Identifying the Relative Benefit of Single-Axis Solar Panels with Respect to Energy Gains and Energy Costs
Year: 2026
Type: article
Abstract: This study examines whether the extra solar energy collected by a moving photovoltaic panel is greater than the energy needed to operate its tracking motor at the residential level in order to give homeowners a clearer basis for judging whether a solar-tracking system offers an advantage over a conventional fixed-panel installation.. Using hourly solar radiation data from the 2023 PVGIS-ERA5 dataset, we compabed the energy collected by fixed panels and single-axis tracking panels across North America. The tracker's energy use was estimated from JKONG Motor specifications, including voltage, current, torque, and efficiency, together with an assumed tracking schedule. We then subtracted motor energy consumption from the additional solar energy gained through tracking to calculate the system's net energy benefit, while keeping in mind the limits of modeled data.
