Renewable Energy Engineering Services
Solar PV, wind, battery storage, grid interconnection, utility coordination, and PE-stamped permitting — delivered by licensed engineering professionals nationwide.
End-to-end engineering for the clean-energy build-out.
Renewable energy projects move forward when the engineering is right. Solar PV, wind, and battery storage systems all require coordinated electrical, structural, and interconnection design — plus permit-ready drawings stamped by a licensed Professional Engineer in the project state.
EngineerMint connects developers, EPCs, asset owners, utilities, and municipalities with renewable energy engineering professionals across the country. Every record on the platform can be cross-checked against the relevant state licensing board for live verification.
Whether the project is a 200 kW commercial rooftop array, a 20 MW community solar farm, a behind-the-meter BESS, or a microgrid for resilience, the same engineering disciplines are required — just at different scales.
What renewable energy engineers do
From feasibility through energization — engineering services that get clean-energy projects designed, permitted, and connected.
Solar PV system engineering
Electrical and structural design for rooftop, ground-mount, and carport PV — single-line diagrams, racking calcs, inverter and string sizing, IFC drawings.
Wind energy engineering
Site assessment, turbine selection support, foundation review, collection system design, and repowering studies for distributed and utility-scale wind.
Battery storage & BESS engineering
BESS sizing for demand charge management, peak shaving, backup, and solar-plus-storage — with NFPA 855 and UL 9540 fire-code review.
Grid interconnection studies
Pre-application reports, IEEE 1547 review, protection coordination, short-circuit and voltage impact studies, and utility application support.
Utility coordination
Direct coordination with the utility's interconnection desk, metering, telemetry, and any required system upgrades through energization.
Permitting & PE-stamped drawings
Permit-ready drawing sets stamped by a licensed Professional Engineer in the project state, with AHJ engagement to clear comments in one cycle.
How to hire a renewable energy engineering firm
The right firm reduces risk and keeps a project on schedule from feasibility through interconnection. Before signing an engineering services agreement, confirm experience with similar project sizes, in-state Professional Engineer licensing, interconnection workflow with your utility, and a clear scope of deliverables and revision rounds.
Our full guide — How to hire a renewable energy engineering firm — walks through the questions to ask, what stamped deliverables to expect, and how to compare proposals across solar PV engineering, battery storage engineering, and grid interconnection.
All credentials should be independently verified with the appropriate state licensing board. EngineerMint surfaces real records sourced from those boards so project owners can confirm a Professional Engineer is in good standing before engagement.

Frequently asked questions
What does a renewable energy engineering firm do?+
Renewable energy engineering firms design solar PV, wind, and battery storage systems — including electrical layout, structural review, grid interconnection, utility coordination, and the PE-stamped drawings required for permitting.
Do I need a licensed PE for a solar or storage project?+
Most grid-connected commercial and utility-scale solar and battery projects require stamped electrical and structural drawings from a licensed Professional Engineer in the project state.
How long does renewable energy engineering take?+
Residential PV can be turned around in days. Commercial PV plus storage typically takes 4–8 weeks through permit set. Utility-scale projects run six to eighteen months through interconnection and IFC drawings.
What does it cost?+
Commercial PV plus storage runs roughly $0.05–$0.15/W in engineering fees. Utility-scale programs scale into six and seven figures depending on study and interconnection scope. Use the AI Estimator for a project-specific range.
Can one firm cover solar, battery, and interconnection?+
Yes — most renewable energy engineering firms cover electrical, structural, and interconnection in-house. For utility-scale or specialty work (offshore wind, large BESS) an owner's engineer plus specialty consultants is common.
