Everybody sees a deal out there online these days. And then, sometimes you think.. hmm will it work out? Should I risk it? What would other people think of it. Let's share some links and ideas, and ultimately if one person bites the bullet and tries it... share your experiences with others. That way we can follow or avoid good and bad paths. Obviously there are always pro's and cons. Please try to provide a bit of information or even a pic when possible. State whether you've actually tried it, or not. Ebay is a bit tough, it won't let you direct link to a picture I do not think, but pics can be saved and uploaded elsewhere - or - just add some description and those interested can click through and see it.

Here are a couple I am looking at. I like to set up remote projects away from my main solar setup, but if it is for a small shed or remote area, why break the bank?!

5 pcs for $14.17 shipped free

I think so too. I like setting up little remote light projects, solar. Where my cabin is, there are 58 acres. So, no shortage of remote locations, for example if we get working in the area we separate sand, from clay, and do mixing for cob. Nice to have light there when you get working past dark. And just security sorts of lights. My thoughts on the 9V panel is that you could run two LiION 3.6V batteries in series, which need about 8.4V to fully charge. Then Parallel enough of those series say 4 total, such that the delivered current was below any point that would risk the failure of the battery system. And for under $10. The 18650's have an over-voltage protect on them, and can accept a 500 mA charge. My thoughts are if 2 can handle an amp, a couple of hundred milliamps for 2 is not a huge risk. The more, the better tho - possible 6 total. 3 sets of 2 in series.

I've always liked these guys for project Solar Panels;
Nice, clean and shipped quickly.

Do compare pricing against them, some items I've better buys

I've dealt with them and have received what I ordered in 'good' condition.
For those interested... no spam, viruses and un-wanted phone calls because I have an account.

That's an interesting voltage too, 4.5V, uncommon. It's good to find different setups, for different uses.
