Solar parables in autoconstruction




by chrisleblay » 30/08/08, 01:34

Hello,

I created this thread to share, discuss news, find solutions on building
solar parables to his hot water free.

My results (more than positive):
http://www.actionclimatechange.com/para ... laire.html

I will regularly update this link has to follow my feedback

I went in search of solutions to rotate from east to west
I just sent an email to redrok.com to buy their LED system
to save time. I am also working on the thermal valves
to simplify to the maximum flow of hot water.
In this account I set the exit point
a hot water thermovanne that opens has a higher temperature or more 50C
Anyone know or can find it?
I am also looking for an "intelligent" 2-way thermovalve that would open
to get cold water in the main tank when
my solar container is empty. I did not find ca, help, ideas are welcome.

Hello,

Me being interested in the construction I can make you part of some tests.
First of all instead of heavy and bulky mirrors one can use "Reflect-a-Gro".
Reflectivity equal to or greater than a "standard" mirror.
Weight very interesting, comes in rolls fewer euros 10 1.2 or 1.4m m wide.
Works with "normal" tools.
(a little google => Reflect-a-Gro will give you sellers)

For the "pivot" of the dish, you can also use a rotating TV stand or even an accessory that you put on a car seat to help get out (see the different "trucks" that offer this gadget)

For your thermovalve search> 50 ° C I think you must find it on scrapped cars.
If I remember correctly, the engine cooling circuit "opens" only when a certain temperature is reached!

For the "intelligent" thermovalve see with the domestic plumbing material. I think a thermostatic mixer should do the trick.

Looking forward to reading you

Thank you Obelix, I talked with my neighbor also it looked skeptical but I'll go for a ride in the break to see these thermal valves.
Just complete the East West rotation sytem and it works well, AC can be also be used for solar panels.
I connected a timer on a System More TM1 which sends an electrical impusion second minimum 1, and the parable turns a few degrees.

Hello,

Taking the idea of ​​Buga I investigates a system with a chain and sprocket for a more powerful rotation of the same type:

To minimize the effort, I installed the "pan" on a wheel so there is no more effort in the center - I'm happy with this idea because it avoids the counterweight

Hello,
Here is another way to build a parable.
There 3 watching videos (part 1, 2 and 3)

great job but a question nagging me:
why make it complicated (parable with tracking system) when they can be simple (fixed level sensor) to make hot water.

To much hot water 50 °, flat plate collectors are perfect. But to get More 100 ° necessary for cooking, must concentrate the heat, for example with a device of the parable genre.

So no cooking, unless it is to cook the potatoes :D

Hello,

Thank you for the justemilieu refocusing the subject trying to build here a sort of guide for mounting a system for parabolic concentration toutlemonde mr.
Last thing: a picture is worth a thousand words!
To discuss versus DHW solar dish should open another thread.
