Customer or contractor submits the PV Interconnection Application (+ Energy Storage optional) via PowerClerk and uploads the following supporting documents:

a) Signed Interconnection Agreement (IA). Click here for the Net Energy Metering Resolution. The proposed system size should primarily be intended to offset part or all of the customer's own electrical requirements. GWP uses 110% of the customer's kWh usage of the past 12 months to establish the customer's anticipated annual load.

i) In Case of PV systems sized up to 10 kW CEC-AC, self-certification of system size need will be required within the PV Interconnection Application on PowerClerk. 

ii) In case of PV system over 10 kW CEC-AC, GWP uses 110 % of the customer's kWh usage of the past 12 months to establish the customer's anticipated annual load. This kWh figure is compared to the estimated production of the proposed PV system. The estimated production of the PC system is calculated by PowerClerk. 

b) Executed Election Form.

c) Site Diagram showing the physical location of the significant electrical components of the Generating Facility (+ Energy Storage optional) such as modules, inverters, transformers, and control panels, the Customer's loads and the interconnections with GWP's Distribution System Diagram that must show the approximate location of all major electric components.

d) One Line Diagram showing the electrical relationship and descriptions of the significant electrical components such as the metering equipment, panel boards, solar panels, inverter(s), AC Disconnect(s), solar meter, circuit breakers, and Energy Storage equipment (if applicable), with operating voltages, capacities, and protective functions of the Generating Facility. For GWP’s photovoltaic requirements, see Distributed Energy Resources Section of the Electrical Service Requirements Manual. GWP will only approve one-line diagrams that follow one of the approved DERS diagrams in the Distributed Energy Resources section. For additional information, please contact GWP engineering at 88-548-3921.

e) Data Sheets for solar panels and inverter.

 f) Shading analysis report  this requirement may be waived on the condition that a copy of a disclosure statement is provided to the customer and program administrator that identifies existing trees on the site and adjoining sites that are smaller than 50 feet, which may cast potential future shade that would reduce future system performance.

g) Photograph of the location where the required PV meter will be installed. Photograph should include the wall, entire surrounding area, and all applicable clearances; including the 3' x 3' working space in front of the solar meter and disconnect. A photograph of the existing main service panel. 

h) Data Sheet for Energy Storage Device and switch/relay (if installing)

GWP Solar Team reviews and forwards the application packet to GWP Engineering.

Solar contractor contacts GWP at 818-548-3921 to request a DG Service Spot (drawing of utility approved location for solar meter and AC disconnect). 

GWP Engineering staff visits property and creates a DG Service Spot drawing. Please contact GWP Engineering at 818-548-3921 for the latest estimate of the turnaround.

In the meantime, GWP Engineering forwards the Interconnection Agreement to the General Manager for approval.

After the Interconnection Agreement is approved, GWP Engineering emails the DG Service Spot drawing to the solar contractor with instructions for submitting plans for permitting.

GWP Engineering forwards the approved Interconnection Agreement to the GWP Solar Team.

GWP Solar Team uploads the IA to PowerClerk.

Solar contractor incorporates the DG Service Spot drawing and photograph into the solar plans and ensures that their solar plans are consistent with GWP’s DG Service Spot drawing.

Solar contractor emails the entire set of solar plans for permitting and to the GWP Engineering at GWPEngDG@glendaleca.gov

GWP Engineering approves the solar plans and emails the approved plans to the solar contractor. Contractor applies for solar permits at GlendalePermits.org. If the project is upgrading Main Service Panels, a separate electrical permit is required. 

Once the Full Plan set is submitted by the contractor via the Glendale Permits portal, Building and Safety reviews the solar plans and contacts the solar contractor for payment of fees, issuance of permit, etc. For information regarding the permit process and requirements, please contact Building and Safety at (818) 548-3200.

Building, Electrical and Fire review and approve the plans. Allow 2 - 4 weeks for this review.

The Solar Energy Permit is issued by Building & Safety and sent to solar contractor via email.

Solar contractor installs solar system.

Solar contractor uses their Glendale Permits account to schedule their inspection with Building & Safety. If the solar system is for a commercial property or includes an Energy Storage system, the solar contractor contacts GWP Engineering for an inspection by calling 818-548-3921.

After the inspection and final sign-off, Building & Safety notifies GWP Engineering that the solar system passed inspection.

Upon receipt of inspection releases, GWP Engineering submits a work order to GWP Field Services for the installation of the solar meter. (7-10 working days, Fridays and weekends excluded).

Once the solar meter is installed, GWP Solar Team changes the status of the project to “PV PTO Issued” and sends an email to the solar contractor and the customer notifying that the solar meter has been installed and the system can be turned on by the solar contractor or property owner. This e-mail also has the approved Interconnection Agreement attached.
