In September 2008 I took the module in 12 weeks of the ASBL " Workshops Street Voot "in Woluwe. 1 year and a half waiting list!
This workshop consists of a theoretical and practical course for the realization of sensor planes. One that produces hot water then. What
interest to build it myself? Apart from the pleasure of tinkering recess, after the region where you are (Flanders, Wallonia and Brussels Capital) premiums in force and type of dwelling (existing or new), it may be more financially attractive to the installation yourself or with a qualified professional SOLTHERM.
I would add that there 's interest anyway for the planet.
In our situation it was more interesting anyway because the tax cut was already fully puff by photovoltaic panels.
For installation, the trainer and participants form a support network to install the panels. Free.
Speaking figure, the price of materials goes back about 50% of panels purchased in commerce and labor, as I have explained, for free.
(... will explain how a small non-profit organization comes at a price like without creating a volume equivalent to the professional production of medium) Let
, yesterday we started to prepare the components of the flat plate of 8 sqm draining to be integrated into the roof. Besides the advantage of the aesthetic (which is not a priority in my case) the solar integrated roof is a little more efficient.
The system here does not contain water glycol, which is also a great advantage for the maintenance, and especially nature.
Just because you take the roof insulation of greater thickness as it was boxed. And also because it is 'cool' because it is slower no natural ventilation behind the sensor, since it is integrated.
Unlike the PV for this performance drop when the temp rises. The fins are
3.30 m long. The supplier of fins failed to deliver because we failed machine. So we soldered to the fins together and solder it fct perfectly. Furthermore, it was valued falling another site.
The fins are not made 'home', but from a manufacturer of solar collectors. The technology is the same and yields well.
Here are some photos from the day of preparation. We cut the extruded aluminum, welded to the 18 fins 3 absorbers, and directed the leak test by placing the absorber at 6 bar pressure. A single weld had to be redone, and it was not mine! ;-) By cons I'm burned! ... And it's probably because I made fun of him who had missed the weld ... ;-)
I hope to find time to do a blog devoted to its panels and system draining.
The control system also made it through the association. In fact John is Motlo electronics and has designed its small controller and proposes to just 100 € for the manufacture'm even too.
