Key takeaways
- Outsourced solar design turns drafting from a fixed-capacity function into an elastic one. Your install rate stops being capped by one person’s calendar.
- The real cost of an in-house bottleneck is queue time and revision cycles, not a line item. A plan set that sits four days behind other work delays an install slot you already sold.
- Avila Solar Drafting delivers solar plan sets in 2-3 business days standard and 1-2 business days on Fast Roof orders, with six months of free revisions from the order date.
- Code cycles are the hardest thing to hold in-house. NEC 2017, 2020, 2023, and 2026 are all in play across US jurisdictions right now, and the adopted cycle changes what the drawing has to show.
- Keep design in-house when volume is steady, your jurisdiction list is short, and drafting is never the reason an install slips. Outsource when any one of those stops being true.
Should you outsource solar design or keep it in-house?
Outsource solar design when your drafting queue, not your sales pipeline or your crews, is what sets your install rate. In-house drafting gives you direct control and standing knowledge of your local AHJs, but its capacity is fixed at one person’s output. Outsourced PV design is elastic: two plan sets one week, twenty the next, at a published turnaround. Most growing installers end up running both.
That is the honest answer, and it is not the answer most vendor pages give. The in-house versus outsourced PV design decision is not a referendum on whether your drafter is good. Plenty of shops have an excellent designer and still lose weeks every quarter, because one excellent designer is still one designer. The question is structural: what happens to your schedule on the week you sell nine systems instead of four?
This post walks the comparison the way an operations manager actually has to make it, in units of throughput, revision cycles, and code coverage. If you already know you need capacity and want the mechanics of how outsourced solar drafting services plug into an existing workflow, start there and come back for the decision table.
What does an in-house drafting bottleneck actually cost you?
It shows up on the calendar, not on an invoice. When one drafter is your entire design department, plan sets get served first in, first out, and the fifth job of the week waits behind four others regardless of which one you sold first or which one has a customer already asking why nothing has happened.
Work the arithmetic in install slots instead of hours. A crew that can set four residential systems a week needs four permit-ready plan sets a week, plus rework on whatever came back from the AHJ, plus the redesigns that follow a site survey finding a 100 A main breaker where the sales rep wrote 200 A. One drafter producing three complete sets a week against a four-slot crew does not fall behind by one set. The gap compounds every week the pipeline stays full, and the only relief valves are overtime, a hiring cycle you should have started three months ago, or turning down deals.
Then there is the part of the calendar you do not control at all. NREL’s research on permitting and interconnection timelines found median plan review times ranging from roughly 4.5 days to 24 days across the jurisdictions it studied, and the U.S. Department of Energy notes on its rooftop solar permitting guidance that administrative errors and backlogs can result in permitting delays. You cannot shorten an AHJ’s review clock. You control how many days pass before the package reaches the counter, and whether it arrives complete. That is the whole game, and it is why the in-house design tradeoffs look different at 20 jobs a month than they did at five.
How do in-house and outsourced PV design compare, line by line?
Compare the two models on how they behave under load, not on how they look on a slow week. Anything can produce four residential solar plan sets in a quiet month. The table below is built on the four axes that actually separate them once the pipeline is full: cost behavior, scalability, expertise, and where the risk lands when something is wrong.
| Factor | In-house PV design | Outsourced with Avila Solar |
|---|---|---|
| Capacity model | Fixed at one person’s daily output. A vacation day is a zero-output day. | Elastic. Submit two plan sets this week and twenty the next without changing anything on your side. |
| Cost behavior | A standing monthly commitment whether the pipeline holds 3 jobs or 30. | Per plan set. Pricing depends on scope and complexity — current figures are on the solar plan sets page. |
| Turnaround | Whatever the queue allows. Job five waits behind jobs one through four. | 2-3 business days standard, 1-2 business days on Fast Roof orders. |
| Code coverage | One or two people tracking NEC 2017, 2020, 2023, and 2026 across every jurisdiction you sell into. | A team drawing daily to whichever cycle the jurisdiction has actually adopted. |
| Revision cycles | Corrections compete with new work. Both slip together. | Six months of free revisions from the order date, handled outside your queue. |
| Expertise breadth | Deep where you sell most, thin everywhere else. Storage, ground mount, and EV work stretch it fast. | Residential, commercial, ground mount, storage, and EV charger sets, with PE stamps coordinated in the same order. |
| Where error risk lands | Rework falls on the same person who is already the constraint. | Avila Solar guarantees accurate solar plan sets. |
How many revision cycles is your process burning?
Count them for one quarter and the answer usually surprises people. A correction letter is not one event. It is a package pulled back, a drafter interrupted mid-job on something else, a redline read and interpreted, a revised set issued, a resubmittal, and a new position at the back of the AHJ’s review queue. Two of those in a quarter is normal. Six is a process problem.
The causes repeat. A site plan that does not match the roof as built. Setbacks drawn to a pathway requirement the jurisdiction stopped enforcing, or one it never adopted. A load calculation done as a general method when the AHJ wants the existing-dwelling load study under NEC 2023 220.87. A busbar interconnection that pencils out under one reading of NEC 2023 705.12(B)(3) and gets kicked because the plan reviewer wanted the supply-side option instead. Placards that reference the wrong rapid shutdown language for the adopted cycle.
Every one of those is preventable at the drafting table, which is why a pre-submittal pass matters more than drafting speed. Running your packages against a submission-ready design checklist before anything goes to the counter catches most of the repeat offenders, and knowing what separates good plan sets from barely acceptable ones is what keeps the second and third cycle from happening. Avila Solar plan sets are drawn to pass first-time review, and the six-month revision window means corrections do not land back on your bottleneck.
Which NEC cycle is your plan set actually drawn to?
If you cannot answer that per jurisdiction, you have found the single hardest thing to keep in-house. There is no national answer. NFPA publishes state-by-state NEC enforcement maps precisely because states sit on different editions, and local amendments move the target again underneath the state adoption.
The differences are not cosmetic. Under NEC 2017 690.12, rapid shutdown is defined by a boundary around the array, and controlled conductors outside that boundary have to be limited within 30 seconds of initiation. The same cycle’s 690.12(B)(2) set the inside-the-boundary requirement at 80 volts, enforceable from 1 January 2019, which is the change that made module-level electronics effectively mandatory in adopting jurisdictions. Draw a set to superseded language and submit it where 2020 or NEC 2023 is enforced and you have bought a correction cycle before a reviewer even opens the electrical sheet.
Storage compounds it. NEC 2023 Article 706 and the disconnecting means requirements in NEC 2023 690.13 pull a battery job into territory that a residential-only drafter may have touched twice. Structural adds a third axis: racking capacity is not something you assume from a spec sheet. IronRidge states plainly in its XR flush mount installation manual that actual system structural capacity, including spans and cantilevers, is defined by PE stamped certification letters. When a jurisdiction wants that backed by a licensed engineer, solar engineering stamps stop being a side errand and become part of the submittal package itself. With NEC 2026 published and adoption cycles beginning, the tracking burden goes up again, not down.
How do you add solar design capacity without adding headcount?
You buy capacity per project instead of per month. That is the entire mechanism, and it is why outsourcing solves a seasonality problem that hiring cannot. A drafter you bring on in March is still on the schedule in November. A plan set you order in March costs you a plan set.
Practically, the workflow looks like this. You submit a complete intake with the site survey, the equipment list, the utility and AHJ, and the roof or ground-mount details. The clock starts when the intake is complete, not when you first thought about the job, which is why shops that capture complete survey data get more out of an outsourced partner than shops that send a photo and a phone number. Standard sets come back in 2-3 business days. Fast Roof orders come back in 1-2 business days, and a Roof Order or EagleView XML on file can bring that to a single day.
The second thing outsourcing buys you is modeling and documentation you would otherwise buy separately. Yield and shade modeling in Aurora, Helioscope, or PVsyst is its own skill set and its own license stack, and pulling solar production reports from the same partner that draws the permit set means the array in the model and the array on the site plan are the same array. That sounds obvious. It is one of the more common mismatches in packages that come back for correction.
What should you look for in a solar design partner?
Ask about the failure cases, not the sales pitch. Any vendor will tell you they know code. The useful questions are narrower: which cycle do you draw to in this county, who eats the revision when a correction traces back to your sheet, how long does a revision take, and can I see finished sets rather than marketing renders.
Five things worth confirming before you send a first job:
- Published turnaround, not “fast.” A number you can schedule crews against is the only kind that matters.
- A revision policy with a window on it. Free revisions for six months is a policy. “We’ll take care of you” is not.
- Real sample sets. Look at our project portfolio or anyone else’s and check the electrical sheets, not the cover page.
- Named code cycles in the drawing set. A cover sheet that cites code articles with no edition year tells you what you are buying.
- Coverage for the work you are growing into. Storage, ground mount, EV chargers, and commercial all break a residential-only workflow.
Be equally clear about what outsourcing does not fix. It does not fix a sales team that sells systems the roof cannot carry, or a survey process that reports the wrong service size. Bad inputs produce bad sets faster, not better ones. The 12 factors behind design success are mostly upstream of the drafter, and they stay your responsibility either way. What a partner removes is the queue, the code-tracking burden, and the correction loop. It does not remove the need for a disciplined intake.
Where does Avila Solar Drafting take projects?
Nationwide, with a handful of exceptions. Avila Solar Drafting does not accept projects in APS or SRP territory in Arizona, the cities of Peoria and Phoenix, or Los Angeles County (LABD) in California. Those are firm, and they are worth knowing before you route a job. Everywhere else, including the rest of California, the work runs through the same intake and the same turnaround.
The team works out of Beaverton, Oregon, in AutoCAD, Aurora, Helioscope, and PVsyst, and draws residential, commercial, and utility-scale PV. Commercial work up to 500 kW runs self-serve; above that, it is a conversation first. More context on the shop and how it operates is on the page about Avila Solar Drafting. Note that this is a service built for solar installers. Homeowners working directly with Avila Solar pay a separate development fee, from which every business — installers, EPC firms, engineering firms, architects, developers and general contractors — is exempt.
FAQ
Should I outsource solar design or hire an in-house drafter?
Hire in-house when your monthly volume is steady, you sell into a short list of jurisdictions, and drafting has never been the reason an install slipped. Outsource when any one of those is no longer true. In-house capacity is fixed at one person’s output, so a busy week and a vacation week both cost you install slots. Outsourced solar design scales per project instead.
How fast can outsourced solar plan sets be turned around?
Avila Solar Drafting delivers standard solar plan sets in 2-3 business days and Fast Roof orders in 1-2 business days. A Roof Order or EagleView XML on file can bring a Fast Roof set to a single day. The clock starts when the intake is complete, meaning the site survey, equipment list, utility, and AHJ are all in hand. Incomplete intakes are the most common reason a set takes longer.
What does a PV plan set cost?
Pricing depends on system size, mounting type, and complexity — current figures are on the solar plan sets page. A straightforward residential roof mount sits near the low end. Ground mounts, storage, multi-inverter commercial systems, and sets requiring a PE stamp sit higher. Because you pay per plan set, the cost tracks your actual pipeline rather than being committed in advance.
Can an outsourced design team handle my jurisdiction’s code cycle?
That is the question worth asking any partner, because NEC 2017, 2020, 2023, and 2026 are all enforced somewhere in the United States right now, and local amendments modify the state adoption on top of that. Avila Solar draws each set to the cycle the AHJ has actually adopted and names it on the drawings. Tell us the jurisdiction at intake and the set is built to it.
Are there places Avila Solar Drafting will not take projects?
Yes. Avila Solar Drafting does not accept projects in APS or SRP territory in Arizona, the cities of Peoria and Phoenix, or Los Angeles County (LABD) in California. Everywhere else in the United States is fair game, including the rest of California. Commercial projects up to 500 kW run through the standard self-serve process; anything larger starts with a call so scope and schedule can be set before drafting begins.
