Renovation of a greenhouse (double glazing) with corrugated PVC sheets that have become opaque

[Napo dwarf]

in any case it is a good result;)

Christophe,

Could we fix solar panels instead of PMMA plates in the profiles you found?

[Christophe]

I had not seen the issue bernard ...

Yes if the spacing between 2 profiles is of the order of the width of a panel and the structure strong enough, no problem to fix something else on it.

Pkoi that?

[antoinet111]

to increase the inertia of your greenhouse you could paint the wall in black, it would capture the heat and restore it in the night.

the worst thing for a plant is the temperature shock, the day night deviations and the speed of descent in t ° is not great.

so this could smooth the curve, I think.

Because it would be a cheap solution to install solar panels. The real problem is that everything has to be rectangular.

Ben a greenhouse must be bright, PV panels are rather opaque ... even if there are "semi-transparent" (with less electrical power).

In recent months some installer / manufacturer of verandas offers with PV on the roof.

Only there's a catch ... = solar installation south and a south porch is almost uninhabitable in summer ... even with the vents that go well ... and if for any open in permanence , as do a terrace and pergola (with solar PV) ca will cost much cheaper

antoinet111, I had thought but a greenhouse should remain light ... and as it is oriented IS, not that inertia is interesting ... if not for increasing inertia, are not 36 solutions must put the material (soil, water ...) in the greenhouse ...

I had not seen this passage!

My dear Antoine is the temperature difference that make you fat partially vegetables, I do not know where you took the information but it is wrong!

Besides greenhouses stimulated this temperature change for a better performance!

The painting is finished, I would make you pictures as soon as there is a ray of sunshine

Dur, a year without sun

[Alain G]

I'm sure he went to take photos!

[Christophe]

Ok I admit I have a bit Lagé
Rooh veiled 3 photos taken at the moment!
Not too much sun seen earlier ... the windows have not been cleaned from the previous season (cherry tomatoes cut not enough jungle =)
The pipe is right for semi automatic arosage ...

Are the persistent moisture in the roof of polycarbonate plates (with aluminum closures it was even worse, I have transferred, if anyone has a reliable method I take! From aluminum tape or roof can be or Special scotch polyc plate, I saw that it was ... it's micro poreu ... it lets vapor but not water) ...
