Background

Solar Power World launched in 2011 under WTWH Media LLC, a digital-first B2B media company founded in 2006 and based in Cleveland, Ohio. The publication quickly established itself as the largest media outlet by reach among U.S. solar contractors, installers, and developers, and became best known for its annual Top Solar Contractors list — the most widely cited ranking of solar companies in the country. Kelly Pickerel joined as editor and became editor-in-chief, leading coverage of technology, business, and policy relevant to the contractor and installer audience. In 2022, WTWH Media secured a strategic partnership with private-equity firm Mountaingate Capital, enabling a series of acquisitions that expanded its portfolio of B2B brands well beyond energy into healthcare, engineering, and foodservice. In July 2026, WTWH Media rebranded the entire parent company as Arrowfly, unifying more than 40 brands under a single corporate identity; Solar Power World continued publishing under that umbrella without a change in editorial direction. As a trade outlet, Solar Power World does not take overt political positions, but its coverage is written from the standpoint of businesses that depend on solar growth — meaning it has reported the Trump administration's second-term tariff escalations (including 145% duties on Chinese panels and the August 2026 polysilicon price floor), tax-credit rollbacks, and permitting delays as concrete business problems for its readers.
