Sure. Personal decision. From everything I read and discussed with folks the hard panels are more efficient than any of the flexible, or semi flexible panels. More importantly to me was life expectancy where the hard panel also wins. Based on that and the need for me to be able to move this between a few different platforms, I decided on a suitcase model. That narrowed the field to Renogy, Overland Solar and Zamp. I eliminated Zamp because it did not bring anything to the table (in my understanding) that the Renogy and OS didn't. Renogy got a lot of recommendations due to price per watt and people's experience. They are releasing a new model that is smaller and lighter which I like. They do not have an official release date yet, so if you order from them, or off Amazon, you do not know when you will get the product. OS also has great revies and tales from personal experience. OS compares at 25% more expensive (don't bore me with saying more than that due to the 90 vs 100 watt comparison, either will get the job done for me.) For a purchase this size, I called each company. This was my deciding factor.
The Renogy rep that answered the phone seemed to be a general customer service rep, he may as well have been working the front desk at one of the centers I run. He could not tell me much about the new model, other than it was smaller and lighter (I already knew). I asked if the controller was going to be waterproof, he did not know. I asked if 100watts was the right size for my application. He either was not sure or was not interested. He could not tell me a ship date, other than, "They say January 2017". So this is where it gets personal... those of you who supervise understand that it drives me crazy when employees say "they" instead of "we". Points out a cultural issue at the company in my crusty old man jaded opinion
... (sorry
@TangoBlue I know that is usually your gig
)
So immediately following that conversation called Overland Solar. Brian picked up the phone on the second ring. He asked ME the questions to make sure I was sizing it right, what connectors I wanted, when I needed it by and how I had heard of them. When he found out I was at Expo east he was interested and wanted to know what I thought, etc... and if I was going to other events in 2017. In short, I was dealing with an expert, which is what I need in regard to this project... That is worth it to spend the extra $ for me, perhaps a consulting fee concept.
Still... this is a lot of money, so I deferred ordering right away. Now that the order has been placed, I received receipt right away and a tracking number a few hours later when the west coast woke up. Further, Brian followed up by email thanking me for the order, recognized me from our conversation last week and noted that they are about to get slammed by a winter storm, so keep an eye on the tracking, as it might take a bit longer to arrive.
I am happy so far. We'll see how things work out. Hope that helps.
