I like the 200watt panel so far. It looks to be well made and worth the money. It has a good conversion rate so far. Giving me as high as 180 watts in full sun by itself. In series with a EBL panel which is also rated at 200 watts I have seen as high as 399 watts. For portable panel it is doing very well for me. It came with a very useful set of universal connections It’s light and easy to setup . Would buy it again if the price is what I paid for it. Very good packing job as it arrived tripple boxed.
