Services
What kind of design do you need?
Solar Design Lite
Best for DIY homeowners, off-grid systems, or early-stage planning. Ideal when you need system sizing, layout, and performance insights without permits or engineering.
Solar Permit Planset (Stamped)
For projects requiring permitting with either structural or electrical engineering approval. Common for residential grid-tied systems in many jurisdictions.
Solar Plan Set
Designed for installs that need technical drawings but don’t yet require stamped engineering. Great for installers, advanced DIY projects, or pre-permit planning.
Commercial Design
Built for larger, more complex systems. Ideal for commercial, multi-building, or high-capacity projects needing expanded engineering, coordination, and permitting support. Our team specializes in small commercial projects ready for permitting.

Frequently Asked Questions (FAQ)
Do you handle my permits?
No. You will be responsible for submitting your own building, electrical, and utility interconnection applications.
That said, your Engineered PowerPlan includes permit-ready documentation designed to meet AHJ and utility requirements. We also offer optional paid support services if you’d like assistance navigating the permitting process.
Do I need a licensed contractor to pull permits?
In some jurisdictions, yes. While PowerPlan provides professional solar design plansets suitable for permitting, certain AHJs (Authorities Having Jurisdiction) require a licensed contractor of record to be listed on the permit application.
If you’re a homeowner or DIY installer, we recommend checking local permitting requirements early in the process. We’re happy to design to code—but permit submission rules vary by location.
How should I budget for shipping?
Solar equipment is heavy—and shipping costs can add up. As a general guideline, plan for shipping to run approximately 10–15% of your total materials cost.
Actual shipping costs depend on factors like pallet count, freight class, delivery location (residential vs. commercial), and liftgate requirements. We’ll always aim to help you minimize surprises where possible.
What happens if I need a plan revision?
Revisions are a normal part of the design and permitting process. Minor updates—such as small layout tweaks or AHJ comments—are typically handled quickly.
More significant changes (system size adjustments, structural changes, equipment swaps, or site condition updates) may require an additional revision fee, depending on scope. If that’s the case, we’ll clearly communicate next steps before proceeding so there are no surprises.
When do utilities require a licensed electrician?
Some utilities require a licensed electrician for final system sign-off or approval, even if the homeowner submits the interconnection application themselves.
Utility requirements vary by service territory, so it’s important to confirm electrician involvement early—especially for grid-tied systems.
