The new online monitoring system SPYCE provides for PV system operators, inverter manufacturers and installers the internet portal www.spyce.de with irradiance data from satellite images, automated failure detection and alarms via email. The analysis of the SPYCE service shows a very high reliability of the data logger PEPPER, easy and fast installation and self-explanatory handling. The measurement data, automatically created reference energy yields and irradiance data from satellites are easy accessible in a protected area of the internet portal, as well as all results of the performance analysis. Failure detection is very fast and effective for monitored system units up to 10 kW. If several inverters of the same plant are monitored separately, an automated comparison of the inverter takes place, which enhances the efficiency of the failure detection and allows to monitor units up to 100 kW. False alarms are very seldom, as temperature and irradiance data is included in the analysis. SPYCE is available for grid connected PV systems in Europe and northern Africa. It is planned to offer SPYCE also in the USA and to implement string monitoring and monitoring of solar thermal plants.
