It’s a rough Monday for many solar investors. SolarEdge Technologies (NASDAQ:SEDG) stock is down 7% today, sliding from $48.75 to $45 and change, while Enphase Energy (NASDAQ:ENPH) stock is off 4%, dropping from $34.92 to around $33.50. Broader tariff concerns are weighing on growth and clean energy names across the board, and these two solar inverter leaders aren’t being spared.
The selling pressure isn’t coming out of nowhere. Both companies face shared headwinds: reciprocal tariff impacts running at roughly 5 percentage points of margin pressure, softening European demand, and a fiercely competitive solar inverter market. That combination is enough to rattle even the most patient investors on a risk-off Monday.
The Invesco Solar ETF (NYSEARCA:TAN) is also sliding today, down 2% as of this afternoon, confirming that today’s move is sector-wide. That context matters when sizing up whether to treat today’s drop as noise or something more structural.
SolarEdge’s Recovery Story Hits a Speed Bump
SolarEdge has come a long way. SEDG stock is still up 57% year-to-date and up 208% over the past year, a remarkable rebound from a period when the company posted a net loss of $1.8 billion in fiscal 2024. Today’s 7% drop stings, but some profit-taking on a down sector day isn’t surprising.
The deeper concern is valuation. SolarEdge Technologies carries a forward P/E ratio of 797x, leaving little room for execution stumbles. The company is still posting significant GAAP losses, with a full-year 2025 net loss of $405.45 million, even as operating cash flow turned positive at $104.26 million for the year.
Competition is the other pressure point. SolarEdge Technologies recently launched the Nexis modular home storage system, aimed at taking on Enphase and SMA Solar in the residential energy storage market. CEO Shuki Nir is also pivoting toward AI data center power applications, which could open new revenue streams. These are real catalysts, but they’re early-stage bets in a market demanding near-term profitability.
Analysts expect SolarEdge to report Q1 2026 EPS of -$0.24 and revenue of $303.97 million, which would represent 38.49% revenue growth year-over-year. TD Cowen raised its price target on SEDG to $43 from $38 following Q4 results, though the stock has since traded well above that level. Today’s pullback brings it back toward a range where the analyst community is more comfortable.
Just a few weeks ago, SolarEdge Technologies was the talk of the solar sector for very different reasons. The stock had rocketed 14% in a single session, lifting the broader solar group with it. Today’s reversal is a reminder of how quickly sentiment can shift in high-beta clean energy names.
Enphase Energy: Longer-Term Pressure Compounds Today’s Drop
Enphase Energy’s situation is more nuanced. Unlike SolarEdge, Enphase Energy hasn’t enjoyed a strong year. ENPH stock is down 42% over the past year, so today’s 4% decline adds to a painful stretch for shareholders who’ve been watching revenue contract and margins compress.
The numbers tell a challenging story. Enphase Energy’s Q4 2025 revenue came in at $343.32 million, down 10.3% year-over-year, while free cash flow dropped 76.24% year-over-year to $37.84 million. Tariffs are biting into gross margins by roughly 5.1 percentage points, and European revenue declined approximately 29% quarter-over-quarter in Q4.
Management’s long-term target of $1.6 billion in revenue by 2028 implies modest annual growth from current levels, which doesn’t inspire confidence in a stock already priced for a recovery. Ongoing lawsuits are adding uncertainty that’s keeping institutional buyers cautious. Enphase Energy did recently launch IQ Energy Management, targeting the growing Australian and New Zealand markets, which could provide a meaningful geographic diversification lift if execution follows through.
What to Watch
For SolarEdge Technologies, the next major catalyst is the Q1 2026 earnings report. Watch for whether the company’s revenue guidance of $290 million to $320 million and a non-GAAP gross margin target of 20% to 24% hold up against tariff headwinds.
For Enphase Energy, the Q1 2026 guidance range of $270 million to $300 million in revenue will be the key test of whether the revenue decline is stabilizing.
SEDG and ENPH stocks are high-beta names that can be sensitive to policy and macro shifts. If you’re already in either position, today’s move is worth monitoring into the close to see whether the selling accelerates or stabilizes. Neither stock is cheap enough to be a clear defensive buy right now, but both underlying technology businesses have real product momentum that shouldn’t be dismissed.
