QUANTIFYING ENVIRONMENTAL EFFECTS FOR DIFFERENT DEVICE TECHNOLOGIES BASED ON PROPOSED ENERGYY RATING STANDARD

摘要

The most common parameter for comparison of photovoltaic (PV) modules is the output power at StandardTest Conditions (STC), which is a static set of test conditions which is reproducible under laboratory conditions but notnecessarily a good indicator of operating performance in the field. Profitability of PV-systems has become moreimportant and consequently the energy production or energy rating of modules. Therefore an easy to use energycomparator is required for industry, installers and customers. A method for the determination of module energy wasproposed in the draft standard IEC 61853, which currently is under discussion. This paper investigates the importance ofthe different measurements suggested in the original draft on the absolute energy yield for three module technologies,thus providing a sensitivity analysis of the expected modelling accuracy.
