Currently, a vast amount of research institutions and organizations are focusing on ways to improve the operation, reliability and consequently the output of PV systems. An important aspect yet to be targeted remains the procedural and standardized approach to calculate accurately the factors behind the various performance loss mechanisms, while also detecting and diagnosing potential failures at early stages or before occurrence. Identification of degradation and failure modes at preliminary stages is important as these mechanisms directly influence the performance, lifetime and reliability of PV technology.
It is with this background that project IPERMON has been initiated in order to primarily monitor and assess PV system performance, through the formulation of a procedural protocol (starting from sensor installation, data acquisition and filtering, to time series analysis) for the development of algorithms to detect performance losses, failures and degradation mechanisms at an early stage, which will significantly improve and ensure quality of operation of grid-connected PV systems in order to fulfil and guarantee owner/investor expectations.
The project started in April 2016, and is scheduled to run for 36 months. The IPERMON project is co-financed by the European Regional Development Fund and the Republic of Cyprus through the Cyprus Research Promotion Foundation (DESMI 2009-2010) with grant number KOINA/SOLAR-ERA.NET/1214/08.
