No word in this report about the specific of the virus being blamed.
Adjustments following the 2016 solar boom, angst surrounding the Section 201 Trade Case, and a slowdown in established solar markets all contributed to an overarching 3.8 percent cutback in solar jobs over the past year, according to The Solar Foundation's latest National Solar Jobs Census. Between 2016 and 2017 the industry lost 9,800 jobs
On a brighter note, the solar industry's diversity numbers aren't as bad as some other energy sectors:
Compared to the overall U.S. workforce, the solar industry has about half as many Black employees and 20 percent less women. The industry has higher numbers of Latino, Hispanic, and Asian employees.
The Solar Foundation notes that “solar is also more racially and gender diverse than comparable energy sectors, such as coal and oil and gas extraction."
