WindEnergy7

What WindEnergy7 does

WindEnergy7 LLC is an Ohio-based, privately held manufacturer founded in 2008 by inventor Samuel Hargis. The company designs and sells hybrid wind and solar home energy kits for the residential and small commercial market, with its flagship RoofMill system being a roof-mounted wind turbine using a patented mount design certified to withstand 130 mph winds. The product portfolio spans roof-mounted turbines (RoofMill, HO-2.8kW and HO-4.2kW kits), tower-mounted turbines (TowerMill on a 36-45 foot monopole delivering 4.0kW per unit), modular multi-turbine arrays (Home Wind Farm up to 6-10kW), and solar-only electric kits, all designed around a 4-way emergency power architecture that integrates wind, solar, battery bank, and grid sources. All systems are Grid-Tie certified to UL 1741 and carry direct-drive generators with lifetime bearings and an ElectroBrake speed limitation system for high-wind operation.

The company's business model is hardware sales through two channels: direct-to-consumer e-commerce on windenergy7.com with UPS shipping, and a customer-to-dealer network where purchasers can become local dealers or installers for their county territory at no additional investment. Hardware is sold as complete turnkey kits priced from approximately $5,990 to $16,990, with all systems eligible for the 30% IRS residential renewable energy tax credit. The company provides financing with no-money-down options and government-backed fixed-rate loan programs processed in 11 days. Customer segments are primarily residential homeowners seeking to reduce electricity costs or achieve energy independence, with secondary segments in farm/ranch and small business applications. Systems have been installed across approximately 40 US states and exported to Canada, Mexico, Asia, Africa, and Europe.

WindEnergy7 operates as a lean, founder-financed, owner-operated enterprise with no external capital, no debt, and self-described low overhead. The company holds patents on its rooftop mount and home wind turbine kits, won a 2010 Earth Day Green Design Contest Award for the RoofMill, and maintains an active WindPower Forums community alongside content marketing via blog, YouTube, Twitter, and Google+. No revenue, headcount, or funding figures are publicly disclosed.

Emerging players

• EcoFlow: Provider of portable power stations, residential battery, and solar+storage bundles targeting homeowners seeking backup power. Comparable resilience-driven value proposition and home energy buyer, though solar+battery rather than wind.
• UGE International (formerly Urban Green Energy): Distributed wind and solar-energy company focused on building-integrated and small commercial installations. Comparable distributed-wind focus, though historically larger commercial than residential.
• Northern Power Systems: Manufacturer of small to medium wind turbines and permanent-magnet generators used in distributed and microgrid applications. Comparable small-wind technology stack and direct-drive architecture.

Direct peers

• Xzeres Wind: Designer and manufacturer of small wind turbines for residential, agricultural, and small commercial use. Comparable small-wind product line, dealer distribution approach, and target segments (farm/ranch, home).
• Missouri Wind and Solar: US small-business seller of wind and solar hybrid kits for residential, farm, and off-grid use. Comparable hybrid wind/solar product mix, target customer, and online/direct-to-consumer GTM.
• Nature Power: Retail-oriented brand selling small wind turbines and solar panels for residential, RV, and off-grid use. Comparable residential/small-business renewable energy kit portfolio.
• Primus Wind Power (formerly Southwest Windpower): Manufacturer of small wind turbines (Skystream, Air) for residential and remote applications. Comparable product category (sub-10kW small wind), target customer (homeowner/off-grid), and hybrid-ready architecture.
• Bergey Windpower: US manufacturer of small and residential-scale wind turbines (e.g., Excel and BWC series). Most direct comparator to WindEnergy7 in the home/light-commercial small-wind category, with a comparable dealer-driven sales model.
• Aeolos Wind Turbine: Manufacturer of small horizontal-axis wind turbines for residential, commercial, and hybrid applications. Comparable product category (sub-10kW small wind) and customer base.

Broad incumbents

• Generac: Incumbent in home backup power with a deep installer network and PWRcell residential solar+storage line. Competes for the same homeowner-resilience wallet share and serves as a scale benchmark for residential backup-power GTM.
