Solar names are surging in early trading on Tuesday as an AI data center power narrative grips the sector. Enphase Energy (NASDAQ:ENPH | ENPH Price Prediction) stock is up 8% to $52.31, while SolarEdge Technologies (NASDAQ:SEDG) stock is up 8% to $59.81.
The catalyst is a fresh Enphase announcement tying its distributed power electronics work to the booming AI infrastructure build-out. SolarEdge is riding the same theme without a company-specific trigger.
Both stocks are bouncing off a rough recent stretch. Enphase shares closed yesterday at $48.34, and SolarEdge closed at $55.36.
Enphase Joins Open Compute Project to Push AI Power Standards
Enphase Energy announced it has joined the Open Compute Project (OCP) Foundation as a Platinum member to help advance AI data center power standards. The company will contribute work on higher-voltage direct current (DC) rack power architectures, including emerging designs such as ±400 VDC and 800 VDC, which are increasingly central to next-generation AI workloads.
The move connects directly to Enphase’s recently announced IQ Solid-State Transformer (IQ SST), a distributed architecture designed for AI data center power conversion. CEO Badri Kothandaraman stated that “open collaboration is essential to solving hard infrastructure problems at scale” and that Enphase is proud to contribute its distributed power electronics experience to next-generation data center power.
For Enphase, this reframes a microinverter and battery company as a power-electronics player aimed at the largest electricity demand story in tech. Reportedly, Enphase is now part of the roughly 700-member OCP consortium, underscoring the scale of the standardization effort.
Investors may want to temper their enthusiasm, though. The IQ SST opportunity is emerging, and Enphase’s own release flagged forward-looking caveats around standardization pace, technology validation, customer adoption, and execution risks of new market entry. In other words, it’s not yet a proven revenue driver.
SolarEdge Catches a Sympathy Bid
SolarEdge has no company-specific news today. The move in SolarEdge stock looks like a sympathy bounce tied to the broader solar and AI-data-center-power enthusiasm sparked by Enphase.
That said, SolarEdge has flagged AI data center power as a strategic priority. On the company’s Q1 2026 call, CEO Shuki Nir said that SolarEdge has “shifted decisively to offense and are focused on rolling out the SolarEdge Nexis platform and advancing our AI data-center power roadmap.”
The fundamentals remain mixed. SolarEdge posted Q1 2026 revenue of $310.5 million, up 42% year over year, but the stock carries a forward P/E ratio of 200x and an average analyst price target of $43.38, well below today’s level.
Context and What to Watch
Today’s pops sit on top of huge year-to-date runs. Enphase shares were up 51% year to date through yesterday’s close, while SolarEdge stock was up 92% year to date. Enphase carries a market cap of $6.37 billion and a forward P/E ratio of 23x.
Community sentiment around Enphase, per retail forums, points to a mix of heavy short-covering, bullish insider buying chatter, and high expectations for major partnerships in the power hardware sector. Investors may want to treat that as speculation rather than confirmed fact. A single-session move doesn’t reset the longer-term picture for either name.
Stock traders can watch for whether today’s gains hold into the close and whether peers in the solar and power-electronics complex follow through. The next data points to watch are Enphase’s next product update on the IQ SST and any read-through from hyperscaler power-procurement commentary. Cautious investors should consider keeping their position sizes modest given the volatility in both Enphase and SolarEdge shares.
