UNSPSC 41114407: Solar radiation surface observing apparatus

UNSPSC 41114407 Solar radiation surface observing apparatus is a Commodity code that in recent state and local practice encompasses lightning detection, prediction, and protection systems, along with associated weather monitoring hardware and instrumentation. The code shows a significant disconnect between its nominal description and actual procurement activity: state and local buyers are using it to acquire lightning protection installation services, lightning detection and severe weather monitoring systems (including Sferic Weather Stations and alert technologies), and related sensor and detection hardware rather than solar radiation measurement equipment. Issuing bodies span state agencies, county governments, and cities. The Texas Military Department issued an IFB for lightning protection system installation at military facilities; Hillsborough County pursued a sole-source procurement for Earth Networks lightning detection and severe weather monitoring hardware, software, and maintenance; the Texas Water Development Board solicited temperature sensors and pyranometers (which measure solar radiation and are tangentially related to atmospheric monitoring); and Broward County and the City of Fort Lauderdale jointly issued an RFI regarding a Thor Guard lightning prediction and detection system upgrade at parks and the county airport. The mix suggests that this code has been applied to weather-monitoring and lightning-safety infrastructure rather than pure solar radiation measurement.

Recent activity concentrates in Texas and Florida. The Texas Military Department's IFB TMD26-FMO-0044558 for lightning protection system installation at Camp Swift in Bastrop closed September 26, 2026, with a mandatory pre-bid site visit on September 16, 2026; the scope covered installation at eight sites with one-year workmanship and 90-day material warranties, and required two to five years of commercial lightning protection experience and A.M. Best-rated insurance. Hillsborough County's sole-source procurement SS2600405 for Earth Networks hardware, software, licensing, and maintenance closed September 11, 2026, at an estimated value of $47,627.54 over two years. The Texas Water Development Board's IFB 58025IFB5519 for temperature sensors, cables, mounting equipment, and pyranometers closed August 25, 2026. Broward County and Fort Lauderdale's RFI BLD2131961F1 regarding the Thor Guard TG-360 lightning detection system closed May 18, 2026. State and local buyers under this code are primarily addressing lightning safety and severe weather monitoring infrastructure needs.
