Rapid, terawatt-scale deployment of photovoltaic (PV) modules is required to decarbonize the energy sector. Despite efficiency and manufacturing improvements, material demand will increase, eventually resulting in waste as deployed reach end life. Circular choices for decommissioned could reduce offset virgin materials. We present PV ICE, an open-source python framework using modern reliability data, which tracks module flows throughout life cycles. provide dynamic baselines capturing...
Among the many ambitious decarbonization goals globally, US intends grid by 2035, requiring 1 TW of installed photovoltaics (PV), up from ~110 GW in 2021. This unprecedented global scale-up will stress existing PV supply chains with increased material and energy demands. By 2050, 1.75 cumulatively demands 97 million metric tonnes virgin creates 8 life cycle waste. analysis leverages Circular Economy tool (PV ICE) to evaluate two circular economy approaches, lifetime extension closed-loop...
Abstract Solar photovoltaics (PV) are the fastest growing renewable energy technologies for clean, cheap, and sustainable electricity generation. To prepare rapid scale‐up, PV industry needs to project material requirements build out all aspects of supply chain appropriately plan handle large volumes module waste. Impacts deploying different circularity strategies reduce waste conserve primary resources need be quantified inform management. Here, we introduce photovoltaic dynamic flow...
Abstract Artificial ground reflectors improve bifacial energy yield by increasing both front and rear‐incident irradiance. Studies have demonstrated an increase in due to the addition of artificial reflectors; however, they not addressed effect varying reflector dimensions placement on system performance impact these parameters reflectors' financial viability. We studied high albedo (70% reflective) single‐axis‐tracked photovoltaic systems through ray‐trace modeling field measurements. In...
Global decarbonization requires an unprecedented scale-up of photovoltaic (PV) manufacturing and deployment. The material demand eventual end life management associated with multi-TW scale deployment poses many challenges. Circular Economy (CE) it's R-Actions (Reduce, Reuse, Recycle) have been proposed to mitigate sourcing concerns. However, CE metrics typically focus on a single product only consider mass, excluding energy flows. This work leverages the PV in (PV ICE) tool quantify...
Abstract The Photovoltaic (PV) Performance Modeling Collaborative (PVPMC) organized a blind PV performance modeling intercomparison to allow modelers blindly test their models and ability against real system data. Measured weather irradiance data were provided along with detailed descriptions of systems from two locations (Albuquerque, New Mexico, USA, Roskilde, Denmark). Participants asked simulate the plane‐of‐array irradiance, module temperature, DC power output six submit results Sandia...
Abstract Achieving the energy transition sustainably requires addressing how new technologies may impact justice in system. The Justice Underpinning Science and Technology Research (JUST-R) metrics framework was recently proposed to aid researchers considering early-stage research on technologies; however, case study evaluations of revealed a desire from see specialized particular fields study. Here, we refine JUST-R enhance its applicability photovoltaic (PV) materials research. Metrics are...
Three standards for photovoltaic (PV) performance and capacity testing are evaluated bifacial PV system reporting: ratio, ASTM E2848, a new draft of IEC 61724-2. In this context, challenges recommendations rear irradiance instrumentation described three types sensors—horizontal albedometer, backward-facing reference cells (or pyranometer), module. A year operating field data single-axis tracked monofacial systems was collected, including periods high surface albedo due to snow ground cover....
Transitioning from fossil-fuel power generation to renewable energy and storage in remote locations has the potential reduce both carbon emissions cost. We present a techno-economic analysis for implementation of hybrid system at South Pole Antarctica, which currently hosts several high-energy physics experiments with nontrivial needs. A tailored model use solar photovoltaics, wind turbine generators, lithium-ion storage, long-duration this site is explored different combinations without...
As sustainable deployment and end-of-life management become a hot topic to timely address in the PV community, dynamic comparative evaluation of benefits circular pathways such as reuse, remanufacturing, recycling has not been performed holistically beyond material flows or LCA analysis. Energy are critical for evaluating energy generation technologies. Previously they have used compare renewables fossil then between This paper quantifies evaluate PV. The tracking manufacturing, generation,...
When photovoltaic (PV) modules are installed on rooftops, the module temperature depends primarily geographic location and mounting configuration. If structure does not provide sufficient airflow in a hot environment, 98th percentile will exceed 70°C, which according to IEC TS 63126, requires higher levels of thermal stability testing. However, there is no clear way determine level needed for particular system design. In this work, we identify relationship between standoff rooftop propose...
