Largely no — California Civil Code 714 (Solar Rights Act) limits HOA restrictions. They may require aesthetic compromises but cannot make solar economically infeasible.
Lancaster FAQ

Yes. The Zero Net Energy Home Ordinance (effective Jan 1, 2018) requires new single-family homes to have a solar system equivalent to 2 watts per square foot of conditioned floor area, or pay a mitigation fee in lieu.
