What happened
Shares of renewable energy stocks rose sharply in June, recovering from a rough few months of 2021. SunPower (SPWR +0.00%) jumped 24.9%, according to data provided by S&P Global Market Intelligence, as investors piled back into the solar industry. This continues a sharp recovery for SunPower over the past year, which traded as low as $5.19 in the last year and closed trading on July 2 at $28.81 per share.
Shares of First Solar (FSLR 3.58%) rose 18.9% as the company announced a $680 million investment in 3.3 gigawatts of U.S. manufacturing capacity. And fuel-cell producer Bloom Energy (BE 11.56%) rode the wave, gaining 11.2% in June.

So what
Renewable energy stocks have traded higher broadly because of two major trends over the past month. One is a steady rise in oil prices, which can often lead to an increase in solar energy stocks even if the two don't compete directly very often. The second is falling interest rates, which do boost renewable energy stocks by helping to lower the cost of financing energy projects. Rising rates in early 2021 sent renewable energy stocks lower, so this is a reversal of that trend.

Another help to the industry was a bill introduced in Congress by Sen. Jon Ossoff, a Georgia Democrat, who wants to give credits to solar companies that make products within the U.S. This is just proposed legislation, but it's clear that the solar industry has policy tailwinds. And that's welcome news after four years of the industry fighting an uphill battle in Washington, D.C.
SunPower, First Solar, and Bloom Energy are all U.S. based companies, so if there are subsidies or incentives for renewable energy companies building products here, they could be among the first to see a benefit.
Now what
Solar stocks have been on a wild ride over the past year, and last month was no different. The news about oil, interest rates, and policy bills was incrementally positive, but it will still take time for these changes to hit the bottom line. I'll be watching to see if any of the factors driving renewable energy stocks higher last month actually help operations later in the year.
We should start seeing growth and profitability improve after a rough year during the pandemic. But this is a highly competitive market, and sometimes price reductions will offset growth in volume, even in a good year. For now, investors think the finances of these companies are looking good enough to push their stocks sharply higher.
