- Prepare and maintain design drawings using AutoCAD and other design software, including:
- PV module layouts
- Equipment layouts
- Single-line diagrams (SLDs)
- Conduit and cable routing
- Equipment connection details
- Other drawings required for permitting, engineering, utility applications, and construction

- Assist with equipment selection and system sizing, including PV modules, inverters, transformers, switchgear, disconnects,



electrical distribution equipment, and related balance-of-system components.
- Assist with basic electrical calculations, equipment ratings, cable sizing, voltage drop, and other design calculations under the guidance of senior designers and engineers.
- Prepare system specifications, equipment schedules, design packages, and supporting technical documentation.
- Coordinate with structural and electrical engineers to incorporate engineering requirements and comments into project drawings.
- Revise designs based on customer comments, engineering reviews, and permitting authority and utility requirements.
- Provide technical support to project management, sales, procurement, and construction teams throughout the project lifecycle.
- Maintain awareness of emerging solar technologies, inverter systems, battery energy storage systems (BESS), and grid interconnection requirements.
- Commercial Project Planning & Coordination
- Review project proposals, contracts, scopes of work, change orders, customer requirements, and other project documentation to understand scope, responsibilities, deliverables, and technical requirements.
- Coordinate with customers, sales teams, project managers, engineers, subcontractors, suppliers, and installation teams to ensure design requirements are clearly communicated.




- Track design activities and outstanding technical items to support project schedules.
- Identify potential design conflicts, constructability issues, missing information, and project risks, and communicate them to the appropriate project team members.
- Assist project managers with technical documentation, material requirements, procurement information, and construction coordination.
- Support multiple commercial solar projects simultaneously and prioritize tasks based on project schedules and business requirements.
- Permitting, Code Compliance & Utility Interconnection
- Coordinate with electrical and structural engineers to ensure designs meet applicable building codes, electrical safety codes, engineering standards, and Authority Having Jurisdiction (AHJ) requirements.
- Support applications and technical submissions to Local Distribution Companies (LDCs) and other utilities.
- Assist with the preparation and review of utility interconnection documents, including single-line diagrams, equipment information, protection requirements, metering requirements, and supporting technical documentation.
- Review and respond to technical comments from municipalities, utilities, engineers, and other reviewing authorities with guidance from senior team members.
- Maintain organized records of submissions, approvals, drawings, and project correspondence.
- Construction & Project Delivery Support
- Provide technical support during procurement, installation, commissioning, and project closeout.
- Review construction-related questions and Requests for Information (RFIs), and coordinate responses with engineers a
