Well..... I'm going to do a bit of speculating here, but if someone makes a
12VDC block heater, it should be able to be connected to a typical 12VDC
solar panel.  I'd guess that the problem will be the amount of power required
to create a reasonable amount of heat will exceed the power output of  a
moderately sized solar panel.  Typical solar panels (2' x 2' to 2' x 4')
create only a peak of about 10 to 20 Watts.  A large outdoor Christmas light
bulb consumes about 9 Watts.  Just going on gut-feel instinct, I doubt that 1
or 2 Christmas lights could keep your engine very warm in very cold
temperatures.  I'm sure that a block heater would be more efficient at
changing electricity into heat than a light bulb, but I still doubt that you
could create enough power from the solar panels.  To find out, track down a
12VDC block heater (if one exists) and see how much power it draws.  I'd
guess 100 to 200 Watts.  Compare this to the amount of power provided by the
solar panel you find and you'll have the answer.

How about a diesel powered block heater??   Just keep the engine running.  :)

Good luck,
