Could you kindly provide clarification on this matter? Power one Aurora Universal Commercial

Can you provide information on the current wattage? 210 kW (DC)

What types of panels and inverters are currently installed? Kyocera Model KD-240 Watt modules and Power One Aurora Photovoltaic Inverters (PVI 10/12-I-OUTD-

US/CAN)

Are there any plans for removing or replacing existing equipment? No

Is the system owned outright or under a lease? System is owned

Could you please share the age of the system? 10 years old

Will there be a site-visit for this acquisition? No

Are we tasked with replacing solar panels or upgrading the monitoring system? Replacement of solar panel monitoring system What is the current wattage of the system? 240 Watt

Could you provide details on the specific panels and inverters being used? Kyocera Model KD-240 Watt modules and Power One Aurora Photovoltaic Inverters (PVI 10/12-I-

OUTD-US/CAN)

Will there be any components that need to be removed or replaced? Johnson Control Module connected to Aurora Universal to sent PV data to existing JC Metasys system needs to be replaced.

Is the system owned or leased? System is owned

How old is the current setup? 10 years old

We require copies of utility bills and access to Green Button data for all meters we aim to offset.

Based on the information available, it is not clear that the removal of the existing monitoring system and installation of a new PEV monitoring system will require a new inverter. Kindly confirm.

VA doesn’t understand the need for you to access the utility bills and we don’t have Green Button Data. The scope of work for this solicitation does not require the installation of a new inverter only a new monitoring system.

If not brand new, could you please provide the current / previous contract number? What contract are you referring to?

Can we attain the as-built dwgs prior to a site visit and prior to responding to this RFQ? Yes As built drawings will be provided as attachment in an addendum to the solicitation

The solicitation indicates an SLA (service agreement) must be in play. How long does this need to be in play and how do we quote this portion relative to annual or monthly costing? Cole can you answer this question

Are there any pictures available for this project? As built drawings and O&M Manual will be provided as attachment in an addendum to the solicitation

Please provide any as-built drawings, product data sheets, O&M manuals, specification, etc. of the existing solar photovoltaic system, specifically the monitoring system to be replaced.

Please share any available information such as utility bills for last 12 months, interval data, pictures of the system. VASDHS will not provide the utility bills. As built drawings and O&M Manual will be provided as attachment in an addendum to the solicitation

Is there a fiber optic connection at the location? Yes Does the local telephone company services it? No Page 4 of the Solicitation indicates CLIN 0001 (Labor/Parts/Materials/ for Solar PEV Monitoring System) under ‘B.2. PRICE/COST SCHEDULE’. Page 27 indicates the requirement for ‘Unscheduled Maintenance (Emergency Repair Services)’. Should there be a CLIN covering this requirement (e.g. per each request for unscheduled maintenance)? No The installation should have the standard 1 year warranty

Also, how long (e.g. 1-year, multi-year) should we assume? See answer above

Does this Solicitation cover the monitoring replacement only? Solicitation covers only the replacement of the monitoring system.

Is any work regarding the rest of the system such as the solar panels, roof, any storage batteries, etc. to be excluded? Yes

May we know if the existing solar PV system is still under warranty? No

Is there a magnitude and Period of Performance for this Solicitation?

What make and model is the existing system that is being replaced? Kyocera Model KD-240 Watt modules and Power One Aurora Photovoltaic Inverters (PVI 10/12-I-OUTD-

US/CAN)

Does the new PEV monitoring system need to integrate to an existing, onsite product? If yes, what system is currently used by VASDHS? This is to be an independent system.

What level of monitoring is to be performed (inverter or panel level)? Panel level. The monitoring system is to report the amount of electrical power being produced by the Roof Top PEV panels in total.

Can the system be brought offline during installation of the new monitoring system? Yes.

Who installed the current monitoring system and who was the manufacturer. How much did the installation cost from previous contractor? Baker Electric installed the system. Kyocera Model KD-240 Watt modules and Power One Aurora Photovoltaic Inverters (PVI 10/12-I-OUTD-US/CAN). The VA does not understand the need to provide the installation cost of the PV system for this procurement.

Who monitored the system and how did they receive the data, what is the existing network: Wi- Fi, Cellular, or hardwired? Was it a web-based service? The VA Central Plant located in Building is the monitoring point for this system. The existing system is a hard wire system on an existing network.

What is the monitoring system doing, currently? The current monitoring system is non operational and does not report to the existing Johnson Control Metasys System.

Is the PV system generating or stopped due to monitoring service issues? PV is generating Is the production unknown due to monitoring service issues? Yes
