Solar panel 135 l
This is the solar panel for hot water from Solaro. The 135 liter panel has 15 vacuum tubes (glass tubes).
The solar panel is mounted on the ground. It starts with mounting the frame. I realized how to fit the frame after a simple image that the instructions manually offered. After assembling the support, I tried to see what is the best position on the roof of the house. I continued with the assembly of the solar panel.
I mounted the 135 liter tank on top of the support and then the 5 liter assistant tank. I gave up the gasket that had to be between the tank and assistant tank because it remained a free space between them. It is not necessary to use that gasket, so I don't have to be worried.
I built a system that would allow me to climb the roof of the house so that I could mount the solar panel, after which I mounted the solar panel at the place provided. The only things that need to be done on the roof of houses are: installing the vacuum tubes and the connections with hot and cold water. The installation of the vacuum tubes was not too easy due to the uncomfortable position. Pressure should be exerted when the vacuum tube is inserted, until it passes by the gasket, so a lot of soap water should be used to help slide the vacuum tube on the gasket that is in the tank. Sprinkle with soap and water the gasket and the top of the vacuum tube. The heavy part at the introduction of the vacuum tube is at the beginning when a pressure should be exerted until the end passes. Then the vacuum tube should be pulled down and fixed in the bottom support. There are some gaskets that should not be forgotten because they protect from the dust in the top. The installation of the vacuum tubes is done in the evening after the sun sets, because they are heated very quickly from the sun's rays. The introduction of water is done in the morning before the sunrise. If the vacuum tubes are hot, at the introduction of cold water they can cling.
The assistant tank above the boiler has an input for cold water and an exit for the water overwhelming. The operating principle is similar to the WC tank. The water level in this assistant tank is only a few centimeters (maybe 10 cm).
It is a special place where a thermometer can be mounted.
When the water is very hot, some of it will be eliminated on a pipe above the boiler, to avoid the pressure that forms from the water steam.
Under the boiler is the exit for hot water. The pipe has 20mm.
And for the introduction of cold water in the boiler, the 16 mm pipe is used which carries the water from the source to the float vessel.
The frame must be fixed very well on the roof and that is why the rigor mostaries can be made to provide stability.
The structure of the roof must be sufficiently resistant to support the weight of the solar panel. At this solar panel, there are 135 liters of water plus 50 kg as weighs the system.
The 2 cold water pipes (16 mm) and hot water (20 mm) descend from the solar panel to the bathroom. A pressure reducer is mounted on the cold water pipe. The pressure reducer decreases the pressure that comes from the water network to the level at which the assistant tank can operate (2.5 bar) - I think there can be 3 bar. I mounted a tap on the 2 pipes so that I can stop the water cold and hot water in case of necessity. I mounted an exhaust tap, both on the hot water and the cold water - so I can remove the water from the panel in winter. When the water is emptied in the system, the water will remain in the vacuum tube, but the sun will evaporate the water from the vacuum tube in just a few minutes. So you don't have to worry about water in the vacuum tube. I used a reducer from 20 mm to 16 mm for hot water, because the installation in the bathroom works at 16 mm. The discounts should be made down because it is necessary for hot water to come with pressure.
The solar panel is somewhere 8 m above the house and offers pretty good pressure both at the sink and the shower.
