The increasing interest in IoT devices poses significant challenges in battery waste, not to mention the effort needed to replace the batteries in remote applications. In the LoLiPoP-IoT project, we address these issues by developing energy-efficient IoT platforms that extend the device's battery life through low-power design and energy harvesting. However, for a successful design, preliminary measurements and simulations need to be done to demonstrate the feasibility of the utilized technologies and their dimensioning. This paper presents a method of collecting data and creating a novel portable simulation model implemented in a Microsoft Excel spreadsheet. During the data collection phase, we plot detailed energy consumption and income of our device (i.e., asset tracking tag). PC1D simulations of a crystalline-silicon photo-voltaic panel and the device model were utilized to collect data for the final (i.e., composed) model. Our model allows real-time adjustments of key parameters, such as ambient light intensity, battery capacity, and photo-voltaic panel sizing. Our goal is to deliver a solution that allows our partner to conduct basic experiments on their own computers with a user-friendly interface for parameter selection and result visualization. Our results indicate that for one application area, a 25cm2 photo-voltaic panel is needed, while for the other, a 23cm2 panel is enough.
