The solar energy industry has been growing rapidly even as fossil fuels remain the dominant form of energy. Companies considered to be solar-focused come from multiple sectors, including utilities, industrial, and energy and include popular stocks such as First Solar, Inc. (FSLR) and SunPower Corp. (SPWR). While some of the major mainstream utilities and energy companies also have solar and renewable energy divisions, these corporations are not typically included in listings of solar companies because they do not focus the majority of their efforts in this area. In the 12-month trailing period, the solar industry has far outpaced the growth of the S&P 500, as the Invesco Solar ETF (TAN) saw a price change of 61.8% compared to S&P gains of 26.4%. All figures are as of January 8, 2020.
Here are the top solar stocks with the best value, the fastest earnings growth, and the most momentum.
Best Value Solar Stocks
These are the solar sector stocks with the lowest 12-month trailing price-to-sales (P/S) ratio. A low P/S ratio suggests that a stock is undervalued, as investors are willing to pay less per dollar of sales.
