With a service life of more than 25 years, solar photovoltaic (PV) systems must deliver power consistently and constantly. VSUN’s quality assurance testing validates the production and safety of installed systems during the IQC, IPQC, FQC, and OQC processes. All the processes are strictly under control and we use the latest automation testing equipment. Consistent data collection and reporting allows VSUN experts to gather the information needed to accurately identify the causes of several common problems with solar products and installations. Once we understand the cause and effect of these issues, we can develop an improvement plan. VSUN also offers process improvement suggestions and provide consultation if a problem arises.
