Hello, I am seeking a qualified solar design professional or engineering firm to produce a complete, permit-ready off-grid solar + battery + generator design package for a residential project located in Coconino County, Arizona (Williams, AZ area). This is an off-grid installation (no utility interconnection). The design must be suitable for AHJ submission and permit approval in Coconino County. PROJECT OVERVIEW • Ground-mounted PV system (30 panels total, approx. 13.5 kW DC) • Mounting preference: pressure-treated wood posts with aluminum or Unistrut rails • Inverter: EG4 FlexBOSS21 (48V split-phase) • Batteries: EG4 PowerPro (2 units, expandable architecture) • Generator: Generac Guardian 7171 (10kW) • Generator integration: 2-wire start via inverter AGS (no standalone ATS preferred unless required) • Two separate 100A cabin panels • Shared solar shed housing inverter, batteries, and generator • Underground feeder runs: approximately 75 ft + 15 ft (trenchable route) • Automatic load shedding required for EV charger and dishwashers during low SOC or generator operation This is not a grid-tied net-metered system. This is a true off-grid hybrid system with generator backup. SCOPE OF WORK REQUIRED Electrical Design: • Complete permit-ready PDF plan set • Single-line diagram (SLD) • PV stringing + MPPT configuration • Battery integration and system architecture • Generator integration (2-wire AGS via inverter) • NEC load calculations (two cabins + shared loads) • Conductor sizing • Voltage drop calculations • Grounding and bonding details • Overcurrent protection sizing • Underground feeder design and trench detail • Panel schedules (both cabins) • Load shedding logic design Structural Design – Ground Mount: • Site-specific wind and snow load calculations (Coconino County) • Structural design per IBC and applicable codes • Post spacing and embedment schedule • Uplift, lateral, and frost depth considerations • Site Class D assumption if geotechnical report not provided • Wood post + rail structural detailing • Structural calculation report suitable for permit submission DELIVERABLES • Complete permit-ready stamped PDF plan set • Electrical calculation package • Structural calculation package • Arizona-licensed PE stamps (electrical and structural on required sheets) IMPORTANT REQUIREMENTS Please confirm the following in your response: 1. Do you provide Arizona-licensed Professional Engineer (PE) stamping? 2. Are structural and electrical stamps provided under one coordinated submittal? 3. Are PE stamps included in your quoted price or priced separately? 4. Can you provide the Arizona PE license number for verification? 5. Is your design site-specific (wind/snow derived for this project location)? 6. What is your total fixed, all-in price for the full scope described above? 7. What is your estimated turnaround time? 8. How many revisions are included? 9. Have you completed off-grid hybrid systems using EG4 equipment before? Please also share a sample permit-ready stamped plan set for a similar off-grid ground-mount project (not just a PV production report or PV*SOL simulation output). I am not looking for energy modeling only. I require a construction-level permit package suitable for AHJ approval. This project will move forward quickly once scope and pricing are aligned. Thank you, Matthew

I have successfully developed and secured approvals for over 150 residential solar permit sets, maintaining a high first-pass rate with both AHJs and utility providers across various jurisdictions. My background includes a deep understanding of standard roof-mount configurations and complex electrical interconnections, ensuring that every design I produce is both code-compliant and optimized for efficient field installation. By prioritizing local fire codes and structural load requirements from the outset, I help contractors avoid the costly delays associated with technical corrections and repetitive revision cycles, ensuring a seamless transition from design to construction. My technical approach centers on creating a high-fidelity AutoCAD drafting package that includes a comprehensive site plan, detailed array layout with precise setbacks, and structural attachment details tailored to specific roofing types. I will design a code-compliant electrical single-line or three-line diagram (SLD/3LD) that clearly defines conductor sizing, OCPD ratings, and grounding methods in strict accordance with NEC 2020/2023 standards. Furthermore, the set will incorporate a complete signage and labeling schedule, alongside detailed racking specifications and mounting calculations to ensure the structural integrity of the installation meets all local wind and snow load requirements for your specific region. Does this specific project require a PE stamp for structural or electrical sheets, or are you looking for the design package exclusively? Additionally, could you confirm if we are working with a standard main lug connection or if a line-side tap will be necessary based on the existing busbar capacity? I am available to discuss these technical details or review your site survey data whenever you're ready; feel free to message me here or schedule a brief call to finalize the project timeline and get the submittal moving.
