I’m looking for a solar engineer who can take my commercial site—rated for well over 200 kW of demand—and turn it into a fully-documented, off-grid photovoltaic solution. The scope covers everything from the initial load assessment right through to the final AutoCAD drawings. Here is what I need you to deliver: • A complete PV array layout in AutoCAD, showing module strings, row spacing, and orientation that fits the available roof and ground space. • Structural details for the mounting system, including material specifications and anchoring. • Sizing calculations for the battery storage bank to keep the site running independently, plus the inverter configuration that matches both peak and surge loads. • Single-line and wiring diagrams, cable schedules, and protection schemes. • A concise bill of materials with component ratings and quantities. All calculations—irradiance, energy yield, derating factors, and autonomy days—must be clearly shown so the design can be verified or audited later. Use your preferred design software, but the final drawings must arrive in DWG/DXF along with an unlocked PDF set. I’ll review the submission against the above items and the accuracy of your electrical and structural calculations. Let me know your estimated turnaround time and any additional data you’ll need from me to start.

Hi, I can support the engineering design of your off-grid commercial solar PV system, including load analysis, PV sizing, battery storage, inverter configuration, electrical protection, BOM, and AutoCAD documentation. I would begin by reviewing the site location, interval load profile, peak and surge demand, roof/ground dimensions, structural details, required autonomy, critical loads, equipment preferences, and applicable local codes. I’ll then calculate irradiance, energy yield, system losses, battery capacity, inverter loading, cable sizes, voltage drop, and protection requirements. I’m experienced with commercial solar design, off-grid systems, battery storage, AutoCAD layouts, single-line diagrams, cable schedules, structural mounting concepts, and technical calculations. Deliverables can include: * PV array layout in DWG/DXF * Stringing, spacing, and orientation plan * Battery and inverter sizing * Energy yield and autonomy calculations * Single-line and wiring diagrams * Cable and protection schedules * Mounting and anchoring details * Bill of materials * Unlocked PDF drawing set * Design assumptions and calculation notes For a system above 200 kW, I recommend beginning with a paid concept and load-assessment milestone, then confirming the full engineering fee after reviewing site data. I’ll focus on a technically auditable, practical, and scalable design. Best regards Ankit

I am a Licensed Professional Electrical Engineer with 6+ years of experience in commercial solar PV and BESS system design, delivering fully documented off-grid and grid-tied solutions from initial load assessment through to permit-ready AutoCAD drawing packages. I have delivered comparable projects including a 1MWp hybrid solar and BESS mini-grid in Somalia covering full SLDs, LV switchboard design, cable sizing, and protection coordination, and multiple US-based off-grid solar permit packages including a 36-panel dual-inverter battery system in South Carolina — all with clearly shown calculations for energy yield, derating factors, battery autonomy, and DC/AC ratio. For your 200kW+ commercial off-grid site I will deliver a complete PV array layout in AutoCAD (DWG/DXF + unlocked PDF), battery bank and inverter sizing calculations with full autonomy day analysis, single-line and wiring diagrams, cable schedules, protection schemes, and a detailed BOM with component ratings and quantities. All irradiance, energy yield, and derating calculations . I work primarily in PVsyst for energy modelling and AutoCAD Electrical for drawings, with OpenSolar for layout visualisation where needed. To get started I will need your site location, available roof/ground area, load schedule or utility bills, and any preferred equipment brands. I can deliver a first draft within 1-2 days. I am available immediately to start and discuss. Best regards, Tahir Saleem

The result was a fully optimized solution that met the client's energy demands while ensuring long-term reliability. Briefly, I have over 5 years of experience in solar engineering, specializing in off-grid solutions for commercial clients. My expertise in load assessments, PV array layouts, and battery storage systems aligns perfectly with your project requirements. I understand your goal of creating a self-sustaining off-grid solar solution and ensuring accurate documentation for future verification. By meticulously calculating irradiance, energy yield, and autonomy days, I will design a comprehensive system that meets your needs. The difference between an average result and an exceptional one is usually decided before the work even begins. Regards, MobiDealer
