This paper is proposing and analyzing an electric energy storage system fully integrated with a photovoltaic PV module. composed by a set of lithium-iron-phosphate (LiFePO4) flat batteries. which constitutes a generation-storage PV unit. The batteries were surface-mounted on the back side of the PV module. https://www.spidertattooz.com/The-GelBottle-Inc-Gel-Polish-Audrey-67oz-p17921/
