When Building a New Home or ADU, Roof Design Matters for Solar

Roof layout, orientation, and usable surface area can determine whether solar is easy, expensive, or barely possible.

When planning a new home or ADU, roof design has a direct effect on solar potential. Roofs that are split into many small sections often lose too much usable space once setbacks are applied.

Large, simple roof planes are usually easier to use efficiently. Orientation, geometry, and available contiguous area all shape the system size that can fit later.

That is why solar thinking should start during the building design phase, not after construction is already set. A better roof today can mean a far better energy plan tomorrow.
