SolarEdge Designer to AutoCAD: The Complete Workflow

You designed a system in SolarEdge Designer. The customer approved the proposal. Now you need construction documents in AutoCAD.

This is where most teams lose hours. SolarEdge Designer is built for proposals, production estimates, and equipment configuration. It is not built for permit-ready construction drawings. So you're left recreating work that, in some form, already exists.

Here are your three options for getting from SolarEdge Designer to AutoCAD, and why one of them eliminates most of the manual work.

The Problem: SolarEdge Designer's Exports Weren't Built for CDs

SolarEdge Designer outputs two things: a DXF file and a PDF report.

The DXF export gives you polylines representing panel outlines and string connections. No block references, no data association, no layer organization that matches your CAD standards. These are purely visual elements. You can bring them into AutoCAD, but all you get is geometry to trace over.

The PDF report actually contains more useful information: the panel layout with string assignments, optimizer placements, inverter mappings, and system configuration details. It is designed for human reading, but it turns out a parser can extract structured data from it too.

Neither export gives you construction-document-ready CAD objects. But one of them gets you much closer than the other.

Option A: Manual Recreation from DXF

This is what most teams do today.

1. Export DXF from SolarEdge Designer
2. Import into AutoCAD
3. Trace over the panel positions, replacing polylines with your standard panel blocks
4. Visually reference the SolarEdge layout to determine string assignments
5. Manually draw strings, homeruns, and labels
6. Manually measure cable lengths

It works. It's accurate if you're careful. And for a 200-panel commercial rooftop, it takes a few hours of tedious drafting work that adds no engineering value.

The DXF import is essentially a background image that you draw on top of. You're doing double work: the layout was already done in SolarEdge, and now you're recreating it by hand in a different tool.

Option B: Leaf PDF Import

Instead of importing the DXF, import the SolarEdge Designer PDF report directly into AutoCAD using Leaf.

Here's the step-by-step:

Step 1: Export the PDF from SolarEdge Designer

In SolarEdge Designer, download the full system report PDF. This is the multi-page document with the layout diagram, string table, and equipment summary. Not a screenshot, not a cropped image — the full report.

Step 2: Run IMPORTSOLAREDGEPDF in AutoCAD

With Leaf loaded, type IMPORTSOLAREDGEPDF at the command line. Select your PDF file.

Leaf parses the PDF and extracts:

• Panel positions — each module becomes an AutoCAD entity at its correct relative position
• String assignments — which panels belong to which string, preserved from SolarEdge's configuration
• Optimizer placements — optimizer-to-panel mapping from the SolarEdge layout

The result is a set of CAD objects positioned according to the SolarEdge layout, with string data already associated.

Step 3: Scale and Position

The imported geometry needs to be scaled and positioned to match your site plan. SolarEdge Designer's coordinate system doesn't map directly to your survey or site plan coordinates.

Tips for this step:

• Use a known dimension (building edge, array width) to calculate the correct scale factor
• Verify panel counts match between the SolarEdge report and the imported geometry
• Align to your site plan reference points

Step 4: Run the Standard Leaf Workflow

Once positioned, the standard Leaf commands take over:

• PANELGROUPCREATE — Define panel groups if not already set from the import
• SOLVE — Generate or verify stringing with voltage window compliance
• HOMERUNS — Route homeruns from string endpoints to inverter locations using K-means optimized pathing
• CABLEEXPORT — Export circuit lengths and string data to Excel

Because the imported objects carry string assignment data, Leaf can work with them immediately. You're not starting from scratch — you're continuing from where SolarEdge Designer left off.

Step 5: Finalize Construction Documents

Add your title block, notes, and any additional annotations your jurisdiction requires. The electrical single-line diagram, load calculations, and other engineering documents are separate deliverables that Leaf doesn't produce — those are engineering, not drafting.

Option C: Start Fresh in AutoCAD

Sometimes the SolarEdge layout doesn't reflect what you actually want to build. The proposal layout was preliminary, the customer changed the roof area, or the structural review eliminated half the available mounting zones.

In those cases, ignore the SolarEdge export entirely:

1. Place your panel blocks manually on the site plan
2. Create panel groups with PANELGROUPCREATE
3. Run SOLVE for stringing
4. Run HOMERUNS for homerun routing
5. Run CABLEEXPORT for cable lengths

This takes longer than the PDF import path, but it's still faster than fully manual drafting because Leaf handles the stringing, routing, and cable length calculation.

DXF Export vs PDF Import: Side by Side

| | SolarEdge DXF Export | Leaf PDF Import | |---|---|---| | What you get | Polylines, text labels | Panel entities with string data | | Data association | None — just geometry | String assignments preserved | | Time to usable CAD | Hours (manual recreation) | Minutes (import + scale + position) | | Downstream automation | None — everything manual | Full Leaf workflow available | | Cable length export | Manual measurement | CABLEEXPORT to Excel | | Homerun routing | Draw by hand | HOMERUNS with K-means optimization |

When to Use Each Approach

Use Leaf PDF Import when:

• The SolarEdge layout is close to final
• You want to preserve the string assignments from the proposal
• The project is large enough that manual recreation is painful (roughly 100+ panels)

Start fresh in AutoCAD when:

• The layout changed significantly after the proposal
• You need a different stringing configuration than what SolarEdge generated
• The SolarEdge layout was preliminary and you're doing the real engineering now

Use the DXF as a background reference when:

• You want to visually compare your AutoCAD layout against the proposal
• You're using the DXF as a sanity check, not as a starting point

The Bottom Line

SolarEdge Designer is the right tool for proposals. AutoCAD is the right tool for construction documents. The question is how much manual work sits between them.

The DXF export makes you redo everything. The PDF import lets you carry forward the work that was already done and pick up where SolarEdge left off — with intelligent CAD objects instead of dumb polylines.
