If you’ve been in the solar industry long enough, you know one universal truth:
Everyone wants the design done yesterday… until the inspector finds a missing label.

As solar engineers, we get it. Installers live in a world of tight schedules, impatient homeowners, and AHJs who somehow always find that one detail you didn’t even know existed. But here’s the thing — in solar design, speed and accuracy are not enemies. They’re more like peanut butter and jelly: you need both, or it’s just weird.

Let’s break down why neither can be compromised — and why choosing one over the other can cost you delays, extra money, and a lot of phone calls you don’t want to make.

Speed Matters — More Than Most Installers Admit

When installers ask for “super-fast turnaround,” it’s not just a preference — it’s survival.

• Homeowners expect installation timelines between 2–4 weeks.
• Sales pipelines depend on momentum.
• Many AHJs take 5–10 business days to respond — so delays before submission are painful.
• Installers who tighten their design turnaround often see a 20–25% increase in monthly installs.

Speed matters. But speed alone is not the hero of the story.

Accuracy Matters Even More (Ask Any Installer Who’s Failed an Inspection)

Here’s a not-so-fun industry fact:
Nearly 70% of permit revisions come from electrical errors.

From our side of the desk (and multiple CAD windows), the most common issues we see are:

• Incorrect wire or breaker sizing
• NEC 705 & 310 violations
• Improper panel placement on complex roofs
• Missing labels or mismatched equipment specs

These small mistakes add big delays:

Every inaccurate design typically adds 2–10 days to the project timeline.
Multiply that across a month… and your schedule looks like a Jenga tower leaning dangerously to the left.

The Real Cost of Choosing Speed Over Accuracy

We all know that one contractor who says,
“Just get me something quick, I’ll figure it out on site.”

Spoiler: they never figure it out on site.

Instead, they call from the roof asking where the conduit magically disappeared to — like we buried it under the shingles.

Speed without accuracy leads to:

• Failed inspections
• Extra material runs
• Confused installation crews
• Surprised homeowners (never a good thing)
• A permit reviewer who now knows your entire life story

The Sweet Spot: Fast and Accurate

The right engineering partner should provide:

✔ Fast Turnaround (24–48 hours for standard jobs)

No excuses, no shortcuts.

✔ NEC-Perfect Accuracy

From 2017 to 2023 code cycles — everything spot-on.

✔ Clear, Installer-Friendly Drawings

Your crew should be able to follow the plan before their morning coffee kicks in.

✔ AHJ & Utility Expertise

There are over 1,200 AHJs in the U.S.
You need someone who understands the difference between “California strict” and “Texas flexible.”

Why You Shouldn’t Have to Choose

Speed drives efficiency.
Accuracy drives quality.
But choosing between the two? That’s a decision no installer should ever have to make.

The truth is simple:

A great solar engineering partner delivers both — consistently, predictably, and without drama.

Because in this industry, surprises are for birthdays…
not for inspections.
