Exploratory evaluation of solar radiation and ambient temperature in twenty locations distributed in United Kingdom

Abstract

Solar radiation and ambient temperature is a foundation resource programs of large-scale deployment of solar energy technologies. This paper summarizes the analysis of a weather station network in United Kingdom. Whistle 3 years (January 2015-December 2017) of data from twenty weather stations distributed across the country. The data comprises of Global Horizontal Irradiance (GHI), Diffuse Horizontal Irradiance (DHI), Direct Normal Irradiance (DNI), ambient temperature, wind speed, and the humidity. Network design, implementation, and data quality assurance are described, in order to document the network extent and quality. From all observed datasets, it was found that Plymouth (located in southwest England) has the dominant GHI, and ambient temperature among all other 19 locations. The least GHI is observed for Aberdeen (located in northeast Scotland) estimated at 77.3 kWh/m 2. However, the least average ambient temperature is equal to 9.1 ºC, this data was detected from the weather station located in the capital of Scotland (Edinburgh). Although continued measurements are needed to understand the interannual resource variability, the current study provides significant guidance for preliminary technology selection, power plant modeling, and resource forecasting.

Performance Ratio and Degradation Rate Analysis of 10-Year Field Exposed Residential Photovoltaic Installations in the UK and Ireland

“…This result was due to the high degradation rates of these PV systems; their annual degradation rates were always higher than −1.0%/year. This result also confirmed that PV hot spotting, heavy snow, and hoarfrost affected the PR values of all PV systems installed in cold areas [30].…”

Caracterización de radiación solar directa y difusa en condiciones climáticas del Valle del Mantaro

“…En caso nuestro, el análisis se hizo a la radiación directa y difusa y no del global, sin embargo, podemos estimar con el intervalo del tiempo de radiación por día que es 8 horas y la suma de radiación difusa y directa, por tanto, la radiación global en promedio anual sería 6,804 kW h/m 2 x día, es decir, significativamente mayor que la radiación de la India. Sin embargo, existe países que tienen alta radiación, tal como se muestra en el estudio Evaluación exploratoria de la radiación solar y la temperatura ambiente en veinte lugares distribuidos en el Reino Unido, en el que la radiación máxima alcanza 103 kW h/m 2 y como mínimo 73,6 kW h/m 2 , esto realmente es superior a la nuestra (Dhimish & Mather, 2019).…”

“…El diseño y la evaluación del rendimiento del sistema solar fotovoltaico y térmico requiere el conocimiento de la radiación solar global (Manju & Sandeep, 2019). La radiación solar y la temperatura ambiente son los recursos básicos para el despliegue a gran escala de tecnologías de energía solar (Dhimish & Mather, 2019). La explotación de la energía solar en sistemas solares térmicos y fotovoltaicos requiere el análisis de los datos de radiación solar y los modelos utilizados para evaluar el rendimiento de los sistemas (Jamil & Akhtar, 2017).…”

Insights on the Degradation and Performance of 3000 Photovoltaic Installations of Various Technologies Across the United Kingdom

“…The normalized energy profile reveals a power peak during summertime, and the lowest normalized energy is observed during four months from November, until February. This is expected, as the actual solar irradiance is naturally low in the UK during the winter season [29]. In contrast, the normalized energy of the aggregation process would be expected to diverge dependent on the actual weighted temperature and the solar irradiance at the examined PV installation.…”
