Cor, that seems like a rather small collector. Is it large enough that
you got a significant benefit from it?
My experience is even more basic. We have south facing windows on our
upper
charging. By
offsetting your home heating with a solar collector design, you could
free up funds to install more PV panels :)

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

The supposed national average home electrical use is about 900 to 1000

in Wisconsin (where we have been having high temps of below zero or the low
single digits for the past week). We have less than 5kw of PVs mostly
It is possible to go all electric, even in MN, but it requires different
house construction. Bob Ramlow lives in Wisconsin and says his solar hot

Again, just as with EVs, it's not going to be an universal solution. But, again
again, even a partial solution is going to make sense for lots of folks.
Somebody who really does need a diesel pickup to haul stuff around on a regular

However, you are very lucky that your peak need correlates exactly with your

think Robert's assertions are largely correct. Our peak needs correspond with
the season of least generation. The temperature gap in summer

True, and anyone who thinks higher efficiency is just around the corner
