Verify current electrical panel and service line infrastructure is in good condition, compliant with codes, and of sufficient electrical capacity (Amps) to accommodate interconnection of solar power.  Verify position of spare (unused) breaker or space to install new breaker in panel  for solar power interconnection

If a roof installation is planned, verify that the roof will support the installation (e.g., dead load, wind load) and that the current roof covering is less than 5 years old.  Verify that the type of roof is suitable for solar installation (e.g. not slate or wood shingle). The roof understructure shall be inspected and evaluated for support of PV system.  Any reinforcements, such as blocking between rafters, shall be completed before load of PV system is applied

If a roof installation is planned, the roof shall be inspected, cleaned and any necessary repairs shall be made
