What Skycool Systems does

SkyCool Systems, Inc. is a private Mountain View, California-based company (founded 2016, technology originating from Stanford research dating to 2012) that commercializes Passive Daytime Radiative Cooling (PDRC) — a physics-based mechanism that rejects heat from a surface to outer space by combining ultra-high solar reflectivity with selective infrared emission in the 8–13 micron atmospheric transparency window. The company holds 5+ patents on PDRC, with the foundational research published in Nature as one of the most-cited papers in physics. Its product portfolio centers on the proprietary SkyCool dual-mode optical film, delivered in two primary platforms: the SkyCool Panel, an aluminum panel with fluid channels used as a renewable condenser for refrigeration and data center heat rejection (compatible with HFC, CO2, and water/glycol systems), and the SkyCool Roof, a film-based roofing solution available as SkyCool Overlay for retrofits and UltraCool Roof for new construction in partnership with major roof manufacturers.

SkyCool sells hardware via project-based, multi-year enterprise contracts to data center operators, grocery and cold-chain retailers (notably Target, where panels have been tested across six U.S. states including a CO2 site in Texas), warehouse operators, and commercial real estate owners. Distribution combines direct enterprise field sales with channel partnerships through roofing contractors and industrial installation partners; technical validation is supported by NREL via the Wells Fargo IN2 incubator program. The company is led by CEO Arjun Saroya (appointed August 2023), with co-founders Eli Goldstein (Ph.D.) as CTO and Aaswath Raman (Ph.D.) as Chief Scientist, alongside a leadership team that includes a CCO, VP of Engineering, and Senior Directors of Operations and Projects. As of late 2025, SkyCool had raised roughly $9.5M across equity and nondilutive sources, been selected as a finalist for the 2026 BloombergNEF Pioneers Challenge in sustainable data center infrastructure, and accumulated 30+ installation sites.

Revenue model

1. SkyCool Panel Sales: Sale of radiative cooling panels for heat rejection applications in data centers, refrigeration systems, and industrial facilities. Panels replace or augment traditional condensers and dry coolers. Revenue from direct equipment sales plus installation and integration services.
2. SkyCool Roof Sales: Sale of rooftop radiative cooling film/products. Two product lines: SkyCool Overlay (retrofit) and UltraCool Roof (new roof with pre-applied film). Includes professional installation through roofing contractor partners.
3. Professional Services: Technical consulting, system design, and integration services for deploying SkyCool products in customer facilities. Includes validation support and performance monitoring.

Core offering

SkyCool Systems designs, manufactures, and sells passive radiative cooling hardware—primarily the SkyCool Panel (a rooftop renewable condenser for heat rejection) and the SkyCool Roof product family (a cool-roofing film solution available as Overlay retrofit and UltraCool Roof pre-applied substrates)—all built on its proprietary dual-mode optical SkyCool Film that radiates heat to outer space to cool below ambient air temperature without electricity, refrigerants, or water. The company sells directly to enterprise customers in data centers, grocery/cold-chain refrigeration, and commercial warehouses/real estate.

Product overview

SkyCool Systems offers a portfolio of passive radiative cooling products based on Passive Daytime Radiative Cooling (PDRC) technology invented at Stanford. The product line consists of SkyCool Panel (a renewable condenser for refrigeration and data center cooling) and SkyCool Roof (a category-defining cool roof available as Overlay or UltraCool variants), both powered by the proprietary SkyCool Film technology. SkyCool Film is a dual-mode optical film that reflects sunlight and emits infrared radiation to the cold sink of outer space, enabling cooling below ambient temperatures with no energy input, no water evaporation, and no moving parts. The products serve commercial building cooling, data center heat rejection, cold chain/grocery refrigeration, and warehouse space cooling applications.

Functional benefit

Products and services

• SkyCool Panel A rooftop cooling panel that acts as a renewable condenser, replacing traditional air-cooled condensers. The panel uses dual-mode optical film on an aluminum surface with fluid channels to passively reject heat to space. Compatible with HFC, CO2, and water/glycol systems, scalable from small refrigeration upgrades to gigawatt-scale data center deployments. Designed for data center operators and refrigeration/cold-chain facilities needing high-capacity passive heat rejection.
• SkyCool Roof A film-based roofing solution that keeps buildings cooler than ambient air 24 hours a day without electricity. Available in two variants: SkyCool Overlay (retrofit for existing roofs) and UltraCool Roof (pre-applied to new TPO, modbit, or metal substrates). Reduces interior temperatures by an average of 7°F compared to basic roofs. Targets commercial real estate owners and warehouse operators.
• SkyCool Overlay Retrofit variant of SkyCool Roof designed to extend the life of existing roofs (TPO, modbit, concrete, and metal). Applied as a film over existing roofing substrate without requiring roof replacement or insulation installation. Targets existing commercial buildings and warehouses.
• UltraCool Roof Brand-new roofing substrate (TPO, modbit, or metal) with SkyCool film pre-applied during manufacturing. Developed in partnership with and warranted by major roof manufacturers. Designed for new construction and re-roofing projects where SkyCool film is integrated at the manufacturing stage.
