BownessonWindermere

BownessonWindermere is a private enterprise headquartered in Wilmington, North Carolina, specializing in renewable energy solutions and technology consulting. The company was founded in 2012 by engineers Alex Bownesson and Maria Windermere, both of whom previously worked at leading environmental research institutions. Since its inception, BownessonWindermere has expanded its operations to include offices in Austin, Texas, and Seattle, Washington, allowing it to serve clients across the United States and select international markets.

The firm’s primary product line consists of modular solar panel arrays, advanced battery storage systems, and analytics platforms that monitor energy consumption and generation in real time. Its flagship product, the Vantage System, integrates photovoltaic panels with smart inverters and predictive maintenance software. In addition to hardware offerings, BownessonWindermere provides consulting services in energy efficiency, green building design, and compliance with federal and state environmental regulations.

BownessonWindermere has participated in several government-sponsored research initiatives, including partnerships with the Department of Energy and the National Renewable Energy Laboratory. In 2018 it received a grant to develop a low-cost, high-efficiency thin-film solar cell, which was later incorporated into its commercial product lineup. The company is also active in community outreach, sponsoring local STEM programs and organizing workshops to educate the public about sustainable energy practices.

As of 2025, BownessonWindermere employs approximately 350 staff members and reports annual revenues of around $85 million. The company remains privately held, with ownership concentrated among the founding partners and a group of institutional investors focused on long-term growth in the renewable energy sector.
