In this article, we discuss 12 best solar and battery stocks to buy.

According to the International Energy Agency, solar energy is set to overtake coal in power capacity by 2027. The demand for solar installations in the US is set to triple by 2028 to 378 GW and the industry has experienced record success in 2023. The residential component for solar installations has increased by 30%, as compared to last year. Similarly, commercial growth for the year is expected to be around 12% in 2023. Although the industry has seen an increase in the cost of electricity due to supply chain issues and global inflation, solar energy still makes for a lower cost of power generation, as compared to fossil fuel. Over the last year, the industry has seen an unprecedented inclusion in policy making. The International Energy Agency has highlighted the importance of solar installations to counter Europe’s dependence on Russian gas. In line with this, around 26 countries have added at least 1 GW of solar energy installations over the past year. Experts have forecasted the cost to steadily decrease to pre-pandemic prices, with new advancement and installations that increase the photovoltaic capacities over time.

Similar to the solar industry, electric vehicles have seen their sales triple over the last two years. As of the first quarter of 2023, EV sales reached 2.3 million units. The International Energy Agency has forecasted a 35% year-over-year growth by the end of 2023. In China, the demand for electric vehicles has grown by 70% over the last year. In contrast, the US market has seen the demand increase by 80%. However, this increase in demand brings tough challenges. The biggest constraint for the industry is sourcing the crucial raw materials. Globally, the supply for lithium rose by 180% in 2022. Despite this significant increase, the industry experienced a shortage of lithium. To put this into perspective, about 60% of all the demand for lithium originates for EV applications. In addition to this, cobalt and nickel shortages continue as well. While mining efforts have increased globally, there is a strong need for more innovation in the industry. Companies have already focused on optimizing battery sizes that can result in a lower dependence on crucial materials.

Park’s Park West Asset Management is the biggest stakeholder of the company, with 5.4 million shares worth $80.7 million.

Here is what Long Cast Advisers said about Enovix Corporation in its Q4 2022 investor letter:

“Enovix Corporation is what I’ll endearingly call a “shitco” meaning it’s pre-revenue / pre-profit but with a massive addressable market, so if it succeeds, the potential reward offsets the risks. I think there’s room in the portfolio for a few smaller investments like this, but if I am consistently wrong over time, I’ll change course (SNES and SANW also fall into this category, and so far I’ve been wrong about those, but like ENVX, they are small positions with long time horizons).

ENVX makes lithium batteries using silicon instead of graphene as the anode. Silicon as an anode offers many benefits – faster charging, longer charge periods and longer battery life – but it has a major drawback in that it swells when it charges, and this causes battery degradation and mechanical failure…” (Click here to read the full text)

8. Sunrun Inc. (NASDAQ:RUN)

Number of Hedge Fund Holders: 27

Next on our list of the best solar energy stocks is Sunrun Inc. (NASDAQ:RUN), which specializes in the development, installation, and maintenance of photovoltaic systems and battery solutions.

Here is what Horizon Kinetics has to say about Sunrun Inc. in its Q2 2021 investor letter:

“What this table did not cover is valuation. What’s expensive, what’s cheap? A good business that is too expensive is not a good investment. The most expensive business on the table is Sunrun. Sunrun is the nation’s largest residential rooftop solar panel system seller/installer. Sunrun’s valuation might also shed Thumbnail valuation.

To start at the top of the income statement, Sunrun shares trade at 10.3x revenues. The most profitable company in the S&P 500, Microsoft, trades at 13x revenues. Sunrun operates at a loss. Obviously, not only is tremendous growth anticipated, but tremendous profitability, too.

Let’s simply accept that investors have correctly anticipated Sunrun’s future success and make that the starting point for a valuation exercise.

If, 10 years from now, Sunrun is ultimately valued at 25x net income, and if today’s $9.5 billion valuation is appropriate, that would require $380 million of net income ($9,500 million ÷ 25).

Let’s say Sunrun will have the same net profit margin as the average S&P 500 company, which is 10%. That means it would need $3,800 million of sales to generate that level of earnings ($380 mill ÷ 10%).

Since sales are now $920 million, they would have to rise by 4.1x in the next 10 years. That would require annual sales growth of 15.2%. (Click here to read full text)

Carillon Tower Advisors had this to say about Albemarle Corporation in its investor letter from the last quarter of 2022:

“Albemarle Corporation is a global specialty chemicals company with leading positions in lithium, bromine, and refining catalysts. The stock gave back some of its recent gains amid investor concerns about how the future price of lithium could be affected by a potential decelerating rate of growth in overall electric vehicle (EV) production and demand, primarily in China.

This phenomenon is accelerating revenue growth for these companies.”

2. Enphase Energy, Inc. (NASDAQ:ENPH)

Number of Hedge Fund Holders: 55

Enphase Energy, Inc. is a provider of photovoltaic solutions, with a key focus on the residential market. On July 20, the stock experienced a 4.8% decline, following Wolfe Research downgrading Enphase Energy, Inc. from Outperform to Peer Perform. This is because the US residential market has seen a bit of decline, as compared to expectations. Although the company has experienced a strong increase internationally over the last 2 years, Wolfe Research analyst Steve Fleishman believes that the market will only get more competitive. However, Enphase Energy, Inc. remains one of the best solar and battery stocks to buy according to hedge funds.

According to Insider Monkey’s first quarter database, 55 hedge funds were bullish on Enphase Energy, Inc., as opposed to the 63 funds in the last quarter. Philippe Laffont’s Coatue Management remains the largest shareholder of the company, with 714,442 shares worth $150.2 million.

Here is what Aristotle Atlantic Large Cap Growth Strategy had to say about Enphase Energy, Inc. in its investor letter for the first quarter of 2023:

“Enphase Energy, Inc. designs, develops, manufactures and sells home energy solutions in the U.S. and internationally for the solar industry. The company is the world’s leading manufacturer of microinverters that convert solar-generated D.C. energy to A.C. energy usable in homes and buildings. Enphase introduced the world’s first microinverter system in 2008 and has expanded its offerings to include battery storage systems and proprietary technologies that provide energy monitoring and control services for solar energy systems. It sells its products and solutions directly to solar system distributors, large installers and strategic partners.

We see Enphase having a substantial market share that is gained through a premium product offering, superior customer service and the development of a large and diverse network of solar installers and distributors. The company’s products and services address a growing residential solar market. Coupling battery backup systems with existing and newly installed residential solar systems could accelerate the company’s revenue and earnings growth over the next several years, in our view. Additionally, commercial and international expansion offer additional revenue and earnings upside. Enphase also plans to expand manufacturing capacity in the U.S. during 2023 to benefit from tax incentives related to domestic production included in the Inflation Reduction Act (IRA).”

1. Tesla, Inc. (NASDAQ:TSLA)

Number of Hedge Fund Holders: 82

Tesla, Inc. is synonymous with electric vehicles and the ecosystem to be built around it. The company is a market leader and specializes in the development, production, and commercialization of electric vehicles, battery solutions, and energy generation. On July 24, EV stocks saw an increase in price, after a decline last week. In line with this, Tesla, Inc. experienced a 3.22% increase in share price, despite UBS’ latest review for the stock. This can be attributed to the company’s interest in building a plant in India, following a momentous visit of Indian diplomats to the White House.

According to Insider Monkey’s first quarter database, 82 hedge funds hold a bullish position in Tesla, Inc., compared to 91 funds in the last quarter of 2022. D E Shaw is a prominent shareholder in Tesla, Inc., with 6.2 million shares worth $1.295 billion.

Baron Opportunity Fund had this to say about Tesla, Inc. in the first quarter of 2023:

“Tesla, Inc. designs, manufactures, and sells EVs, related software and components, and solar and energy storage products. Following a sharp decline at the end of 2022, Tesla’s stock rebounded in the first quarter of 2023 on investor expectations that Tesla will continue to grow vehicle deliveries and maintain solid gross and operating margins despite a potential recession, competition in China, and vehicle price reductions. We wrote a long piece on Tesla last quarter and refer readers back to it, because for long-term investors not much has changed over the last three months. Tesla did hold its first Investor Day in March, and several Baron analysts and portfolio managers attended. We toured the Austin Gigafactory, drove in a Cybertruck, boarded a Semi truck, and spoke with a wide swath of Tesla senior managers. During the formal presentation, Tesla highlighted, among other things: (1) its broad and deep bench of executive talent supporting CEO Elon Musk; (2) its “Master Plan 3–Sustainable Energy for All of Earth,” which featured EVs, renewable power from solar and wind, and stationary electric storage; (3) its vehicle assembly innovations, including massive casted parts (building Model Y bodies with single front and rear castings, replacing a substantial number of parts and fastening steps), a stainless steel exoskeleton (for Cybertruck), and its next-generation highly efficient “unboxed process” for its next-gen $25,000 vehicle; (4) a future permanent[1]magnet electric motor that will not require any rare earths; and (5) the massive untapped market opportunity for commercial stationary electric storage, branded Megapack, as the world steadily shifts to renewable energy. As long-term shareholders, we have witnessed Tesla exploit its innovative Model 3/Y now-global mass-market platform to increase vehicle deliveries from barely a standing start to over 1.3 million units, while achieving industry-leading margins and reinforcing its iron-clad balance sheet to almost $23 billion in cash (and effectively no recourse debt). We expect Tesla’s next-generation EV and Megapack products to have a similar impact on company results.”
