Off-Grid Solar PV System Design

I am looking for a qualified solar engineer to take my off-grid project from concept through to a build-ready package. The site is currently without grid access, so the system must be fully self-sufficient and sized to match daily household loads plus a modest growth allowance.

What I expect you to cover
• Accurate load assessment and array sizing
• Selection of panels, MPPT inverter/charger, battery bank, and protective gear that balance cost, longevity, and efficiency
• Single-line diagrams, wiring schedules, and mounting layout drawings suitable for a local electrician to follow
• A clear bill of quantities with unit pricing and a total project cost estimate
• A brief technical proposal that explains your design choices, expected performance, and maintenance considerations

Please attach a detailed project proposal showing similar off-grid work you have completed, the software you will use (e.g., PVsyst, HOMER, AutoCAD, Excel), and the deliverables I will receive at each milestone.

The timeline is flexible; accuracy and practicality matter more than speed. Open to your recommendations on component brands and any innovative ideas that could improve reliability or lower long-term operating costs.
