Abstract This report documents the demonstration of a self-adhering, thin-film photovoltaic (PV) technology applied to a new aluminum-zinc coated standing-seam metal roof (SSMR) with a high-performance coating. The demonstration took place at Kilauea Military Camp (KMC), HI, which has a uniquely corrosive environment due to the periodic presence of volcanic gases. It also has high electric utility costs and limited grid capacity. The corrosion performance of the roof and PV solar array was evaluated by periodic visual examination, onsite atmospheric coupon testing, and accelerated weathering laboratory tests of material coupons. Sensors were also installed at the interface between the PV membrane and roofing material, mounted in outdoor exposure at the site, to record any developing signs of corrosion. Af-ter a year in service, the PV appliqu modules were found to have no deleterious effect on the new SSMR, and the PV system performed as expected. However, due to the high first-costs related to procuring the thin-film PV components, the 30 year return on investment (ROI) ratio was only 0.19. Although the system is not economical enough to warrant Army-wide implementation, it may be specified in individual cases where energy sustainability is a higher priority than ROI.
