This is a scalable technology, however, the larger production appears to be the most efficient use of the related technology.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"><b>Concentrating Solar Power (CSP) Basics<\/b><\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> Many power plants today use fossil fuels as a heat source to boil water. The steam from the boiling water spins a large turbine, which drives a generator to produce electricity. However, a new generation of power plants with concentrating solar power systems uses the sun as a heat source. The three main types of concentrating solar power systems are: linear concentrator, dish\/engine, and power tower systems.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> Linear concentrator systems collect the sun&#8217;s energy using long rectangular, curved (U-shaped) mirrors. The mirrors are tilted toward the sun, focusing sunlight on tubes (or receivers) that run the length of the mirrors. The reflected sunlight heats a fluid flowing through the tubes. The hot fluid then is used to boil water in a conventional steam-turbine generator to produce electricity. There are two major types of linear concentrator systems: parabolic trough systems, where receiver tubes are positioned along the focal line of each parabolic mirror; and linear Fresnel reflector systems, where one receiver tube is positioned above several mirrors to allow the mirrors greater mobility in tracking the sun.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> A dish\/engine system uses a mirrored dish similar to a very large satellite dish, although to minimize costs, the mirrored dish is usually composed of many smaller flat mirrors formed into a dish shape. The dish-shaped surface directs and concentrates sunlight onto a thermal receiver, which absorbs and collects the heat and transfers it to the engine generator. The most common type of heat engine used today in dish\/engine systems is the Stirling engine. This system uses the fluid heated by the receiver to move pistons and create mechanical power. The mechanical power is then used to run a generator or alternator to produce electricity.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> A power tower system uses a large field of flat, sun-tracking mirrors known as heliostats to focus and concentrate sunlight onto a receiver on the top of a tower. A heat-transfer fluid heated in the receiver is used to generate steam, which, in turn, is used in a conventional turbine generator to produce electricity. Some power towers use water\/steam as the heat-transfer fluid. Other advanced designs are experimenting with molten nitrate salt because of its superior heat-transfer and energy-storage capabilities. The energy-storage capability, or thermal storage, allows the system to continue to dispatch electricity during cloudy weather or at night.<\/span><\/span><\/p>\n<table border=\"0\" width=\"9\" cellspacing=\"0\" cellpadding=\"2\">\n<colgroup>\n<col width=\"5\" \/> <\/colgroup>\n<tbody>\n<tr>\n<td width=\"5\"><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><img decoding=\"async\" src=\"https:\/\/encrypted-tbn3.gstatic.com\/images?q=tbn:ANd9GcQ6JMPrn9IG3Gvlc73hHv_YmZqq2OPCMD_MqOELomMFHPuFQzN9\" width=\"252\" height=\"177\" name=\"J4QjqqKYoZUGIM:\" align=\"BOTTOM\" border=\"0\" \/><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> There\u2019s more than one way to make good use of the Stirling cycle. Just ask the engineers at Infinia, Kennewick, Wash. They use it in both their PowerDish, a device already on the market that turns sunshine into electricity, and StAC, an innovative air conditioner that has earned development grants from the government. Both exemplify energy efficiency and sustainability.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><strong><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\">PowerDish<\/span><\/span><\/strong><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-size: medium;\"><span style=\"font-family: Arial,sans-serif;\"> In the PowerDish, heat from the Sun drives a free-piston Stirling power generator, an external combustion engine.

Sunlight gets concentrated in an 800-to-1 ratio, which would raise the temperature at the heat-resistant nickel-alloy concentrator to 2,000\u00b0C if the Stirling generator didn\u2019t extract heat from it and keep it at about 650\u00b0C, says Tim Talda, Infinia\u2019s director for system electronics and controls.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> You can learn more about this technology at: <a href=\"http:\/\/machinedesign.com\/energy\/infinia-uses-stirling-cycle-solar-power-and-air-conditioning\">http:\/\/machinedesign.com\/energy\/infinia-uses-stirling-cycle-solar-power-and-air-conditioning<\/a>.

CSP plants generate electric power by using mirrors to concentrate (focus) the sun&#8217;s energy and convert it into high-temperature heat. That heat is then channeled through a conventional generator. The plants consist of two parts: one that collects solar energy and converts it to heat, and another that converts the heat energy to electricity. A brief video showing how concentrating solar power works (using a parabolic trough system as an example) is available from the Department of Energy Solar Energy Technologies Web site.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> Within the United States, CSP plants have been operating reliably for more than 15 years. All CSP technological approaches require large areas for solar radiation collection when used to produce electricity at commercial scale.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> CSP technology utilizes three alternative technological approaches: trough systems, power tower systems, and dish\/engine systems.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\">Trough Systems<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> Trough systems use large, U-shaped (parabolic) reflectors (focusing mirrors) that have oil-filled pipes running along their center, or focal point, as shown in Figure 1. The mirrored reflectors are tilted toward the sun, and focus sunlight on the pipes to heat the oil inside to as much as 750\u00b0F. The hot oil is then used to boil water, which makes steam to run conventional steam turbines and generators.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> These are utility scale solar power systems. They require land, permitting, grid management, employees, taxes, insurance and all the usual conditions for a mid-level business structure. There are many of these projects underway and ready for new investment capital and expansion and it makes perfect sense to join with existing businesses in this area.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> Another very promising species of this concept is the use of concentrated solar with photovoltaic power generation. The global market for concentrated photovoltaic (CPV) systems is on the verge of explosive growth, with worldwide installations set to skyrocket 750% between 2013 and 2020, according to a report published on Tuesday by market research group IHS.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> IHS is a global information company with world-class experts in the pivotal areas shaping today&#8217;s business landscape: energy, economics, geopolitical risk, sustainability and supply chain management. It employs more than 8,000 people in more than 31 countries around the world.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> In the new IHS Report, Concentrated PV (CPV) Report \u2013 2013, IHS predicts CPV installations will rise to 1,362 MW in 2020, up from 160 MW in 2013. Indeed, installations are expected to expand at double-digit percentages every year through 2020.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> CPV technology employs lenses or mirrors to focus sunlight onto solar cells. While this allows for more efficient PV energy generation, the use of additional optics for focusing sunlight has also driven up the cost of CPV compared to conventional PV installations, limiting the acceptance of concentrated solar solutions.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><a name=\"irc_mi2\"><\/a><img fetchpriority=\"high\" decoding=\"async\" src=\"\/\/www.greenrhinoenergy.com\/solar\/technologies\/images\/Concentrating%20PV-06.jpg\" width=\"403\" height=\"292\" name=\"graphics14\" align=\"BOTTOM\" border=\"0\" vspace=\"25\" \/><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> The situation is changing rapidly, however, as advancements in CPV technology are reducing costs.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> &#8220;What is happening in today\u2019s CPV market is very similar to that of the overall PV space in 2007, beset by high costs and an uncertain outlook,&#8221; said Karl Melkonyan, photovoltaic analyst at IHS. &#8220;However, the CPV market in 2013 is on the verge of a breakthrough in growth. Costs for CPV have dropped dramatically during 2013 and are expected to continue to fall in the coming years. Furthermore, when viewed from the perspective of lifetime cost, CPV becomes more competitive with conventional PV in large ground-mount systems in some regions.&#8221;<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> Prices for CPV are retreating as manufacturing processes progress down the learning curve.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> Average installed pricing for high-concentration PV (HCPV) systems are estimated to have decreased to $2.62 per watt in 2013, down 25.8% from $3.54 per watt in 2012. Rising volumes and improved system efficiencies are driving the decline, according to the report, which adds that prices will slide further at an annual compound rate of 15% from 2012 to 2017, falling to $1.59 by the end of 2017.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\">Taking lifetime costs into account<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> In the conventional PV market, cost analysis predominantly focuses on the module price-per-watt and the total installed cost-per-watt, IHS points out. When comparing the installed cost-per-watt of conventional PV to CPV, the cost of conventional PV is significantly lower.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> &#8220;This is mainly due to the higher panel cost of CPV, given that CPV suppliers have yet to achieve the economies of scale, as well as a better balance of system and installation cost, because of the required tracker system,&#8221; IHS says.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> &#8220;To be sure, conventional PV has a lower upfront cost and appears to be a more attractive option based on upfront system costs. However, this does not take into account the overall cost of the system over its lifetime, nor does it consider the energy yield of the system.&#8221;<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> Instead, the report adds, it is important to compare the levelized cost of electricity (LCOE). The LCOE estimates the cost of generating electricity at the point of connection, dividing the total lifetime system costs by the total energy produced over the system\u2019s lifetime.<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> &#8220;Such a calculation is also necessary in order to compare the competitiveness of PV and CPV with that of conventional power generation.&#8221;<\/span><\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"> Using the LCOE, IHS predicts that system costs for HCPV will remain low enough to compete with conventional PV for large commercial, ground-mount systems in target regions. These are the areas with hot, dry climates and high daily irradiation at more than 6 kilowatt-hours per square meter of direct normal irradiation.<\/span><\/span><\/p>\n<h2 class=\"western\" align=\"JUSTIFY\"><a name=\"post-71\"><\/a> <span style=\"font-family: Arial,sans-serif;\"><span style=\"font-size: medium;\"><a href=\"http:\/\/manfred.amoureux.free.fr\/?p=71\">Power generation with solar tracking systems : CSP vs CPV vs Flat PV<\/a><\/span><\/span><\/h2>\n<p><span style=\"font-family: Arial,sans-serif;\">Manfred Armoureux Blog <\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"> The following is a comparison of CPV (concentrated photovoltaic) to CSP (concentrated solar power), more properly called concentrated thermo-electrical solar power to flat PV with solar tracking.<\/span><\/p>\n<p align=\"JUSTIFY\">\n<p align=\"JUSTIFY\">\n<p align=\"JUSTIFY\">\n<p align=\"JUSTIFY\">\n<p><span style=\"font-family: Arial,sans-serif;\"> CSP (concentrated solar power), more properly called concentrated thermo-electrical solar power<br \/>\n<img loading=\"lazy\" decoding=\"async\" src=\"\/\/manfred.amoureux.free.fr\/myUploads\/images\/images_solar_trackers\/csp.jpg\" width=\"301\" height=\"364\" name=\"graphics16\" align=\"BOTTOM\" border=\"0\" \/><img loading=\"lazy\" decoding=\"async\" src=\"\/\/manfred.amoureux.free.fr\/myUploads\/images\/images_solar_trackers\/solfocus_cpv_panel.jpg\" width=\"461\" height=\"276\" name=\"graphics15\" border=\"0\" \/> <\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-family: Arial,sans-serif;\">and flat PV panels with solar tracking<br \/>\n<img loading=\"lazy\" decoding=\"async\" src=\"\/\/manfred.amoureux.free.fr\/myUploads\/images\/images_solar_trackers\/pv_tracker3.jpg\" width=\"230\" height=\"149\" name=\"graphics17\" align=\"BOTTOM\" border=\"0\" \/> <\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\"> First, I should make clear for you that each one of those categories actually encompasses different sub-technologies. Solar tracking may be along one or two-axis. In particular, the CSP technologies show a great deal of variety between Fresnel, parabolic trough, parabolas and central receivers (there is plenty of literature available around there). CPV systems are usually not as well known but there is also very different systems : inflatable parabolas (<a href=\"http:\/\/www.coolearthsolar.com\/\">Cool Earth Solar<\/a>), Fresnel lenses (<a href=\"http:\/\/www.concentrix-solar.de\/\">Concentrix solar<\/a>), parabolic trough (<a href=\"http:\/\/www.exosun.fr\/\">Exosun<\/a>), panels of small parabolas (<a href=\"http:\/\/www.solfocus.com\/\">Solfocus<\/a>) and I am probably missing many other companies.<\/span><\/p>\n<p><span style=\"font-family: Arial,sans-serif;\"> Notwithstanding these differences, I chose to distinguish only the 3 categories\u00a0 mentioned above.<\/span><\/p>\n<p><strong><span style=\"font-family: Arial,sans-serif;\">Flat PV vs CPV<\/span><\/strong><\/p>\n<p><span style=\"font-family: Arial,sans-serif;\">We start with the easiest comparison.<\/span><\/p>\n<p><span style=\"font-family: Arial,sans-serif;\">Cons of CPV compared to Flat PV:<\/span><\/p>\n<ul>\n<li><span style=\"font-family: Arial,sans-serif;\">you only capture the DNI (direct normal irradiation) <\/span><\/li>\n<\/ul>\n<p><span style=\"font-family: Arial,sans-serif;\">Pros :<\/span><\/p>\n<ul>\n<li><span style=\"font-family: Arial,sans-serif;\">Price per peak watt, given that your concentrating systems costs less per unit of surface than the PV cells. <\/span><\/li>\n<li><span style=\"font-family: Arial,sans-serif;\">If your do cogeneration of heat using the (absolutely required) residual heat of cooling system, it is much easier to achieve significant temperatures (i.e. 60\u00baC) <\/span><\/li>\n<\/ul>\n<p><span style=\"font-family: Arial,sans-serif;\">So choosing CPV instead of flat PV can be summarized in two short questions :<\/span><\/p>\n<ul>\n<li>\u201c<em><span style=\"font-family: Arial,sans-serif;\">How much radiation do I loose because of diffuse radiation and how much cheaper per unit of surface is my CPV compared to flat PV<\/span><\/em><span style=\"font-family: Arial,sans-serif;\"> ?\u201d <\/span><\/li>\n<li><em>\u201c<span style=\"font-family: Arial,sans-serif;\">Could I use most of the residual heat ?

However, that engineers enjoy working on them is not what will make them successful on the market.<\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\">The main advantage of CSP compared to CSP is its capacity to produce also during night time (using thermal storage). Unfortunately, as far as I know, there is no country giving any special incentive for this. Thus, to the investors, it is irrelevant.<\/span><\/p>\n<p align=\"JUSTIFY\"><span style=\"font-family: Arial,sans-serif;\">The other advantage is that, at the present time, big CSP power plants are able to produce electricity at a cheaper cost than CPV.
