Lower ends of the vertical and inclined piles are attached to a concrete base or rammed into a ground, and the upper ends are attached to each other so that the base and piles form a triangle. The vertical pile raises an upper edge of a collector and the inclined pile supports a back side of the collector, when the back side leans on it, and provides a desired inclination for the collector.
- A collector is lifted directly in its position on the supports, which are arranged on the ground so that the inclined piles locate usually approx. ¼ from each collector side, and attached to the piles. The supports are installed at high pace so that it is difficult for a vehicle with a crane to move between the supports and it needs an extra caution and work to position collectors on the supports.
- The adjacent and positioned collectors are connected to each other by corner-to-corner connections, which are provided by 180 degrees bended external flexible metal hoses, whereupon a minimum space between collectors can be approx. 150-200 mm because of the characteristic of the hoses and collector alignment tolerances. The hoses provides external compensation for thermal expansion, but those need a dedicated external hose insulation and protection material.

The tubes are installed at least partly inside the collector and at least one of the tubes comprises a flexible part inside the collector.
- The term “hydraulic connection tube(s)” refers to hydraulic connection means, which can be e.g. a tube, hose, or any other hollow, elongated element (body) that can be used for conveying heat transport fluids used in solar thermal collectors. The means are made of e.g. at least one of the following materials: metal, plastic, and rubber.

FIGS. 1a-1e illustrates a T-shaped mounting support and a sliding of a solar thermal collector along the support during a mounting, and -
FIGS. 2a-2c illustrates a flexible hydraulic connection tubes. -
FIG. 1a illustrates two adjacent large area solarthermal collectors collectors - The
lower supports 100 are configured to supportlower parts collectors upper supports 100, for one, are configured to supportupper parts - The use of the
supports 100 reduces a number of required supports by repositioning them to a far side of eachcollector support 100 can be shared by twoadjacent collectors -

support 100 comprises a C-shaped, I-shaped or other type ofvertical support part 120 that has abottom end 122 and atop end 124. Thebottom end 122 is configured to be mounted into the ground or a mounting base e.g. a concrete or metal base. - The
support 100 further comprises aninclination part 130, which is attached to thetop end 124. It comprises aninclined surface 132 to which a C-shaped, I-shaped of other type ofhorizontal support part 140 is attached in order to form the T-shaped support 100. It is possible to use more than oneparts 120 to support thepart 140. -
FIG. 1c illustrates onecollector 110 b that is mounted on thesupport 100. Thesupport 100 can be e.g. a shared support, which can support e.g. twocollectors 110, 110 b. - The
part 140 is configured to support the collector(s) 110 a, 110 b and enables to slide one supportedcollector 110 a—after it has been lifted on thesupports 100 asFIG. 1d illustrates—along thepart 140 in a horizontal direction e.g. towards the supportedcollector 110 b in order to mount the collector(s) 110 a, 110 b according toFIG. 1 e. The mounted collector(s) 110 a, 110 b is inclined according to theinclined surface 132. - The supported and positioned
collectors FIGS. 2a -2 c. - With the sufficiently flexible hydraulic connection, it is possible to make an ultra-short, e.g. approx. 20-40 mm, collector-to-collector mounting distance, which together with the shared
support 100 provides a significantly, e.g. almost 50%, reduced number of piles. - The supported collector(s) 110 a, 110 b is attached to the
part 140, which comprises at least onemounting hole 142, e.g. at least one elongated hole, by means of attachingmeans 150, which comprise e.g. an attaching support (attaching bracket) 150, e.g. an L-shaped steel plate (bracket), and a screw-nut combination for eachsupport 150. - The support(s) 150 is installed on a
back side collector frame 111, and attached by the screw-nut combination(s) through thehole 142.

The support(s) 150 prevents a movement of the supportedcollector - The T-shaped supports 100 ensure good alignment between the
adjacent collectors - In addition, the
supports 100 provides nice visual appearance when the collector row can easily be made to smoothly follow the height profile of the ground. - In addition, the collector row with

The heat transport channel comprises an internal access (an internal inlet) and an internal exit (an internal outlet) inside thecollector 200. - The
frame 220 comprises an access hole (an inlet hole) and an exit hole (an outlet hole), which enable thehydraulic connection frame 220 can be either aligned or offset from the internal access and exit on theabsorber 210. The access and exit holes can be located e.g. in a middle of side frames (side walls) 222 a, 222 b of theframe 220 and the internal access and exit can be located e.g. in corners of theframe 220 asFIGS. 2a-2c illustrate. - The
collector 200 does not have significant external connections, whereupon there is no shadow effect on a next collector row behind from thehydraulic connections - In addition, a wind load on the collector row under stormy conditions is reduced, because of the absence of the significant external connections, which eases requirements on the mechanical support system.
- In addition, a highest part of the installation is a top frame (top wall) 224, which eases an integration with the landscape and promotes an approval of new solar fields.
- In addition, the offsets removes a need for having the
hydraulic connection 230, 232 (access and exit holes) near collector corners, which reduces mechanical weakening of the corners, when the internal access and exit in upper corners of theabsorber 210 are maintained. This provides no issues with captured air during filling of theabsorber 210. - In addition, the height of the
hydraulic connection hydraulic connections - Alternatively, it is possible that the access and exit holes locate in e.g. the
top frame 224 or anywhere else of thecollector 200. - The
hydraulic connection hydraulic connection tubes collector 200, through the access and exit holes. Thetubes collector 200 and at least one of thetubes collector 200, whereupon it can be bended inside thecollector 200. - One of the

So, the tube(s) 230, 232 can be a flexible metal and/or plastic tube (hose) 230, 232 at least partly. - The integrated tube(s) 230, 232 reduces tube bending, whereupon a flexible tube installation is now with reduced mechanical loading of the tubes (hoses) 230, 232.
- The
tube 230 comprises aninlet connection adapter 234 and thetube 232 comprises anoutlet connection adapter 236 for connecting thetubes adapter 236 of onecollector 200 is connected to its counterpart, i.e. theadapter 234 of the another collector 200 (heat transport channel), and so on. - The
tubes collector 200 instead f two, whereupon it reduces significantly an installation time when the interconnection between thecollectors 200 is simple: the collector mounting and hydraulic connection is now a single step operation. It is also possible to realize solutions, which comprises two connections of similar types, e.g. two of thetube 230 or thetube 232. - In addition, the
tubes absorber 210. - In addition, the
collector 200 enables in-production tube test, when only one field-tested adapter connection per thecollector 200. Thus, fewer in-field connections are required and, so, the risk of in-field introduced connection leaks is reduced. - The adapter(s) 234, 236 comprises a transport position for protecting the adapter(s) 234, 236 during transportation. The adapter(s) 234, 236 is pulled out from the transport position for the
hydraulic connection collector 200 during its connection. - The
integrated tubes supports 100 an ultra-short distance, approx. 20-40 mm, between theadjacent collector 200 by the increased mechanical flexibility of thehydraulic connection - Due to the short collector distance, minimal fraction of the
hydraulic connection - In addition,
tubes - In addition,
tubes collectors 200. The visual appearance is now similar to that of widely used large scale photovoltaic (PV) installations, whereupon a seamless visual integration with PV installations is possible. - The invention has been now explained above with reference to the aforesaid embodiments and the several advantages of the invention have been demonstrated.
- It is clear that the invention is not only restricted to these embodiments, but comprises all possible embodiments within the scope of the invention thought and the following claims.
