Solar Design & Estimation Engineer

About the role

The Solar Design & Estimation Engineer is responsible for creating accurate solar PV system designs, material take‑offs, cost estimates, and technical proposals for U.S. residential and commercial projects. The role works closely with sales, engineering, permitting, and project management teams to ensure timely and high‑quality deliverables.

Key responsibilities

• Prepare detailed solar PV system designs using Aurora Solar, HelioScope, AutoCAD, and related engineering tools.
• Perform accurate material take‑offs (MTO/BOQ) for modules, inverters, racking, electrical equipment, and balance‑of‑system components.
• Develop project cost estimates, pricing, and labor/material assumptions based on scope.
• Review site information, satellite imagery, structural/electrical details, and customer requirements to create feasible designs.
• Produce layouts, single‑line diagrams, equipment specifications, and documentation in compliance with U.S. codes and utility standards.
• Support commercial pre‑sales proposals with precise technical and financial inputs.
• Identify design conflicts, scope gaps, material needs, and potential risks before proposal submission.
• Maintain standardized estimating templates, equipment databases, pricing references, and design standards.

Required profile

• Bachelor’s degree in Electrical Engineering, Renewable Energy, or a related field.
• Experience in solar PV design, estimation, and material take‑offs.
