Manual iteration, manual errors
You draw table rows one by one. Route cables manually. Re-enter data between tools. Every design change means starting the cycle again. A 50 MW layout takes weeks of work that the software should be doing for you.
The engineering system that designs utility-scale solar farms — from terrain to construction documents.
Deterministic layout, electrical, civil, and financial engines — orchestrated by AI, controlled by you. One AutoCAD/Civil 3D plugin. One backend. Three ways to access.

Three problems we saw in every solar design office
Tools that hide their reasoning
When the shading result looks wrong, can you trace it to specific geometry? When the cable loss number changes, do you know which assumption shifted? Black-box tools produce outputs without provenance. Your engineering sign-off deserves better.
Five tools, five models, zero integration
Layout in PVcase. Shading in PVsyst. Electrical in a spreadsheet. Civil in Civil 3D. Financials in Excel. Each tool holds a fragment of the design truth. None of them talk to each other. Errors compound silently.
VibeSolar runs layout, electrical, civil, shading, and financial analysis from a single model — every output deterministic, every assumption visible, every parameter changeable without restarting from scratch.
Four steps from site boundary to construction documentation
Import Your Site
Load a DXF boundary, fetch terrain from public APIs (GUGiK NMT for Poland, others available), or draw directly in AutoCAD/Civil 3D. VibeSolar builds the 3D terrain model and computes buildable area automatically — with setbacks, exclusions, and slope classification.
Configure & Generate
Select equipment from the built-in catalog, set design constraints, and generate a complete layout in one click or one sentence to the AI assistant. The system places tables terrain-adaptively, assigns strings, routes cables in 3D, lays roads and fencing, and runs shading — all in one pass.
Review & Iterate
Run AI-powered design review (50+ engineering rules). Compare scenarios — sweep pitch, tilt, equipment across 1–50 variants with P10/P50/P90 rankings. Change any parameter. The entire pipeline recomputes in seconds. Every decision is logged.
Export & Deliver
Export EPC-ready CAD files, PVSyst-compatible shading geometry, Bill of Quantities with cost breakdown, financial models (LCOE/IRR/NPV), string plans, and executive project summaries. Multi-format: DXF, Excel, Markdown. PDF coming.
One design system. Three access paths.
Different teams have different tools, different budgets, and different workflows. VibeSolar meets you where you are.
AutoCAD/Civil 3D Plugin — The Engineering Workflow
For engineers who need full design control in their professional CAD environment. 96 ribbon commands, 32 WPF dialogs, real-time row-by-row layout streaming, bidirectional entity sync. This is where detailed engineering happens — native, fast, and fully integrated.
Best for: PV design engineers, EPC technical teams, detailed engineering phases.
Cloud Web Access — The Browser Workflow
For team members who need design outputs without an Autodesk license. Upload a DXF site boundary through any browser, configure parameters, and generate layouts using the same backend engines. Review results, compare scenarios, export reports. Not a replacement for AutoCAD/Civil 3D — a complementary path that expands who can use VibeSolar.
Best for: Development teams, pre-feasibility screening, project managers, remote site assessment.
Automation Agent — The Background Workflow
For companies that want throughput at scale. A folder watcher detects new project files in a workspace directory, triggers design generation through the backend, and delivers completed results — without a human clicking “generate” for each run. Integrates with existing file-based workflows and CI/CD pipelines.
Best for: Batch pre-screening, integration with existing pipelines, high-volume preliminary design.
Complete pre-construction engineering in one system
Each discipline runs its own deterministic engine. All disciplines share one project model. Change anything — the entire design updates.

Designs that respect physical reality
Most PV design tools treat the site as a flat polygon with a slope number. VibeSolar works in actual 3D terrain — and that changes everything.
Tables split when slopes exceed equipment limits. Cables follow terrain with calculated burial depths and 45° risers. Roads adapt to grade. Structural models carry real mounting detail — not just a rectangle on a map.
Mixed-frame layouts place different table families in the same design — tracker rows in flat zones, fixed-tilt in sloped areas, different module counts per section. The layout engine doesn't force one configuration onto an entire site.
This is the level of structural detail that survives contact with construction.
Explore the design space — don't guess through it
Generate 1–50 design variants by sweeping pitch, tilt, setback, gap, and equipment simultaneously. Each scenario runs the full deterministic pipeline — not an approximation.
- Generate 1-50 design variants by sweeping pitch, tilt, setback, and gap ranges simultaneously
- Compare equipment options — test multiple module models, inverter types, and mounting configurations side by side
- Automatic yield estimation with latitude-based GHI proxy and LCOE calculation (EUR/MWh)
- P10 / P50 / P90 capacity percentile rankings with uncertainty quantification and confidence scoring
- 7 optimization strategies: balanced, maximum density, low earthworks, max yield, min LCOE, maintainability, schedule-safe
- Fully deterministic — each scenario runs the same layout engine, just with different parameters. Reproducible via seed control.
- Results ranked with composite scoring across density, earthworks, yield, and financial metrics
- Probabilistic models for high-uncertainty inputs — terrain variability, irradiance deviations, energy price fluctuations, and module degradation curves are captured through ensemble analysis rather than single-point assumptions
AI that explains itself — not a black box with a chat window
VibeSolar uses AI for orchestration, intent interpretation, and learning — not for generating geometry. The engineering engines are deterministic. The AI makes them accessible.
AI Design Assistant
Describe what you want in natural language (Polish or English). The intent parser converts your request into validated design parameters. The action dispatcher maps those to executable CAD commands — with safety confirmation before anything writes to your model.
ML Edit-Learning (Deployed)
The system observes how you refine layouts — which tables you move, which cables you reroute, which zones you clear. It infers design intent from 7 rule-based patterns with confidence scoring. Over time, it learns your organization's engineering preferences.
Design Review
50+ automated checks across capacity balance, electrical compliance, civil feasibility, and grid compatibility. Each check explains what it found and why it matters. Every AI interaction is logged. Every inference is scored. Every decision has a traceable path.
