The solar energy industry has grown rapidly even as fossil fuels remain the dominant source of global energy use. Solar industry companies come from multiple sectors, including utilities, industrial, and energy, and include popular stocks such as SolarEdge Technologies (SEDG) and Sunrun Inc. (RUN). While some large utilities and energy companies have solar and renewable energy divisions, these businesses typically are not included in the industry’s listings because the parent’s primary focus is not solar.
Solar stocks, represented by an exchange-traded fund (ETF)–the Invesco Solar ETF (TAN)–have significantly underperformed the broader market over the past year. TAN has provided a total return of -5.7% over the last 12 months, behind the Russell 1000’s total return of 8.2%. These market performance numbers and all statistics in the tables below are as of March 8, 2022.
Here are the top three solar stocks with the best value, the fastest growth, and the most momentum. Note that we include earnings per share (EPS) growth for the growth stocks section because most of the rally in natural gas has happened recently. As a result, the growth measure, which only looks at the most recent quarter, will show movement first, whereas in the list of stocks we looked at, many of them still didn’t have positive earnings over a 12-month trailing period. Gas has spiked in price since the Russian invasion of Ukraine because Russia is a major gas producer and has since been subject to major sanctions.
Best Value Solar Stocks
These are the solar stocks with the lowest 12-month trailing price-to-sales (P/S) ratio. For companies in early stages of development or industries suffering from major shocks, this can be substituted as a rough measure of a business’s value. A business with higher sales could eventually produce more profit when it achieves, or returns to, profitability. The price-to-sales ratio shows how much you’re paying for the stock for each dollar of sales generated.

Fastest Growing Solar Stocks
These are the top solar stocks as ranked by a growth model that scores companies based on a 50/50 weighting of their most recent quarterly YOY percentage revenue growth and most recent quarterly YOY earnings-per-share (EPS) growth. Both sales and earnings are critical factors in the success of a company. Therefore, ranking companies by only one growth metric makes a ranking susceptible to the accounting anomalies of that quarter (such as changes in tax law or restructuring costs) that may make one figure or the other unrepresentative of the business in general. Companies with quarterly EPS or revenue growth of more than 2,500% were excluded as outliers.
