Enphase

Site access is provided (site owner designation not recommended until M2)

Current transformers )CTs) installed correctly based on manufacture requirements.

Cell kits and Revenue Grade Metering (RGM) are required on all projects. If equipment is placed indoors and the signal is weak, a cellular signal booster may be required. If cellular service is unavailable for the area, a wireless gateway or ethernet connection is required to establish remote monitoring (uncommon scenario).

A2 permits

Approved permit is provided Status must be APPROVED/ISSUED

Scope of the permit is for the solar PV install

Address matches installation site

(D) Design package Documents

D1 Planset

System size & module count match vs what was installed

Module manufacturer & wattage match what was installed on site

Inverter, racking, & all other components match what was installed on site

Planset is accurate (within tolerance) vs what was installed on site (Tilt, azimuth, etc)

All equipment on approved vendor list

D2 Production Model

Approved platform Aurora

Approved inputs & system loss settings

Design on the production model is accurate (within tolerance) vs what was installed on site

1) Production Model Confirmation that the Inputs were set properly by the user: Production Engine Weather Dataset System Losses etc.

2) Shading Report Confirmation that Shading was properly modeled: LiDAR/DSM Overlay Irradiance Overlay

3) Plan Set Required pages of the Engineering Plan Set submitted to the building department: Pertinent site details (Name, Address, etc) Site Plan (Tilt, Azimuth, Module layout, etc) One Line/Three Line Engineering stamps + structural calculations as needed Equipment is on LightReach AVL Spec sheets for equipment used on site. Plans demonstrate that components are installed to manufacturer specs (IE string or branch circuit lengths for inverters, min/max overcurrent amperage limits, etc)
