HI, a friend at work is interested in designing a solar energy system for his retirement home which he plans to have off-grid.

Propane heating with solar for appliances and such.

Anyone out there have any information on what they've tried, what works, what hasn't worked, etc?

Please email rblanken@ausd.net  Addressed to Rainer (Dr. Blankenhorn).

I know there are many among you who have a wealth of information to share.

Thanks!

Joan
