NAICS and SET ASIDE INFORMATION: The associated North American Industrial Classification System (NAICS) code for this procurement is 334519 with a small business size standard of 500 employees. This requirement is unrestricted. REQUIREMENT: The National Institute of Standards and Technology requires components to fabricate a custom 2-axis solar tracker. The Energy and Environment Division of NIST has a requirement for the procurement of a semi-customized solar tracker. The solar tracker shall have the basic functionality of a scaled down version of the Sagebrush Technology Inc. Model DA00490 Mobile tracking Platform that is currently in service at NIST. Scaled down means that it is fixed, not mobile, and the size is smaller. To the above Sagebrush baseline model, the solar tracker shall have all of the specifications of CLIN 0001 #1-19 below: ALL INTERESTED VENDORS SHALL PROVIDE A QUOTE FOR THE FOLLOWING: LINE ITEM 0001: Solar Tracker with Components as specified. The requested equipment will be used to create a custom 2-axis precision solar tracker that will be deployed at a fixed location on a building rooftop at NIST. The tracker will be used to test and calibrate multiple solar radiation instruments, solar photovoltaic (PV) cells, and small PV modules. The requested tracker hardware shall include the outdoor 2-axis tracker assembly, all drive motors, and all control components. The requested solar tracker hardware must also meet or exceed the requirements listed below. In describing these requirements, the following definitions apply: A. Equipment Tracking Surface (ETS): the tracker hardware component that is positioned to match the requested equipment elevation and azimuthal angles. The ETS must provide a means for mechanically attaching the Solar Tracking Surface (STS). The ETS is a required element of this procurement request. B. Solar Tracking Surface (STS): a framing that mechanically attaches to the ETS and to which the eventual solar instruments are mounted; the STS will be constructed of rigid aluminum T-slot framing, will be 5 feet wide by 4 feet tall in overall size, and laid out as shown in the below figure. The STS and its mounting hardware are not required items for this procurement request. 1. Capable of continuous 2-axis - azimuthal and elevation - tracking of the sun from dawn to dusk for an entire year when deployed at a north latitude between 30 and 50 degrees. 2. The supplied solar tracker assembly must include an Equipment Tracking Surface ETS) as defined above. 3. The ETS described in Item #2 must permit a means for mechanically fastening and supporting a factory or field-installed Solar Tracking Surface (STS), which is defined above. 4. The tracker must provide absolute positioning of its ETS that is accurate to within ±0.15 degrees in the azimuthal plane and ±0.15 degrees in the elevation plane. 5. The tracker's azimuthal and elevation positions must be provided as feedback variables to the user-written positioning software. The resolution of the feedback azimuthal and elevation positions must each be 0.10 degrees or less. 6. The total system backlash of the solar tracker hardware must be 0.10 degrees or less. 7. The solar tracking hardware must provide the following capabilities with regard to its azimuthal axis movements. a. Total range of rotation: 260 degrees. This azimuthal range of motion must be achievable for all elevation movements covered by Item #8a. b. Drive speed must include the following operating range: 0.25 to 2 degrees per second. A maximum drive speed that is higher than the 2 degrees per second is desired, but not required. c. Loading/torque capacity when the drive operates continuously: 200 foot-pounds (based on a drive speed of 1 degree per second). d. Stiffness of drive: A minimum of 10,000 foot-pounds/radian. 8. The solar tracking hardware must provide the following capabilities with regard to its elevation axis movements a. Total range of movement: from 85 degrees to 180 degrees with respect to the positioning of the STS relative to the horizontal (i.e., the projected normal vector from the STS pointing 5 degrees below the horizon to pointing start up); this elevation range of motion must be achievable for all azimuthal movements covered by Item #7a. b. Drive speed must include the following range: 0.25 to 2 degrees per second. A maximum drive speed that is higher than the 2 degrees per second is favored but not required. c. Loading/torque capacity when the drive operates continuously: 400 foot-pounds (based on a drive speed of 1 degree per second). d. Stiffness of drive: A minimum of 10,000 foot-pounds/radian. 9. The required hardware must include any data acquisition and control (DAC) unit(s) that is needed to (1) read/communicate the position of the ETS, as measured by sensors mounted on the outdoor 2-axis tracking unit, and (2) regulate the motors that position the tracker at the specified azimuthal and elevation coordinates. 10. The required communications and power cabling between the DAC unit(s) and the solar tracker assembly must be provided. This required cabling shall be 25 meters in length if the DAC unit(s) must be located indoors; if the DAC unit(s) is to be deployed outdoors, the manufacturer shall select the appropriate cabling length and provide the appropriate weather-proof enclosure for the DAC unit(s). The required communication cabling between the DAC unit(s) and the NIST-provided Windows-based computer must be provided or clearly described. 11. The solar tracker hardware must be capable of executing the following tracking algorithms over the course of a full daylight period: (1) a zero offset angle from the sun, (2) a fixed offset angle from the sun where the offset is selected based on maintaining the STS at a position that would otherwise be traversed that day if operating with a zero offset angle, (3) a fixed offset angle from the sun while maintaining a fixed elevation angle, (4) a fixed elevation while maintaining a zero offset from the sun in the azimuthal plane and (5) a fixed position. The Windows-compatible control software required to implement these tracking algorithms are not required items but rather optional items (see below). 12. The DAC unit of the solar tracker must be capable of interfacing with a Windows 7 based computer using either the RS485 or RS422 standard protocol. 13. A list of all DAC unit recognizable commands, along with any needed firmware and/or library files, needed to facilitate the two-way communications between the computer and the DAC unit(s) so as to facilitate the above specified two-axis control shall be provided. (Note: the computer shall be provided by NIST.) 14. The tracker hardware must be controllable using Windows 7 compatible software. A list of programming environments that may be used to execute the full command list from Item #13 (e.g., C++ Basic, LabView, etc.) shall be reported. At a minimum, in addition, a simple control program that executes on a Windows 7 computer must be provided that can be used to minimally exercise the tracker hardware. Beyond this minimum, any examples of software written in different programming languages where the DAC unit's recognizable commands are successfully and extensively implemented are favored but not required. 15. The solar tracker hardware must allow continuous deployment outdoors and require minimal periodic maintenance. Any components of the solar tracker system (e.g, DAC unit) that must be located within a conditioned space must be capable of working in a future deployment where the outdoor tracker components are located up to 50 meters away from the indoor components. (Note: cabling shall not be supplied to allow this hypothetical 50 meter maximum spacing; cabling requirements are covered by above Item #10). 16. The solar tracker must be of a design that readily allows for adding a base riser, small truss structure, or an outdoor table - that is provided by NIST - for mounting and anchoring the solar tracker outdoor assembly to a 30"x30"x1" ground level metal plate, such that the centerpoint of the tracker's elevation axis extends 48 inches above this plate. 17. The electrically powered components of the solar tracker hardware must ultimately operate with an input power that is single-phase and nominally supplied at 60 Hz and either 120 or 208 volts. The needed AC power source will be provided by NIST from its building's electrical system. Any electrical converters or inverters needed to power components that require a direct current power source and/or a different voltage input must be provided as part of the solar tracker hardware. 18. No single hardware component of the outdoor portion of the solar tracker must weigh more than 200 pounds. 19. The requested equipment must be delivered to NIST within 120 days of the award date.
