What type of restrictions on solar energy systems is considered valid and enforceable?

The validity and enforceability of restrictions on solar energy systems largely depend on whether those restrictions are considered reasonable. Reasonable restrictions allow for the necessary and practical considerations of aesthetics, structural integrity, and community standards while still permitting the installation of solar systems. In this context, roof-mounted systems are often subject to reasonable restrictions that address potential impacts on a building's appearance or the overall neighborhood, as long as these restrictions do not make it impractical for homeowners to utilize solar energy.

This approach aligns with many states' laws and regulations that seek to balance property rights with environmental considerations, thereby ensuring that homeowners can still access solar energy without facing undue barriers.

In contrast, restrictions that are overly broad or completely prohibitive, such as those preventing any solar installations or imposing unreasonable limitations, conflict with the growing trend to encourage renewable energy use and are likely unenforceable. Moreover, restrictions without any exceptions would be seen as overly restrictive and, therefore, invalid. Thus, reasonable restrictions on the installation of roof-mounted solar systems represent a balanced approach that maintains the integrity of property rights while facilitating the integration of renewable energy solutions.
