Enphase Energy (ENPH) faces a pivotal transition as the residential solar industry adapts to life without the 30% investment tax credit.
The company posted Q3 revenue of $410 million, its highest level in two years, but management is bracing for a sharp Q1 2026 decline to approximately $250 million as homeowners rush to capture the expiring tax benefit before year-end.
CEO Badri Kothandaraman isn’t backing down.
- The company shipped a record 195 megawatt-hours of batteries in Q3 while maintaining a 49% gross margin despite tariff headwinds.
- Fourth-generation IQ Battery 10C adoption is accelerating, capturing 40% of U.S. battery shipments in just its first full quarter.
- The company is also entering the $400 million commercial microinverter market with its gallium nitride-powered IQ9 platform.
Despite near-term uncertainty, Enphase stock trades at $36, potentially offering upside for investors who recognize the company’s technology leadership and multiple paths to recovery.

What the Model Says for Enphase Energy Stock
We analyzed Enphase’s transformation from a pure-play microinverter company into a complete energy management platform serving both residential and emerging commercial markets.
The company operates in a brutal environment.
- The expiration of the 25D tax credit eliminates 30% of the upfront value for cash and loan customers, the industry’s traditional core.
- Europe remains challenged as feed-in tariffs compress and net metering programs phase out.
- Tariffs on Chinese cell packs add roughly 5 percentage points of gross margin pressure.
Yet Enphase has multiple levers.
- The fourth-generation battery delivers 30% higher energy density while reducing backup installation costs.
- Partnerships with utilities like Essent in the Netherlands unlock a $2 billion retrofit opportunity across 475,000 existing solar installations.
- The IQ9 commercial microinverter opens access to 480-volt three-phase systems previously dominated by Chinese equipment.
- Prepaid lease structures with third-party owners could revive loan-like economics for homeowners.
Using a forecast of -0.1% annual revenue decline and 9.3% operating margins, our model projects the stock will rise to $55 within 1.9 years. This assumes a 14.5x price-to-earnings multiple.
That represents compression from Enphase’s historical P/E averages of 16.3x (one year) and 41.6x (five years). The lower multiple reflects execution risks around the tax credit cliff, tariff pressures, and uncertainty about new financing structures gaining traction.
The real value lies in navigating the 2026 trough while capturing share gains in batteries, commercial markets, and international retrofit opportunities.

Our Valuation Assumptions
TIKR’s Valuation Model lets you plug in your own assumptions for a company’s revenue growth, operating margins, and P/E multiple, and calculates the stock’s expected returns.
Here’s what we used for ENPH stock:
1. Revenue Growth: -0.1%
Enphase faces a perfect storm. Management expects Q1 of 2026 revenue to drop to $250 million, down from $410 million in Q3 2025, as the 25D credit expires and channel inventory normalizes.
The company anticipates this represents the cycle trough.
Three external factors could drive recovery: rising power prices (up 5% this winter as AI infrastructure strains grids), declining interest rates that improve financing affordability, and new prepaid lease products that capture the 48E commercial tax credit while offering homeowners ownership options after five years.
Enphase-specific drivers include fourth-generation battery momentum, the December launch of IQ9 commercial microinverters, battery retrofit partnerships in the Netherlands, bidirectional EV chargers enabling vehicle-to-home backup, and fifth-generation batteries with 50% higher energy density, launching mid-2026.
2. Operating margins: 9.3%
Enphase delivered 30% operating income in Q3 on 49% gross margins. That performance included higher shipments of safe-harbor microinverters and approximately $42.5 million in IRA manufacturing credits.
The company expects gross margins around 43.5% in Q4 as product mix normalizes and tariff impacts persist. Management projects 5 percentage points of reciprocal tariff pressure until non-China cell pack sources ramp in early 2026 and fifth-generation battery costs decline significantly.
Operating expenses run approximately $80 million per quarter. Management will trim spending to protect profitability while preserving investments in innovation and customer service quality that drive 77% Net Promoter Scores.
3. Exit P/E Multiple: 14.5x
The market values Enphase at 17.7x trailing earnings. We assume the P/E will compress to 14.5x over our forecast period.
Near-term headwinds justify caution. The expiration of the tax credit creates genuine demand uncertainty. Europe remains challenged with reduced feed-in tariffs and competitive pressure. Tariffs weigh on battery margins until the supply chain is fully diversified.
As financing innovation takes hold and Enphase demonstrates execution on batteries, commercial expansion, and cost reduction, the company should command a reasonable premium for its technology leadership, domestic manufacturing, and exposure to the electrification megatrend.

What Happens If Things Go Better or Worse?
The residential solar industry is notoriously cyclical, driven by policy changes and financing availability. Here’s how Enphase stock might perform under different scenarios through December 2029:
- Low Case: If revenue growth stays flat at 2.1% and net income margins compress to 52%, investors still see a 76% total return (15.6% annually).
- Mid Case: With 2.2% growth and 59.8% margins, we expect a total return of 134% (24.3% annually).
- High Case: If recovery accelerates to 2.4% growth and margins expand to 67.9%, total returns could reach 204% (32.8% annually).

The range reflects execution on prepaid lease adoption, battery market share gains, commercial microinverter traction, and success in navigating the post-tax credit environment.
In the low case, financing innovation disappoints and competition intensifies.
In the high case, new structures revive demand faster than expected while cost reductions drive margin expansion ahead of schedule.
