It’s still somewhat of an investment though, no? Generating your own electricity rather than buying on from someone else.

Maybe I read it wrong but it looks like the business owners pay for it and the energy goes to the public?

It’d make more sense for the power to go to that particular business and then have the energy company buy the surplus to power homes.

I don’t have solar but my energy company has an opt-in program where they buy any excess energy, or all of the energy you generate.

If the energy companies are going to buy excess energy in France then it could be somewhat of an investment for those businesses.
