    Work great kept my travel trailer battery charged
  

*by T***M on Reviewed in the United States on July 29, 2019*

Worked well of screen control module did not allow flush mount

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    If you must absolutely have a flexible solar array, beware of the compromises
  

*by A***N on Reviewed in the United States on March 25, 2019*

It's just not as robust as you would like for charging a battery through an icy winter.  A good concept, but nothing beats a glass covered monocrystalline panel.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Here it is to the best of my knowledge
  

*by B***Z on Reviewed in the United States on December 28, 2017*

What the problem with Solar Panel's is that the people reviewing lack certain knowledge for the subject matter at hand.  Here it is to the best of my knowledge. I am an educated man. I bought one solar panel, and this one is my second. They work all right. Will charge up a battery you have tanked down 12.4v or 12.1v. These take time to charge, however if you have patience they will do the job very well.  I will be using this one to keep my vehicle battery charged up to the maximum, (13.24v.)  Types of silicon cells.  There are two types currently in production at this time. Monocrystalline, and Polycrystalline.  As the name states the Monocrystalline means one cell, and of course Polycrystalline means more than one. The Monocrystalline has approximately a conversion efficiency of 22.5%While the Polycrystalline has about 14-16%  Due to manufacturing constraints most of your silicone cells are Polycrystalline. They are just as good, however may take a little longer to charge.  You may try these Solar Panels, and if you don't like them, you may return them to Amazon where you always get a fair shake at the product.
