Top Solar Energy Stocks to Watch for Growth in 2025

Looking to invest in the future of energy? Then solar stocks might be your next big move. With climate change pushing the world toward cleaner energy solutions, solar power is quickly becoming a favorite among environmentally conscious and forward-thinking investors.

But here’s the real question: Which solar energy stocks are worth keeping an eye on in 2025?

Let’s break it down and explore the top solar stocks that could shine bright this year and beyond.

Why Is Solar Energy a Smart Investment in 2025?

Before diving into the picks, let’s talk about why solar energy is such a hot topic (pun intended!).

Solar power is one of the fastest-growing energy sources in the world. Thanks to falling costs, government incentives, and a global shift toward sustainability, the solar industry is booming. In fact, experts predict that solar demand will continue climbing through 2025—meaning big opportunities for investors.

So, what does that mean for you? If you’re looking to grow your portfolio with clean, renewable energy, investing in solar stocks could be a bright idea.

Best Solar Energy Stocks to Watch in 2025

Let’s take a closer look at some top-performing and up-and-coming solar energy companies set to lead the charge this year.

1. First Solar (FSLR)

If you’ve heard of solar stocks, chances are you’ve heard of First Solar. The company is a giant in the industry—and for good reason.

Why it’s worth watching: First Solar specializes in thin-film solar panels, which are more efficient in hot climates. And with the U.S. pushing toward a net-zero carbon future, companies like First Solar stand to benefit.

Plus, here’s what’s exciting: Construction is underway for a massive new manufacturing facility in the U.S., which should help the company scale even faster. With its strong balance sheet and government backing, First Solar is well-positioned for growth in 2025.

2. Enphase Energy (ENPH)

You might not see Enphase panels on rooftops—but they’re a pretty big deal in the solar world.

Enphase builds microinverters, which convert sunlight into usable electricity. Their tech helps households optimize energy efficiency, making them a favorite among solar installers.

What’s exciting in 2025:

This company isn’t just about panels—they’re building the brains behind clean energy systems.

3. SolarEdge Technologies (SEDG)

SolarEdge is similar to Enphase in that it powers the tech behind solar panels. The difference? It focuses on power optimizers and intelligent energy management systems.

Why SolarEdge shines: Their strong partnerships in both residential and commercial sectors give them a diverse client base. They’re also expanding into EV charging and smart grid technology, which gives them a broader foothold in the clean energy space.

If you’re looking for a well-rounded solar tech company, SolarEdge is one to keep on your watchlist.

4. Array Technologies (ARRY)

Not all solar companies are about panels or inverters. Some, like Array Technologies, are more about making sure those panels work efficiently.

Array makes solar tracking systems that adjust the panels throughout the day to follow the sun. That can increase energy output by up to 30%.

What’s promising in 2025:

Think of them as the “coach” making sure the solar panels perform at their best.

5. Sunrun (RUN)

Sunrun is one of the largest residential solar installers in the U.S. They help homeowners go solar by offering installation, financing, and ongoing service plans.

Why it’s a stand-out: Sunrun has a customer base in the millions and a strong foothold in battery storage through partnerships, like the one with LG Chem.

Here’s why you should keep an eye on RUN:

For investors, this means the solar industry isn’t just a trend—it’s part of a larger economic and environmental shift.

What Should You Consider Before Investing?

One helpful tip? Diversify. A solar ETF (exchange-traded fund) lets you invest in multiple solar stocks at once, which spreads out risk.
