Solar panel with built in battery: can't find one

Post by DoctorIknow » Sun Aug 02, 2009 7:38 pm

I saw one last week, but forgot to find out the manufacturer.

The panel is about 30 x 20 inches and about 2.5 inches thick, and very heavy as there is a battery pack behind the entire panel. I don't know if it has a built in 120v inverter, but I really don't need that,,,,just a 12v output.

I love the idea on NOT running anything off my car battery and using a panel (plenty of those with 12v outputs!) to charge the car battery.

An hour of searching on google yielded nada..

Anyone know of this panel with built-in battery?

Thanks

Real Goods does have a big one with a 12v battery all mounted on a cart ($3700) and a small one with a lithium battery inside ($69), so obviously, I wasn't the first to think how nice it would be to have portability for a power source. And the fact there can be power during off-sun times is a huge reason for these products!

All the other "chargers" or panels I've found require any electrical device to be tethered to a big battery or home/RV/car. I don't need that much juice, just enough to power some great old RadioShack 10 watt self-powered speakers, inverter and ipod charger that are all sequestered in a portable unit. There portable boom box (that can eat 8 alkaline "D" batteries in no time!) that can come near this setup in db output, and if there was, it would be huge and probably butt ugly, too.

Are you speaking of the Coleman CL3900? I believe they are 60 watt. They are battery chargers and have an inverter. They cost about $350 I think and are available at camping world I believe or Costco.
Typically we use then along with a serious of car batteries.

If you get nicad D cells, note that most are not D cells.
Look at the capacity.
They should be close to 10,000 mah.
Most are AA cells.

I appreciate the links and help, but none of those items is what I'm looking for.

Let me try once more with brevity this time:

-----A solar panel, about 2 x 3 feet
-----The panel is mounted in a sturdy frame about 2.5 or 3 inches thick
-----The frame is stuffed with a battery or a series of batteries.
-----The panel/battery combo is stand alone.

If real goods doesn't have it, I don't know where to look.

It's an odd approach as batteries usually are kept out of the sun.
You might call them and see if they know.

I have seen some small items that are self contained and even have some going on ebay, but nothing of the size you describe.
