The project aimed to design and develop an integrated system for real time monitoring of the available solar potential in Greece, to produce detailed solar energy maps and to predict solar energy in short term periods. The system is supported by an updated climatologic study for solar energy regarding the past 10 years. All developed products are web-based so that almost real time data can be provided to any stakeholder, while measurements are submitted to international databases. The final product aims to play significant role in the assessment of the energy performance of Solar Energy companies and the improvement of sustainable energy business in general, while it also aims to incorporate the Greek network of solar energy measurement stations into the World Radiation Data Centre (WRDC).
