Is there backup to the solar power, so if I need to use it in the dark it will work?

The power comes from AAA rechatgable batteries, the solar panel recharges those batteries, so you can use it with daylight or in the dark.

It stores quite a bit of energy on a full charge, so you should be fine as long as you're not in the dark for days at a time.

The solar energy must be stored in some sort of capacitor, but you can't really see a "battery"

It is solar powered and needs good sun light to charge the battery; however, it is not very bright. I added a piece of mirror to the inside bottom and the led light reflecting on the mirror makes it appear a little brighter. There is a button to push to turn it on and once it is fully charged, it will come on automatically when it gets dark.

If in a remote area with no power available, then a solar panel and 12v battery can be used for power. Available here from Amazon.

Yes. The "load" outputs on this controller can be programmed to come on at different times of the day for different lenghts of time. As for not putting out power when there is not enough sun, it does that automatically by monitoring the incoming voltage from both the battery and the solar panel. If it is too low the "load" outputs will disconnect automatically and only reconnect automatically when there is sufficient voltage coming in again.

Yes there is a battery backup!!! You might have to put the battery's in it.

You can just hook it up +&-. Or you can get a charge controller that will desulfinate the battery, not overcharge and not discharge at night. There is lots of 'em available... Me, I like the Battery Tender 021-1162 Solar Panel Charger Controller

yes if the camera has power, I powered mine with the back up lights so it will not function that way.

Yes and no. The better question is how the solar will be getting set up. If you use your panel to charge a battery and use the battery itself to power the light, then you will be golden, the panels will absorb what they need during day so when it gets dark the light can keep going off of the battery reserve. If you wanted to hook the light directly up to the panels THEN you would need the full 250watts, and it would only work in direct sunlight, you see? the goal is not to have enough power strictly from solar panels, but to have enough to charge a battery with the panels and use the battery with an inverter to power intended devices. Long answer short, buy a cheap deep cycle battery to hook an inverter up to, and hook your light up to said inverter, with this set up your light should work just fine. Hope that helps virtual pal.

Greetings,The solar powered light fixture has three settings: off, auto (activated by the motion sensor) and smart (dusk to dawn). When turned on, the fixture is controlled by the light sensor, so the fixture will only work in dark or low-light conditions. This fixture puts out quite a bit of light; if you plan to use it as a night light, I think there are better options available.I hope this information helps.

Yes, there is built in backup. I don't know how long it will last, but definitely long enough for the typical power outage. Mine has been unplugged for over a day now and the display is still working (unlike the timer itself, which is permanently off, and ready for recyling).

Yes you can ! Power drain is very low . You will have to have the trailer plug connected and the lights on .

You can't unless you get the blessing from your local utility company. If you do,it would take a little more watts than the unit provides. Works when the sun shines only.

No. To save on battery power, it only lights when buttons are pressed. I prefer to have even THAT option disabled. I have flashlights to supply power during outages. If you'd like to get one, go here; http://lightsngear.com

Yes. It comes on at dusk and shuts off in the morning. Make sure you have it in a spot that it will get enough sunlight to keep a charge. The power is stored in the solar batteries. So far they have kept their charge well. I have had to change batteries in my other solar lights. They need plenty of light to hold a charge. They emit a very suttle light. Not alot but just enough to light a pathway. Because they are flat on the top, they will collect snow which will put pressure on the bracket and the gutter so I am going to put mine away for the winter.

Hi, I hear you, they didn't make it easy - especially to wire the backup power supply on the side pins. Just treat it as if it is simply wires in line - red (plus) from source to red of battery, and the same for black. For the side pins - backup battery to keep the data on screen when source power is low - like at night for solar supplies, just connect negative to top pin and positive to second pin - it must be a minimum of 3v to work and will drain a 9v battery in about 3 days. Good luck!

the battery is for backup only..... in case electricity goes out. You still need to wire it.
