For the price, these panels are great. I have actually bought 5 of them to have individual panels for my various batteries. That being said, I am in Florida, and my testing later in the day (still PLENTY of direct sun) had these panels pushing out 135-145W on average. It was enough to charge my batteries up fairly quickly though in some testing, so for the price, I can't complain. I'm betting earlier in the day testing will yield higher output. They are built with an easy to carry method, with a strong handle, and I like the bag thats attached with the adapter in it. For those thinking they come with the wires to go to the solar generator, they do not. Your solar battery might or might not've come with an adapter, but even then, you'd be looking at only a few feet, so plan to buy some wires to put these out in the sun and keep the batteries inside (batteries will operate better that way vs being outside in the heat).
