The visual effect is obviously stunning. And while the fabrication may be somewhat more complicated than flattening the lens, leaving the sphere whole has two benefits that seem to offset this. <\/p>\n<p><img decoding=\"async\" src=\"http:\/\/landartgenerator.org\/blagi\/wp-content\/uploads\/2012\/08\/rawlemon4.jpg\" alt=\"\" title=\"rawlemon4\" width=\"500\" height=\"295\" class=\"alignleft size-full wp-image-2348\" \/><\/p>\n<p>First, every section cut that is made in the face of a lens to flatten it into its Fresnel shape creates inefficiencies in the optics when compared to the original lens. Rawlemon&#8217;s sphere maintains 100% optic purity which leads to greater efficiency and more KW capacity per unit of surface area. Second, by leaving the lens as a complete orb, the tracking can take place behind the lens. The benefit of this is that instead of a system where an <a href=\"http:\/\/www.soitec.com\/en\/products-and-services\/solar-cpv\/power-plants\/\" target=\"_blank\">large wall<\/a> of CPV modules has to be moved to track the sun, each multijunction cell can rotate like a little satellite behind its spherical lens. This design leaves the &#8220;wall&#8221; of modules free to stay in its static position, either as a vertical building facade or at any angle.<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/landartgenerator.org\/blagi\/wp-content\/uploads\/2012\/08\/rawlemon3.jpg\" alt=\"\" title=\"rawlemon3\" width=\"500\" height=\"341\" class=\"alignleft size-full wp-image-2347\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We came across this spectacular application of concentrated solar power via designboom.
