E/P over time
E/P = trailing-12-month diluted EPS / price at quarter end. E/P is the inverse of P/E and stays defined when earnings are negative.
Today's P/E sits at the 44 percentile of its own 16-quarter history (min 25.1, median 50.0, max 255.9; quarters with earnings only).

Memo
Enphase Energy, Inc. (ENPH). Latest full fiscal year: 2025; data up to 2026-09-30.
Figures computed from the financial statements: revenue 1.5 bn USD in 2025; YoY growth 10.7%; net margin 7.5%; ROE 8.1%; net debt/EBITDA 1.5x.
The estimated value range is 10.19–24.13 USD per share (median of 3 methods, agreement: medium); assumptions are illustrative. Against the central value of 15.10 USD, the price of 31.55 USD leaves a potential of -52.1% (value / price − 1) and a margin of safety of -108.9% (1 − price / value). The range is the median of the methods' low, central and high values, not a probability interval.
olivLaw score 43/100, methodological classification: unattractive profile (score, margin of safety and method agreement together; not a judgement of the right price). Not investment advice.
Text generated deterministically from the figures shown; no language model. Not investment advice.

What contradicts it
- Gross margin: 45.8%
- Revenue CAGR 3Y: -14.2%
- Net debt / EBITDA: 1.5x

In brief
Enphase Energy designs and sells microinverters and storage systems for residential and commercial solar, managed on a shared software platform. The company reported revenue of 291.9 million USD in the second quarter of 2026 3, and its strategy is increasingly directed to storage, EV charging and the infrastructure for data centers 23.
SWOT
Strengths
- The company holds a leading position in microinverters and a large installed base, supported by its own software platform 1.
- Its US manufacturing footprint and substantial cash balance give flexibility against tariffs and policy changes 13.
- The product range has expanded from solar into storage, EV charging and energy management, which raises value per customer 1.
Weaknesses
- Revenue depends heavily on one customer and on the US market, making results sensitive to changes there 1.
- Some critical components, including LFP battery cells, come from outside the US from a small number of suppliers 1.
- Quarterly revenue is volatile because of safe harbor agreements and revenue recognition, and GAAP margin can be affected by one-off items 23.
Opportunities
Risks
- Removal of subsidieshigh
Reduction or elimination of tax credits and NEM programmes could lower demand and prices for solar systems 1.
- Compliance with domestic content and FEOC ruleshigh
If products do not meet domestic content thresholds or FEOC rules, they could lose eligibility for tax credits 12.
- Tariffs and supply chainmedium
Critical components still come from outside the US, and escalating tariffs could raise costs and reduce margins 13.
- Weak demand in Europemedium
The business environment in Europe remains difficult, and insolvencies in the distribution channel could affect revenue and credit loss allowances 1.
- Customer concentrationmedium
One customer accounted for a large share of revenue, and losing it could affect results 1.
Investment thesis
What would need to be true (bull case)
- If the TPO model and storage develop, the company could benefit from a larger sales channel and steadier demand 12.
- If data center projects advance, IQ SST could open a new, higher-value revenue source 23.
- Its leading position in microinverters and broad installed base could support market share over the medium term 1.
What would break the thesis

Products, market & competition

The business
Enphase Energy, Inc. is a global energy technology company, founded in March 2006, that designs, develops, manufactures and sells home energy solutions covering solar generation, storage, load control and communications on one intelligent platform 1. The company says it has shipped approximately 86.4 million microinverters and that more than 5.1 million Enphase systems were deployed in over 160 countries, as of 31 December 2025 1. Sales go mainly through solar distributors, who resell to installers, and directly to large installers, OEMs and strategic partners, including third-party finance providers 1.
In fiscal 2025, one customer accounted for about 39% of net revenues, and the United States market represented 81% of net revenues 1. This concentration makes changes in US support policy and in the contracts with a large customer significant for the company's results 1.
Segments
Microinverters and IQ systems
IQ Microinverters convert energy at the individual module level and form the core of the company's products, including the IQ8 and IQ9N models for residential and commercial use 12. In June 2026 the company launched the IQ9N for residential use in the United States and key European markets 3.
Energy storage (IQ Battery)
IQ Batteries are built on the Ensemble OS software and are shipped in the United States and several European countries 1. In the second quarter of 2026, 113.8 MWh of IQ Batteries were shipped, and the upcoming IQ Battery G5 is presented as offering higher energy density and lower cost 3.
Market context
The residential and commercial solar market is highly competitive, with demand still fragile in some regions, especially Europe, where the business environment remains difficult 12. Policy changes in the US, including OBBBA, change tax conditions for solar and storage systems, and the company says the shift to the TPO model could become an important growth channel 12.
The sector depends on subsidies and policies such as NEM, and a reduction of these could lower demand 1. Pressure from tariffs and price competition remains an important factor for margins 23.
Trends
- Expiry of the residential tax creditheadwind
The Section 25D credit expired on 31 December 2025, and leased projects face placed-in-service conditions through the end of 2027 12. If demand does not shift to the TPO model, the effect could be negative.
- TPO model and safe harbor agreementsmixed
The company has signed safe harbor agreements with TPO finance providers, which it sees as an important growth channel but which can create variability in revenue recognition 123. The effect is mixed.
- Domestic content and FEOC rulesheadwind
OBBBA rules impose stricter domestic content thresholds and FEOC restrictions, and failure to comply could reduce access to credits 12. US production and the supply chain are therefore sensitive to these rules.
- Demand from AI data centerstailwind
Development of IQ SST and customer engagement in the data center space could open a new revenue line if projects materialise 23. The effect is positive but not yet commercially proven.
Competitive position
Competition includes central and string inverter makers, storage system manufacturers and EV charger providers 1. According to the sources, larger competitors have greater financial and distribution resources, and some offer products at aggressive prices 1.
The company's differentiation rests on its microinverter architecture and software platform, but price and tariff pressure remains high 13. The company states that its redundant design reduces the risk of a single point of failure 1.
