Could be a minor detail for others but my second panel came with no grommets. We are full timers on the road for the past 10 years (camper) and I like to put my panels on the hood of the truck (slide in camper) or staked in the ground each with a 30' extension. I now have to glue 4 rings in the back of this 'no grommets' panel and hopefully it will work with the stakes versus grommets and thin line so the wind doesn't take it. Please insert in your description "no grommets". Besides that it is a great panel while weighing only 4lbs easy to handle and store on the back seat of the truck. My first panel also came with 2 thin foam sheets which are nice to use when stored. Stay well. Ara

I wouldn't recommend buying this kit because your not going to get the controller that is listed in the picture, I bought this kit and the controller i got looks nothing like the one shown in the add. The one i got doesn't have any USB charging ports and no LCD screen telling your battery voltage. So if you want that on your controller like i did, i recommend buying them separately, its also cheaper. But the panel seems to be working so i don't want to return it, i am just stuck with this charge controller i guess. The panel works so far. Thanks

Okay. .... Being a Electric Vehicle designer, I put this through the test. If you purchase a 120W panel expect about 66 watts of real power back to your battery while in charging mode. Once connected to a 12V battery I recieved 13.2 volts on FULL sun. My controller shows amps and I was getting about 4.8 amps from each panel. Math: 13.2 volts X 4.8 amps is equal to exactly 63.36 watts in FULL California sun. For a 200 amp lithium 12v battery expect around 6 hours of full sun light and that would equal 7 days to charge one battery using one of these panels. It would take a (12v and a 400Amp) lithium battery set up to give you 4 hours of AC for a 300 sq ft room on a hot day. *If you use a marine lead battery expect half the power. Lithium batteries seem to give about double the output. This means your 120watt panel will actually yield 63.36 watts while charging a battery. I checked other sites and panels and it looks like they are all the same as this panel. I will order more panels and test against this type of panel.Read full review

The guy that is mentioning the MPPT controler issue is fully WRONG, the solar panel works perfectly well give an estimate of 110 WATTS. No MPPT controler used on the test. This solar panel can be mix with any combination of panels if you know your way around.
