UVAC Solar Receiver Has Heat Loss Levels Below 9%
Siemens announced the release of a new solar receiver, the UVAC 2010 (Universal Vacuum Air Collector), which further increases thermal heat production. The new UVAC 2010 is the next generation of the UVAC receiver, which is the key component for the solar fields of parabolic-trough power plants.
Using high-tech coatings, UVAC 2010 absorbs maximum solar energy and converts it into heat used to produce electricity. The power block and the solar field equipped with high-efficiency receivers are the key components of every parabolic-trough power plant. These power plants are the solar-based power generation technology with the best track record of all utility-scale solar technologies.
The UVAC 2010 features improved emissivity (heat loss) as a result of technological advances in the sputtered selective coatings, as well as an improved active area to length ratio, which enables greater solar exposure of the receiver and a proportionate increase in absorbed energy. Its superior heat loss levels — below 9% — provide developers with greater efficiency.
Until 2020, the market for solar thermal power plants will show annual double-digit growth rates and attain a volume of over EUR20 billion. In the future, the primary focal growth regions will be the U.S., South Africa, Australia, Spain, India, North Africa and the Middle East.
