Rated 5 out of 5 by piddln !8 watt solar panel/ 7 amp charge controller
I installed this unit on the roof of my RV storage building to maintain the house batteries. I did a bench test in the back yard using 2 Trojan 125 batteries and after 10 days was satisfied that battery voltage was being maintained. I then installed the panel on the roof of my metal building with the panel axis East and West so as to take advantage of the full arc of the Sun. Install was simple drilled pilot holes for the 4 fasteners and an entry hole for the 12' power cord. Ran the wire down the truss using plastic ties every 2'. Attached power cord to the charge controller and to the battery using eyelets. (I found it necessarry to cut the wires to battery terminals and install connectors. This is so when I leave the building I just disconnect the connectors and leave the charge controller and power cord attached to the building)
The set up is maintaining the charge on my 4 6 volt AGM house batteries at 13V or better. Batteries were charged to 13 V when I stored the motor home. Prior to using the solar panel house batteries would slowly deplete about .3 volts every 7-10 days. Now this is not a problem and I'm confident that I will not damage batteries by allowing them to discharge below 50%.
Tech support from Fernando and Simon has been excellent on the questions I posed before and after purchase.
Rated 5 out of 5 by Imnew2hu Works as advertised
i bought 3 of these over all good value for the money I just wish someone would sell a 75 to 100 watt panel for the amount I had in three of these plus s/h.

Rated 5 out of 5 Great (smaller) solar panel
I bought this to recharge a 12V battery I'm using in my car to power an Endless Breeze 12V fan (also an excellent buy). I checked the dimensions of this solar panel prior to purchase to make sure it had room to sit on the dashboard of my Corolla, which it does. I've only used it a few times, but it has apparently fully recharged my battery each time. (Make sure to use the included voltage regulator to avoid potentially over-charging your battery.) I'm enjoying using my first "entry" into the world of green energy!

Ordered this item and only recieved the panel, no hardware. Make sure to check carefully when you take receipt of the package.
