NIGP 29010: Cells, Solar (Photovoltaic Cells), Unmounted

NIGP 29010 Cells, Solar (Photovoltaic Cells), Unmounted is an Item code under which state and local governments procure solar photovoltaic equipment and components—primarily inverters, optimizers, mounting systems, and complete solar arrays—as part of larger capital projects and ongoing maintenance contracts for municipal facilities, water infrastructure, and renewable energy initiatives. Recent solicitations show state and local buyers purchasing solar equipment through design-build RFPs, equipment-supply RFQs, comprehensive EPC (Engineering, Procurement, and Construction) contracts, and indefinite-delivery maintenance agreements. The issuing-body mix spans county departments (Boulder County Parks, Fayette County, Okaloosa County Emergency Management, Cobb County Facilities), municipal engineering departments (City of Madison), city sustainability programs (City of Dallas, City of Bartow, City of South Fulton, City of New London), state agencies (South Dakota Department of the Military), and multi-county cooperative purchasing vehicles (Sustainable Energy Partnership in Pennsylvania). Counties and municipalities appear to dominate activity, with most posting individual solar projects ranging from 22 kilowatts to 1.78 megawatts in capacity rather than routine commodity buys.

Recent opportunities cluster in the Southeast and Mid-Atlantic (Georgia, Florida, Connecticut, Pennsylvania) and Mountain West (Colorado, South Dakota, Wisconsin), reflecting state renewable-energy mandates and federal Inflation Reduction Act incentives driving municipal solar deployment. Representative recent solicitations include Boulder County Parks and Open Space RFP30026 (installation of four and two stock-water wells with solar pumps on agricultural leases, due September 4, 2026; $350,000 contract value); the Sustainable Energy Partnership ITB 6599 (design, procurement, and installation of 14 solar projects across four Pennsylvania counties ranging 22.82 kilowatts to 1.78 megawatts, due May 21, 2026); City of Dallas BT2600030442 (three-year ID/IQ maintenance and repair agreement for solar panels and equipment, due July 17, 2026); South Dakota Department of the Military design-build RFP CFMO# 466410 (200-kilowatt solar array installation at Mitchell Combined Support Maintenance Shop, proposals due April 2, 2026); and City of Madison RFQ 5506-0-2026-AH (SolarEdge photovoltaic inverters and optimizers, due March 6, 2026). Prevailing-wage, apprenticeship, Build America Buy America, and domestic-content compliance requirements appear consistently in design-build and EPC solicitations over $1 million; performance and payment bonds are standard for contracts exceeding $50,000 to $100,000.
