The JUICE Photovoltaic Assembly - from prequalification coupons to full-scale qualification model

In the frame of the JUICE (JUpiter ICy moon Explorer) mission, Leonardo Spa has been selected as PVA supplier of the Solar Array module. Due to the demanding environmental and general requirements, it was necessary to develop specific technological solutions to fulfill the low temperature, low sun intensity and very high radiation levels linked to the Jovian specific environment. The paper illustrates this development process, successfully verified with engineering coupons and then applied to full-scale qualification model, which test campaign is currently ongoing.
