Methodology to predict annual yield losses and gains caused by solar module design and materials under field exposure

Methodology to predict annual yield losses and gains caused by solar module design and materials under field exposure

• Optimizing module design for a maximum annual performance. • Detailed gain and loss analysis from cell under STC to module in real environment. • Understanding the impact of module material on the annual module yield. • Impact of angular light, temperatures, lower irradiances on module performance. • Impact of weather condition (ambient temperature, wind speed) on module performance.

Methodology for Generating High Time Resolution Typical Meteorological Year Data for Accurate Photovoltaic Energy Yield Modelling

Methodology for Generating High Time Resolution Typical Meteorological Year Data for Accurate Photovoltaic Energy Yield Modelling

Accurate energy yield prediction is of utmost importance for commercial scale photovoltaic systems. One key parameter crucial to the prediction accuracy is the quality of solar radiation data. Most energy yield prediction models rely on Typical Meteorological Year data with maximum temporal resolution of one hour. In this work we develop a methodology to generate Typical Meteorological Year data with much higher time resolution using gap filling methods that aim to maintain high-quality solar radiation data for photovoltaic yield modelling.

Analysis of Hotspots in Half Cell Modules Undetected by Current Test Standards

Analysis of Hotspots in Half Cell Modules Undetected by Current Test Standards

Hotspots are a major source of failure for photovoltaic modules in the field. The current standard for module testing IEC 61215-2 can leave critical hotspots undetected in half-cut solar cell modules.

2-D Hot Spot Temperature Simulation for PV Modules

2-D Hot Spot Temperature Simulation for PV Modules

A two‐step method to simulate the spatially resolved temperature of a partially shaded cell in a crystalline silicon photovoltaic (PV) module is presented and tested.

Hotspot Modelling of Half-Cell and Full-Cell Module

Hotspot Modelling of Half-Cell and Full-Cell Module

The impact of partial shading on cell operating current, voltage, and temperature is simulated, for a half-cell module with series-parallel-series connections and for the conventional full-cell module.
