Leeward is adding solar panels to its portfolio of 21 wind farms across nine states that generate about 2,000 megawatts of capacity.
“As one of the few solar companies that both entered and exited this last decade, and the only U.S.-headquartered company among the 10 largest [photovoltaic] module manufacturers globally, we have continued to adapt our business model to remain competitive and differentiated in a constantly evolving market," Widmar said.
