Read about ordering power tower solar mirror from the industry-leading mirror manufacturer, GreenTree Imports, Inc. A solar power tower, commonly referred to as the heliostat or central tower, is a solar furnace in which the tower receives and focuses sunlight.
Our Power Tower Solar Mirror can be mass produced and has a working life expectancy of 20 years. University of New South Wales (UNSW) solar researchers have converted more than 40% of the sunlight hitting a solar system into electricity, “the highest efficiency ever reported for sunlight conversion into electricity,” UNSW Scientia Professor and Director of the Australian Centre for Advanced Photovoltaics (ACAP) Professor Martin Green said. The researchers used Concentrated photovoltaic (CPV) technology, which uses optics such as lenses or curved mirrors to concentrate a large amount of sunlight in solar power towers.
A key part of the prototype’s design is the use of a custom optical bandpass filter to capture sunlight that is normally wasted by commercial solar cells on towers and convert it to electricity at a higher efficiency than the solar cells themselves ever could. The 40% efficiency milestone is the latest in a line of achievements by UNSW solar researchers spanning four decades. Compact power towers are being developed by Australian company RayGen Resources, which provided design and technical support for the high efficiency prototype. The 40% efficiency achievement is outlined in a paper expected to be published soon by the Progress in Photovoltaics journal. The result was achieved in outdoor tests in Sydney and independently confirmed by the National Renewable Energy Laboratory (NREL) at their outdoor test facility in the U.S. January 2, 2015 by DSM True, it is also compact and robust because you can put it deep underground in seismically stable areas where nothing and nobody can touch it. Solar will always be better for small isolated consumers, but it will always have trouble scaling to meet the needs of the mega-cities of the future. January 2, 2015 by Wrecks The way Lockheed-Martin are talking-up their fusion breakthrough claims, it can fit into a shipping container (or on a truck) and a 12MW unit can go into people’s backyard. January 2, 2015 by DSM Perhaps the G20 meeting had a briefing on that, but seeing your oil reserves value drop is only one reason for selling it off hard. Back yard fusion is a fantasy though, because it is dangerous to give individuals control over megawatts of energy even if the power unit is self contained. January 2, 2015 by DSM No, solar is not free because the gear to utilize it has a cost to produce and a finite life. I’d give it another 5 years for the cells and longer for the storage side of things, if you are talking about residential scale.
December 14, 2014 by TXjak How does this compare to the 44.7% reported ilast year? December 13, 2014 by Wrecks Well, they have boatloads of sunlight in Australia. December 9, 2014 by GatorALLin Always wondered if they could float a large lens like balloon to help capture a huge area and focus it to smaller points on the ground.
December 9, 2014 by Editor It’s a utility model, rather than home. December 8, 2014 by DSM There is a much better way to do this and it works at a small scale. Using the methods developed to fabricate 3D memory cells on chips one lays down rows of bragg gratings and walls where the wall is a layer of PV junctions with their band gap tuned to the spectrum of light falling on that part of the wall face.
December 9, 2014 by DSM Other than the prototype of that exact concept demonstrated early in 2016 by Prof. December 9, 2014 by pault01 It’s always nice to meet a time traveler.
December 9, 2014 by DSM Oh that, it is a style of music played by a Jazz group formed by some of the staff members at Mawson station, Antarctica. December 10, 2014 by DSM OK OK, just leave my Grandfather out of this, and can we keep this off the record because Xiuhtecuhtli has no sense of humour.
But it sounds like this would not really apply to handheld or residential solar systems, just for large power generation plants.
December 8, 2014 by DSM LOL no, coal and the associated gas deposits isn’t going anywhere until fusion is available. Huge LOL at the chlorophyll comment, plants are green because most of them do not utilise 30% of the spectrum at all.

Fine Tubes has been working with SENER for 4 years developing and producing the corrosion-resistant heat exchanger tubes for the steam generators as well as the high performance tubing that make up the receiver of the Gemasolar central tower - which is capable of absorbing 95% of radiation in the solar spectrum and transmitting this energy to be stored in the molten salt compound in its interior.


SENER has been working in the solar field industry since the 1980’s when the company was developing solar technology, including the first heliostats (mirrored panels which reflect sunlight).
The Gemasolar project itself began in 2006, when SENER designed and installed an experimental unit in the Almeria Solar Platform which demonstrated the validity of the receiver design and the molten salts system. The 185 hectare site near Seville boasts 2,650 heliostats which aim solar radiation at the tower’s receiver system. Because Gemasolar is a first-of-its-kind; challenges have been present at every project stage. SENER also required heat exchanger tubing to operate effectively within the steam generator units. We also provided over 300m of 19mm OD heat exchanger tubes manufactured from the same nickel-chromium alloy, but with a thicker wall to withstand the high pressures present within the steam generators. After a routine annual maintenance stop at the beginning of 2012, the plant achieved continuous 24-hour production for 12 straight days in winter, successfully delivering the projected energy supply to the grid. There is still a lot to learn about the operation of a plant as unique as Gemasolar and to SENER it represents a starting point for the cost reduction strategy in the thermosolar energy sector.
This is a global industry that will continue to grow and Torresol Energy has plans to develop more of these large scale plants throughout the world. SENER was selected as a winner in the awards presented by the FIDIC, the International Federation of Consulting Engineers, for its Gemasolar project. In 2013, SENER  was awarded The European Energy Awards as Engineering Company of the Year. SENER has a wide experience in the development of process and power generating plants, especially in combined cycle, cogeneration, thermosolar, nuclear energy, liquid natural gas regasification, biofuels, refinery units, chemicals, petrochemicals and plastics plants, as well as in transportation, storage and distribution systems for solid, liquid, and gaseous fuels. SENER has earned an outstanding reputation in generation and efficient use of energy as well as in chemical and industrial processes. In case we are not able to provide you with a quote for the required specifications, we can forward your enquiry to our sister company Superior Tube in the US for a competitive quotation. Imagine how hot it would be if an entire field’s worth of sunlight were focused onto one tiny point. The beam created by all of these reflecting mirrors is used to heat a liquid to an extremely hot temperature—sometimes over 1000°F! Solar concentrating power is important because it produces energy without releasing harmful greenhouse gases into the atmosphere. In fact, all of the energy that the ocean, land, and air absorb from the Sun in just 1.5 hours could power the whole Earth for an entire year!
Many countries, including the United States, are beginning to adopt concentrating solar power. It is easily installed and is used in large scale solar thermal tower power plant applications. Tower heliostat is one of key parts for tower CSP station and it is a concentrating device composed of mirror surface (mirror), mirror mount ( support structure), tracking and transmission mechanism as well as control system.
These include the first photovoltaic system to convert sunlight to electricity with more than 20% efficiency in 1989; the new result doubles this performance. Another partner in the research was Spectrolab, a US-based company that provided some of the cells used in the project. Incoming sunlight in a solar power tower is reflected down to a silicon solar cell receiver. It will also be presented at the Australian PV Institute’s Asia-Pacific Solar Research Conference, which begins at UNSW today (Monday December 8). If you are talking about direct conversion technology and not still relying on thermal neutrons. Perhaps they decided they needed the economic stimulus that comes with a lower price, or perhaps it is that there is a set of oil rich countries that are somewhat pathological in their behaviour and that dropping the oil price is a great way of sending them a message that they can’t ignore, perhaps it is a bit of everything? A 12MW unit running for 1 hour would generate as much energy as is contained in a 10 kiloton bomb.
It isn’t always clean either, look at the horrendous mess in China near some of the solar cell producers, toxic waste silicone compounds dumped near villages so they can no longer grow food etc. One thing puzzles me – on the “PS10 Solar Power Plant in Spain” there is no provision to follow the trajectory of the sun during the day. Some heat generated would need to keep the balloons in the air, but then they could capture huge areas (out in the desert or area where blocking light from surrounding areas is not a problem).
In fact it will increase in countries that would rather convert coal to plastics and fuel rather than buy Arab and or Russian oil.
Because its central tower receiver and molten salt storage technology enables it to produce electricity for 15 hours without the sun (and even 24 hours in summer time), Gemasolar can continue to operate during the night or cloudy weather.


The service conditions of components required high quality and reliable products - which Fine Tubes has rigorously fulfilled.
During 2001-2005 the company worked on two groundbreaking solar power plant projects, Solar Tres and Andasol-1, which provided them with enormous research and development opportunities resulting in the creation of Gemasolar. Together with Abu Dhabi’s alternative energies company MASDAR, the company formed Torresol Energy in 2008 and Gemasolor started commercial production in 2011. The radiation heats molten salts that circulate inside the tower to temperatures of more than 500 °C. It is unique due to its innovative design and cutting edge equipment developed by SENER; notably the central tower and receiver, the solar field and the control system.
Once again quality and durability were imperative, the units work at very high pressure turning the turbines to generate electrical power for over 27,500 homes per year. Because we were able to exceed the standard definitions required for these component parts, SENER selected us to be the exclusive supplier of tubes for the manufacturing panels of the central receiver.
The results achieved in the first year of Gemasolar operation have broken all expectations. For the coming year, the plant is projected to continue the same upward production trend, producing a total for the year of over 110 GWh net, functioning for a total of 6,450 hours at full capacity. The company is confident that its future tower projects will be much more profitable and that in the coming years with the standardisation of the industry, concentrated solar power (CSP) can be competitive with traditional energy sources. New opportunities are being sought in the international market and the company is developing solar plants in India, the United States, the MENA region and South Africa. SENER received this award for innovative projects such as the Gemasolar solar thermal plant. Its services include all of the possible engineering and construction operations such as: feasibility and conceptual design studies, facility basic and detail engineering, procurement, work supervision, start-up, training of personnel, construction and construction management as well as EPC projects.
A tiny magnifying glass is able to focus just a little bit of the Sun’s light into a hot beam.
The mirrors are lined up in a north-south direction and they follow the Sun as it moves from east to west. These mirrors are all directed at one single point—a tall tower containing the liquid to be heated. It can track sun, concentrate and reflect solar energy, and produce high temperatures to power any turbine.
Usage of solar for generating electricity is a good initiative for doing our bit in saving the earth.There are many commercial solar companies that have come up with solar power installation techniques. I hope LM have hit the jackpot, it will ensure my children have a prosperous future and climate change by any cause will not matter because with that amount of energy you can grow food anywhere. This means, for the first time solar energy has become manageable, and capable of responding to large scale commercial demand.
Other remarkable aspects during the manufacturing process were meeting deadlines, and continuous information transfer, two points where the collaboration with Fine Tubes was crucial and essential for the successful development of the project." Santiago Arias, Technical Director of Operation and Maintenance, from Torresol Energy, and Peru Arribalzaga, Project Management of SENER.
These salts are used directly as the heat absorption fluid: they are pumped from the cold molten salt tank to the receiver at the top of the tower, where they are heated to extreme temperatures, after which they descend to the hot molten salt tank or directly to the heat exchanger where they generate steam.
We have produced over 15 km of high performance 25mm OD seamless tubing for the system, which holds the 565°C molten salt (nitric salt), housed in the 140 metre high Gemasolar tower.
Since then, its available production hours are increasing significantly and it is hitting all production goals. Several potential new plants are foreseen and SENER is already working with Fine Tubes on further collaborations - as the receiver of each new plant will use around 50km of tubes. Instead of focusing light at a single point, the light is directed along a pipe containing the liquid to be heated. Tower solar thermal mirror has a reflective quality of more than 90% to track and focus the sun with an accuracy of less than 3.5mrad, in six wind work. If you haven’t heard about that you have being listening to marketing guff and fairy tales.
Well actually facing away at between about 45 and 90 degrees as the light comes in, hits the bragg surface, reflects off as a rainbow, then is absorbed by the stack of junctions. Made from the corrosion-resistant nickel-chromium alloy, the tubing has superior resistance to very high temperatures and the extreme service conditions.
