Solarready

Solarready refers to buildings designed and constructed to accommodate solar energy systems with minimal additional work. The goal is to enable efficient later installation of photovoltaic (PV) or solar thermal equipment by providing appropriate electrical infrastructure, roof space, and structural considerations at the outset.

Typical solarready features include a pre-planned conduit pathway from the main electrical panel to the roof or attic, space inside the panel for PV backfed breakers, and a designated roof area with unobstructed sun exposure. In some designs, an exterior disconnect, a dedicated meter socket, or a pull box may be installed to simplify interconnection. Structural assessments may confirm roof framing and attic clearance sufficient for mounting and wiring.

Solar readiness is addressed differently by codes and programs around the world. In the United States, some jurisdictions require solar-ready provisions as part of building or energy codes, codes such as the NEC, and various municipal incentives; other areas treat it as a voluntary design option. Standard guidance is provided by industry groups and code bodies rather than a single universal standard.

The advantages of solar-ready construction include reduced future installation time and cost, smoother permitting, and potential resale value. Limitations include the fact that readiness does not guarantee suitability for solar; site shading, roof condition, interconnection requirements, and equipment choices ultimately determine feasibility and cost.
