AWESOME
This is a great Solar Panel, does everything as promised and is of the highest quality. Highly recommend.

high quality panels for the money
I installed ten of these panels to supplement my three wind turbines, charging a 5,000 amp-hour battery bank, and they perform as advertised. I've seen the array deliver up to 72 amps @ 14.5 volts with the sun shining directly on them. On a dark, overcast day each panel puts out about 14-20 watts. The price per watt-hour is considerably higher than wind power, but the fact that they make power every day makes them a nice supplement to an existing wind power system.

Works great
I am not an engineer - but I bought this inverter with a Sharp 80W solar panel and a Sunforce charge controller to provide lights in a barn. The power company wanted to charge me 0 to connect power, a month connection fee, and usage It took about a 1/2 day to set things up. Of course the hardest part was installing the solar panel. Once that was done, it was very easy to connect the panel to the charge controller and to the battery. I bought a Sears Marine Battery that is charged by the panel and I run the Cobra inverter off of the battery. I run shop lights and CFC (11W) bulbs for light, radio, and low watt fan. Its great and should pay back in a year. If you have a very low power use application - then this will work.

Incomplete panel..
I have other sunforce 80 watt panels and they all perform wonderfully well. My issue with this panel was half the hardware was missing. Normally the plastic bags holding the parts are sealed, but these were opened. I improvised the mounts and made it work anyway - just something to be careful of in your shipments.

errors
There are quite a few errors in the listing for this solar panel - the dimensions listed are for the shipping size - the actual panel size is 21 X 48 x 2 inches. The listing also says it is suitable for RV and marine use - but the warranty that comes with it states that the warranty is void if used in a mobile or marine enviornment.
The panel itself is very efficient - putting out upwards of 6 amps under good conditions. But my impression is that it is meant only for roof mounting, and is far too fragile to be bouncing around on top of an RV or camper, or mounted on the deck of a boat. The back is protected only by a plastic sheet, and the bottom edge of the aluminum frame is less than 1/8 inch thick - fine for roof mounting only.
The mounting hardware that came with my sample bears no relation the that pictured in the instructions (however the picture in the listing is accurate); and there were no battery clamps or quick connects.
