In Texas, your HOA is allowed to restrict your solar panel installation, but only under adverse conditions.
Texas law does allow HOAs to restrict solar panels if one of the following conditions exist:
- If the solar energy devices are illegal or violate public health and safety
- If they are located on common property within the subdivision
- If they extend higher than the roofline, do not conform to the slope of the roof, or are not parallel to the roofline
- If they are ground-mounted and extend above the homeowner’s fence
- If they are installed in a way that voids the warranties
- If they have an element that is not in a silver, bronze, or black tone
- If they are installed without prior approval by the HOA
Your HOA can also designate placement of solar panels, but not if the change from your original plan results in a drop of 10% or more in efficiency.
