Bests & Worsts Reviews from Amazon

I initially gave this panel a five star review as it performed well upon installation. Now that its been on my RV roof for less than 4 months I have to revise that rating. The panel has stopped working. No output at all. The surface of the panel has delaminated from the substrate and watered has infiltrated & shorted out the underlying electronics or cells. This occurred on top of an RV where no one ever walks. How they could claim it can be glued to a boat & walked upon is beyond me. I tried in vain to contact Renogy without any success. I called Amazon & they arranged for me to receive a replacement panel without charge. Thank you Amazon. It is still left up to me to find a way to safely remove the glued down defective panel without ripping my rubber roof. I will install the replacement Renogy panel simply because I have no other option. I can't afford another type panel. I will never purchase anything else from Renogy simply because there is no customer service after the sale & the quality of their products is questionable.
