Analysis of spectral irradiance distribution for PV applications at high latitude
Paudyal, Basant Raj; Imenes, Anne Gerd (Chapter, 2020)The spectral distribution of global tilted irradiance measured in Grimstad, Norway, is analyzed in terms of the average photon energy (APE) blue fraction (BF) and useful fraction (UF). The results based on eight months of ... -
Analysis of spectral irradiance variation in northern Europe using average photon energy distributions
Paudyal, Basant Raj; Somasundaram, Sakthi Guhan; Louwen, Atse; Reinders, Angele H.M.E.; van Sark, Wilfried G.J.H.M.; Stellbogen, Dirk; Ulbrich, Carolin; Imenes, Anne Gerd (Peer reviewed; Journal article, 2024)One major factor affecting the energy yield of photovoltaic modules is the spectral distribution of incident solar radiation. As spectral irradiance data is scarce, this study provides further documentation of recorded ... -
Bandgap Optimization of Photovoltaic Tandem Cells Based on Spectra Collected over a Full Year
Strandberg, Rune; Imenes, Anne Gerd (Peer reviewed; Journal article, 2024)Spectral data collected every minute at the test station in Grimstad, Norway, are used to investigate the impact of spectral variation on tandem cells. The results are displayed as efficiency maps which are compared to ... -
Energy measurements at Skarpnes zero energy homes in Southern Norway: Do the loads match up with the on-site energy production?
Sørensen, Åse Lekang; Imenes, Anne Gerd; Grynning, Steinar; Dokka, Tor Helge (Journal article; Peer reviewed, 2017)Five houses are designed as zero-energy homes in Skarpnes, Norway. The energy goal is to achieve net zero-energy balance on an annual basis. The houses have heat pumps and solar cells (PV). Energy use and delivered energy ... -
Investigation of temperature coefficients of PV modules through field measured data
Paudyal, Basant Raj; Imenes, Anne Gerd (Peer reviewed; Journal article, 2021)Varying broadband irradiance and temperature are generally known as the major factors influencing the performance of PV modules, but studies have also shown the substantial impact of spectral variations. In this work, a ... -
Moisture ingress in photovoltaic modules: A review
Segbefia, Oscar Kwame; Imenes, Anne Gerd; Sætre, Tor Oskar (Peer reviewed; Journal article, 2021)Moisture ingress in photovoltaic (PV) modules is the core of most degradation mechanisms that lead to PV module power degradation. Moisture in EVA encapsulant can lead to metal grids corrosion, delamination and discolouration ... -
Performance Analysis of PV Power Plants Across Norway
Kristiansen, Martin Krebs (Master thesis, 2023)This thesis examines hourly aggregated data from 501 photovoltaic (PV) installations, builds a better knowledge foundation about the geographical performance of PV systems in Norway, and provides a groundwork for how PV ... -
Performance assessment of field deployed multi-crystalline PV modules in Nordic conditions
Paudyal, Basant Raj; Imenes, Anne Gerd (Journal article; Peer reviewed, 2019) -
Preserving the Past, Powering the Future: Energy Efficiency and Renewables in Norway's Wooden Churches
Tømte, Thomas (Master thesis, 2023)This master’s thesis explores the potential for energy efficiency in three wooden churches built in the 19th century in the southern part of Norway. Specifically, the thesis focuses on the three churches Eide, Landvik, and ... -
Review of Guidelines for PV Systems Performance and Degradations Monitoring
Paudyal, Basant Raj; Imenes, Anne Gerd; Sætre, Tor Oskar (Journal article, 2018)The recent growth in the PV system deployment and the higher scale of their production make it necessary to pay more attention towards the performance of those systems. System monitoring will provide the status of the ... -
Uniqueness verification of blue fraction as a parameter of spectral irradiance quantification
Paudyal, Basant Raj; Imenes, Anne Gerd (Chapter, 2021)The spectral distribution of global irradiance is measured in the optimal tilt (45° south) plane of array for the calender year 2020 in Grimstad, Norway. In this work the spectral distribution is quantified in terms of the ...
