Although the transition to clean energy is anticipated to keep the green energy sector afloat, solar energy, which witnessed significant headwinds in 2022, could face further challenges amid declining installations and soaring supply chain stress.

Given this backdrop, fundamentally weak green solar energy stocks Sunrun Inc. (RUN), Polar Power, Inc. (POLA), and Ascent Solar Technologies, Inc. (ASTI) could be best avoided now for reasons mentioned in the article.

To meet the net-zero emission goals, investment in alternative energy has been on the rise, and the importance of the solar industry has also been growing. However, like other industries last year, the solar energy industry was not out of the grasp of the plethora of headwinds.

According to the U.S. Solar Market Insight 2022 Year in Review by the Solar Energy Industries Association (SEIA) and Wood Mackenzie, utility-scale installations fell by 31% year-over-year to 11.8 GW, posting the sector’s lowest total since before the COVID-19 pandemic.

Moreover, amid momentum escalating to impose steep tariffs on Chinese components have alarmed the U.S. solar industry, homeowners hoping to add solar panels to their roofs, motorists wanting to charge electric vehicles with clean power, and utilities trying to reduce their carbon footprints.

Furthermore, according to Michelle Davis, lead distributed solar analyst at Wood Mackenzie, the solar industry faces a significant amount of uncertainty in the year ahead, more than the usual uncertainty about the future.

Much of whether the industry rebounds in the latter half of 2023 depends on what happens to supply chain disruptions created by the Uyghur Act. 

Against this backdrop, it would be wise to avoid green stocks RUN, POLA, and ASTI, with bleak prospects now.
