Photovoltaic Solar Panels

ES-A Series Photovoltaic Solar Panels

The new ES-A and ES-B Series feature high quality String Ribbon™ solar panels made with the latest generation of Evergreen Solar's revolutionary wafer technology. No other solar panels combine exceptional performance and industry-leading environmental credentials with the ability to be installed on virtually any roof in almost any climate.

About Strong Ribbon™ Technology

Evergreen Solar's String Ribbon™ wafers originate from the natural science of “surface tension”. In simple terms the making of a String Ribbon wafer is just like the making of a soap bubble — the surface tension between the soapy bubble solution and the wand creates the bubble.

The only difference is that instead of the “ring” inside which a bubble forms, we use two parallel high-temperature filaments between which a thin film of silicon is formed. With our proprietary technique, two high-temperature filaments are pulled vertically through a silicon melt, and the molten silicon spans and solidifies between the filaments.

The process is continuous, silent and clean: long high-temperature filaments unwind from spools, run through the molten silicon and pull a long strip of silicon out of the melt. The wafer strip is harvested periodically and cut into smaller pieces for further processing into solar cells.
