First Solar or Nextracker? Uncovering the Smarter Solar Investment Play

First Solar (FSLR) and Nextracker (NXT) present contrasting investment profiles within the rapidly expanding global solar sector. FSLR, a thin-film module manufacturer, boasts strong solvency, $19.8 billion in long-term contracts, and plans to expand capacity to over 25 GW by 2026, offering a more attractive valuation at 8.32x forward earnings despite recent downward earnings estimate revisions and risks from new import tariffs and module technical issues. Conversely, NXT, a solar tracker provider, has significantly outperformed FSLR in stock gains (up 26.5% year-over-year vs. FSLR's -31.6%), demonstrating strong global momentum with 10 GW deployed in India and strategic acquisitions like Bentek, though it also faces tariff-related cost pressures. While FSLR appeals to value-focused investors seeking long-term returns, NXT offers dynamic growth potential with recent upward earnings estimate revisions.

Analysis

First Solar (FSLR) and Nextracker (NXT) present a clear dichotomy for investors in the solar sector, balancing long-term value against near-term growth momentum. FSLR offers substantial revenue visibility with $19.8 billion in contracted future sales through 2030 and a defined capacity expansion to over 25 GW by 2026. Its financial position is solid, with $891 million in cash against approximately $525 million in total debt, and it trades at a more attractive forward earnings multiple of 8.32x. However, this is counterbalanced by significant headwinds, including an expected loss of $56-$100 million from technical issues in its Series 7 modules, recent downward revisions to its near-term earnings estimates, and stock underperformance, having declined 31.6% over the past year. Conversely, NXT demonstrates strong operational momentum, evidenced by a major 550 MW European project win, surpassing 10 GW in tracker deployments in India, and the strategic acquisition of Bentek for $78 million to enhance its U.S. supply chain. This is reflected in its stock's 26.5% gain over the past year and recent upward revisions in near-term earnings estimates. Despite this, NXT faces an 8.3% earnings decline forecast for fiscal 2026 and trades at a higher valuation of 14.55x forward earnings. Both companies face margin pressure from U.S. import tariffs on solar components and raw materials.

Key Decisions for Investors

• Value-focused investors may find First Solar's valuation compelling given its $19.8 billion contract backlog, but should monitor the financial impact of its module technical issues and the negative trend in near-term earnings estimates.
• Growth-oriented investors could favor Nextracker due to its strong stock momentum, strategic acquisitions, and positive analyst sentiment, while acknowledging the higher valuation and a forecasted 8.3% earnings decline in fiscal 2026.
• Investors should consider that both companies are exposed to U.S. trade policy risks, making cost management and supply chain resilience critical performance indicators to track.
• Monitor First Solar's progress in resolving its Series 7 module issues, as a swift resolution could be a positive catalyst, while tracking Nextracker's integration of Bentek as a key indicator of its ability to mitigate supply chain risks.
