    III. Introduction of the lightning arrestor Since collectors are mounted on roofs, they are vulnerable to lightning strikes. Therefore, they shall be mounted in the area which is well protected against lightning. If there isn’t any lightning arrestor, to protect the plate collector, a lightning rod or grounding line is required.

  • Page 9

    Notes: 1. If the building has a lightning arrestor, it shall be made sure by the local professional if the collector is well protected by the lightning arrestor. 2. If the collector can be protected, the frame mounted on-site shall be connected to the existing lightning belt with equipotential bonding.

    2. How to connect 3 plate collectors: To mount 3 plate collectors, the pipelines can be adjusted left and right according to the actual site conditions. The pipes and fittings shall be mounted in the same way for mounting two collectors above. 3.

  • Page 33

    The 2 Method: If the mounting area is limited, the collector array may be mounted in the following way. For this kind of array of collectors, 4 plate collectors shall be connected in parallel too and they are not put in one row. The pipes and fittings shall be mounted in the same way as mounting two collectors above.

  • Page 34

    The 3 Method: The kind of array of the collector needs less mounting area, but first two collectors shall be connected in parallel and then assemble two sets of the connected collectors in parallel too. The pipes and fittings shall be mounted in the same way for mounting two collectors above.
