Top Solar Stocks for Q2 2021

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 the Invesco Solar ETF (TAN), have dramatically outperformed the broader market over the past year. TAN has provided a total return of 266.8% over the last 12 months, well above the Russell 1000’s total return of 66.1%, as of March 12, 2021. These figures are exceptionally high as they are based off of severely depressed equity prices during the bottom of last year’s bear market. All statistics in the tables below are as of March 12, 2021.

Here are the top 3 solar stocks with the best value, the fastest growth, and the most momentum.

These are the solar stocks with the lowest 12-month trailing price-to-earnings (P/E) ratio. Because profits can be returned to shareholders in the form of dividends and buybacks, a low P/E ratio shows you’re paying less for each dollar of profit generated.
