SDG&E Surpasses 350,000 Rooftop Solar Customers as One in Four Homes Go Solar
San Diego Gas & Electric has reached a major renewable energy milestone, with more than 350,000 residential customers now generating electricity through rooftop solar systems. The utility said this represents more than one in four customers, making it one of the highest residential solar adoption rates in the United States. The company attributes the growth to faster interconnection processes and continued customer investment in clean energy. Increasing rooftop solar penetration is helping modernize California’s electricity grid while supporting greater energy resilience and reduced carbon emissions. SDG&E said the milestone reflects strong collaboration with customers, installers and policymakers as distributed energy resources become an increasingly important component of the state’s transition to a cleaner and more flexible electricity system.
Palladium Energy Secures $66 Million Financing to Expand Utility-Scale Solar Pipeline
Palladium Energy has secured a $66 million development loan from Voya Investment Management to accelerate its utility-scale solar development pipeline across the United States. The financing will support project development activities, including site acquisition, permitting, interconnection, engineering and pre-construction work, strengthening Palladium’s ability to advance multiple projects toward construction. The company said the funding enhances financial flexibility while meeting growing demand for large-scale renewable energy assets from utilities and corporate power buyers. The transaction reflects continued investor confidence in utility-scale solar despite evolving market conditions and reinforces Palladium’s strategy of expanding a diversified portfolio of solar generation projects that support long-term decarbonization and grid reliability.
ES Foundry Expands U.S. Solar Cell Capacity to 3 GW with 2 GW Greenwood Factory Addition
ES Foundry has completed a 2 GW expansion of its solar cell manufacturing facility in Greenwood, South Carolina, increasing its total annual U.S. production capacity to 3 GW as the first solar cell rolled off the new production line. The company said the expansion strengthens domestic solar manufacturing at a time when demand for U.S.-made components continues to grow. The new capacity helps reduce reliance on imported solar cells while supporting developers seeking domestically manufactured products for utility-scale projects. ES Foundry said the operational milestone demonstrates execution rather than future plans and positions the company as one of North America’s largest crystalline silicon solar cell manufacturers, helping close a critical gap in the U.S. solar supply chain.
