The solar energy boom is the modern equivalent of the California Gold Rush of 1848.
Data from Wood Mackenzie Power & Renewables and the Solar Energy Industries Association notes that it took 40 years to reach 1 million solar installations in the U.S., but just three more years to hit 2 million installations. And the forecast for 2021 alone is 3 million installations.
Green energy exchange-traded funds (ETFs) are on the rise as earnings improve and investors pile into solar stocks. This is evidenced in the bellwether Invesco Solar ETF (TAN), which has more than doubled over the past year, though lately, it has cooled off.
With climate change firmly atop the Biden administration's agenda, the set up for solar stocks looks good.
And like the supply companies that profited during the gold rush selling picks and shovels to eager prospectors, solar energy offers a similar "pick and shovel" opportunity. Companies that make components, batteries, the materials to produce panels or the software to manage them are riding the coattails of the inexorable march away from fossil fuels and toward solar power.
Here are five of the best solar stocks that offer a differentiated strategy for profiting from the green energy boom.

Data is as of May 10.
- Market value: $11.1 billion
Israel-based SolarEdge Technologies (SEDG, $213.34) 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, but have declined more recently to current levels near $210 since hitting an all-time closing high near $365 in December.
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 $1 billion in cash and marketable securities, with just $17 million 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 set up for sales and earnings growth.
Consensus estimates for SolarEdge Technologies' fiscal 2021 are $3.82 per share, which, if realized, would represent a 37% jump from 2020 basic earnings per share (EPS) of $2.79 – a pretty nice bump.
- Market value: $16.0 billion
Enphase Energy (ENPH, $118.12) 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 are off from their February highs of over $200, and took another hit after 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.
Enphase can weather these kinds of storms for now. It's sitting on about $1.5 billion in cash, and while long-term debt is just over $900 million, the current portion is just $84 million. Operations last year threw off about $216 million in cash, while capital expenditures were modest at about $25 million.

- Market value: $19.2 billion
Generac Holdings (GNRC, $305.21) 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 set up 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 at Amazon.com (AMZN), its web services division – at about 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 250% 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: $5.3 billion
Daqo New Energy (DQ, $72.15) 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 $19, growth which 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 with its recently announced production expansion which will add 35,000 metric tons of capacity, an increase of some 45%.
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 DAQO one of the best solar stocks to have on your radar.
Market value: $549.6 million
Almost nothing in this world works without software, and solar power is no exception. CleanSpark (CLSK, $16.23) 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 the first three months of 2021, sales were up over 120% year-over-year. And as of mid-April, the company reported significant growth in its backlog – up 220% from mid-February.
CleanSpark doesn't make money yet, but analysts are forecasting it will report a profit at the end of this quarter. If it does, catching the solar stock now might be a tenable first step in building a larger position long term. Of note, the second quarter earnings estimate, now 8 cents per share , has come down from an estimated 22 cents per share earlier this year, so conviction may be on the wane.
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 or support for the solar stock going forward.
