Because of following advantages concentrating type collector are used in solar power plant: -
1. Temperature: Temperature obtained is high because absorber area is less and collector/reflector area is more. 2. Heat Losses: Losses are less as absorber area is small 3. Efficiency: Efficiency is high 4. Heat insulation: Heat insulation required is less as absorber area is small. 5. Anti-freeze protection: Little or no anti-freeze protection is required to protect the absorber. 6. Used to generate steam electricity: Can be used to generate electricity with the help of steam turbine. 7. Due to tracking better results: As tracking system is used better results are obtain than flat type collector.
