Yes a swimming pool, a spa ... or a thermal buffer of several m3 ... or supply the neighbor with DHW (but that the "system" does not want) ...
Not bad the idea of reflecto but I would limit it to reflection in winter and not the cover, for the cover just draw a flexible material covering (white preferably) ... which would simplify the movement and therefore the size and cost of installation.
In fact he took over the concept of the Ulog solar oven: Solar-thermal / solar-oven cooker-ulog-build-and-performance-t10753.html
And that reminds me strongly of the idea developed here by Flytox (in 2009): heating-insulation / house-double-southeast t7157.html
ps: uh say he's on the other side? I have a doubt ...

But that would make two separate systems (so two engines, and perhaps difficulties to mechanically coexist the two systems).Christophe wrote:Not bad the idea of reflecto but I would limit it to reflection in winter and not the cover, for the cover just draw a flexible material covering (white preferably) ... which would simplify the movement and therefore the size and cost of installation.

Re: solar ECS - over-production ?!
Certainly it is easier, mechanically, to unwind a blind than to flip mirrors (heavy, brittle ...)
I believe that the "double south" function in this system is more interesting than the "sun cover" function ...

The fact that it can do both without additional complication seems interesting.Christophe wrote:I believe that the "double south" function in this system is more interesting than the "sun cover" function ...

Re: solar ECS - over-production ?!
I think that partially hiding the panels is quite easy to do, indeed with a motorized "shutter" a bit like the skylight shutters.
To improve performance in the winter, perhaps fresnel lenses can bring a little more.

Re: solar ECS - over-production ?!
Fresnel lenses only concentrate on a smaller area, which would imply dimensions much greater than those of the receiver panels, which seems to me quite difficult in practice ...

It is much heavier and more complicated than the reflector system.

Re: solar ECS - over-production ?!
Hello,
I installed a reflector-occultant (non-motorized) there is a little more than 2ans and a half (soon 3 ...): http://www.apper-solaire.org/Pages/Expe ... occultant/
and I was already at the time largely inspired by this montage that I found very clever: http://www.apper-solaire.org/Pages/Expe ... /index.pdf
I thank again its author.

even with one lens per cell?

I was thinking more about the fresnel lenses we put on the panel, one per cell, for example.
