First find out which parts of a PV install your state treats as electrical work and who must do or supervise it, because that decides whether your first hire is an installer, an apprentice or a licensed electrician. Treat the NABCEP PV Associate as proof of solar knowledge, not a license. Before the first roof, train the hire on fall protection and on circuits that stay live in daylight, buy their gear, confirm workers' comp and set pay from local wage data.
Your state's licensing rules decide what your first hire may legally do on a solar job, so get those answers before you write the job ad. A rooftop install mixes roof work (attachments, flashing, racking, setting modules), PV wiring (module connections, wire management, the runs to the inverter) and the service connection (inverter output, disconnects, the tie-in to the home's panel, batteries). States draw their licensing lines between those differently.
Ask your state's electrical licensing board, and its contractor board if that's a separate agency:
Get the answers in writing from the board, because the rules differ by state and change. Ask the building departments where you pull permits too; a city or county can add registration rules of its own.
Don't let a certification stand in for a license. NABCEP says its certifications are voluntary, are not a license issued by a government agency, do not authorize anyone to practice and do not replace state licensing requirements 1. If the electrical work needs a license you don't hold, hire a licensed electrician or subcontract that portion to a licensed electrical contractor where your state allows it. Licensing for the company itself is covered in how to start a solar installation business.
Each role changes what you screen for, what you pay and how much of your day goes to supervision.
| Role | Takes off your plate | Screen for |
|---|---|---|
| Installer | Staging modules, attachments and flashing, racking, setting modules | Comfort at height, careful hands, reliability, a driving record your insurer accepts |
| Licensed electrician | PV wiring, inverters, the service tie-in, batteries | A current license you've checked with your state board, PV or battery experience |
| Apprentice | Roof work first, supervised electrical work later | Aptitude, willingness to study, eligibility for your state's apprentice registration |
| Lead installer | Runs the roof while you sell, design and chase permits | Installs they led, references, ideally a NABCEP PV Installation Professional certification |
If you're the licensed electrician on every job, an installer who handles attachments, racking and modules frees you for wiring, inspections and sales. If your state reserves PV electrical work for licensed electricians and you want to grow your own, ask your electrical board how an apprentice's hours count toward a license and whether they must be earned in a registered apprenticeship program. Then ask your state apprenticeship agency or a community college electrical program whether there's a registered program you can join as an employer.
For someone new to solar, the NABCEP PV Associate is a sensible credential to ask for or to pay for. NABCEP aims it at people new to solar or early in a solar career: candidates qualify through a course with a NABCEP registered training provider or through documented PV work experience, then pass an exam, and must be 18 or older 2. NABCEP certifications and credentials are valid for three years, and holders apply to renew during the third year 3, so put the date in the hire's file. The NABCEP certification entry covers the wider family of credentials.
Treat it as proof of study, not of skill; the paid working day below tests the rest. If a promising candidate doesn't have it yet, offer to pay for the course and exam once they've proved themselves on your crew.
The next step is the PV Installation Professional (PVIP) certification. NABCEP requires 10 hours of OSHA construction outreach training, at least 58 hours of advanced PV training (40 of them from an accredited institution), documented installations and an exam 1. Installations count only if they are complete, permitted and passed final inspection, each rated at least 1 kW DC, and only where the applicant held a decision-making role such as lead installer, system designer, project manager or foreman 1.
So your hire can't log a qualifying install until you let them lead one. Write down what it takes to get there, and keep a log for every job: address, system size, permit number, final inspection date and who led. A credential your installer can see coming is a reason to stay.
Fall protection is the rule OSHA cites most: its general requirements (29 CFR 1926.501) topped OSHA's list of most frequently cited standards in fiscal years 2024 and 2025 4.
In residential construction, each employee working 6 feet or more above a lower level must be protected by a guardrail system, a safety net system or a personal fall arrest system, unless another provision of the rule allows an alternative 5. A written fall protection plan is allowed only if you can show those systems are infeasible or create a greater hazard 5. On a pitched roof the practical answer is usually a personal fall arrest system: harness, lanyard or rope grab, lifeline and roof anchor. The fall protection entry explains each system.
Each employee who might be exposed to fall hazards must be trained by a competent person, covering the fall hazards in the work area and how to erect, maintain, disassemble and inspect the fall protection systems to be used 6. Train on your own anchors and harnesses, even if the hire has installed solar for years. Certify the training in writing with the employee's name, the training dates and the signature of the trainer or the employer, and retrain anyone you have reason to believe lacks the understanding or skill the training requires 6, for example after a switch to new anchors, a near miss or catching someone unhooked.
Protective equipment used to comply with OSHA's construction standards must be provided at no cost to employees, apart from narrow exceptions such as non-specialty safety-toe boots and prescription safety glasses that employees may wear off the job, and everyday clothing and weather gear 7. The harness, lifeline and anchors are on you. Buy a harness that fits the hire, not you.
Modules produce electricity whenever light hits them, and opening a disconnect doesn't stop the modules upstream of it from producing voltage. Train for that before the hire touches a connector:
Teach it on your own equipment (you or your licensed electrician), add a formal electrical safety course if you aren't confident teaching it, and keep a training record like the fall protection one. Whatever the hire's experience, keep them off tasks your state reserves for licensed electricians, and teach to the edition of the electrical code your inspectors enforce.
OSHA says more than 70 percent of heat-related deaths happen during a worker's first week, and almost half on the first day on the job or the first day back after an extended absence 8. Its guidance for new and returning workers is to start with 20% of the usual time in the heat on day one and add no more than 20% on each day after 8. On a solar crew that schedule is easy to keep: put the new hire on the roof in the cooler morning, then on staging, prep and training on the ground in the afternoon. Build water, rest and shade into the schedule.
Federal child labor rules generally prohibit anyone under 18 from roofing occupations and from other work on or about a roof, including from ladders and scaffolds at or near it, with a narrow exception for 16- and 17-year-olds in a bona fide apprenticeship or student-learner program 9. Before you hire a minor for any job near a roof, ask the Department of Labor's Wage and Hour Division how that applies to your work, and check your state's child labor law. The PV Associate also requires candidates to be 18 or older 2.
A 1099 doesn't make your installer a subcontractor; how you work together decides it. Answer these honestly:
If most answers point to you, plan on an employee, and have a CPA or employment lawyer review any contractor arrangement before you rely on it: the IRS and the states apply their own tests, and the facts decide. The independent contractor entry covers the basics. For a real subcontractor, collect certificates for their workers' comp and liability coverage, confirm any license your state requires for their tasks, and put in writing who carries the workmanship warranty, who repairs leaks from their attachments and what fall protection you expect.
Workers' compensation is set by state law and the rules differ from state to state, so confirm yours with your state's workers' comp agency or a licensed agent before day one. Describe the whole job (roof attachments, electrical work, battery installs) and ask how the carrier classifies rooftop solar work, since that drives the premium. The workers' compensation insurance entry explains the basics.
For pay, start with the national picture, then go local. BLS reports May 2025 median pay of $53,140 a year for solar photovoltaic installers, with the lowest 10 percent earning less than $41,600 and the highest 10 percent more than $79,970, and projects employment in the occupation to grow 37 percent from 2025 to 2035, much faster than average 10. Pay varies by area, so check the BLS state wage estimates for solar photovoltaic installers, and for electricians if your hire will do electrical work 11. Then settle these in writing:
Solar jobs are priced and compared per watt, so convert the hire's cost into the same unit.
Example: You pay a new installer $25 an hour for a 40-hour week, so $1,000 in wages. Suppose payroll taxes, workers' comp and gear add $300 a week (made-up numbers; get real ones from your payroll provider and your agent). That's $1,300 a week. If drive time, supply runs and weather leave 30 hours a week on actual installs, each install hour costs about $43.33. On an 8 kW (8,000-watt) job where the new hire works 20 hours, their labor costs about $867, or roughly $0.11 per watt, before your own time, overhead and profit.
Run your real numbers through how to set your labor rate, and see how to price solar installations for where labor sits among the other costs.
Bring your top candidate along for a paid day of real work, confirm with your agent that your coverage extends to a working interview, and tell the candidate what you'll watch:
| Watch for | What good looks like |
|---|---|
| Fall protection | Inspects the harness, clips in before reaching the edge, keeps the lifeline off finished modules |
| Hoisting | Sends modules up by hoist or with a ground partner, never climbs with one |
| Attachments | Finds rafters, follows the plan set's spacing, flashes each penetration as the manufacturer specifies |
| Racking and modules | Torques to the manufacturer's values, never steps on a module |
| Wire management | Keeps conductors off the roof surface and away from sharp edges |
| Electrical habits | Tests before touch, knows what stays live, never unplugs under load |
| Documentation | Photographs each flashed attachment before it's covered, records serial numbers |
Questions that separate field experience from a good interview:
Keep photos, serial numbers, permit numbers and the install log where the whole crew can find them, whether that's a shared folder, a group chat or chat-first field service software such as Redline. The same record answers the inspector, backs up a warranty claim and supports a future NABCEP application.
You can set up piece pay, but it doesn't switch off overtime. Covered non-exempt employees must be paid at least one and one-half times their regular rate for hours over 40 in a workweek 12. Before you set it up, ask your payroll provider or your state labor department how the regular rate is figured for piece pay and how minimum wage applies, and track hours either way.
Only once your state says so. Ask your licensing board whether it accepts their license or what they need to get licensed where you work, and keep them off licensed tasks until you have the answer in writing. A NABCEP credential is different: it isn't a government license 1, so a move doesn't change it, but check that it's current, because NABCEP certifications and credentials are valid for three years 3.
Hire for the gap you have. A roofer arrives with habits that matter on day one, such as working tied off and flashing penetrations so they don't leak, but has to learn PV wiring and electrical safety. An electrician brings the license and code knowledge but may never have worked on a roof, so plan more time for fall protection and attachments. If you already do the electrical work yourself, a roofer usually frees up more of your week.
Rules and figures change, and many requirements vary by state and city. Check the current version of each source and your local authority before acting, and talk to a licensed professional about your specific situation.
