Silfab Solar has set out a plan to begin operating its solar cell production facility in Fort Mill, South Carolina, according to Solar Power World. The company has faced safety concerns voiced by the community located along the North Carolina border regarding the plant’s operation.
Silfab chose on its own to bring in TRC Engineers to carry out an independent engineering assessment of the methods and procedures used to prevent and respond to leaks in its solar cell manufacturing processes. The manufacturing process relies on specific chemicals, including silane, anhydrous ammonia, hydrochloric acid, potassium hydroxide and hydrofluoric acid, to convert a silicon wafer into a solar cell. A contained chemical incident earlier this year raised questions about the safety of the Silfab site.
TRC issued a detailed report determining that Silfab had designed and installed equipment featuring multiple redundant safety features that satisfied or surpassed regulatory requirements. That report has been provided to the South Carolina Dept. of Environmental Services.
TRC also offered suggestions for further strengthening safety at the site, such as installing additional detection systems, alarms and shut-off valves across the plant. Silfab has either already carried out those suggestions or will do so as manufacturing lines begin operation. The company anticipates that commissioning of the lines will start on Oct. 19.
Paolo Maccario, Silfab president and CEO, said that following the comprehensive, thorough and independent review by TRC Engineers, the company is proud that its existing safety systems and operational controls were confirmed to meet or exceed regulatory standards. He added that Silfab went further by acting decisively to implement additional recommendations, strengthening system redundancies, enhancing real-time monitoring and advancing emergency response coordination.
Silfab has posted the report findings and commissioning plans for the public on its website.
