SLD Reqs

Meter Orientation = Over/Under


  • Ubill holder must be listed on the SLD
  • Inv to the top of PM, bottom of PM to AC Disco > MSP > bottom of UM.
  • Utility will install one Production Meter (PM) and one Utility Bidirectional Meter (UM).
  • Existing and new solar installations must be metered by the same PM.
  • .pdf" in Files section of this page.
  • The breaker rating specified on the SLD must match the installed breaker.
  • Show sizing table for wires between AC Disconnect and PM, and between PM and MSP.
  • Load calcs required on all projects
  • Section 230.67 of the new 2020 NEC requires the installation of a surge-protective device (SPD) for all dwelling unit service entrances. New and replaced electrical equipment and systems must incorporate Type 1 or Type 2 SPDs. Type 1 surge protective devices can be installed before the main disconnect in the load center, at the meter enclosure or on the load side of the main circuit breaker. Type 2 surge protective devices can only be installed on the load side of the main disconnect, attached directly to a circuit breaker. Often, new construction will install Type 1 surge protectors, while renovations will install Type 2 surge protectors, but both types will satisfy the new requirements.
  • As of July 1, 2021, this state uses the 2020 NEC..

Existing Systems

  • Existing and new solar installations must be metered by the same PM.
  • The one-line MUST show how much the current system is producing and how much the addition will produce as well as the total expected annual production.  
  • The one-line MUST show the sizes in AC and DC for both, existing and additional equipment. ie. Existing: 1x Solar Edge SE3000= 3.0 kW AC, 10 X 300w Panasonic X = 3.0 kW DC, NEW: 1X Solar Edge SE3000...  
  • Show kW-DC size of existing, new and combined systems..
Electric Service Reqs
  • If existing meter is to be opened (Line tap or MBE), existing meter must be rated for 200A or more
  • Must have 3ft clearance in from of main panel, we will need to relocate
  • /\ /\ If existing UG service, we will need a meter spot to grandfather existing location
  • Bubble meters not permitted, must upgrade if existing bubble meter or under 100A service



  • Electrical Review Team \/ \/ \/ \/
  • Meter needs to be 80ft or closer from utility pole (if closest point on home is not within 80ft, we need a utility engineer to give the okay on the service drop distance to be left as is or may be required to install a meter pole closer to their utility pole)
  • Meter cannot be under a porch nor service line crossing a roof less than 8ft in height (service line to roof) or 4ft in length
  • Weatherhead is to be 36 inches from roofline
  • Middle of meter bubble must be minimum 4ft, max 5ft 6inches
  • No embedded meters allowed (if opening meter, would need to bring this out)
  • In the event that there is a tree in the path of where the service line will be running through (overhead), this will need to be trimmed prior to the utility energizing the MPU

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with El Paso Electric (NM) before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
