Bests & Worsts Reviews from Amazon

I have Zamp portable panels (200W and 80W) and a Zamp 60amp charge controller on an RV. I recently need to expand and thought I’d try Renogy because they are cheaper. I chose these 100W foldables w/o charge controller because I find my 200W panel is tiresome to move due to its bulk. Comparing Renogy to Zamp I’d say the Reonogy is just as good (functionally) and less expensive. I like that Renogy has the handle attached to the panel; Zamp attaches handle to case. I like the folding locks a bit better than Zamp (both work fine). I think the legs Renogy mechanizm is a better design than Zamp but they’re both work ok. I don’t like that Renogy does not provide a cord as Zamp does. In full sun the Renogy panels meet their performance spec.

Search ‘Download’ did not take me to a download section with registration. Guess I’ll have to mail their cards. The question I have is about service. Zamp’s service is excellent; an knowledgable person answers the phone immediately. I had my 200W panel thrown in the wind and Zamp’s service cost would have been dirt cheap. I decided to get a replacement panel and fix it myself since the damanged panel still worked. Along the way Zamp was completely helpful with repair information. I just NOW called Renogy to see how I would get a replacement panel for a accident. I was on hold maybe 5 minutes and got an agent who kept insisting the damage isn’t covered under warranty. I explained I just want to buy a replacement panel and he explained I couldn’t get it from them and I would not be able to wire the panels. This was all total nonsense. Then I explained I have Zamp and know I can do this and that I am writing this comparison review. THEN he said I could buy a replacement panel and do it myself - just few moments after saying I could not. I don’t know whether this customer service was was in India and the problem was a language barrier or whether he is in the USA. Anyway I’m am not impressed with service given that call. So I decided to continued checking this and I called sales. There is NO replacenment panel that matches this model so this model is NOT replairable. One has to replace the whole unit. Wind damage is a very real possibility for RVers. When I get more panels for the roof of my RV I will likely go back to Zamp and pay extra since I ‘know’ their service is excellent, but for the initial price Renogy is fine. Wind damage is a very real threat to RVers. Given the unit is not repairable (replacement panels) I would not buy another Renogy product. I give this product 1 stars due to the handling of my customer service inquiry and the fact that one cannot repair this panel w/o replacing the whole unit. Early Summer 2019, still under warranty, but alas NO service. The unit blew a diode
