I'm passing this on for our friends north of the border and those in
the US near the border.
I''ve noticed that Canadian Tire runs some decent sales on solar panels
from time to time.
At present, I see that the "Eliminator Solar Panel, 15 Watt," Product#
11-1882-8, is on sale at Canadian Tire for $99.99 Canadian, just about
$87 US.
I have no experience with these, just what I read in the listing
See http://www.canadiantire.ca and search on "solar panel".

I have one of these for my cottage trailer. A friend of mine used an identical
one for his SDHW setup. Then he got a 'real' (BP) panel. His DC pump now pumps
much quicker, and starts about 3/4 hr earlier in the day, runs about another 3/4
later, and doesn't slow down so much when a cloud passes by.
I won't be buying another one.
Oh. I understand that Canadian Tire has stopped using ICP panels and will be
buying panels from Japan. I suspect this is an end-of-line clearance sale.

Yep, usually for SDHW, for instance the Thermo-Dynamics stuff, they
recommend a 25ish watt panel, with the little capacitor box to get it
bumping along on hazy days.
Have to be careful, though, in using larger panels for that. SDHW
systems that use panels instead of differential temperature controllers
are "calibrated" to a particular panel size, when the big thermal panel
is "hot", there is a corresponding availability of solar insolation to
run the pump, and the pump is running at the appropriate flow rate to
give optimal "residence time" of the water or glycol in the solar
manifold.
With an oversized panel on the pump, you'll be running outside the
"calibration zone" of the equipment, and may end up throwing heat
instead of making any.
Sounds like, though, that your friend is still probably safe, and
probably closer to optimum than the 15watt was giving him.
