Thin film panels degrade quicker than normal though so unfortunately it does not have a 2025 year output warranty so if you plan on making this a long term investment do it at your own risk

It was a waste of money

I purchased this panel direct from lensun usa

I felt foolish when i found that the cables coming from the panel and the extension cables to the controller were keyed a set of male and female for each that were reversed for positive and negative so that you cant crossconnect them once youve wired the controller and batteries correctly

A good 14 visible tin on both wires at the junction box on one panel and the same visible but on only one wire on the other panel

The warranteei wrote lensun sent them pictures of the offending cables and junction boxes explained how i used the panels and asked if this was covered under the 2 year warrantee for materials and workmanship

Ive hear many rave about how great their warrantee is but their issues were in the solar cells themselves
