NIGP 29090: Solar Water Heating Systems and Accessories

NIGP 29090 Solar Water Heating Systems And Accessories is an Item code covering the supply, installation, and servicing of solar thermal and photovoltaic systems for state and local facilities. Recent opportunities show municipalities soliciting full turnkey solar array installations with specified equipment requirements, manufacturer certifications, and warranty provisions. State and local governments buy under this code to retrofit public buildings with renewable energy capacity, reduce operational utility costs, and meet sustainability mandates. Issuing bodies include cities and counties across various scales and geographies. The scope extends beyond solar water heating to encompass broader solar power generation systems integrated into municipal facilities, with performance specifications tied to building infrastructure compatibility and regulatory compliance.

The City of Tybee Island, Georgia posted RFP2026-113 on October 3, 2026, seeking proposals for a 42 kilowatt minimum solar array installation at the Tybee Island Marine Science Center, with sealed proposals due November 3, 2026 and a pre-proposal meeting and site visit scheduled for October 13, 2026. The solicitation specifies Q-Cell solar panels manufactured in the United States rated at minimum 400 watts per panel, SMA Sunny Boy string inverters, GAF certification for roof system compatibility, and a one-year warranty on all components, with evaluation criteria weighted toward reference quality (40 points), specification compliance (20 points), installation schedule (15 points), RFP adherence (15 points), and cost (10 points). Broward County, Florida issued a Request for Information on September 18, 2026 (due September 29, 2026) regarding DeZurik/APCO valves and repair services for wastewater treatment facilities, which while focused on valve control systems rather than solar thermal equipment, demonstrates county-level procurement of specialized utility infrastructure components. Recent activity concentrates in the Southeast; the mix of issuing bodies spans municipalities and county utilities addressing facility modernization and regulatory compliance objectives.
