I have been going about it backwards, trying to choose a system based
on the charging documents at

http://www.odysseyfactory.com/support.htm

The battery is a PC1200 (44Ah).

On a recent trip I discharged the battery in 2 days. So, I would
estimate that my usage is about 150Ah per week. I need to find a
system that will keep up with that rate of usage, and will meet the
minimum requirements of the odyssey PC2100. The best solution seems
to be an 80W panel, but based on the odyssey docs, that will not
bring the battery out of deep discharge. I guess that's when I'll
start the engine. Which begs another question, how much current does
the alternator put out with the engine at idle?

thanks,
andy
