THURSDAY, June 25, 2020 (HealthDay News) – Here’s some really sunny news from the coronavirus pandemic.
Lower air pollution from people staying at home has allowed more sunlight to reach solar panels and increased their clean energy performance.
For the study, the researchers analyzed data from Delhi, India, one of the most polluted cities in the world, and published their results in the journal on June 19 Joule.
“India initiated a drastic and sudden blockade at the beginning of the pandemic,” said the study’s first author, Ian Marius Peters, from the Helmholtz Institute Erlangen-Nuremberg for renewable energies in Germany. “This means that air pollution has been reduced very suddenly, making it easier to spot.”
At the end of March, the amount of sunlight reaching the solar panels in Delhi increased by around 8% compared to 2017, 2018 and 2019, investigators found.
Data on air quality and particle pollution suggest that, according to the researchers, lower levels of pollution were a major reason for the increase.
“The increase we saw is the difference between what a [solar panel] in Houston would produce compared to one in Toronto, “said Peters.” I was expecting to see a difference, but I was surprised at how clearly the effect was visible. “
Together with previous research from other cities, the Delhi results provide a good basis for further studies on how air pollution affects solar power generation, the authors said in a press release.
“We got an idea of what a world with better air looks like and we see that there is an opportunity to smooth the climate curve,” said Peters. “I believe that solar panels can play an important role and that this will be more in the future [solar energy] Installations could help create a positive feedback loop that leads to a clearer and cleaner sky. “
