Global Horizontal Irradiance is the most commonly component of solar radiation to be measured. However, when projecting and installing solar energy systems, those are not installed horizontally but at a certain angle to optimize solar radiation interception. With this in mind, the present work is based on the solar radiation data measured by IPMA's-Portuguese Institute for Sea and Atmosphere network, consisting in 89 measuring stations across the country. With basis on the assessment of Global Horizontal Irradiation availability performed in previous publications, a known methodology was applied in order to estimate the Global Tilted Irradiation for each valid location of the network. Once the Global Tilted Irradiation is estimated for a surface tilted with an angle equal to the local latitude angle, an estimation of the potential solar photovoltaic energy production was performed.
