My HOA doesn't allow it or I'd have them already. And there is no way to fix this because the way the HOA is set up, it is impossible to get a quorum to change it.
Assuming you're in the US due to the relative popularity of HOAs there, this has thankfully been blocked in some (particularly sunny) states. At least California, Texas, Florida, and a few others have solar access laws that prohibit HOA restrictions on solar panel installations. It's worth making sure your state doesn't have a similar policy.
