Enphase Energy (NASDAQ: ENPH), a prominent provider of residential solar energy solutions, has experienced a significant decline in its stock, falling nearly 40% this year and over 70% from its 52-week peak of around $140. What factors are contributing to this substantial drop? The company is facing a harsh mix of industry challenges and its own operational difficulties that have formed a perfect storm.
The primary issue impacting Enphase has been the drop in residential solar demand. The firm’s revenue has taken a hit, decreasing 42% from $2.29 billion in 2023 to just $1.33 billion in 2024. This isn’t solely an Enphase issue—it’s occurring throughout the entire residential solar market as customers have largely refrained from making significant solar investments. It is precisely this downside risk, compared to the relative upside trade-offs we made – at scale, in constructing the Trefis High Quality (HQ) strategy that has achieved over 91% returns since its inception and outperformed the S&P.

High interest rates are a significant factor, raising the costs for homeowners to finance solar installations. When faced with a solar system costing over $10,000 and skyrocketing borrowing costs, many individuals are simply saying, “not now.” To complicate matters, the company is burdened with excess inventory. Similar to many solar companies, Enphase accumulated stock based on the expectation of stronger demand that has not materialized, adding more stress to the company’s margins. As a result, Enphase’s operating margin fell from 20% in 2023 to below 7% last year.
The earnings situation has also been difficult. Enphase consistently falls short of Wall Street’s expectations, and their guidance isn’t instilling much optimism in investors. In the last quarter, they reported earnings of $0.68 per share on $356 million in revenue, failing to meet predictions of $0.71 per share on $362 million in revenue. Even more troubling, management projected just $360 million in Q2 sales at the midpoint, significantly lower than the $380 million analysts were anticipating.
Moreover, there’s the tariff situation. New tariffs of up to 3,500% on solar components—particularly battery cells from China and Southeast Asia—are poised to severely impact Enphase’s profit margins. The company has already indicated that these tariffs will affect margins in the upcoming quarters, with an even greater negative effect expected later this year. They are attempting to move battery cell production from China to the U.S. to avoid the tariffs and secure some tax credits, but this transition requires time and resources. In the meantime, margins may suffer by several hundred basis points.
The general economic landscape isn’t providing any relief either. With high interest rates and growing concerns about the economy, homeowners are understandably cautious about making large purchases like solar panels. This kind of environment typically leads to reductions in discretionary spending.
Enphase has attempted to address the situation by reducing costs, including laying off 500 employees and terminating some manufacturing contracts late last year. However, these actions merely underscore how challenging the circumstances have become and have not succeeded in convincing investors that brighter days lie ahead.
The bottom line is that Enphase finds itself in a challenging predicament. The company needs a rebound in residential solar demand and for the tariff situation to stabilize before any improvements can be seen. Until then, the stock will likely continue to experience pressure from both the fundamental business issues and investor doubts about when—or if—the solar market will recover. In fact, the predicament of Enphase Energy illustrates the risks of heavily investing in a single stock. Establishing a diversified portfolio is essential for balancing risk and reward. For instance, the Trefis High Quality (HQ) strategy, which emphasizes risk-reward balance, has consistently outperformed the S&P 500, Nasdaq, and Russell 2000 since its inception.
