III. How to mount the collector on an external wall
The requirement to the wall body for mounting the collector on external wall:
The loadability of the external wall shall be 2 times the total mass of the collector loaded fully with water and
there shouldn't be any deformation, crack or chip on the wall body. Its loadability shall be confirmed through
tests. In addition to its loadability to the solar collector, the necessary technical measures shall be taken to
treat the locations where the collector will be mounted, so as to prevent the disadvantages to the wall body,
such as deforming or cracks, etc.
The light-weight filled wall shall not be used as a structure to support the solar collector.
The support of the collector mounted on the external wall shall be fixed onto the built-in connector in the
wall firmly. A concrete structural column could be added at the place o the built-in connector if necessary,
and it shall meet the requirement of anticorrosion.
There are two ways for mounting the plate collector onto the external wall, depending on the angle between
the plate collector and the external wall.
● Mount the plate collector onto the wall vertically;
● Mount the plate collector onto the wall not vertically;
