What if your panel is in a secluded area where there is very little sun? Will the panel keep my battery charged?

Mine fully recharges in full shade on a feeder that has been out for about 3 years. No problems with this unit.....I have bought more.

Mine panel reads out around 8 volts on my multimeter in the garage without direct sun. It should work fine for you. Mine has been absolutely problem free for about a year and a half now.

I don't know. I would probably go with a larger solar charger to gather more light?

Yes you will need a controller a panel this big would quickly destroy the battery. When it is dark your battery will not discharge any faster than it would naturally.

Of course friend, the panel is high efficiency, full sun generates 22 volts, you need a charge controller 12 Volt so you do not overload the system, it will keep you charged and when the battery is charged, disconnect, which prevents damage to your batteries!

The solar panel comes with a stake to put it in the ground or you can also attack it to the wall. It can be pivoted around. The lamp works very well&lt; at least 9-10 hrs. of light. and it lights up to 6 meters depending of how you place it. I live in Curacao, where we have a lot of sun, so no problems to charge the panel.

I've found that a 100-120 watt solar panel will be able to recharge this system from empty to 80-90% full in a good sunny day's worth of sun. It takes the full day to do it and if it's cloudy or worse then expect 2-3 days depending on conditions. You will need to add a solar charge controller to help with the task and to protect the battery from being over charged.

You'll be charging from the battery pack not the panel it self. It goes sun panel battery then device. So it will be a continuous charge until those barriers are depleted. And they just recharge from the panels

It seems like it charges some. Mine died on me after hours of being on. Didn't think about turning off. Latter next day I noticed it was on. One note though The solar panel is small and not of the latest technology. I doubt you would get as good of charge if left on. Hope this helps some.

Mine works great but if you don't use it it will lose some power you can charge it 2 ways when you are not using it leave it in the sun light

I don't think this Battery Tender solar panel is made for outdoor use. It should placed inside the trailer, behind a south facing window, to receive maximum sun exposure.

I can only tell you what I did. I have a 400W inverter and a 12V car battery. I use this in my small horse barn that I wired for three bulbs and an outlet. There are 3 small watt bulbs. The panel keeps the battery at full charge with no problem. I don't use the electric all the time, and for only short periods when I do, so I don't know how long the charge will last.

As long as you wipe off the solar glass panel and let the sunshine charge it up however there are small round batteries

No, it requires the sun to charge and does not store charge. It won't contribute to draining your battery so you can keep it plugged in.

Be sure you put a 'charge controller' (regulator) between the panel and the battery. If you don't, you will overcharge the battery daytime, and fry the panel at night (because the battery will back up into the panel and fry it).

I keep my light in a window to keep it charged, I've never charged with USB, so sorry, I'm not sure. I would assume it would. Mine seems to show the red light only when the solar screen is exposed to light (any kind), showing it's charging.

It will maintain a battery with a reasonable amount of direct sunlight on the panel

This system is not designed to 'charge up' and then run off of a battery, instead it is direct powered from the solar panels to the motor. This means that it will run while under sunlight or lamp light and will stop when not in the light.

It does not shut off automatically, and I'm not sure why you would want it to. I guess you could cover the panel from the sun if you wanted to, or disconnect the battery terminals.
