ABSTRACT:
A method of manufacturing an integral one-piece solar collector panel10by a rotational moulding process is disclosed. The solar collector panel10has a plurality of fluid ways15extending between opposed ends18, 19and transverse headers18, 19opening into the open ends of the fluid ways15. The panel10is moulded by a rotational moulding process using mould faces with a non planar topography, eg in the form of a plurality of lines projecting outwardly proud of the remainder of the mould plate. This enables areas of the moulded body12to be formed that are not hollow and form a solid wall in the moulded panel and other areas of the body to be formed that are hollow and form the fluid ways15and headers18, 19. After the moulding of the panel10has taken place the two opposed mould faces are moved towards each other to cause the contacting layers of mould material to firmly adhere to each other.
