Carrie Ryan received a letter thanking her for her contributions to the success of Sandia National Laboratories' Photovoltaic Regional Test Centers (RTCs) project. The RTCs, located in five states, conduct long-term experiments on solar panel performance and reliability, providing valuable data and insights to US solar companies. Carrie's administrative support and customer service have helped make the RTCs project a success despite changing conditions in the industry and evolving business plans over the past year. Sandia's RTCs are strategically important as they brief high-level government officials on energy issues.
