What Bergey Windpower Co., LLC does

Bergey Windpower Co., LLC is a Norman, Oklahoma-based designer, manufacturer, and seller of small horizontal-axis wind turbines (primarily the Excel 10 at 10 kW and the Excel 15 at 15 kW) targeted at distributed generation applications — residential homes, farms and ranches, small commercial businesses, remote telecom sites, and village/microgrid electrification in developing markets. Core technology centers on a proprietary downwind rotor architecture with a permanent-magnet alternator, paired with grid-tie and battery-based power electronics platforms (PowerSync II, PowerSync 25, VCS II) and supporting tower infrastructure (guyed-lattice, self-supporting, tilt-up lattice). The Excel 15 flagship features only two moving parts, a 31-foot rotor diameter, and carbon fiber blades; the Excel 10 has a documented field life exceeding 26 years with 100% availability per customer evidence and carries what the company describes as the industry's longest warranty.

The company generates revenue primarily through one-time hardware sales (turbines, towers, inverters) priced approximately $40,000–$95,000 for residential grid-tied installations, $2,000–$100,000 for telecom off-grid systems, and $20,000–$150,000 for village power systems. Distribution runs through two parallel channels: a worldwide Certified Dealer network of 500+ resellers providing turnkey installation and on-site warranty service, and direct-from-factory sales supported by installation manuals and ground-erection procedures. An installed cost is materially reduced for U.S. buyers by the 30% federal residential Investment Tax Credit under the Inflation Reduction Act, plus state incentives and business depreciation benefits — making policy and tax-credit continuity a critical demand driver. Mike Bergey has served as President & CEO since 1987; the company's history is closely tied to his and his late co-founder Karl Bergey's authoring of foundational small-wind industry standards (AWEA Performance Rating Standard → IEC 61400-12, the 2008 AWEA Small Wind certification standard, IEC 61400-2, UL 6142).

The company is privately held under founder-family control (LLC), has 11–50 employees per firmographic data, and receives modest non-dilutive federal funding (notably a $178,984 U.S. DOE grant in May 2023). Revenue is not publicly disclosed. Beyond the core small-wind business, the company operates a side program — DARPS (Deployable Advanced Renewable Power System), a 46 kWp wind/solar hybrid system oriented toward military/deployable applications — indicating selective diversification into adjacent verticals without abandoning the residential and small-commercial core.

Product overview

Bergey Windpower Co. is a Norman, Oklahoma-based manufacturer of small wind turbines and supporting power electronics, offering a platform-plus-modules product architecture rather than a single unified product. The company's core offering centers on the Excel family of small wind turbines — currently the Excel 15 (flagship 15 kW grid-tied turbine with carbon fiber blades and two moving parts) and the Excel 10 (10 kW turbine offered in both grid-tied and off-grid versions) — which together account for the bulk of its sales. Around this core, Bergey offers supporting infrastructure products (Tower Options including guyed-lattice, self-supporting, and tilt-up lattice tower configurations) and power electronics modules (PowerSync 25 grid-tie inverter, PowerSync II battery-less system, VCS II battery-backup system). Legacy products (Excel 1, Excel 6, Excel 7.5 R) remain supported via documentation downloads. Beyond commercial residential, farm, small-business, and remote telecom products, Bergey operates a side program — the Deployable Advanced Renewable Power System (DARPS), a 46 kWp wind system. Across the portfolio, all Bergey turbines are designed for distributed, small-scale deployment, are distributed through a worldwide network of over 500 Certified Dealers plus direct factory sales, and meet the AWEA 2008 Small Wind Turbine Certification Standard and UL 6142 / IEC 61400-2 electrical and safety standards.
