Instapark® NEW All Black 20W Mono-crystalline Solar Panel with 12V Solar Charge Controller

Verry good solar panel that include a USB outlet on the solar controler ( Not for I-phone or others electronics ). Work well on sunny or not sunny day. Nice to have a twelve feet wire, it will eliminate the outside connection. Very responsable supplier I had a problem with power of delivered pannel and they correct it promptly.

They may claim it to be a '20 watt' panel, but if you are to hook this up to a 12 volt battery, you will only get 15 watts, just so you realize it. Charging voltage is 13-14 volts times max amps of 1.17 equals 15.2-16.4 watts, minus ??? watts from power needed for the charger.

I have not actually done all of the tests necessary to determine if

the panel I received is putting out 20W in in full sunlight, but it does seem to be working. It does look different slightly from what is pictured with

I would not trust the attached charger though. I have a feeling that it is "trickle draining" the battery at night. Also, it has a USB port built into the side which has a warning on it not to use with sensitive electronic devices like the iPod and iPhone. I would just tape it up just to avoid blowing out your precious USB powered electronics.

Of course, I have this hooked up to a 12V battery and a quality inverter. This panel is fine for maintaining one or two 12V batteries at full charge. It is not powerful enough of course for any type of continuous power draining applications.

I bought it primarily as a battery charger.

I bought a smaller 5 watt panel & was very happy. The charge controller was pre wired & looked just like the picture. When I got this panel I was shocked. It is not pre wiredcharge controller differentneeds wiringwires pulling directly on panel connectionno where near what is shown in the picture! I would send it back but the charge controller is not important to me on my application and I can fix where the wires enter the panel junction box. Bewareok if you don't mind fixing the shoddy wiringcrappy charge controller.

Seems to do a fine job keeping my RV battery topped off. The controller is nothing more than a plastic box with two dummy lights. There is no USB port in the current version.

Mounting options are limited and I had to build my own brackets to mount on a RV roof.

5 stars on functionality w/ -1 star for mounting limitations and cheap controller.
