Sungold folding solar panel is one of our main producing line.We have advantages and make improvements as follows:

Bracket:the technology of new bracket has applied to national patent.It use impact molding high quality anodised aluminium,different from others welding bracket,it will not get rust/corrosion even in salty areas.

Controller:we have different controllers,to make difference for customers in their market,also we accept customers’ own controller brand,it will be used after strictly test by our technicals.

Bags:we make thick while light weight bags,to insure the solar panel can be well protected,also,you can put on your logo on the bags.

Sungold hold the spirit”no quality,no future”,we wish to do best quality folding solar panels for you at lowest costs.Your interests and support is our greatest encouragement.
