Hiring a remote solar design engineer? What to vet: PVsyst and AutoCAD skills, NEC code, interconnection experience, and the NABCEP credential.

What to look for in a remote solar design engineer

A strong remote solar design engineer combines PV design software (PVsyst, Helioscope, AutoCAD), fluency in the National Electrical Code and local interconnection rules, and real project experience across the system types you build. The clearest third-party signal of competence is a NABCEP credential. Vet for those before rate or location.

Demand is the backdrop: the US solar industry now employs more than 250,000 people and keeps expanding, so experienced solar design engineers are scarce, and hiring remotely widens the pool. But "solar experience" on a résumé spans residential rooftop to utility-scale, and the skills don't transfer cleanly. Here's how to tell the difference.

PV design software fluency

The daily tools are PVsyst and Helioscope for production modeling and shading analysis, plus AutoCAD for layouts and single-line diagrams. Ask what they model themselves versus what they hand off: someone who can run a shading study and size strings is worth more than someone who only drafts the final sheets.

National Electrical Code knowledge

Solar design lives and dies on the NEC (NFPA 70), especially Article 690 for PV systems: rapid shutdown, conductor sizing, grounding, and overcurrent protection. A designer who can't speak to Article 690 requirements will produce drawings that fail review.

Interconnection and permitting experience

Every project has to clear a utility interconnection application and an authority-having-jurisdiction (AHJ) permit, and both vary by location. Ask which utilities and jurisdictions they've actually submitted to. Like building codes, interconnection rules are local, not generic.

System-type match

Residential rooftop, commercial and industrial (C&I), and utility-scale are different disciplines. A residential rooftop expert may have never sized a ground-mount combiner box. Vet for the system type you actually build, not "solar" in the abstract.

The NABCEP credential

The NABCEP PV Design Specialist credential is the industry's recognized certification for solar design, and by 2024 roughly 30% of solar-company employees held a NABCEP credential, up from 11% the year before. It isn't a license, but it's the clearest third-party signal that someone knows the craft.

Remote-work fundamentals

Everything that makes any remote hire work still applies: time-zone overlap for real-time review, clear documentation, and proactive communication. The same discipline behind the skills to look for in any remote technical hire applies here, and time-zone overlap decides whether reviews happen same-day or next-day.

The signals worth more than a rate quote

• PV software fluency (PVsyst/Helioscope), not just drafting.
• NEC Article 690 knowledge: the code solar runs on.
• Interconnection and AHJ experience in real jurisdictions.
• System-type match: residential, C&I, or utility-scale.
• A NABCEP credential as the third-party competence signal.

The part the résumé won't tell you

"5 years in solar" could mean five years of rooftop, or five years of exactly your project type. The checklist above is how you find out before the first design review.
