REBATE ELIGIBILITY & RULES
All PV systems must meet requirements listed herein and Public Resource Code Section 25782 to qualify for the PSI:
A. Solar System Size, Location, and Ownership Requirements
Applications with new or expanded sites with no electric bill history or where the existing electric bill does not reflect the customer’s expected expanded consumption, the application must include an estimate of the expected expanded consumption. An engineering estimate is preferred. The engineering estimate must include the appropriate substantiation of the forecast of the customer site’s annual energy use (in kWh) if the generating system size is based on future load growth, including new construction, load growth due to site expansion or other load growth circumstances. Suggested methods of demonstrating load growth include Application for Service with corresponding equipment schedules and single line diagram; building simulation program reports such as eQUEST, EnergyPro, DOE-2, and VisualDOE; or detailed engineering calculations or lists of equipment with corresponding equipment schedules. The PSI Program Manager will verify the load growth predicted before moving forward with the application process. Solar systems installed under previous Solar Program qualify for additional solar capacity under PSI. New application is required and current PSI requirements will apply.
B. Additional Requirements for Third Party Ownership (PPAs) For all customers, except residential, procuring a PV system under a Power Purchase Agreement (PPAs) by Third-Party companies, the Commercial customer PBI rate shall apply (including non-profit customers).
C. Interconnection to the Electric Utility Distribution System Eligible solar electric generating energy systems must be permanently interconnected to the electrical distribution grid of the utility serving the customer’s electrical load. Portable systems are not eligible. The system interconnection must comply with applicable electrical codes and utility interconnection requirements. PV systems will not be allowed to operate until PWP’s Interconnection Agreement and Net Metering Agreement is fully executed (signed) by both customer and the City of Pasadena and written authorization and clearance is provided by PWP.
D. Solar Energy System Components and Warranty All components in the solar energy system must be new and unused and must not have been previously been placed in service in any other location or for any other application. All major solar energy system components, including PV modules, inverters, and meters must be included on the CEC’s Eligible Equipment Lists, which may be found on the Go Solar California website. All solar energy systems must have a minimum 10-year warranty provided in combination by the manufacturer and installer to protect the purchaser against defective workmanship, system or component breakdown, or degradation in electrical output of more than fifteen percent from their originally rated electrical output during the ten-year period.
E. Installation The solar energy system must be installed in conformance with the manufacturer’s specifications and in compliance with all applicable electrical and building code standards. For information about PWP’s rules and regulations for electrical design and installation, please read about Regulation 21. For installations larger than 10 kW AC, rules and regulations governing Regulation 23 (Distributed Generation Interconnection Requirements) may apply. All installations require submittal of electrical drawings such as single line diagram and site plan. Refer to Step 3 of the PSI Application Process for more specific requirements. All installations are required to obtain the appropriate building permits from Department of Planning and Development located at 175 N. Garfield Ave, Pasadena CA 91101. For more information, please call at 626-744-6646 or visit the Permit Center.
F. Utility AC Manual Disconnect
All PV systems shall install a
Utility AC Manual Disconnect with visible break switch contacts
that are lockable in the open position. The purpose of the Utility AC Manual Disconnect is to provide a separation point between PV systems and the Utility Electric Distribution System. The Utility AC Manual Disconnect shall be used to isolate PV systems during operational conditions in order to safeguard Utility personnel. The Utility AC Manual Disconnect shall be installed on the AC Inverter Output Circuit of the PV system and be permanently marked to identify it as a Utility AC Manual Disconnect. The Utility AC Manual Disconnect shall be readily accessible to the Utility at all times and located immediately adjacent to the Customer Service Equipment that functions as the Point of Connection of the PV system. If the location of the AC Manual Disconnect cannot be installed within eight (8) feet from the Customer Service Equipment or Point of Connection of the PV System, its location must be approved at the discretion of the Utility. All questions regarding the location of the Utility AC Manual Disconnect will be directed to the Utility Service Planning Department at (626) 744-4495.
The PSI Program requires accurate energy production meters for all installations that receive PSI Incentives. Accurate measurement of solar energy output is of paramount importance to ensure optimum value for solar owners. PWP requires a performance meter (socket type) in all solar installations. For solar electric generating systems receiving an EPBB Incentive, a basic meter with accuracy of ±5 percent is required. Eligible meters are listed at the Go Solar California website. For systems receiving PBI payments, regardless of system size, are required to purchase performance meter(s) from Pasadena Water and Power’s meter shop. PWP may require additional meter functionality requirements to monitor large solar systems. Meters and service panels must meet all local building and utility codes. PWP will install a bidirectional utility net meter before the system is connected to the grid at no cost to the customer.
H. Maximizing Solar Generation PSI provides financial incentives for high quality solar installations with maximum system performance during periods of peak electric demand. All solar installations are required to submit shading analysis reports generated by a shading analysis tool such as the Solar Pathfinder or the SolmetricEye.
For systems that do not meet the
“Minimum Shading Criteria,” the user is required to input monthly shade
impact results from a shading study conducted at the proposed system
site. These inputs are used as monthly derate factors (100% = no
shading, 0% = total shading) to adjust the PV Watts output for shading.
The shade analysis tool must be specific to the location, azimuth and
tilt of the system being measured and must correct for magnetic
declination. It is the intent of the PSI Program to provide incentives for reliable, permanent, safe systems that are professionally installed, and comply with all applicable federal, state, and local regulations. PWP performsfinal inspection and commissioning for all solar installations in order to verify that the project is 1) installed as represented in the application, 2) operational, 3) interconnected, and 4) conforms to the eligibility criteria of the PSI Program.
I. Energy Efficiency Audits All existing residential and commercial customers are required to have an energy efficiency audit conducted of their existing home or building before solar incentives are paid. Residential customers can fulfill this requirement by providing proof of completing the Home Energy Calculator. They may also schedule a residential energy efficiency audits from PWP at no cost. Please call the Customer Programs Hotline at 626-744-6970. Large commercial customers must contact their PWP Account Manager, who will assist commercial customers to fulfill the audit requirement.
COMMENTS/QUESTIONS If you have any comments, suggestions, or questions regarding the Pasadena Solar Initiative, please call the Customer Programs Hotline at 626-744-6970 or write to solar@cityofpasadena.net
