From sand to module
 |
The main resource used for photovoltaic modulesis silicon, which is obtained from sand and is thesecond most abundant elementon earthavailable almost unlimited. |
 |
 |
From the silica, silicon isobtained in pure form. We focus on highest quality possible, because onlywith the purestsiliconhigh qualityproductscan be suppled to market. |

The high-puritysiliconis melted atabout 1400degrees celsius,formed into blocks andfrozen.Then thesiliconblocks are cutby wiresaw technologyand result inextremely thin silicon discs,calledwafers. |
 |
 |
The wafers aresoldered automatically and processed into solar cells.They are the basic elements ofsolar modulesandhave all the necessaryfeaturesto produceelectricity from sunlight. |  |
 |
In our manufacturingthe solar cells areassembled intomodules.They areframedandglazed and the producedelectricity is gathered by a junction box(collector). Image caption: 1 Aluminium frame, 2 Seal, 3 Glass, 4 Encapsulating EVA, 5 Crystalline cell, 6 Tedlar sheet |

The so produced electricity is direct current (DC) but for residential use or grid connection it is converted alternating current (AC) using an inverter. |
