Components of a Solar Parabolic Dish
Depending on the physical size and the required thermal energy output, the dish can be installed in the garden, on a flat roof, or on a gable end of a building.
The larger dishes however are quite bulky because of the solar tracking mechanism and the size and weight of the absorber and the water heating component.
We shall therefore look at the components of a solar parabolic dish which is installed in the garden grounds.
This is usually fabricated from steel tubular sections, and incorporates the lateral and tilting solar tracking mechanism which follows the path of the sun across the sky. The support frame can be secured to a concrete pad or brick up-stands by high tensile foundation bolts, facing south.
The Solar Parabolic Dish
A latticed steel column supports the central focus point absorber and thermal energy component. This support is fixed the rear of the dish at its north edge, so as not to block any incoming solar light. It is bolted at the base of this column to the main tubular supports frame.
Solar Tracking Device
The tracking mechanisms, which can be electrically, pneumatically, or hydraulically operated, are connected to the dish support frame by adjustable arms for optimum primary settings and bolted to the main frame supports.
