM)
• Charge controllers (MPPT vs. PWM)
• Water Handling:
• Food-grade tubing, filtration units, activated carbon, UV sterilization
The freelancer should justify material choices based on durability, efficiency, cost, and suitability for hot climates.
⸻
Deliverables:
• Complete technical report (PDF or Word)
• System layout diagrams and component list
• Solar sizing sheet (Excel preferred)
• Cost estimation for prototype build
• Optional: 3D model or CAD drawing of the system
⸻
Required Skills:
• Mechanical or electrical engineering background
• Experience with heat transfer and refrigeration systems
• Knowledge of PV solar systems
• Ability to perform engineering analysis and provide design calculations
• Preferably experience with AWG systems or off-grid water solutions
⸻
Budget & Deadline:
• Open to negotiation based on experience
• Expected completion: 1–2 weeks for full concept design
