The stock market has seen more than its usual number of dramatic ups and downs in 2020. Following the Covid-19 market crash, U.S. indexes traded up to record highs within months as investors bet on the recovery, with tech leading the pack.

One area of the stock market that did unexpectedly well was clean energy. After solar and renewable utility stocks struggled in recent years, there was undeniably a fair amount of fear that they would fold under the pressure of a weakened economy, especially given the overproduction of oil that has been plaguing the fossil fuel industry and driving down the cost of petroleum products. However, that turned out to be far from reality and many clean energy stocks have exploded off the charts in 2020, providing some of the best returns in the stock market.

The iShares S&P Global Clean Energy Index Fund (ICLN) ETF, an exchange-traded fund that tracks clean energy stocks globally, has a year-to-date return of over 144%, outpacing even the Nasdaq's 43% gain.

One major reason driving the optimism for clean energy is that it is a growth market, as opposed to the already-saturated oil market. Big oil already has the markets flooded, with production so high among competing players that at one point in early 2020, oil producers began running out of places to store the stuff, sometimes even paying more to store it than the price they could sell it for. Meanwhile, nowhere near enough solar and other clean energy projects have been completed to produce even a bit of a global oversupply, leaving plenty of room to grow.

Another reason is that, despite initial worries that the pandemic would end up halting large-scale solar projects and residential sales, the opposite ended up happening. Outdoor working conditions are deemed relatively safe, with Covid-19 finding it a lot more difficult to spread in open air than in enclosed spaces, so outdoor clean energy projects were quickly resumed as planned. In addition, residential solar has boomed alongside the housing industry due to record-low mortgage rates.

With this in mind, here are the five large-scale clean energy stocks that had the highest returns in 2020 while also earning financial strength and profitability rankings of at least 4 out of 10 from GuruFocus, which indicates that even if unfavorable market conditions were to strike, these companies would likely be able to make it through intact.
