A new type of solar concentrator employing a cone-cylinder combination
Most conventional solar thermal radiation concentrators have some sort of symmetry which allows them to concentrate solar thermal energy for their operation. We report a new system that utilises the symmetry of a cone and a cylinder combination to simulate the concentration of solar radiation on a ring containing a fluid (water). A halogen lamp is used as the source of radiation to simulate solar ...

Solar Thermal Power Plants
THE BENEFITS OF SOLAR THERMAL POWER PLANTS Solar thermal energy production requires two main things: sunlight and equipment to capture, store and disperse the energy. Only two types of solar thermal systems exist. They are the passive systems, which do not require equipment (such as the heat build-up in your car whenever you park it in the sun), and active systems which require a method to ...

Solar energy based thermal energy storage system using phase change materials
Nowadays for solar heating applications, usage of phase change materials (PCM) to store the heat in the form of latent heat is increased, because large quantity of thermal energy is stored in small volume. The present experimental investigation on the thermal energy storage (TES) system is developed using paraffin and stearic acid as PCM. In the present system solar energy is used as heat source ...

Flat absorbers with trapezoidal cavity for Fresnel reflecting solar concentrator
The absorber is a very important component of the solar concentrating collector. The overall heat loss coefficient of the flat rectangular absorber and multi-tube absorber were studied experimentally. Both absorbers were coated with ordinary dull black paint. The heat loss coefficient was comparatively 4-11% lower in the case of round pipe absorber and increased with the absorber temperature in ...
