Can my HOA require solar panels only on the back of my house?

What if my HOA refuses to approve my solar installation?
The HOA must decide within 45 days of a complete application; failure to act means automatic approval. If they deny improperly, you may sue for up to $1,000 plus actual damages and attorneys' fees.
