All Aboard the Stock-Market Solar Coaster
Much of the climb in solar stocks looks justified by growth prospects, but buyers may still be in for a bumpy ride

Solar stocks are sizzling—quite an accomplishment for the simplest and most mature of the green-energy technologies. Finding companies that could keep shining might require looking in less obvious places.
The MAC Global Solar Energy Index has generated a 233% return including dividends for dollar investors during the past year. That is well ahead of returns from wind-turbine makers Vestas and Siemens Gamesa, nevermind the S&P 500’s 15%.
As public and political support for green power has broadened, markets have come to expect a decadeslong renewables rollout. It is hard to see any catalyst for a change in sentiment, says Sam Arie, a veteran utilities analyst at UBS. Solar panels can be the cheapest way to generate electricity in many parts of the world. “In some cases it is even cheaper to build a new solar farm than run existing coal plants,” says Alex Monk, a portfolio manager at asset manager Schroders.
The catch is that the shift to renewables doesn’t guarantee shareholder returns. To justify high valuations, investors need to ensure companies have a defensible business as well as growth prospects.
Solar investors have already experienced at least two stomach-churning cycles. A key lesson has been that making panels themselves is a low-margin, hypercompetitive market best avoided. But other parts of the value chain offer better prospects.
For example, SolarEdge and Enphase make power inverters, which convert a solar panel’s power to alternating current and adjust performance to maximize output. Their Nasdaq-listed shares have returned 179% and 444% respectively during the past year and now trade for 72 and 93 times forward earnings. That is a lot of growth priced in. However, the technologies are patent-protected and could also be central to managing a smart home’s power between electric vehicles, solar panels, batteries and the like—a potentially vast market.
Developers are another option. They bid for, build and run solar farms. While installing the panels isn’t complex, experience is valuable when pricing bids and navigating the permitting process, and scale is crucial to sourcing panels effectively.
NextEra Energy, Enel and Iberdrola have built huge renewable-power farms as part of wider utility businesses and have ambitious rollout plans for solar and wind. Their shares have given investors total returns of between 16% and 28% over a year, and now change hands for between 15 and 32 times forward earnings. Barclays utilities analyst Dominic Nash credits part of the rise to general growth investors coming into the sector for the first time.
Then there are U.S. residential developers, which offer homeowners rooftop solar-panels paired with battery storage. The products provide added reliability, and monthly payments for the cost of batteries and solar panels that are often lower than existing utility bills. “It’s a pretty easy sale,” says Stephen Byrd, an analyst at Morgan Stanley.
Shares in SunPower and Sunrun, two such developers, trade at Tesla-type multiples, 118 times and 360 times forward earnings respectively. Revenues will grow—U.S. solar penetration will rise from 3% now to 14% by 2030, says Mr. Byrd—but margins will also come under pressure once installers compete head-to-head rather than with incumbent utilities.
Investors need to choose carefully as the stock-market solar coaster speeds up again. The general direction of travel may be up, but it likely still has plenty of twists and turns in store.

Government spending, including Biden’s Inflation Reduction Act, has helped drive a gap between clean-energy spending and fossil-fuel investments

Investments in solar power are on course to overtake spending on oil production for the first time, the foremost example of a widening gap between renewable-energy funding and stagnating fossil-fuel industries, according to the head of the International Energy Agency.
More than $1 billion a day is expected to be invested in solar power this year, which is higher than total spending expected for new upstream oil projects, the IEA said in its annual World Energy Investment report.
Spending on so-called clean-energy projects—which includes renewable energy, electric vehicles, low-carbon hydrogen and battery storage, among other things—is rising at a “striking” rate and vastly outpacing spending on traditional fossil fuels, Fatih Birol, the IEA’s executive director said in an interview. The figures should raise hopes that worldwide efforts to keep global warming within manageable levels are heading in the right direction, he said.
Birol pointed to a “powerful alignment of major factors,” driving clean-energy spending higher, while spending on oil and other fossil fuels remains subdued. This includes mushrooming government spending aimed at driving adherence to global climate targets such as President Biden’s Inflation Reduction Act.
“A new clean global energy economy is emerging,” Birol told The Wall Street Journal. “There has been a substantial increase in a short period of time—I would consider this to be a dramatic shift.”
A total of $2.8 trillion will be invested in global energy supplies this year, of which $1.7 trillion, or more than 60% will go toward clean-energy projects. The figure marks a sharp increase from previous years and highlights the growing divergence between clean-energy spending and traditional fossil-fuel industries such as oil, gas and coal. For every $1 spent on fossil-fuel energy this year, $1.70 will be invested into clean-energy technologies compared with five years ago when the spending between the two was broadly equal, the IEA said.
While investments in clean energy have been strong, they haven’t been evenly split. Ninety percent of the growth in clean-energy spending occurs in the developed world and China, the IEA said. Developing nations have been slower to embrace renewable-energy sources, put off by the high upfront price tag of emerging technologies and a shortage of affordable financing. They are often financially unable to dole out large sums on subsidies and state backing, as the U.S., European Union and China have done.
The Covid-19 pandemic appears to have marked a turning point for global energy spending, the IEA’s data shows. The powerful economic rebound that followed the end of lockdown measures across most of the globe helped prompt the divergence between spending on clean energy and fossil fuels.
The energy crisis that followed Russia’s invasion of Ukraine last year has further driven the trend. Soaring oil and gas prices after the war began made emerging green-energy technologies comparatively more affordable. While clean-energy technologies have recently been hit by some inflation, their costs remain sharply below their historic levels. The war also heightened attention on energy security, with many Western nations, particularly in Europe, seeking to remove Russian fossil fuels from their economies altogether, often replacing them with renewables.
While clean-energy spending has boomed, spending on fossil fuels has been tepid. Despite earning record profits from soaring oil and gas prices, energy companies have shown a reluctance to invest in new fossil-fuel projects when demand for them appears to be approaching its zenith.
Energy forecasters are split on when demand for fossil fuels will peak, but most have set out a timeline within the first half of the century. The IEA has said peak fossil-fuel demand could come as soon as this decade. The Organization of the Petroleum Exporting Countries, a cartel of the world’s largest oil-producing nations, has said demand for crude oil could peak in developed nations in the mid-2020s, but that demand in the developing world will continue to grow until at least 2045.
Investments in clean energy and fossil fuels were largely neck-and-neck in the years leading up to the pandemic, but have diverged sharply since. While spending on fossil fuels has edged higher over the last three years, it remains lower than pre pandemic levels, the IEA said.
Only large state-owned national oil companies in the Middle East are expected to spend more on oil production this year than in 2022. Almost half of the extra spending will be absorbed by cost inflation, the IEA said. Last year marked the first one where oil-and-gas companies spent more on debt repayments, dividends and share buybacks than they did on capital expenditure.
The lack of spending on fossil fuels raises a question mark around rising prices. Oil markets are already tight and are expected to tighten further as demand grows following the pandemic, with seemingly few sources of new supply to compensate. Higher oil prices could further encourage the shift toward clean-energy sources.
“If there is not enough investment globally to reduce the oil demand growth and there is no investment at the same time [in] upstream oil we may see further volatility in global oil prices,” Birol said.
