Residential Solar Photovoltaic (PV) Permit in Williams, Arizona
Required for installation of rooftop residential solar photovoltaic systems in Williams. The City publishes a dedicated Solar Policy: solar designs are reviewed by APS (the City's contracted electric-system operator) before the City's Building Department processes the permit and fees, and the City explicitly does not offer a net-metering/billing-credit program.

When you need this permit
- Complete Building Permit Application submitted with solar plans, per the City of Williams Solar Policy
- Solar plans/design must be stamped by a certified electrical engineer or an approved solar design specialist
- Plans are reviewed by APS (the City's contracted operator of its electric distribution system) for approval before the City's Building Department processes the permit and collects fees
- The Solar Policy itself must be signed by the property owner (not just the installer), acknowledging that the City of Williams does NOT participate in any net metering/billing credit program — any electricity produced by the solar system in excess of the owner's use receives no billing credit, and any electricity metered off the City's system is billed accordingly
- The Building Permit itself may be signed by the installer, but the Solar Policy acknowledgment must be signed by the owner
- A schedule of required inspections is noted directly on the issued Building Permit

Tips
- Williams' Solar Policy is unusual among Arizona jurisdictions in explicitly stating the City does NOT offer net metering/billing credits — any solar production exceeding the owner's own use receives no credit, which is a meaningfully different economic proposition than APS-served or net-metering jurisdictions elsewhere in the state.
- The review process routes through APS as the City's contracted electric-system operator BEFORE the City's own Building Department processes the permit and fees — this external-utility review step is a dependency outside the Building Department's direct control and may add lead time beyond the general building-permit average.
- The owner (not necessarily the installer) must personally sign the Solar Policy acknowledgment — confirm this administrative step is completed alongside the permit application itself, since the permit and the policy acknowledgment can be signed by different parties.
