New junction box design uses cost-cutting dielectric tough gel to substantially improve durability and performance. When Evergreen Solar, an innovative manufacturer of photovoltaic (PV) modules using patented String RibbonTM technology, began looking for ways to reduce module costs, redesigning the junction box became a potential solution. While redesigning a junction box may not be the first thing that comes to mind, it can actually deliver substantial benefits, as the cost of this critical reliability component is significant—and its durability and performance vital to customer satisfaction. Evergreen Solar had traditionally offered modules with large, general-purpose junction boxes well suited to the off-grid market. But as the on-grid market grew dominant, the company began to evaluate
