Skyfire vs SolarEdge Designer (2026)
SolarEdge Designer is a free tool that helps configure SolarEdge systems — great for string sizing and equipment selection within the SolarEdge ecosystem. Skyfire is an equipment-agnostic permitting platform that generates PE-stamped, AHJ-compliant plan sets. If you just need to configure SolarEdge strings, their free tool works. If you need permit-ready output for any equipment brand, Skyfire is the answer.

Where Skyfire Wins
Equipment-agnostic design
Skyfire supports SolarEdge, Enphase, Tesla, and other major inverter and battery brands. SolarEdge Designer only works with SolarEdge equipment — if you ever diversify your product offerings, the tool cannot follow.
Complete permit-ready output
Skyfire generates full permit packages including plan sets, line diagrams, structural calculations, and electrical details. SolarEdge Designer produces equipment configuration documents, not permit-ready plan sets.
Compliance engine and AHJ database
Skyfire automatically checks designs against local AHJ requirements, NEC codes, and building standards. SolarEdge Designer has no compliance checking — it focuses on equipment configuration, not code compliance.
PE stamps included
Skyfire includes PE stamps with every plan set. SolarEdge Designer does not produce stampable engineering documents.
Where SolarEdge Designer Might Be Better
Free for SolarEdge users
SolarEdge Designer costs nothing for SolarEdge customers. If you exclusively use SolarEdge equipment and only need help with string sizing and system configuration, it is hard to argue with free.
Deep SolarEdge integration
The tool is built by SolarEdge for SolarEdge. String sizing, optimizer placement, and compatibility checking are precise and up-to-date with the latest SolarEdge product line.
Accurate SolarEdge performance estimates
Because it knows SolarEdge equipment intimately, the performance modeling for SolarEdge-specific configurations is reliable and accounts for optimizer-level behavior.
Pricing Comparison
SolarEdge Designer is free — there is no cost if you are a SolarEdge user. Skyfire charges per plan set generated. The comparison is not really free vs. paid, though. SolarEdge Designer helps you configure equipment; Skyfire produces permit packages. The real cost comparison is Skyfire's per-plan fee versus the labor, third-party PE stamp fees, and time spent manually creating permit packages from SolarEdge Designer output. For most installers doing more than a few permits per month, Skyfire's cost is a fraction of the manual alternative.
Choose Skyfire if you...
- You need permit-ready plan sets, not just equipment configuration documents
- You use inverter brands beyond SolarEdge
- You want automatic compliance checking against local AHJ requirements
- You need PE stamps included in your plan sets
- You are tired of manually converting design documents into permit packages
Choose SolarEdge Designer if you...
- You exclusively use SolarEdge equipment and only need string sizing help
- You have a separate permitting workflow and just need equipment configuration
- Cost is your primary concern and you handle permitting entirely manually
- You want precise SolarEdge optimizer placement recommendations
- You do very few installs and the manual permitting process is manageable
Switching Scenario
An installer in New Jersey had been using SolarEdge Designer for string sizing, then manually building permit packages in AutoCAD — a process that took 3–4 hours per project. When they started adding Enphase to their product lineup, they lost even the SolarEdge Designer step for half their projects. Switching to Skyfire gave them a single permitting workflow for all equipment brands. Their permit assembly time dropped from hours to minutes, and they eliminated the $150 per-project PE stamp fee they had been paying a third-party service. They still use SolarEdge Designer occasionally to double-check optimizer layouts on complex roof geometries.
Frequently Asked Questions
Is SolarEdge Designer really free?
Yes, SolarEdge Designer is free for SolarEdge customers. It is a genuine benefit of the SolarEdge ecosystem. However, it is a design configuration tool, not a permitting platform — the permit package still needs to be created separately.
Can SolarEdge Designer produce permit-ready documents?
No. SolarEdge Designer produces string sizing reports and system configuration documents. These are useful inputs for a permit package, but they are not a complete, submittable permit set. You still need plan sets, line diagrams, structural details, compliance verification, and PE stamps.
Can I use SolarEdge Designer and Skyfire together?
Yes. Some installers use SolarEdge Designer for initial equipment configuration and then use Skyfire to generate the complete permit package. This works well if you want SolarEdge-specific optimization combined with fast, compliant permitting.
What if I use both SolarEdge and Enphase?
SolarEdge Designer only supports SolarEdge equipment. If you install multiple brands, you need a separate tool for non-SolarEdge jobs anyway. Skyfire supports all major brands in a single platform, which simplifies your workflow.
Does SolarEdge Designer work for commercial projects?
SolarEdge Designer supports some commercial configurations, but its primary focus is residential. Skyfire handles both residential and commercial permitting with appropriate compliance checking for each project type.
