Do these solar panels have diodes built in for 1 way charging or can they feedback?

You will have to install your own one way diode. This will allow power to go back into the cell and drain a battery.

The cells do not appear to have any external components. They do not have any wires either. The front surface is coated with a thin rigid clear material. The rear surface has solder terminals. I have installed them in an outdoor application about a month ago (july 2014) and they are still functioning as expected. Each of my cells is driving a network of 4 microprocessors. In full sun typically they output about 200 ma @5.1 volts. With sun behind a dense cloud, the output current drops to about 60 ma @ 2.2 volts.

According to the instructions included with the unit, a charge controller is not necessary. "The factory installed diode placed in line with the positive output from the solar panel will prevent reverse current back feeding from battery through the solar panel at night. The use of a blocking diode is typically done when a smaller sized panel is designed for maintaining a float charge to a battery, and a voltage regulator is not used."

no. you will need to use a converter to lessen the wattage on the charge. you will cook your diodes.

As indicated by other reviewers, the solar panel connects to the left two terminals. Battery to the middle two. Be sure to observe proper polarity.

Yes! it has dual charging options, it can be charged via the included solar panel and via any wall outlet.

Yes. Just put em' in and leave them. These chargers go into "Energy Save Mode" when the battery is charged, preventing damage to the cells. They come back on only to "trickle charge" when necessary.

There are packages that include the solar panel. It should list if it is included. I bought one last summer, live in Ohio, and set up a duel gate. The 5 watt panel didn't keep up with our needs. I installed a second panel and it has worked great even through the cold winter. I am very pleased with its performance.

No!!! The output from the Renogy Solar panels is DC (direct current). Your electric panel is AC(alternating current). You need to speak with or consult a qualified electrician.

you can charge via USB or the solar panel sold by Goal Zero which is sold seperately..the charge holds for several hours...we charge once every couple of weeks and use daily for at least an hour or so a day off a USB charge. Much like you would woth a cell phone usb jack.

I have the light part of the unit indoors during the day with the solar panel outside (wire run under door to front deck. I then use the power for light or cell phone charge at night. I have not tried charging the solar panel itself inside, if that is what you are asking.

There is just a solar panel. And you would have to mount it to some post and may need some additional wire to connect it to solar charge controller.

I bought 3 in 2011. I don't recall any instructions. It is designed to charge a 12 volt or lower system. Care must be taken not to over charge the battery. I hooked them up to my car battery for a trickle charge. There is a diode in the black box on the back so at night it will not discharge the battery. Make sure it is hooked up right. check the voltage in sunlight to be sure which is positive and negative. Hook up solar panel positive to battery positive etc.

i don't remember but it's really simple.the solar panels connect to a charge controller witch connects to the battery.then the inverter red cables connect to the positive post and the black to the negative.if you are useing more than one battery parallel the batteries connect the red cables to positive on one battery and the black to negative on the oter battery and the same with the solar panels.

No idea in a solar panel use but they are 12v. So If the panel is 12v you may need to adapt it some how

It will depend on how you plan to connect it to the charge controller and what the total amount of watts of panel you are connecting. So no, but you would need to check.

Yes, Connect the positive lead of the solar charger to the positive terminal of one of the batteries and the negative lead to a negative terminal.
