Two new metrics, Solar Volatility and Solar Deviation, are introduced to quantify the variability of PV output compared with expected output. These metrics are applied to the time series power data from over 1000 systems each around Los Angeles and Newark.
This paper defines “Solar Deviation” for a distributed solar PV system as the standard deviation of the (aggregated) differences between the observed amounts of power generated by the system at five minute intervals throughout a given day and the expected amounts of power generated by the system.
The power devices employed in various PV inverter topologies inevitably result in a redistribution of power losses within the system, particularly when the solar irradiance and ambient temperature are variable.
In the realm of solar energy systems, the reliability of inverters plays a pivotal role in overall performance and sustainability. This solar inverter reliability study aims to clarify the comparative reliability of two prevalent inverter types used in solar installations: microinverters and string inverters.
