UNSPSC 40101807: Solar heating units

UNSPSC 40101807 Solar heating units is a Commodity code that state and local governments are using primarily to procure solar photovoltaic (PV) system maintenance, repair, and equipment rather than solar thermal heating systems. Recent solicitations show demand for PV system test, inspection, troubleshooting, repair, and component replacement services; procurement of specific PV equipment such as inverters and power optimizers; and establishment of qualified contractor networks for solar system support. The California Department of Transportation (Caltrans) has emerged as a repeat major buyer, posting three separate IFPQs in April, May 2026 for PV maintenance and repair services across Central, Northern, and Southern California regions, each capped at $484,000 over three-year terms and restricted to certified small businesses, micro businesses, or disabled veteran business enterprises. Other recent solicitations include the City of South Fulton, Georgia issuing an RFP for municipal solar PV standby response and maintenance services (response deadline April 9, 2026), the City of Madison, Wisconsin requesting quotes for SolarEdge inverters and power optimizers (response deadline March 6, 2026), and the Orlando Utilities Commission soliciting contractors for its Preferred Contractor Network including Solar Photovoltaic Systems discipline. State and local buyers across this code span state transportation departments, municipalities, and utility commissions.

Activity concentrates in California, where Caltrans procurements span the state's Central, Northern, and Southern regions across multiple counties; Georgia and Wisconsin also show recent activity. Caltrans requires contractors to hold C-10 (Electrical Contractor) or C-46 (Solar Contractor) licenses from the California Contractors State License Board, prevailing wage compliance on bids exceeding $15,000, and insurance coverage including $1,000,000 general liability per occurrence and $2,000,000 aggregate. The South Fulton procurement requires ten years of verifiable commercial or municipal solar PV experience and offers task order awards with potential for three one-year renewals. The Madison RFQ is a straightforward equipment procurement with local vendor preference scoring available. Caltrans opportunities consistently include set-aside language favoring SB/MB or DVBE vendors, with two price quotes required before award eligibility. Response dates on recent Caltrans IFPQs ranged from April 27 to May 29, 2026; the South Fulton RFP closed April 9, 2026; the Madison equipment RFQ closed March 6, 2026.
