NIGP 29040: Solar Heat Collector Systems and Accessories

NIGP 29040 Solar Heat Collector Systems and Accessories, an Item code, covers the procurement of solar photovoltaic and thermal systems, inverters, optimizers, and related equipment and services that state and local governments integrate into municipal energy infrastructure. The code encompasses both capital procurement—specific equipment such as inverters and power optimizers—and comprehensive solar energy services spanning design, installation, maintenance, and decommissioning. Issuing bodies under this code include city engineering departments, county governments, municipal utilities, and special-purpose districts. Recent solicitations show cities and counties pursuing solar deployments as standalone capital projects or as elements of broader sustainability initiatives, with work ranging from equipment procurement to full lifecycle system management including 24/7 standby response and performance monitoring.

Geographic activity is concentrated in the Southeast, with recent opportunities posted by the City of South Fulton and Fayette County, Georgia; the City of Lubbock, Texas; the City of Madison, Wisconsin; and the Orlando Utilities Commission in Florida. The City of South Fulton issued RFP 26_09 in March 2026 for solar PV standby response and maintenance services with proposals due April 9, 2026, requiring ten years of verifiable commercial or municipal solar PV installation experience and 24/7 emergency response capability with tiered response times. Fayette County, Georgia solicited RFP #26087-P in February 2026 for a comprehensive Solar Energy Initiative encompassing evaluation, design, installation, maintenance, operation, and decommissioning, with proposals due March 17, 2026.
