When I took a Solar Energy course way back when, my instructor said
there was a rule of thumb for solar thermal heating. He said to take
the square footage of the heated **area** and divide by 3 to produce a
storage **volume** estimate. At the time, fist sized rocks were used
to store the
I think a combo of PV panels and solar collectors would generally be the
best solution, assuming you have the sun exposure. Currently PVs are
not very efficient. I don't have any numbers of solar collectors but
I'm pretty sure they can beat PVs several times over.
Since home heating doesn't
I am surprised this questions did not get more answers.
I am not an authority, but have been observing these motors for 20
years. We really can't talk about the Voltage across the motor
without talking about RPM and Amperage. If you tried to put 170V
across the Motor with less than 500 RPM,

I like PV a lot, in fact I wrote an article about PV on my RV that was
published in Home Power, but isn't this list supposed to talk/discuss EV's?
The EVDL conventions say, Discussions of PV (solar) energy should be
tightly framed in an EV
