How Branch Fits Your Solar Workflow

Branch automates the drafting work in construction document production — stringing, routing, circuit lengths. Here's how it relates to other tools in the solar workflow.

Different Tools for Different Stages

Solar projects move through distinct phases. Each phase has purpose-built tools. Branch handles the drafting-intensive construction document phase.

Proposals & Sales

Aurora, Helioscope, Solargraf, OpenSolar

Engineering

Engineer judgment, NEC analysis, structural review

Construction Documents

Branch

Installation

Field teams, commissioning

Proposal tools help win the job. Branch helps build it. Most teams use tools from multiple stages — they're complementary, not competing.

Branch vs Custom AutoLISP Scripts

Many solar engineering firms have accumulated AutoLISP routines over the years — scripts for array population, block renaming, equipment numbering, and other repetitive tasks. These work, but they're fragile and siloed.

Choose Branch if: You want purpose-built solar drafting automation that understands string sizing, voltage windows, NEC voltage window requirements, and optimizer constraints — not just generic CAD operations. Branch automates entire workflows, not individual tasks, and updates automatically without script maintenance.

Keep your LISP scripts if: You have highly specialized workflows that Branch doesn't cover, or you enjoy maintaining code. Many Branch users keep their custom scripts for non-solar tasks and use Branch for the solar-specific drafting work.

Custom AutoLISP

  • One-off scripts for individual tasks
  • Breaks when AutoCAD updates
  • Only the author can maintain it
  • No solar-specific logic

Branch Plugin

  • End-to-end solar drafting workflow
  • Maintained and updated automatically
  • Any team member can use it
  • Built-in voltage window and optimizer logic

What Branch Does

Branch is a drafting automation plugin for AutoCAD. It accepts your engineered panel layout and produces construction-document-ready output in minutes.

Panel stringing with voltage window compliance
Homerun routing with K-means optimization
Circuit and cable length export to CSV
Tag generation
SolarEdge Designer PDF import

Works in AutoCAD 2018-2026 on Windows. Also supports AutoCAD Architecture, MEP, and Electrical editions.

Frequently Asked Questions

Can I use Branch alongside other solar tools?

Yes. Many teams use Helioscope or Aurora for proposals and energy modeling, then bring the panel layout into AutoCAD and use Branch for construction document drafting. Branch also imports SolarEdge Designer PDFs directly.

Does the plugin work with BricsCAD or other AutoCAD alternatives?

Branch is built specifically for AutoCAD 2018-2026 on Windows. It also works in AutoCAD Architecture, MEP, and Electrical editions. We do not currently support BricsCAD, ZWCAD, or AutoCAD LT.

How does Branch's pricing compare?

Branch is $299/user/month with transparent, published pricing. Annual plans are $3,299/user/year. Every plan includes a 14-day free trial with no credit card required. See our pricing page for details.

What does Branch automate, exactly?

Branch automates the drafting work in solar construction document production: panel stringing with voltage window compliance, homerun routing with K-means path optimization, circuit and cable length calculation and export, and tag generation. It also imports SolarEdge Designer PDFs. Branch does not do engineering calculations like wire sizing, voltage drop analysis, or single-line diagram generation — those remain engineering decisions.

What if I need features Branch doesn't have?

We're actively developing Branch based on user feedback. If you need specific features, let us know — we prioritize requests from active users and may be able to add what you need.
