Inept customer service and poor quality control
Inept customer service. Closes warranty claim cases before a response can be made. I made a warranty claim on a two year old solar panel that produces no power. As requested, I supplied detailed photographs and written description of the problem. Response was sent at 4 AM requesting further photographs. Claim was closed 48 hours later without my response. After complaining, Renogy customer support opened a new case without my request and then closed it again without my response. Clearly they are not concerned with my input nor are they interested in honoring the warranty. If this tells you what Renogy cares about... they contacted me after I posted complaints to BBB and Trustpilot. They addressed me by the wrong name. After another message, they finally told me that the warranty period had passed. I then repaired the panel myself and found and unsoldered joint on the negative bus bar. THERE WAS NO SOLDER. It was held together by the glass and the plastic backing. Poor quality control. The unsoldered joint got hot enough to melt the plastic on the back of the panel. Scary.
