[Espejot]

What is SAM?​

The System Advisor Model (SAM) is a free techno-economic software model that facilitates decision-making for people in the renewable energy industry

SAM is developed by the National Renewable Energy Laboratory (NREL) with funds from the U.S. Department of Energy. The SAM development team collaborates with industry partners, NREL staff and interns, and other research organizations develop and enhance the model. The original solar models were developed in collaboration with Sandia National Laboratories and the University of Wisconsin's Solar Energy Laboratory.

What is TMY?​

A typical meteorological year (TMY) is a set of meteorological data with data values for every hour in a year for a given geographical location. The data are selected from hourly data for the full time period available, currently 2005-2020 in PVGIS5.2 and 2005-2016 in PVGIS5.1.

Asensi ohjelman testatakseni leikaantumista Enphasen microjen kohdalla. Samalla tein TMY tiedoston pääkaupunkiseudulle. Lumidataa en saanut säätietoihin. Samalla tuli testattua black/white mallistojen tehoeroa ja kannakeiden korkeuden / ilmatilan vaikutusta.

Edit: diagrammia kun katsoo niin likaantuminen (soiling loss) on merkitävin häviöden lähde.
