 From sand to module


sand 50x200 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.

cell 300x200 The wafers aresoldered automatically and processed into solar cells.They are the basic elements ofsolar modulesandhave all the necessaryfeaturesto produceelectricity from sunlight. cell 50x200

In our manufacturingthe solar cells areassembled intomodules.They areframedandglazed and the producedelectricity is gathered by a junction box(collector).

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