Awesome Portable, foldable Solar panels.... I am always looking to find Solar panels that cost under $1 per watt but the portability + Charge Controller makes this a pretty good deal.
I have recently learned that it is a good idea to have a few options and kits for redundancy when something like a Hurricane or a Tornado hits and blows all your above ground Solar panels into the ocean. A few solar, dynamo radios and solar lamps is also a very good idea. Be prepared for the worst.
This solar panel packs 100W of power yet is only 0.2 in thick and weighs only 5.2 lbs., making it easier to transport, hang, and remove.
The panel is protected in a thick fabric case.... easy to carry and Ideal to use for camping, camping, climbing, hiking, picnic, charging your car battery, or in emergencies .
With High efficiency monocrystalline solar cell, you will get greater power efficiency even though the panel is smaller than a traditional model.
Solar Controller : 10A for all 12V batteries (Series circuit to charge 24V, 36V or 48V) with its 18V optimum power voltage.
