Should I open a solar installation business in 2027?

Direct Answer

Probably not — unless you already hold an electrical license, are based in a state with strong net-metering or SREC pricing (NJ, MA, IL, CA-CCA territory), and you can deliver Third-Party-Owned (TPO) lease/PPA financing. The federal 25D residential ITC died December 31, 2025, taking the 30% homeowner cash-purchase incentive with it.

The 48E commercial credit survives only for leases and PPAs through end of 2027. Realistic startup capital: $75,000 to $225,000 for an installing crew, $10,000 to $30,000 for a sales-and-subcontract model. Year-1 owner cash flow: $0 to $90,000 after equipment, NABCEP cert, $25,000 contractor bond, and lead-gen burn.

Breakeven: 14 to 22 months for installer-operators; 6 to 10 months for sales-only models. Solo electricians stacking solar on existing service work win. Standalone cold-start installers in saturated states lose.

The Real Numbers

The 2027 economics changed materially when the One Big Beautiful Bill Act (OBBBA) sunset the 25D residential credit on December 31, 2025. Cash and loan sales now compete without a 30% federal subsidy, and homeowner payback periods stretched from 7-9 years to 11-14 years in most non-net-metering states.

The market shifted to TPO lease/PPA structures, which still claim the 48E commercial credit through December 31, 2027 — so installer revenue now depends on a financing partner (Sunrun, GoodLeap, Sunnova, EverBright) rather than direct homeowner cash.

These figures pull from IBISWorld's Solar Panel Installation industry report, SEIA's 2025 Year in Review (43.2 GW US installed, $50B annual market, 43 GW forecast for 2026), NABCEP's published fee schedule, and California CSLB licensing data. Solar.com and EnergySage both report commercial gross margins of 15-35% versus residential's compressed 22-32% post-25D sunset.

The high-end EBITDA outliers (16.5% to 31.2%) cited in industry models belong to operators who control lead generation in-house, run salaried W-2 closers instead of 1099 dealers, and standardize on a single inverter brand — most new entrants do not.

Who Wins With This Business

• Licensed electricians stacking solar onto existing service businesses. You already carry the C-10 (CA) or equivalent, the truck, the workers' comp policy, and a customer database. Adding PV is a $15,000 incremental investment, not $150,000.
• Operators in SREC-II / SMART / community-solar states. New Jersey ($85-110/SREC-II), Massachusetts (SMART Tier 2), Illinois (Adjustable Block Program), Maryland ($55-70/SREC) still produce 7-9 year homeowner paybacks even without 25D.
• TPO/PPA-focused sales orgs partnered with Sunrun, Sunnova, GoodLeap, EverBright, or Mosaic. These platforms claim the 48E credit through end of 2027 and pay installers a $0.60-$1.40/W EPC fee with predictable funding.
• Commercial and small-utility EPCs (50 kW - 5 MW). The 48E ITC for commercial owners runs through 2032 (with FEOC compliance), making C&I the most reliable growth segment for 2026-2027.
• Battery + EV-charger installers bundling storage. Tesla Powerwall 3, Enphase IQ Battery 5P, and Franklin aPower add $15,000-$28,000 per ticket at 30-40% gross margin, and storage still qualifies for the 25D-replacement 48E credit on leases.
• Operators with in-house D2D canvassing teams. Cutting the $3,500-$5,500 cost-per-acquisition lead-gen burn by 60% is the only path to that 16.5%+ EBITDA.

Who Loses With This Business

• Standalone cash-sale installers in TX, FL, AZ post-NEM-3. California NEM 3.0, Arizona's grandfathered export rate cuts, and Florida's 1:1 net-metering rollback pushed homeowner paybacks past 13 years without 25D.
• Dealer-model 1099 sales orgs without a financing partner. GoodLeap and Sunnova both tightened FICO floors to 680+ in early 2026 and cut dealer fees by 15-25%.
• New entrants with no electrical license relying on a "qualifying party" rental. State boards (CA CSLB, AZ ROC) doubled enforcement actions in 2025 against bond-only operators.
• Operators dependent on door-to-door cold lead-gen in saturated metros (Phoenix, Las Vegas, Houston, Tampa). CPA exceeds $5,500 and close rates have fallen below 4%.
• Anyone underwriting cash-flow assumptions on a federal 30% homeowner credit. That credit is gone. Pro-formas built before mid-2025 are obsolete.
• Installers who took on inverter inventory pre-tariff. Section 201 tariffs on Southeast Asian modules went to 50% in 2025; legacy inventory bought at $0.32/W is competing against $0.21/W direct-import panels.

2027 Market Conditions

• 25D residential credit terminated at midnight December 31, 2025. Cash and loan sales lost 30% federal subsidy.
• 48E commercial credit survives for leases/PPAs through end of 2027; commercial-owned C&I through 2032 with FEOC supply-chain compliance.
• SEIA forecasts 43 GW US install in 2026, flat-to-down in 2027 as residential contracts and C&I expands.
• TPO/lease share projected to grow from 28% (2024) to 55% by end of 2027 per Wood Mackenzie / SEIA Q4 2025 Solar Market Insight.
• Section 201 tariffs at 50% on most Southeast Asian modules; First Solar, Qcells US, and Silfab capacity ramping domestic supply.
• NABCEP-certified installer count grew 11% YoY; licensed installer count contracted 6% as undercapitalized cash-sale shops exited.
• Interest rates above 6.5% continue suppressing loan-financed adoption — TPO sidesteps this by charging $/kWh escalators (2.9-3.5%/yr) rather than monthly loan payments.
• State-level wins: NJ SREC-II, IL ABP, MA SMART, MD SREC, NY NY-Sun all still produce sub-10-year residential paybacks.
• Battery attach rates hit 27% nationally in 2026 (vs 12% in 2023) — storage now drives ticket size, not panels.

The 90-Day Decision Tree

1. Day 1-7: Verify your state license path. If you do not hold an electrical contractor license (CA C-10/C-46, FL EC, TX TDLR Master Electrician), price the cost of either getting one (3-4 years apprenticeship + exam) or partnering with a Responsible Managing Employee (RME). No license = no business.
2. Day 8-14: Pick a financing partner BEFORE you pick a panel brand. Apply to Sunrun, Sunnova, GoodLeap, EverBright, or Mosaic as a dealer/installer. Their underwriting takes 4-8 weeks. Without a TPO partner you cannot offer the only remaining federal incentive.
3. Day 15-30: Run your state-specific payback math. Plug current utility rates, net-metering rules, and SREC prices into OpenSolar or Aurora for three sample homes. If payback exceeds 11 years without state incentive, pick a different state or pivot to C&I.
4. Day 31-45: Get NABCEP-certified or hire someone who is. Pay the $500 exam fee + $1,500 SEI training. Distributors (CED Greentech, Krannich, Soligent) extend better credit terms to NABCEP shops.
5. Day 46-60: Lock distributor accounts and a single inverter standard. Standardize on Enphase IQ8 (residential) OR Tesla Powerwall 3 integrated (battery-first). Mixed-brand fleets destroy service margins.
6. Day 61-75: Build a Year-1 pro-forma with brutal assumptions. 30 jobs, $28,000 average ticket, 24% gross margin, $80,000 lead-gen burn, $35,000 in trucks/tools. If you cannot survive at those numbers, do not start.
7. Day 76-90: First 3 paid installs OR walk. Use friends-and-family or a roofing-contractor referral partnership. If you cannot close 3 jobs in 90 days, the market is telling you something.

Alternative Plays

• Battery-only retrofit installer. Powerwall 3 + Franklin aPower retrofits average $22,000 ticket at 35% gross margin, qualify for the 48E credit via lease structure, and require no roof work (lower insurance, faster jobs, fewer callbacks).
• Commercial-only EPC (50 kW - 1 MW). 48E credit runs through 2032 for commercial owners. Tickets are $150,000-$2.5M; gross margins 12-18%; sales cycle 6-12 months but recurring O&M revenue.
• Solar O&M and service contractor. 3.5 million US residential solar systems are now out of warranty or post-bankruptcy (SunPower, ADT Solar, Sunworks). Inverter replacements, panel cleaning, and monitoring contracts pay $400-$1,200/yr per system with 45-60% gross margin.
• Sales-only TPO dealer. $10,000-$30,000 startup, subcontract installs to a licensed shop, earn $0.60-$1.10/W dealer fee from Sunrun/Sunnova/EverBright. Lower margin but no truck, no bond, no workers' comp.
• Community solar subscriber acquisition. Earn $80-$200 per signed subscriber in IL, NY, MN, MA, CO community solar markets. No installation at all — pure marketing arbitrage.
• EV charger installer (Level 2 residential + commercial DCFC). Same electrical license, 48C manufacturing credit drives OEM rebates, $1,800-$4,500 residential tickets, 35-45% gross margin.

FAQ

Is the 30% federal solar tax credit really gone for homeowners in 2027?

Yes — the 25D Residential Clean Energy Credit terminated at midnight December 31, 2025 under the One Big Beautiful Bill Act. Cash and loan-financed residential installs no longer qualify for any federal credit. The only path for homeowners to indirectly benefit from a federal credit is a lease or PPA, where the third-party owner claims the 48E credit through end of 2027.

State credits (NY, MA, NJ, MD, IL) still apply on top, but the headline 30% federal subsidy is over for direct-purchase residential.

What's a realistic Year-1 revenue for a new solar installer?

For a licensed installer-operator with one 2-3 person crew, $420,000 to $1.1 million across 15-30 residential jobs at an $24,000-$38,000 average ticket is realistic. Sales-and-subcontract dealer models hit $180,000-$480,000. EBITDA in Year 1 is typically negative or breakeven after lead-gen, insurance, bonds, and inventory.

Year-3 EBITDA for surviving operators lands at 8-15%, with elite operators (in-house leads, single-brand stack) reaching 16-25%.

Do I need to be a licensed electrician to start a solar installation business?

In most states, yes — directly or via a "qualifying party." California requires a C-46 (Solar) or C-10 (Electrical) license with 4 years journey-level experience. Florida requires an EC (Electrical Contractor) license. Texas requires a Master Electrician or licensed solar contractor.

NABCEP PV Installation Professional certification is industry-standard but not a legal substitute for state licensing. Operating without a license triggers stop-work orders, $5,000-$25,000 fines, and disqualifies you from utility interconnection.

Should I focus on residential or commercial solar in 2027?

Commercial — if you can wait 6-12 months per sale. The 48E commercial ITC runs through 2032, average tickets are $150,000-$2.5M, and gross margins of 12-18% beat residential's compressed 22-32% (after $3,500-$5,500 CPA leads). Residential makes sense only in SREC-II states (NJ, MA, IL, MD, NY-Sun) or via a TPO partnership with Sunrun/Sunnova where the financing partner carries the credit risk.

Battery + storage retrofits remain the highest-margin residential play.

How much should I budget for lead generation in Year 1?

Budget $30,000-$80,000 minimum. Residential solar CPA (cost per acquisition) ranges $3,500 in lightly-competed metros to $5,500+ in Phoenix, Las Vegas, Houston, Tampa. Close rates on purchased leads run 4-9%, meaning each closed deal absorbs $40,000-$130,000 of marketing cost spread across the funnel.

The only paths under this are: in-house D2D canvassing teams (which cost $4,000-$8,000/month per canvasser), roofing/HVAC referral partnerships (typically $500-$1,500 referral fee), or a TPO partner's house leads.

Bottom Line

Open this business only if (a) you already hold an electrical contractor license, (b) you operate in NJ, MA, IL, MD, or NY-Sun territory, AND (c) you have a signed dealer agreement with Sunrun, Sunnova, GoodLeap, EverBright, or Mosaic. All three conditions, not two. The death of the 25D residential credit on December 31, 2025 fundamentally re-priced cash-sale solar, and survivors are either licensed electricians stacking solar onto existing service businesses, commercial EPCs riding the 48E credit through 2032, or pure sales orgs feeding TPO platforms.

Standalone cash-sale residential installers in TX, FL, AZ, and post-NEM-3 CA are the losers of this cycle. If you cannot check all three boxes, run the alternative plays — battery-only retrofits, commercial EPC, O&M service, or EV charger installation — which carry better margins, lower capital intensity, and longer-duration federal incentives.

Reasonable owner cash flow in Year 1: $0 to $90,000. Reasonable Year-3 EBITDA: 8-15%. Breakeven: 14-22 months.
