House Bill 4/Senate Bill 120: Solar Collector Systems
October 1, 2025
The law currently states that community associations cannot impose unreasonable limitations on an owner who wants to install a solar collector system on their roof or the exterior walls of improvements exclusive to them, which significantly increases the cost or decreases the efficiency of solar installations. However, the term “significantly” was not precisely defined, leading to varied interpretations and enforcement.
The new law sets an objective standard that a restriction is unreasonable if it would increase the cost of the solar collector system installation by at least 5% over the projected cost of the initially proposed installation, or if the restriction would reduce the energy generated by the solar system by at least 10% below the projected energy generation of the initially proposed installation. To show that the community association’s restriction is unreasonable, the owner needs to provide documentation prepared by an independent solar panel design specialist.
Community associations may prohibit or restrict the installation of a solar collector system in the common elements/areas and regulate its size, number, or placement.
