[HCARC] question about repeater

[Gary Johnson N5BAA]

Yes, I agree to a point, but since the solar part of the system is just for 
backup for hopefully a short period of time, the solar panel needed has 
plenty of time to perform battery charging.  It's akin to the solar setup 
needed for daily operation vs the solar setup one might put at a vacation 
house where it was only operated 2 weekends a month.  The requirements are 
radically different.  To determine what we would need to run the system full 
time off of solar would best be found by putting one of those plug in watt 
meters into the current system and see over a couple of weeks what our 
average daily electrical usage is.  That info tells you how much electricity 
you need to be able to generate.  Remember going solar, while it has an up 
front cost, eliminates the electric bill monthly so in effect it pays for 
itself over time.  The cost of solar is going down significantly over time.

Thanks for the lead to the local Golf Cart guys.  I'll check them out - the 
225 amp hour 6 volt battery at Costco was $89.00 (two required to get 12 
volts cost $178.00).  Since I have a standing appointment every tuesday in 
SA, the trip into town cost is negligible.
