5 Pick-and-Shovel Solar Stocks for the Green Energy Gold Rush

SolarEdge Technologies

• Market value: $14.7 billion

Israel-based SolarEdge Technologies (SEDG, $281.44) makes inverters: a key component of the microgrid that delivers solar energy to where it's needed in homes, schools, businesses, campuses and beyond.

Shares of SEDG have been on a tear the last two years. However, since hitting an all-time closing high near $365 in December, shares slumped down to around $200 this spring before rebounding to current levels.

Sentiment has likely tempered on the solar stock thanks to a modest 2% rise in 2020 revenues and a 3% drop in net income. The company's earnings release was mum on the precise reason for this, but declines in both gross and operating margins suggests that as the market for microgrids expands, so too do costs, at least at this stage of the game.

This should be of little concern for longer-term investors looking at solar stocks.

First, SEDG is sitting on just over $680 million in cash and marketable securities as of June 30, with only a few hundred thousand dollars in debt due this year. Next, cash flow from operations for 2020 was $223 million, almost twice reported net income, and this easily covered $126 million in capital expenditures (capex) with a sizable cushion left over.

Finally, about 40% of SEDG sales come from the U.S. While renewable energy policies have been wobbly, a progressive administration coupled with 37 states that have renewable energy targets offers a good setup for sales and earnings growth.

Consensus estimates for SolarEdge Technologies' adjusted fiscal 2021 earnings are $5.09 per share, which, if realized, would represent a 24% improvement from 2020 – a pretty nice bump.

Enphase Energy

• Market value: $23.3 billion

Enphase Energy (ENPH, $172.91) also manufactures inverter systems. Unlike "string converters" made by SolarEdge, which draw power wholesale from all the panels in an installation, Enphase sells microinverters, which draw energy from individual panels as needed or as conditions allow, and, as a result, can be more efficient.

Though microinverters cost more, the market for them may grow faster because they can be more responsive to site-specific conditions. Estimated average annual global growth for microinverters through 2025 is 21% versus about 15% for string inverters, according to Research and Markets, a market research firm.

For investors who believe in the underlying fundamentals of the solar market and who are looking to buy the dips, Enphase might be the stock for you.

Shares of the solar stock dropped from around $215 per share in February to about $115 in mid-May, thanks in part to Enphase's first-quarter report. While sales grew an impressive 46% year-over-year, earnings declined and ENPH reduced its second-quarter outlook based on semiconductor shortages and supply chain interruptions.

But things have improved for the stock since then, thanks to a Q2 report that saw earnings more than triple to 53 cents per share, which easily beat estimates for 43 cents.

Enphase should be able to weather any near-term headwinds. It's sitting on about $1.7 billion in cash, and while long-term debt is just over $900 million, the current portion is only $85 million. Meanwhile, operations last year threw off about $216 million in cash, while capital expenditures were modest at about $25 million.

Generac Holdings

• Market value: $26.9 billion

Generac Holdings (GNRC, $425.87) has grown handsomely selling backup generators to consumers who have become more attuned to and proactive toward power outages. Ice storms in Texas and fires in California offer vivid reminders about the importance of backup power.

But in 2019, Generac entered the battery storage business with a pair of acquisitions. By purchasing Pika Energy and Neurio Technology, GNRC positioned itself to develop and distribute its PWRcell and PWRview solar power products.

Sales are small and not broken out on earnings reports, but Generac touts PWRcell as a high-growth area for the company. And what we're seeing with PWRcell today might be the thin end of the wedge – a setup many investors like. Think Apple (AAPL), where the relatively small services division is expected to be the next big leg of growth for the company, and contributed to about 19% of total sales in its fiscal second quarter. And Amazon.com's (AMZN) cloud division – at a little more than 10% of total sales – is seen as one of the linchpins of the company's growth.

Generac enters the solar business with two distinct advantages. First, it's reliably growing in its core generator business, increasing sales and cash flow at an average annual rate of 10% during the last five years, according to Value Line. Notably, cash flow from operations last year was some $487 million, plenty to finance its foray into the solar business.

Second, unlike Enphase and SolarEdge, which rely principally on third-party sellers and are relatively young companies, Generac has been doing business since 1959, has a global network of 7,000 dealers and has decades of customer data that it can ply with its solar offering.

Shares have been highfliers, up more than 410% since April of last year. Arguably, much of the enthusiasm is being driven by generators, but GNRC could emerge as one of the best solar stocks as its green energy business takes hold.

Daqo New Energy

• Market value: $4.0 billion

Daqo New Energy (DQ, $54.01) is based in China and produces polysilicon, which is used to make solar panels. Right now, China is the world's largest producer of solar panels, and as a result, Daqo is well-positioned to capitalize on the country's leadership in this green energy space.

Another driver for Daqo shares is that demand for polysilicon is increasing and this is boosting prices. For instance, according to Bernreuter Research, in 2021 alone, prices per kilogram for polysilicon have risen from $11 to nearly $28 – and much of that growth goes straight to Daqo's top line. Daqo is solidly profitable, and price increases for its core product are driving increases in its gross and operating margins.

Chinese companies have been chipping away at the hegemony of Western polysilicon producers. Daqo, which is among the top 10 polysilicon producers in the world, typifies this trend. The company plans to increase capacity to 270,000 metric tons by the end of 2024, representing roughly 50% compound annual growth over that time.

With solar booming, Daqo will presumably find a home for all of this new polysilicon, at what looks like increasing prices and better margins. This could make DQ one of the best solar stocks to have on your radar.

CleanSpark

Market value: $469.8 million

Almost nothing in this world works without software, and solar power is no exception. CleanSpark (CLSK, $13.20) offers a suite of software solutions that provide end-to-end microgrid modeling, communications and energy management.

CleanSpark is tiny, but its market cap, at about $550 million, suggests some investors think it could be mighty. CLSK is not for the faint of heart, but the fact that it's showing some momentum above and beyond what's been seen in the broader green energy sector is notable. In its recently reported fiscal third quarter, the company announced that nine-month revenues were $22.3 million – up 176% year-over-year.

CleanSpark is unprofitable on a generally accepted accounting principles (GAAP) basis, but analysts believe CLSK will flip to a 41-cent adjusted profit this fiscal year, from a $2.44 loss in fiscal 2020. If it does, catching the solar stock now, while it's trading at half of what it was at the start of 2021, might be a tenable first step in building a larger position long term.

Also noteworthy, CleanSpark is ramping up its participation in the Bitcoin mining business. Mining revenue didn't appear as a line item on its most recent annual report, but it did show up in CLSK's first-quarter results. And in April of this year, the company announced a material expansion of its Bitcoin mining operations.

Carbon-belching Bitcoin mining and renewable energy can be somewhat at odds, but CleanSpark notes that 95% of the power for its mining operations is carbon-free – an important marker for ESG investors, those focused on environmental, social and corporate governance, and perhaps a source of buying support for the solar stock going forward.
