Anyone use Solarus panels before?

We all know that solar water heaters are significantly more efficient than PV panels. So it sounds about right, if you combine a single panel, generate some electricity and absorb the heat into water, you'll make at least 3 times the energy.

but that it "hot water energy" not electrical energy. My, and I guess most people's needs are a lot more towards electrical energy than hot was energy.

Agreed, but I'm willing to bet money on it that those people telling you that this is "4 times more efficient" was looking at the overall output, ie hot water (reverse-calculated at 1.16Wh/liter/Kelvin) plus the PV output. Then 4x is not that surprising.

Looking at PV output only... even a 50% improvement sounds too good to be true.
