NIGP 29086: Solar Radiant Flux Measuring Instruments (see Also 220-33)

NIGP 29086 Solar Radiant Flux Measuring Instruments is an Item code that encompasses measurement and testing equipment for solar energy systems, though recent state and local procurement activity shows practical focus on solar installation and performance verification rather than standalone flux measurement devices. State and local bodies procuring under this code are typically municipalities and special-purpose districts managing renewable energy infrastructure projects. The City of Tybee Island, Georgia exemplifies the issuing body profile — a smaller municipality undertaking capital-level solar deployment on public facilities.

The City of Tybee Island, Georgia posted RFP2026-113 on October 3, 2026, seeking proposals for a 42-kilowatt minimum solar array installation on the Tybee Island Marine Science Center, with sealed proposals due November 3, 2026 at 12:00 p.m. The scope specifies Q-Cell solar panels manufactured in the United States, rated at minimum 400 watts per panel, UL-certified equipment, SMA Sunny Boy string inverters, and GAF certification for TPO roof integration. A pre-proposal meeting and site visit were held on October 13, 2026. The evaluation emphasizes reference quality (40 points), specification compliance (20 points), and installation schedule (15 points), with cost weighted at 10 points and RFP compliance at 15 points. The contractor must secure federal, state, and local approvals, provide a one-year warranty, and submit a lump sum cost proposal. Activity under this code remains sparse in recent state and local solicitations.
