New UVAC 6G receiver from Siemens boosts efficiency of solar thermal power plants

New UVAC 6G receiver from Siemens boosts efficiency of solar thermal power plants Siemens announced at the SolarPACES conference in Marrakech the release of a new solar receiver, the UVAC 6G (Universal Vacuum Air Collector), which further increases thermal heat production for solar power plants. The improved heat generation of the UVAC 6G enables the construction and operation of more efficient power plants that allows solar field operators to reduce capital and operating expenditures (CAPEX and OPEX) by up to 2.5 percent. Until now, more than 500.000 receivers of the UVAC family have been successfully installed in power plants.

The UVAC 6G is Siemens sixth generation solar receiver and features highest product durability based on Siemens long-term experience in this field. Using improved coatings, the UVAC 6G absorbs maximum solar energy and converts it into heat used to produce electricity. This new receiver generation allows the construction of more efficient solar fields, with reduced capital and operating expenditures by up to 2.5 percent. Patented getter bridge technology effectively eliminates hydrogen in the receiver tube before any vacuum loss can occur and does not require cost-intensive workaround solutions for maintenance.

"Based on our continuous R&D as well as our many years of field experience, the UVAC 6G expands the potential of solar thermal power plants with increased power generation capabilities," said Dr. Shmuel Fledel, CEO of Siemens Solar Thermal Energy Business Unit. "The UVAC 6G is also an extremely reliable product, which will provide our customers with many years of uninterrupted performance."

In fiscal 2011, revenue from the Siemens' Environmental Portfolio totaled about 30 billion, making Siemens one of the world's largest suppliers of ecofriendly technologies. In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by nearly 320 million tons, an amount equal to the total annual CO2 emissions of Berlin, Delhi, Hong Kong, Istanbul, London, New York, Singapore and Tokyo.

The Siemens Energy Sector is the world's leading supplier of a complete spectrum of products, services and solutions for power generation in thermal power plants and using renewables, power transmission in grids and for the extraction, processing and transport of oil and gas. In fiscal 2011 (ended September 30), the Energy Sector had revenues of EUR24.9 billion and received new orders totaling approximately EUR31.8 billion and posted a profit of EUR3.9 billion. On October 1, 2011, the Energy Sector had a work force of more than 82,000. Further information is available at:

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
