10 Best Solar Stocks to Buy in 2025

As the world shifts toward renewable energy, the solar industry has become a key driver of growth and innovation. Solar power, with its scalability and declining costs, is at the forefront of this transition, offering significant opportunities for both sustainability and financial returns. Investing in solar stocks aligns with global goals of reducing carbon footprints while tapping into a rapidly expanding market. As demand for clean energy solutions continues to rise, the solar sector is poised for remarkable growth. Here are the top 10 solar stocks to consider in 2025:

 

First Solar Inc. (FSLR)

First Solar is one of the most well-established names in the solar industry, recognised globally for its advanced photovoltaic (PV) solar energy solutions. The company stands out due to its proprietary thin-film solar technology, which offers higher efficiency, better performance in hot climates, and a longer lifespan compared to conventional silicon-based panels. This unique technology gives First Solar a competitive edge in the rapidly growing utility-scale solar market.

In 2024, First Solar revised its annual sales forecast to between $4.10 billion and $4.25 billion, down from the previous estimate of $4.4 billion to $4.6 billion, due to market challenges. This growth was primarily attributed to a higher volume of solar modules sold to third parties, reflecting strong demand for its products. In Q3 2024, First Solar reported net sales of $887.7 million. The company also reported a net income per diluted share of $2.91, which was impacted by a $50 million product warranty reserve charge.

While First Solar remains optimistic about future growth, its revised forecasts reflect industry volatility, and 2025 projections may be subject to further adjustments. This optimistic outlook is backed by the company’s expanding production capacity, ongoing technological advancements, and growing demand from large-scale solar projects. Investor confidence in First Solar remains high, as reflected in its stock price, which stood at $185.99 in after-market trading following the Q3 2024 earnings release. With a strong balance sheet, a robust order backlog, and increasing global solar adoption, First Solar remains one of the top solar stocks to watch in 2025.

 

Enphase Energy Inc. (ENPH)

Enphase Energy is a leading provider of microinverter technology, which plays a crucial role in enhancing the efficiency and reliability of solar power systems. Unlike traditional string inverters, Enphase’s microinverters allow for panel-level energy conversion, improving overall system performance, especially in shaded or partially obstructed conditions.

In Q3 2024, Enphase Energy reported revenue of $380.9 million, a decrease from the prior quarter, primarily due to a decrease in the volume of megawatts sold and a product warranty reserve charge. Enphase faced a significant downturn in 2024, with total revenue dropping from $2.29 billion in 2023 to $1.33 billion, impacted by a decrease in U.S. demand and a softening European market. This decline was attributed to a slowdown in the residential solar market, particularly in the U.S., where higher interest rates and changing consumer behaviour impacted sales.

In November 2024, Enphase announced plans to reduce its global workforce by about 17%, affecting approximately 500 employees and contractors, to address declining demand in the residential solar market. Despite these setbacks, the company remains well-positioned for long-term growth due to its strong brand, innovative product offerings, and expansion into international markets.

As of March 29, 2025, Enphase’s stock was trading at approximately $114.48 per share. While the company has faced short-term volatility, its leadership in the microinverter segment and its ability to adapt to market changes make it a compelling long-term investment.
