solar dish
Definition
Noun: A solar dish is a concave mirror designed to concentrate sunlight onto a single focal point. This concentration of solar energy can generate very high temperatures, making it useful for applications like generating steam for electricity or for high-temperature industrial processes.
Usage
The term "solar dish" is used to describe a specific type of solar thermal collector. It functions as a singular, standalone unit. * The research facility uses a large solar dish to test new materials under extreme heat. * A solar dish can be more efficient than flat solar panels for certain applications because it concentrates light.
Advanced Usage
- Technical Context: In engineering and renewable energy discussions, a "solar dish" is often part of a "solar dish Stirling system" or "dish engine system," where the concentrated heat drives a Stirling engine to produce electricity.
- The prototype combines a solar dish with a Stirling engine for off-grid power generation.
Variants and Related Words
- Solar Concentrator: A broader term for any device, including dishes, troughs, and towers, that concentrates sunlight.
- Parabolic Dish: A more technical term emphasizing the parabolic (concave) shape of the mirror.
- Dish Stirling System: A complete power system combining the solar dish with a Stirling engine.
Synonyms
- Parabolic Reflector
- Solar Concentrator (specific type)
Related Phrases
- To concentrate sunlight: This is the primary function of a solar dish.
- The mirror's shape allows it to concentrate sunlight with great intensity.
Noun
-
a concave mirror that concentrates the rays of the sun; can produce high temperatures
