Abstract:
Renewable energy is clean energy that does not produce pollutants that cause global warming. One of the examples is solar energy. Solar energy is the largest renewable energy source that can be used in all regions of the world and is available every day which makes it possible to generate a lot of electricity. Therefore, technology is needed that can optimally utilize this renewable energy. In this project, the parabolic trough solar collector is combined with a solar dish collector to achieve higher thermal efficiency compared to the parabolic trough only electricity generation. The solar field area is also calculated because of solar dish collector has a large solar field area. The result of thermal efficiency and solar field area is compared to parabolic trough only and solar dish only electricity generation. Three cases of these electricity generations are using a simple Rankine cycle with a steady-flow system and 5-MW capacity. The thermal efficiency of the parabolic trough-solar dish electricity generation improves by 2% and mid-range of solar field area compare to the other electricity generation.
