it is) so instant that it deducted a star. It only has a small junction box that only fits a fairly small two-wire cable. If you want to run a thicker PV cable to this junction box, you can't. I decided to solder a two core 16 AWG cable with a 2.1mm connector on the other end. This is probably the thickest cable you can plug into this small junction box. *** So, just to be clear, all the pictures I've posted with the cable on this solar panel show the cable I installed on it. * ** I connected it to the charging port of the power supply/inverter and in the currently low October sun the maximum recorded was just over 25 watts. It's not bad at all to be honest and I'm sure it will be higher in the summer months. This monocrystalline solar panel appears to be well constructed and again it's just a simple panel with no poles or cables. BTW, I found a very easy way to make a prop, just using corrugated plastic sign stock. This picture is included. I also added rubber feet to the back of the frame so that when I charge my RV's chassis battery I can easily mount them on the hood when facing south. Despite the error in the seller's description, I think this is a great monocrystalline solar panel and at the current price (just under $40) I think it's worth it. However, if you are new to a soldering iron and are looking for a corded or corded and controller soldering iron, you may want to take a look at the other kits available. 4 stars.
