Depending on where your remote beacon is located, you might need to consider temperature extremes.  Both low and high temperature extremes affect the efficiency of both solar panels and batteries (on discharge and charging).  If you have fairly normal temperatures, I would not worry too much but if you are operating with below freezing or very hot environments then you need to look at the various curves that show how the solar panel or battery charging efficiency degrades.

Well, Sir, I am on a similar mission with an eye to alternative energy, and also am wanting to spend budgeted $ carefully.

Thus far, my meanderings have uncovered Harbor Freight Tools selling the most affordable solar panels, which are designed to be hooked up and added units to as time and $ afford.

To get the recommended 100 watts of output from solar panels, you would have to drop about $440 (+S&H,tax, etc.) for two 45 watt panel kits, item #90599-8VGA.

Web address for above, if you want to get a gander:

http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=90599

On this link, you can click on "download product manual" if you want more info or to view specs.

As to the storage battery issues: I get golf cart batteries that are reconditioned via our local battery supplier.  

Don't know what you have available where you live, but I pay about $20 for a reconditioned golf cart battery, which would retail for about $80 new.  

To keep these used batteries going, they have devices you can build or purchase, which helps to keep the plates clean and active.  There used to be a Yahoo! group dedicated to DIY efforts, but could not locate it last time I checked.

As to the windpower angle, that is an expensive proposition, unless you build your own, and I mean like the WindWorks octahedral module tower built from used (free) antenna masts (170' of tubing required), with your own design blades, governor system and driving either a geared commercial generator (sold at places like HFT <Example:$299 for item #45416-1VGA rated at 10,000 WATTS MAX/7200 WATTS RATED BELT-DRIVEN GENERATOR HEAD>) or else whatever you can salvage in the way of vehicle alternators, and regulators to go with your own design windmachine.  

Mother Earth News sells $20(+S&H) plans for a rather primitive, low-power, vehicle alternator wind generator you can cobble together:

There are a few useful DIY how-tos on the market: "The Homebuilt Wind-Generated Electricity Handbook" and those like of author Hugh Piggott, (http://www.cat.org.uk/catpubs/catbooks.tmpl) but this is a hard way to go, unless you are a dedicated, stubborn, & dyed-in-the-wool inveterate DIY tinkerer like myself.

Hope some of this info is useful to you.  Your beacon project sounds intriguing!  Good Luck!

I have finally built a small wind generator.Hopefully it will be up and running soon.
