3 Solar Stocks to Watch Amid Policy and Tariff Headwinds

Why It Matters

Policy shifts and tariff pressures could reshape project economics, while resilient demand and favorable financing keep the solar market a key growth engine for clean‑energy investors.

Key Takeaways

• Solar demand strong despite policy and tariff headwinds.
• OBBBA reduces IRA tax credits, adds FEOC restrictions.
• Tariffs raise balance‑of‑system costs, offset module price declines.
• Canadian Solar, Tigo, Sunrun show earnings upside.
• Industry EV/EBITDA ~5.9×, far below S&P 500 multiples.

Pulse Analysis

The solar sector’s momentum is anchored in a surge of residential and utility‑scale installations paired with battery storage, a trend driven by decarbonization goals and rising electricity prices. Lower Federal Reserve rates have trimmed borrowing costs, improving project cash flows and accelerating approvals. This financing tailwind, combined with an expected 17% increase in solar generation in 2026, underscores the industry’s capacity to capture a larger share of the U.S. electricity mix, which the EIA projects will reach 8% by 2026.

However, the legislative landscape has grown more complex. The One Big Beautiful Bill Act slashes key tax credits from the Inflation Reduction Act and imposes Foreign Entity of Concern restrictions that could limit access to critical components. While developers grapple with uncertain permitting and supply‑chain guidance, long‑term demand remains solid, with SEIA forecasting 44 GWdc of new capacity in 2026 and a cumulative 246 GWdc through 2030. The policy shock is likely to be absorbed over time as the market adjusts its financing structures and domestic manufacturing ramps up.

From an investment perspective, the solar industry trades at a modest 5.94× EV/EBITDA, well below the S&P 500’s 17.73× multiple, offering a valuation cushion. Stocks such as Canadian Solar, Tigo Energy and Sunrun have posted significant earnings estimate upgrades, reflecting confidence in their growth trajectories despite sector‑wide earnings pressure. Over the past year, the solar index outperformed both its sector and the broader market, delivering a 40.4% return. For investors seeking exposure to clean‑energy growth, these companies combine strong fundamentals with attractive pricing relative to peers.
