59 -- SPACE FLIGHT SOLAR ARRAY PANELS FOR THE STRV-1C/D SPACERAFT SOL 3-069520 DUE 121197 POC Jon C. Schultz, Contract Specialist, Phone (216) 433-2764, Fax (216) 433-2480, Email Jon.C.Schultz@lerc.nasa.gov WEB: Click here for the latest information about this notice, http://procurement.nasa.gov/EPS/LeRC/date.html#3-069520. E-MAIL: Jon C. Schultz, Jon.C.Schultz@lerc.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; offers are being requested and a written solicitation will not be issued. This notice is being issued as a Request for Offer (RFO) for space flight solar array panels that will provide primary power for the STRV-1C/D spacecraft. Contractors experienced with the fabrication and testing of space-qualified solar array panels are encouraged to respond. Four individual subpanels shall be required. The substrate panels, upon which the photovoltaic cells will be mounted, shall be provided by the Government. Each panel shall be nominally 220 mm x 625 mm. The space-qualified photovoltaic cells, cell interconnects,cell-laydown to the panels,panel wiring, submission of engineering drawings and the thermal-cycling qualification engineering test panels (or required documentation) shall be included in the offer. The substrate panels are 6 mm thick aluminum honeycomb with an aluminum facesheet, covered with Kapton. The cell laydown configuration shall not interfere with the bolt hole patterns on the substrate panels. The engineering drawing detailing usable laydown area can be found at URL http://www.lerc.nasa.gov/WWW/Procure/drawing.htm (Please note: if there is difficulity in using the drawing from the URL please notify the Point of Contact,within 10 days of this posting, and a copy will be faxed). Each subpanel shall provide as much power as possible given the physical limitations and electrical performance of the solar cell used. However, the minimum power of each subpanel shall not be less than 22W, beginning of life, at 25C at 28VDC. The photovoltaic devices shall be gallium arsenide, gallium arsenide-on-germanium, or gallium arsenide-based multijunction cells. Each cell shall have a nominal coverglass thickness of 500 microns. The cells shall be wired to provide a 28VDC bus voltage to the spacecraft. Strings shall be run along the 625mm length of the subpanels to maximize power to the spacecraft. The purpose of the STRV spacecraft is to provide a high-radiation space environment for a variety of experiments. The spacecraft will maintain a geo-transfer orbit. The current of each solar array flight subpanel will be monitored at 28 volts to provide performance data for these panels within this environment. The Contactor shall provide electrical performance data of the flight panels delivered. Otherwise, no environmental testing of the flight panels is required in this offer. Thermal-vacuum and vibration acceptance testing of the panels shall be provided by the Government. Contractors shall provide documentation that demonstrates experience and qualification testing for the exact cell/panel configuration being proposed. Contractors that cannot provide this documentation shall be required to provide engineering panels for thermal-cycling qualification testing. The engineering panel (substrate provided by the Government) shall consist of 1 to 2 strings of 5 to 6 cells each. Proposals providing for only 1,2,or 3 or the flight subpanels described above shall be considered. The provisions and clauses in the RFO are those in effect through FAC 97-01. The SIC code and the small business size standard for this procurement are 3674 and 500 employees respectively. The offeror shall state in their offer their size status for this procurement. All qualified responsible business sources may submit an offer which shall be considered by the agency. Delivery to Lewis Research Center is required within 180 days ofter Contract award. Delivery of the thermal-cycling testing engineering panels or supporting documentation shall be within 60 days of Contract award. Delivery shall be FOB Destination. The DPAS rating for this procurement is DO-C9. Offers for the items(s) described above may be mailed to the identified point of contact at the address specified above by the date/time specified above and include, solicitation number, FOB destination to this Center, proposed delivery schedule, discount/payment terms, warranty duration (if applicable), taxpayer identification number (TIN), identification of any special commercial terms, and be signed by an authorized company representative. Offerors are encouraged to use the Standard Form 1449, Solicitation/Contract/Order for Commercial Items form found at URL: http://procure.arc.nasa.gov/Acq/Standard_Forms/Index.html to submit a offer. Offerors shall provide the information required by FAR 52.212-1.
