Ross Williams

President And CEO

Mr. Williams joined Home Energy Systems in 2010 where he began developing and implementing many of the company’s programs and policies that are still in use today. His degree in Business Administration from the University of Pittsburgh as well as his professional experience as a successful project manager for a Washington DC area general contractor served him well when he moved to California and joined the solar industry and its purpose. Mr. Williams spurred initial quick growth of the brand and immediately knew it was his calling. So confident in the business’ direction, in 2015 Mr. Williams purchased the company from its trailblazing founder and has since expanded, improved, and even rebranded the company to HES Solar. Through innovation, a focus on customer care, partnerships with premier solar component providers, and the evolution of a company culture his efforts have resulted in an average annual growth of 30% and recently led to HES Solar’s designation as the 2020 SunPower Commercial Dealer of the Year.

Brad Souza

Vice President of Residential

Mr. Souza joined HES Solar in the Spring of 2020 to oversee the Residential division just as the COVID-19 lockdowns were being enacted. Undaunted, and with 22 years in the energy industry, Mr. Souza led the division through the rapidly changing business landscape and ultimately delivered the division’s best quarter just nine months after taking the reins. Mr. Souza’s work experience at SunPower exposed him to HES Solar’s impressive design, install, and service functions as well as the company culture, and when an opportunity arose for him to grow what he saw as the best solar installer in Southern California he made the leap and has steadily expanded the Residential division. Mr. Souza has earned a Bachelor’s degree in Environmental Resources Engineering with an emphasis on Energy from Humboldt State University and an MBA from the University of Southern California. He is also a licensed Mechanical Engineer in California.

Wenjie Chen

Director Of Commercial

Mr. Chen first applied his Bachelor’s degree in Mechanical Engineering from UC Berkeley to auto industry projects prior to entering the solar industry in 2011 with a stint in design & engineering at Tesla/SolarCity that took him through residential solar and into commercial solar. In July of 2017 Mr. Chen made the jump to HES Solar’s Commercial Division and since the HES Solar Commercial Division has won four straight SunPower Commercial Regional Top Producer of the Year awards as well as being honored with the 2020 SunPower National Commercial Dealer of the Year top designation.

Mr. Salas joined HES Solar in 2010 as an Electrical Apprentice; his customer-first approach and high standards of client satisfaction led him into the role of Construction Manager until the development of the company’s newest division, Service. At that point Mr. Salas was tapped to lead the development of the new division in developing and implementing service agreements that fit customer needs alongside product offerings that accentuate or complement residential solar production and energy efficiency. The department’s formation was partially motivated by Southern California homeowners contacting Hes Solar after they’d been left without a solar partner when their installer left the solar installation field or went out of business completely. Mr. Salas rates carbon emission reduction as a high priority and knows he’s doing important work to keep residential solar systems in California operating at maximum efficiency.

Shortly thereafter Mr. Miller took on commercial design responsibilities and from there transitioned to Assistant Commercial Project Manager, at which point he earned a Project Management Professional Certificate from the University of San Diego. His knowledge, approach, and focus on providing the best quality systems soon advanced Mr. Miller to his current role as Commercial Project Manager where he oversees every step from inception to completion of commercial solar production, storage, and charging projects.
