How do I report scam ads (solar panels scam)? [Translated FR -> EN]

I would like to report an ad pretending to be an official french government site to scam people at around 25000 to 30000 € according to Trustpilot users. “France Eco Infos”, a fake news website, is linked to this scam.

Here’s an exmaple of their ads (translation after this image):

France Eco News

No need to buy solar panels – try this instead (it’s brilliant)

How do I report it or if it’s not possible can you report it ?
