    Got this today. Seems to be made well, no issues with shipping. I got it at around 4:30pm Michigan time, put it on the kitchen table and hooked up a volt meter to the clips and the meter showed the putting our around 4volts, took it next to a window, went up to around 14, went outside and got around 22. May not put out the 24 that it’s rated for, but this leads me to believe that I will have no problems getting that when it’s sunny out.

    Wire quality seems pretty good. If there are any issues going forward or if I learn anything new about this, I will try to update this review.

    I have three of these to keep 12V batteries charged on various low use machines (boat, generator, lawn tractor,plow car). I wired a diode in series to protect the panel from the battery at night (not sure this is necessary). These things survive rain, snow, and all the insults of NH winters. Puts out about half an amp in full sun.

    This has worked quite well so far. Charges the battery quickly and seems well made. Fraction of the price of others. However I wish the cord were longer and had a cigarette lighter plug.

    It provides instant power as soon as sunlight touches it. I am currently using it in a south facing window because I am too lazy to install it outside. It gets hot enough so I am pretty sure it will be fine in our mild Canadian winters. The battery clips and blocking diode are a nice touch.

    Worked well for 4 years and then died. The fan motor I had it plugged into outlasted it.

    I connected this 7W panel to a size 27 deep cycle using a cheap shumacher charge controller. At first it didn’t show a charge so I had to put the panel outside in the sun to get it to show charging. The controller was between 8 and 9V DC when placed in a window and jumped to 13.5V DC when the panel was moved outside facing the sun.
    The 12.6×15.7 panel is glass inside a good aluminum frame and has 2 rods for angle braces and 4 plates for flat mounting. The battery clamp is low end and has a direct 6′ wire to the panel. At first I thought the glass was broken in the box but it was the metal parts rattling against it. I gave it 4 stars because of the poor packaging and the fact that it didn’t charge from inside a window in low light.

    Produces good power even in overcast conditions. Did the tongue test to see that it was working, I got a charge as well as the battery.

  8. K. R. –

    Giving this 3 Stars.. for now – might go higher or lower later. Lost one star for not being the same as the photo on the product page. This panel has a metal frame, not plastic. And there isn’t a modular style cable. Actually this panel may be more heavy duty built than the plastic one.

    Lost another Star because it was an obvious returned unit. Package had been opened and all the parts that should have been bagged were loose. The bags were all ripped open.

    Still for the price I’m not going to complain – if it works. Haven’t had a chance yet to test it out. Will be doing that soon. Will add to this review whem I do.

    Tested this in full Texas sunshine with a volt meter.. No load.. Was getting 23.5 Volts.. Haven’t checked the current yet.

    Product arrived earlier than expected. A pleasant surprise . I will use this solar panel in the next week when I go fishing
    In the far north to keep my fish finder battery charged. I’m sure it will work just fine. Was as advertised and packaged well.

    I use this to power a security (Trail) camera that takes many pictures a day. Its bigger than necessary but being amorphous, the camera never looses power even after several cloudy days in winter. I expect it will still be enough power as it looses efficiency in a few years. I use the screw holes in the back for mounting on plywood and its solid as a rock. I bought another for a spare.

  11. CC –

    Best price for replacement-easy to install.

  12. Lyle A –

    Works just like my other one keeps rv battery charged fine

  13. Amazon Customer –
