The State (who is the owner) intends to contract for solar PV systems to be installed on parking lot canopy structures and Battery Energy Storage Systems (BESS) that are interconnected with the local utility (Evergy) grid on three (3) of the campus buildings. There are existing Standby generators at each building that will need to operate alongside the PV and BESS. In the event of an outage, the grid relay will need to open and a microgrid will need to be formed. Load demand will be met by PV and ESS. The generator will turn on/off depending on the programmed battery SOC thresholds. In most operating modes, when the grid returns the generator will be shut down via a two wire start command. When the inverter senses the grid return, the grid relay will close, and the system will return to normal operation.: 1. Plans have a list of accounts and addresses of the (3) buildings and their basis of design. 2. The systems will tie into the respective building's electrical system with the intent of entering into either a Net Metered or Parallel Generation agreement with Evergy, depending on the cost-benefit. Installations of this project will begin after a City Purchase order is issued. B. Pre-Install 1. Submit system design to utility company for approval of Net Metering and/or Parallel Generation. Interconnection application submitted to utility company. 2. All project permits filed and submitted (Who would the AHJ be) 3. Installation scheduled with client C. Installation 1. Install 2. System test performed for proper function. 3. Inspections scheduled if needed 4. Submit necessary documentation to utility company D. Post-Installation 1. Utility company inspection integrations 2. Contractor completes final system checks, energizes system, and provides operational walk-thru with clients 3. Contractor provides system monitoring and alerts training, and documentation. E. Specifications: 1. The Solar PV System. The Solar PV system will be rated the size in kW direct current. Solar Panels selected must be Tier 1 panels and be certified to meet UL 61730. ZNShine 585W bifacial double glass monocrystalline PV modules were used as the basis of design. Hybrid Inverters must be Sol-Ark 30K-3P-208V and Sol-Ark 60K-3P-480V. o Building 670: 64.35 kW DC, 60 kW AC, Load Ratio 1.07, (110) 585W panel & (2) Sol-Ark 30K-3P-208V o Building 2003: 155.025 kW DC, 120 kW AC, Load Ratio 1.29, (265) 585W panel & (4) Sol-Ark 30K-3P-208V o Building 2005: 286.65 kW DC, 240 kW AC, Load Ratio 1.19, (490) 585W panel & (4) Sol-Ark 60K-3P-480V 2. The Battery Energy Storage System. The BESS will be rated in kWh nameplate energy capacity. Battery cell chemistry must be Lithium Iron Phosphate. It must be able to communicate with the Sol-Ark Hybrid inverters and have an integrated control system, transfer relays, AC/DC coupling, built-in fire suppression, temperature controlled outdoor rated cabinet and certified to meet UL1973, UL9540, UL9540a, UN38.3, FCC, Prop 65. Sol-Ark L3 Series LimitLess Lithium BESS was used as the basis of design. o Building 670: 245.76 kWh, (4) L3 HVR-60KWH-30K o Building 2003: 491.52 kWh, (8) L3 HVR-60KWH-30K o Building 2005: 737.28 kWh, (12) L3 HVR-60KWH-60K 3. The Solar Canopy System. The solar panel installation shall include all necessary solar panel mounting and protection equipment as required. It must cover the parking spaces as indicated in Attachment XXXX. It must be designed and engineered to meet Risk Category IV criteria, with a minimum clearance height of 12 feet. It must also include gutters and downspouts, snowguards, and 70-75W outdoor rated LED canopy lighting. 4. The Electrical System. The electrical service that the inverter(s) will back feed and support will have adequate space for the inverter interface circuit breaker(s), CTs, and Controls. The electrical service panel bus bar rating will not be exceeded beyond what the National Electric Code allows. The building's electrical service panel complies with all local electrical codes. A utility accessible disconnect will be installed near the service entrance. If the BESS is within 150 feet if the building, a blast wall will need to be constructed to protect the building. 5. The Monitoring System. Contractor will provide a monitoring system, available to the State through the State's own internet connection or access. Monitoring system will include a HMI dashboard as well as future integration with BAS via Modbus interface. 6. Installation. Contractor will comply with OSHA requirements for job site safety and all materials and trash will be removed from the job site once work is completed. 7. Experience: The State is seeking contractors with a minimum of 10 years direct experience designing & installing commercial rooftop solar PV systems of similar scope and capacity. 8. Minimum Warranty: The State prefers, at a minimum, a 2-year workmanship warranty, 30-year solar panel output warranty, 12-year solar panel product warranty, 10-year inverter warranty, 10-year BESS warranty, XX-year canopy warranty.
