How to Properly Mount an Evacuated Tube Solar Collector How to Properly Mount an Evacuated Tube Solar Collector

What You'll Need
Collector frame (2 side rails and a top and bottom support assembly)
Vacuum tubes (collector tubes)
Rubber cap
Reflectors
Plastic clips for special fixings
Silicon grease

Evacuated tube solar collectors are now being used by many due to its efficiency in achieving very high temperatures. These are now commonly used for commercial and industrial heating applications and also became a good substitute for flat-plate collectors for domestic space heating. To give you a view of what an evacuated tube solar collector looks like, it is basically containing various rows of glass tubes which are connected to a header pipe. This solar collector comes in different types namely; Evacuated Tube  Collectors, Heat Pipe Evacuated Tube Collectors and Integrated Tank Solar Collectors. Regardless of the type, evacuated tube solar collector must be mounted properly.

Step 1 – Assemble the Frame

The collector frame used for this process is made from stainless steel which are designed for fast and easy installation. Like how most of the professional installers did with attaching the frame, you directly drill through the tiles and attach them with the use of coach screws into the rafter. You need to assemble the uprights of the collector frame. Once the uprights are assembled, attach the manifold and secure it with a Manifold Fixing Loop. You need to make sure that the collector will be secured with screws. Now the lower tube track should also be attached to the protrusions which are found at the base of the uprights. Another set of screws but long ones are needed to fix the attachment.

Step 2 – Install the Collector Tubes or the Vacuum Tubes

You can find several tubes here but only place the rubber cap at the end of the first evacuated tube. To easily insert the top of the evacuated tube into the manifold, you need to apply some silicon grease and then secure its end to the frame bar. Once you’re done with the first tube, just continue doing the same process to the rest of the tubes. As you install the tubes, make sure that they are covered and secured. You will only be removing the cover when you are going to use it.

Step 3 – Install the Reflector

To maximize every amount of sunlight coming into the tubes, reflectors should be properly assembled. If not properly installed, a huge amount of sunlight falling into the tubes will just be wasted. One example of a reflector is one which has 19 pressed stainless forms which is needed to be attached to each tube with the use of the plastic clips. You need to begin by placing one section of the reflector between two vacuum tubes. There are special fixings like plastic clips which can be used at the end of the reflector. Insert these fixings and rotate about 90% while securing the other end of the reflector. The same with the tubes, repeat the procedure for the other remaining sections of the reflector.
