Solar sits at the crossroads of three trades, so becoming a solar installer means getting the licenses that cover both the electrical work and the roof work, then earning the NABCEP credential the industry treats as gold standard. In most states the wiring and interconnection require an electrician's license, and the roof penetrations and racking can require a roofing or general contractor license on top, so a full rooftop install often needs more than one license. On top of the licensing, 2026 is an honest inflection point for the trade after the federal residential tax credit ended, so it is worth understanding the market before you commit. Your exact license stack routes to the Contractor License Checker.
What the work actually is
Solar installation combines electrical, structural, and increasingly battery work:
- Electrical. Wiring the array, the inverter, and the interconnection to the panel and grid. This is licensed electrician's work in most states, under NEC Article 690.
- Structural. Mounting racking and penetrating the roof without causing leaks or failures, which overlaps with roofing.
- Energy storage. Battery systems, a fast-growing and higher-margin add-on that carries its own credential.
Because it spans trades, solar attracts electricians adding a specialty, roofers moving up, and dedicated solar crews, and the licensing has to match whichever parts of the job you self-perform.
The licensing reality: usually more than one license
This is where new solar businesses get caught. A full rooftop install can legally require:
- An electrician's or electrical contractor license for the wiring and interconnection, in most states.
- A roofing or general contractor license for the structural attachment and roof penetrations, in several states.
- A dedicated solar contractor classification, which some states have created specifically.
In a good number of states, a solar company needs both an electrical contractor license and a roofing or general contractor license to legally do a complete rooftop system. A handful of states also recognize NABCEP certification as a pathway to install PV in specific situations. Because the combination varies so much, run your exact state through the Contractor License Checker before you scope the business.
NABCEP: the credential the industry looks for
The North American Board of Certified Energy Practitioners (NABCEP) is the industry's gold-standard credentialing body, and its credentials open doors with utilities, inspectors, and commercial specifiers:
- NABCEP PV Associate, the entry-level knowledge assessment, with no experience requirement.
- NABCEP PV Installation Professional (PVIP), the flagship credential, requiring documented field hours in decision-making roles plus an exam. This is the one utilities and commercial buyers recognize.
- NABCEP Energy Storage Installation Professional (ESIP), for battery work, requiring advanced storage training, OSHA 30, and demonstrated storage project experience.
Training routes include Solar Energy International, MREA, HeatSpring, and community colleges. NABCEP is usually not the legal license, but it is the credibility marker that wins work.
The honest market reality in 2026
A solar guide that ignored the tax-credit change would be lying by omission, so here it is straight. The 30% federal residential solar tax credit (Section 25D) was terminated by the law signed on July 4, 2025. To qualify, a residential system had to be installed and operational by December 31, 2025. There is no phase-down: signing a contract, paying a deposit, or pulling a permit does not count, only completed installation by that date. That means the cash and financed residential market that boomed before the deadline is materially smaller in 2026.
What did not end:
- Commercial and utility-scale credits (Sections 48E and 45Y) were not eliminated, though they carry new restrictions and their own timing windows (commence-construction and placed-in-service deadlines).
- Third-party ownership (leases and power purchase agreements) remains permissible, which keeps part of the residential market alive through a different structure.
The honest takeaway: residential owner-purchased solar demand is contracting in 2026 compared with the pre-deadline surge, while commercial, utility-scale, and third-party-ownership work remains viable. If you are entering the trade now, aim at the segments that still have tailwind, and verify the current tax rules at irs.gov because tax law keeps moving.
The certs that unlock the better-paid work
- NABCEP PV Associate to start, PVIP to compete, the credibility markers for the whole trade.
- NABCEP ESIP for battery and storage work, the higher-margin growth area.
- An electrician's license if you self-perform the electrical, which most states require.
- OSHA 10 or OSHA 30, and fall protection training, because this is rooftop work.
The startup reality
Setting up a solar business means the standard kit plus the license stack this trade demands: potentially an electrical contractor license and a roofing or general contractor license, forming your business, general liability, commercial auto, and the racking, conduit, and tools for a crew. The licensing is the real cost and complexity here, more than the tools. Build your numbers from real quotes, and scope which parts of the install you self-perform versus subcontract.

Common questions
What license do I need to install solar panels?
In most states you need an electrician's or electrical contractor license for the wiring and interconnection, and in several states a roofing or general contractor license as well for the roof work. A full rooftop install often needs more than one license. Some states have a dedicated solar contractor classification, and a few recognize NABCEP certification as a pathway in specific cases. Because the required combination varies so widely, confirm your exact state's license stack in the Contractor License Checker before you take a job.
Is NABCEP certification required to install solar?
Usually not legally, but it is the credential the industry looks for, so in practice it is close to essential for competitive work. NABCEP is not typically the legal license (that is your state's electrical and contractor licensing), but utilities, inspectors, and commercial buyers recognize the PVIP credential as proof you know the work. Start with the PV Associate, then earn the PVIP once you have documented field hours. A few states do recognize NABCEP as a pathway in specific situations, which routes to the Contractor License Checker.
Did the solar tax credit really go away?
The 30% federal residential solar tax credit (Section 25D) was terminated. Residential systems had to be installed and operational by December 31, 2025 to qualify, with no phase-down. Signing a contract or pulling a permit did not count, only completed installation by that date. Commercial and utility-scale credits (48E and 45Y) survived with new restrictions and their own deadlines, and third-party ownership like leases and PPAs is still allowed. This is enacted federal tax law as of 2026, so verify the current position at irs.gov before advising any customer.
Is solar still a good trade to get into in 2026?
It depends on which segment you target. Owner-purchased residential demand is contracting after the tax credit ended, but commercial, utility-scale, and third-party-ownership work remains viable. Entering the trade now means aiming at the segments that still have tailwind rather than the pre-deadline residential surge that has passed. Battery and storage work (NABCEP ESIP) is a growth area within it. Scope your market honestly, and for real local demand and pricing, use the pricing tools and Working in Your State.
The honest bit
- The license combination for solar (electrical, roofing or general contractor, or a dedicated solar classification) varies widely by state, and a full install often needs more than one. Do not assume from a neighboring state. Get your specifics from the Contractor License Checker.
- We do not publish wage or rate figures. What a solar installer earns swings by state, by residential versus commercial, and by whether you carry NABCEP and storage credentials. For real local numbers, use the pricing tools and Working in Your State.
- The tax-credit facts here (the 25D termination and December 31, 2025 residential deadline, the 48E and 45Y commercial windows, and the status of third-party ownership) reflect enacted federal law as of 2026 and are subject to further change. Verify the current position at irs.gov before you rely on them or advise a customer.
- This is general guidance on becoming a solar installer, not legal, licensing, or tax advice. Given the multi-license requirement and the shifting tax landscape, confirm both before you commit.
