Performance characterisation of photovoltaic modules

Influences on the energy delivery of thin film photovoltaic modules

“…Short term measurement sub-sets tend to produce negative temperature coefficients. The difference is that long term measurements are affected by seasonal spectral changes and thus groups utilising spectral information for correction of even long term measurements tend to still report negative temperature coefficients [46,47].…”

Thermal Monitoring of Photovoltaic module using Optical Fiber Sensors

“…In actual operating conditions some experiments also use this method, however in real world applications, which is subject to the incidence of winds, the thermal gradient generated by air movement can reveal significant uncertainty in the determination of the mean panel temperature, since the temperature is measured in a single point [25].…”

Accuracy of Energy Yield Prediction of Photovoltaic Modules

“…The Kipp & Zonen CM 11 pyranometer [17], an older but commonly used sensor, is utilised in the analysis as a case study. Previous irradiance uncertainty measurement studies only used the given uncertainty values in the equipment manufacturers manual [19][20][21][22][23][24][25][26][27]. A robust model is established that can analyse the irradiance measurement uncertainty and is applicable to any location.…”

[19][20][21][22][23][24][25][26][27] A robust model is established that can analyse the irradiance measurement uncertainty and is applicable to any location. The irradiance uncertainty components of the CM 11 sensor are categorised into two groups:…”
