SolarPanel

Description

The SolarPanel module allows to use long-term real-world solar energy harvesting traces in simulation, by including - a PV cell model that can be configured according to parameters that are typically available in datasheets, and - real-world solar irradiance traces from existing datasets (e.g., NREL for outdoor and ENHANTS for indoor environments).

Examples for solar irradiance traces and their format can be found in Harvesters/harvesting_data/SolarTraces/DATASET. They can be extended with additional custom traces or with traces downloaded from the mentioned datasets (see Readmes in the corresponding folders).

Parameters

Parameter	man./opt.	Value	Description
file	m	Filename	Filename of .json-File that contains the solar irradiation trace (e.g., DATASET/trace.json)
t_start	o	Time in seconds	Start time of harvesting trace for simulation (to cut beginning of full trace) (Default: 0)
t_max	o	Time in seconds	Total time of harvesting trace for simulation (to cut end of full trace and limit amount of stored data during simulation) (Default: max. trace length)
i_sc	m	Current in A	Short circuit current of solar panel (or single cell) at 1000 W/m2
v_oc	m	Voltage in V	Open circuit voltage of solar panel (or single cell) at 1000 W/m2
i_mpp	m	Current in A	Current at MPP at 1000 W/m2
v_mpp	m	Voltage in V	Voltage at MPP at 1000 W/m2
num_cells	o	Integer	Number of PV cells in solar panel (Default: 1)
connection	o*	"parallel" or "series"	Define how the PV cells are connected
log	o	Boolean	Define whether logging is enabled (Default: False)

* mandatory if num_cells > 1
