( ii ) Air source heat pumps.

( iii ) Ground source heat pumps.

( iv ) Insulation.

( v ) Rain barrels.

( vi ) Reflective roofing.

( vii ) Energy efficient appliances.

( viii ) Solar water heaters.

( ix ) Electric vehicle supply equipment.

( x ) Energy-efficient windows.

( xi ) Energy-efficient insulation materials.

(d) "Local unit of government" means a county, township, city, or village.

(e) "Member" means an owner of a home or unit that is within the jurisdiction of the homeowners' association.

(f) "Policy" means the written solar energy policy statement described under section 9(1).

(h) "Solar collector" means any of the following:

( i ) An assembly, a structure, or a design, including passive elements, used for gathering, concentrating, or absorbing direct and indirect solar energy, or specially designed for holding a substantial amount of useful thermal energy, that transfers that energy to gas, solid, or liquid or uses that energy directly.

( ii ) A mechanism that absorbs solar energy and converts it into electricity.

( iii ) A mechanism or process used for gathering solar energy through wind or thermal gradients.

( iv ) A component used to transfer thermal energy to a gas, solid, or liquid or convert thermal energy into electricity.
