What is a Solar Parabolic Dish?
A Solar Parabolic Dish is a type of Solar Collector that uses a parabolic reflector to focus sunlight onto a central receiver, where the solar energy is absorbed and converted into heat.
It accomplishes this through the use of a computer and dual-axis tracking. In the front area of the dish, the receiver is frequently mounted at the focal point.
Components of a Solar Parabolic Dish
The Parabolic Dish is made up of three main components:
The components of a Solar Parabolic Dish include the solar reflector, solar receiver, and the supporting structure.
Solar Reflector Dish
The Solar Reflector is the parabolic-shaped dish that focuses sunlight onto the receiver, which gathers the solar energy directly from its source.
The Paraboloid Reflector is a curved surface shaped like half a parabola. It is often made of a reflective material, such as aluminum, that will reflect and focus sunlight onto the receiver.
Receiver
It is the central element in Parabolic Dish Solar Collectors, which is mounted at the focal point of the Solar Reflector and absorbs and collects solar heat from the reflector.
The absorbed solar energy is then converted into heat, which can be used to generate electricity or for other purposes.
Solar collectors may be composed of copper- or aluminum-based absorbers and use fluid to transfer the solar heat.
Supporting Structure
The support structure serves as a mounting point for the Paraboloid Reflector and Solar Receiver Tube, providing a stable base for holding components in place.
It must be strong enough to support the weight of the Solar Reflector and Receiver and any wind load that may be exerted on it.
Likewise, it tracks the sunlight during the day to effectively reflect the sunlight to the receiver.
How It Works
Solar Parabolic Dishes work by focusing sunlight onto a central receiver, where it is absorbed and transformed into heat using a parabolic reflector.
The parabolic dish has two (2) functions: either collecting or refracting solar energy. This process is facilitated by the vertex, an antenna that is often found at the center of the dish.
When the reflector collects the solar energy and concentrates at the Parabolic Dish focus, it will then be delivered as thermal energy to the receiver. Using the geometric property of a parabola, the following is observed:
- When the angle of incidence and the angle of reflection are equal, incoming rays that are parallel to the dish are allowed to be focused on the vertex.
Energy sources such as sound, light, and radio waves are collected or reflected by parabolic dishes.
Benefits of Solar Parabolic Dishes
Solar Parabolic Dishes offer a number of advantages over other solar technologies, including:
Maximize Harvesting of Solar Energy
Solar parabolic dishes are able to track the sun across the sky throughout the day, allowing them to maximize the amount of solar energy they collect.
High Conversion Efficiency
The efficiency of parabolic dish systems in converting solar energy to electricity is well recognized, making them an ideal renewable energy source.
That is due to the fact that the systems can withstand temperatures of up to 1000 degrees Celsius at the receiver while maintaining excellent conversion efficiency within a limited power range.
Scalable
Solar Parabolic Dishes are scalable, meaning they can be designed to meet the specific needs of a customer. They are often used in large solar power plants where a large amount of energy is needed.
It also offers a great deal of flexibility in terms of its design and installation. They can be installed on the ground or on rooftops and can be used in a variety of Solar PV applications.
Low Water Usage
Solar Parabolic Dishes require very little to no water for operation and for cooling, making them a more environmentally-friendly option than other solar technologies.
